Spring tides occur during new and full moons when the sun and moon are aligned, causing their tidal bulges to constructively interfere and produce the largest difference between high and low tides. Neap tides happen at quarter moons when the sun and moon are at right angles, causing their tidal bulges to destructively interfere and result in a smaller tidal range. The tidal range is greatest when the moon is closest to Earth at perigee and Earth is closest to the sun at perihelion.

Tides notes ppt
The document discusses how the moon's gravitational pull causes Earth's tides. It explains that the moon, being closer to Earth than the sun, has a stronger tidal influence. The moon's gravity causes the oceans to bulge on both the near and far sides of Earth, resulting in two high tides per day. It also describes spring tides with extra high and low tides during new and full moons, and neap tides with less pronounced tides during half moons due to the sun partially offsetting the moon's gravitational pull.
Ocean current
Oceans are a vast body of salt water that covers almost three to fourths of the earth's surface.
Seas are smaller, found on the margins of the ocean and are partially enclosed by land.
Seawater:
High density, high heat capacity, colder, salty and slightly compressible (its volume decreases under pressure), thus its density increases with pressure.
Why is Ocean Circulation Important?
•Similar to winds in the atmosphere, they transfer significant amounts of heat from equatorial areas to the poles and thus play important roles in determining the climates of coastal regions.
•The ocean circulation pattern exchanges water of varying characteristics, such as temperature and salinity
•ocean currents and atmospheric circulation influence one another.
•in addition, they transport nutrients and organisms
Tides
Tides are caused by the gravitational attraction of the moon and sun on the oceans as well as the centrifugal force from the Earth's rotation. High tides occur where the moon is overhead, while low tides happen 90 degrees away, and both the moon and sun's gravitational pulls contribute to the regular rising and falling of sea levels, though the moon has a greater effect being closer to Earth.
Tides
Tides are the periodic rise and fall of ocean water levels caused by the gravitational forces of the moon and sun. The dominant force is the moon, as it is closer to Earth. This causes bulges in the ocean on opposite sides of Earth called high tides, with low tides occurring between them. The periodic rise and fall happens twice each day. Tidal ranges vary depending on the positions of the Earth, moon, and sun, causing spring tides with the largest ranges or neap tides with minimum ranges.
Volcano
A volcano is an opening in the Earth's crust through which magma and gases erupt. It consists of three main elements - a vent, conduit, and magma chamber. There are different types of volcanoes defined by their structure, including composite/stratovolcanoes with steep slopes built up of layers of pyroclastic material, shield volcanoes with broad dome shapes built up by fluid lava flows, and cinder cone volcanoes built from loose bits of ejected magma. Volcanic activity occurs at constructive and destructive plate boundaries, with different eruption styles depending on the tectonic setting and rate of pressure release.
Ocean tides, types and theories
The document discusses ocean tides and their causes. It explains that tides are caused by the gravitational pull of the moon and sun, which create two tidal bulges on Earth. The timing of tides is related to Earth's rotation and the moon's revolution, resulting in a tidal period of about 24 hours and 50 minutes. Tides can be semidiurnal (two high tides and two low tides per day) or diurnal (one of each per day), depending on coastal geography. Spring tides occur during new and full moons when gravitational forces are strongest, while neap tides happen at quarter moons with weaker forces.
3. Atmospheric circulation
The global atmospheric circulation system transports heat around the Earth's atmosphere and affects climate and weather patterns. It involves warm air rising at the equator and cold air sinking at the poles, creating circulation cells. Without this system, temperatures would become more extreme between the tropics and poles.
Eclipses - Solar and Lunar Eclipses
The document discusses lunar and solar eclipses. It explains that lunar eclipses occur when the Earth passes between the sun and moon, casting its shadow on the moon. Solar eclipses occur when the moon passes between the Earth and sun, casting its shadow on parts of Earth. Eclipses only occur when the sun, Earth, and moon are aligned on the same plane. The document provides details on the conditions required to see each type of eclipse and diagrams demonstrating the geometry of lunar and solar eclipses.

The document discusses lunar and solar eclipses. It explains that lunar eclipses occur when the Earth passes between the sun and moon, casting its shadow on the moon. Solar eclipses occur when the moon passes between the Earth and sun, casting its shadow on parts of Earth. Eclipses only occur when the sun, Earth, and moon are aligned on the same plane. The document provides details on the conditions required to see each type of eclipse and diagrams demonstrating the geometry of lunar and solar eclipses.
The Moon and Tides - What causes tides?
Tides are caused by the gravitational interactions between the Earth, moon, and sun. This causes two tidal bulges in the Earth's oceans, with one bulge facing the moon and the other on the opposite side. As the Earth rotates daily and revolves around its axis, different locations experience high and low tides depending on their alignment with the tidal bulges. Specifically, high tides occur when a location is aligned under the moon or opposite the moon, while low tides occur when a location is at a right angle to the tidal bulges.
Sun, Moon, and Earth system
The solar system is made up of the Sun, the planets that orbit the Sun, their satellites, dwarf planets and many, many small objects, like asteroids and comets. All of these objects move and we can see these movements. We notice the Sun rises in the eastern sky in the morning and sets in the western sky in the evening. We observe different stars in the sky at different times of the year.
Internal Structure of Earth
Deep parts of Earth are studied indirectly, however, largely through the branch of geology called geophysics
Tides and its significance
The document discusses tides, which are the regular rise and fall of ocean water levels caused by the gravitational forces of the sun and moon. It describes the different types of tides, including semidiurnal and mixed tides. Spring tides occur during new and full moons when sun and moon forces align to produce higher tides, while neap tides occur during half moons and have lower ranges. The dynamic tidal theory explains how factors like ocean basins, Coriolis forces, and friction influence tidal patterns. Tides are significant as they transport sediments, mix waters in estuaries, and can be harnessed for tidal power generation.
The Earth, Rotation and Revolution
The Earth has two movements: rotation and revolution. Rotation is the Earth spinning on its axis every 24 hours, causing day and night. Revolution is the Earth orbiting the Sun every 365 days, causing seasons and years. Due to these movements, different parts of the Earth receive varying amounts of sunlight, influencing climate zones and seasons. The tilt of the Earth's axis and its position in orbit also affect the length of daylight and temperature changes throughout the year.
Movements of the earth.
The document discusses the movements of the Earth, including its rotation on its axis and revolution around the sun. It notes that the Earth's rotation causes day and night and its elliptical revolution around the sun takes 365 days. It also describes how the tilt of the Earth's axis and its revolution cause seasons, with the northern and southern hemispheres experiencing opposite seasons at the same time. Summer occurs when a hemisphere is tilted toward the sun, and winter when it is tilted away.
Structure and Composition of the Atmosphere
The atmosphere is composed of gases, water droplets, and particles surrounding Earth. It has four main layers - the troposphere, stratosphere, mesosphere, and thermosphere - each decreasing or increasing in temperature with altitude. The troposphere is where weather occurs, extending 8-16km high. Above is the stratosphere where temperatures increase with little weather, then the mesosphere where temperatures decrease again up to 80km. The thermosphere is the outermost layer with increasing temperatures from 80km high. The atmosphere composition consists primarily of nitrogen, oxygen, argon, and trace gases. Water vapor is the most abundant variable gas.
waves and tides
Waves and tides are caused by the gravitational pull of the moon and sun. There are different types of waves including wind waves and tsunamis. Tides are the regular rising and falling of ocean water levels caused by lunar and solar gravitational forces. High tides occur when the gravitational pulls act in alignment and low tides occur when they are perpendicular. Tides are important because they allow for shipping in harbors and prevent freezing in cold weather ports.
The Moon
The Moon is Earth's only natural satellite. It has no atmosphere and its surface is marked by craters and dust. The same side always faces Earth. The Moon's diameter is about one quarter that of Earth and it has lower gravity and density than Earth. Temperatures vary greatly from 130°C during the day to -110°C at night. Large flat plains called maria cover parts of the near side, formed by ancient lava flows. Craters and long valleys called rilles are also features of its surface. The Moon orbits Earth about every 27 days in a cycle linked to eclipses.
Eclipses
1) Eclipses occur when one celestial body blocks the light from another. Lunar eclipses happen during a full moon when the Earth casts its shadow on the moon. Solar eclipses occur during a new moon when the moon passes between the Earth and sun.
2) There are three types of lunar eclipses - total, partial, and penumbral - and three types of solar eclipses - total, partial, and annular.
3) Eclipses do not occur every month because the moon's orbit is tilted relative to the Earth's orbit around the sun. Lunar eclipses are more frequent than solar eclipses.
Ice ages
An ice age is a period of long-term cooling where ice sheets and glaciers expand. The current ice age began 2.6 million years ago and there is evidence that previous ice ages occurred. Geological, chemical, and paleontological evidence support past ice ages. Factors that can influence ice ages include the positions of continents, uplift of land masses, ocean iron levels, atmospheric CO2 levels, and astronomical cycles like the Milankovitch cycle that affects seasonal temperatures.
Air Pressure
1. Air pressure is caused by the weight of the atmosphere and is exerted in all directions. It is measured using a barometer.
2. Wind is caused by differences in air pressure and is affected by pressure gradients, the Coriolis effect, and friction. Unequal heating of the Earth's surface creates pressure differences.
3. The atmosphere circulates in cells with air rising at the equator and sinking at the poles, driven by pressure and temperature differences. This circulation creates global wind patterns like the trade winds and westerlies.
Hydrosphere
The document summarizes key aspects of Earth's hydrosphere and hydrologic cycle. It describes the hydrosphere as including all of Earth's water found in oceans, glaciers, streams, lakes, soil, groundwater, and air. It also notes that Europa and possibly Ganymede and Enceladus may have subsurface oceans. Additionally, it provides details on the distribution and movement of water between the oceans, atmosphere, biosphere, lithosphere, and the water cycle which traces this movement between stores and spheres.
Atmospheric circulation
The document discusses different types of winds and factors that influence wind patterns. It explains that convection currents cause local winds like sea and land breezes as land and bodies of water heat and cool at different rates. Prevailing winds blow over long distances due to global wind patterns influenced by unequal heating from the sun and the Coriolis effect from the Earth's rotation. These winds are classified into belts and some regions experience seasonal monsoon winds as air pressures and temperatures shift between land and ocean areas.
Tides (Geology)
Tides are caused by the gravitational interactions of the Earth, Moon, and Sun. The Moon's gravity pulls more strongly on the side of Earth facing the Moon, creating tidal bulges in the ocean. When these bulges are closest to coastal areas, high tide occurs, and when they are furthest away, low tide occurs. The Sun also affects tides. Spring tides occur during a full or new moon when the Sun and Moon are aligned, creating higher high tides and lower low tides. Neap tides occur when the Sun and Moon are at right angles, resulting in weaker tides. Most places experience two high and two low tides each day.
Coastal hazard
This document summarizes various coastal hazards. It categorizes hazards as either rapid-onset (e.g. coastal flooding from storm surge or tsunamis) or slow-onset (e.g. coastal erosion, land subsidence, or saltwater intrusion). Rapid-onset hazards are caused by sudden events like earthquakes generating tsunamis or storms producing storm surge, while slow-onset hazards occur gradually over time from erosion, sinking land, or encroaching seawater. The document also discusses how human activities like dams, seawalls, and jetties can disrupt sediment flows and influence coastal changes. Mitigation measures proposed include protective infrastructure, emergency response improvements, and climate information services.
Earth Science. Hydrosphere ppt
The document discusses the four main systems that make up Earth: the atmosphere, hydrosphere, biosphere, and geosphere. It focuses on the hydrosphere, explaining that water covers 70% of the Earth's surface and is essential for life. It then describes the water cycle, in which water is in constant motion between the oceans, atmosphere, and land via evaporation, condensation, precipitation, and collection.
Solar and lunar eclipses
A "lunar eclipse" and a "solar eclipse" refer to events involving three celestial bodies: the Sun ("solar"), the moon ("lunar"), and the Earth. A lunar eclipse occurs when the Earth passes between the Moon and the Sun, and the Earth's shadow obscures the moon or a portion of it. A solar eclipse occurs when the Moon passes between the Earth and the Sun, blocking all or a portion of the Sun.
Internal structure of earth with repect to seismic waves
This document discusses the structure and composition of Earth's interior as revealed through seismic wave studies. It describes the major layers as follows:
The crust, which is thinner and denser under the oceans than continents. Below is the mantle, which extends to a depth of 2,890 km and is denser than the crust. The lower mantle has higher seismic wave velocities than the upper mantle. The core lies below the mantle, with the liquid outer core surrounding a solid inner core. Seismic waves have provided evidence of this internal structure.
Ocean waves lecture
Ocean waves are characterized by their amplitude, wavelength, frequency, and period. Amplitude refers to the height of the wave from still water level to the crest. Wavelength is the distance between two identical points on successive waves. Frequency is the number of waves passing a fixed point per second, while period is the time for one full wave cycle. Wave height depends on factors like fetch (distance over water the wind blows) and breaking occurs when the wave steepness exceeds about 1/7. Breaking waves can be spilling, plunging, or surging.
Let`S Talk About The Earths Tides
This document discusses the tides and how they are influenced by the moon's phases. It begins with an introductory activity to refresh knowledge of moon phases. It then explains that tides are caused by the gravitational pull of the moon and sun, which causes bulges in the oceans. Spring tides occur during full moons and new moons when gravitational forces are strongest. Neap tides occur during quarter moons and have weaker tides. The document includes diagrams and activities to illustrate these concepts. It concludes with assigning students into groups to create posters about different moon phases and their effect on tides.
Tide notes part 2
Tides are caused by the combined gravitational forces of the sun and moon on Earth's oceans. There are two types of tides: spring tides that occur during a new or full moon when the sun and moon are aligned, producing the highest high tides and lowest low tides; and neap tides that happen during a first quarter or third quarter moon when the sun and moon are at a right angle, resulting in smaller tidal ranges with higher low tides and lower high tides than normal.

Astronomy lunar phases eclipses and tides
The phases of the moon are caused by the changing positions of the sun, Earth, and moon relative to one another. A new moon occurs when the moon is between the Earth and sun so its night side faces Earth. A full moon happens when the moon is on the opposite side of Earth from the sun, so its full day side faces Earth. Eclipses occur when the sun, Earth, and moon align so that one passes in front of the other, casting a shadow. Lunar eclipses happen during a full moon when Earth blocks the sun's light from reaching the moon.

Tides are caused by the gravitational pull of the Moon and, to a lesser extent, the Sun. The Moon's gravity creates bulges in the Earth's oceans that result in high and low tides about every six hours. There are two types of tides: spring tides, which occur during a full moon or new moon and have the largest difference between high and low tides, and neap tides, which occur when the Sun and Moon are at right angles to each other and have a smaller difference between tides.

Tides lecture part one
The document summarizes tides and their causes. Tides are caused by the gravitational pull of the moon and sun as well as the centrifugal force created by Earth's rotation. This results in two high tides and two low tides per day in most places, with the timing of tides occurring later each day as the moon orbits Earth more slowly than Earth's rotation. The type and range of tides varies depending on location factors like latitude, water depth, and coastal geography.
Sun eclipse
The document is about a sun eclipse. It shows that during a sun eclipse, the moon creates a small shadow on Earth that allows only certain areas to see a total eclipse of the sun. The shadow blocks the sun's light in specific locations while other places still see partial or no eclipse at all.

Kipp earth sun moon
The document discusses topics relating to the Sun-Earth-Moon system and planetary motion. It describes how Earth orbits the Sun in an elliptical path, rotating on its tilted axis to cause day and night. The Moon orbits Earth, reflecting sunlight and exhibiting phases as its illuminated portion changes. Eclipses can occur when the Sun, Earth, and Moon align, blocking light. The planets are divided into inner rocky planets and outer gas giants, with characteristics like composition and moons described for each. Asteroids, comets, and meteoroids are also discussed, along with their origins and interactions with planets.
The Sun: Not Just Our Star
The sun is a huge glowing ball of gas at the center of our solar system that provides light, heat, and energy to Earth. It is made up primarily of hydrogen and helium and has a radius about 109 times that of Earth. The sun was formed around 4.6 billion years ago and will remain stable for another 5 billion years before expanding into a red giant. It emits electromagnetic radiation across the spectrum, including visible light and infrared that we experience as heat and light. Nuclear fusion in the sun's core converts hydrogen to helium and releases enormous amounts of energy.

Movements of ocean water
There are three main types of ocean water movements: waves, tides, and ocean currents. Waves are caused by wind moving over the water surface and move water horizontally towards and away from coasts. Tides are the regular rise and fall of sea levels caused by the gravitational pull of the sun and moon, occurring once or twice per day. Ocean currents constantly flow in definite paths and directions, and can be warm or cold currents depending on the temperature of the region they originate from.
Astronomy- Motion, eclipses, tides, moon
The document discusses planetary motion, eclipses, tides, and phases of the moon. It explains that planets orbit stars in ellipses rather than perfect circles, and that closer planets move faster due to gravity. It describes solar and lunar eclipses, noting that solar eclipses occur when the moon passes between Earth and the sun, while lunar eclipses occur when Earth passes between the sun and moon. It also discusses how the moon's gravity causes ocean tides, with high tide occurring when the moon is overhead or opposite the tide location. Finally, it outlines the phases of the moon as it revolves around Earth.
Water in the atmosphere and Weather Pattern
Fogged up windows and bad hair days are caused by humidity in the air. Water vapor condenses as clouds, dew, frost or fog depending on temperature. Clouds form through various processes and can be classified into categories like stratus, cumulus or cirrus clouds based on their shape and altitude. Air masses and fronts influence weather patterns as different air masses collide and interact.
The moon and tides
The document discusses various lunar phenomena such as micro moons, blue moons, blood moons, eclipses, and tides. A micro moon occurs when the full moon coincides with the moon's farthest point from Earth. There are three types of lunar eclipses defined as penumbral, partial, and total. Eclipses happen when the sun, moon, and Earth are aligned. Tides are influenced by the gravitational pull of the moon and sun, and there are two types of tides called spring tides and neap tides.
Moon Motions and Eclipses
The document summarizes the motions and phases of the Earth-Moon system. It explains that the moon orbits Earth over the course of about a month in an elliptical orbit, appearing larger when closer (perigee) and smaller when farther (apogee). The changing positions result in the phases of the moon as the illuminated side facing Earth waxes and wanes over the lunar cycle. Eclipses occur when the sun, Earth, and moon align, causing the moon to block the sun during a solar eclipse or Earth to block the sun's light during a lunar eclipse.
Eclipses And Tides
The document discusses different types of eclipses including solar and lunar eclipses. A solar eclipse occurs when the moon passes between the earth and sun, blocking the sun from view. A lunar eclipse occurs when the earth passes between the sun and moon, casting the moon in earth's shadow. The document provides details on the different types of solar and lunar eclipses as well as explanations for why eclipses do not occur every month and why the moon appears red during a lunar eclipse.

Tides
The document discusses the causes and patterns of ocean tides. It explains that tides are caused by the gravitational interactions between the Earth, Moon, and Sun. This results in two high tides and two low tides each day, known as semidiurnal tides. Spring tides occur during full moons and new moons when the gravitational forces are strongest, while neap tides occur during quarter moons when the forces are weakest. The Bay of Fundy experiences some of the largest tides in the world, with spring tides reaching over 15 meters high.
Sun, Earth, Moon System
This document discusses the relationships between planets, moons, and other celestial bodies. It explains that the Moon orbits the Earth and is considered our natural satellite. A satellite revolves around a planet. Lunar eclipses occur when the Moon passes behind Earth into its shadow, while solar eclipses happen when the Moon passes between Earth and the Sun. The Moon's phases are caused by varying amounts of sunlight reflecting off its surface due to its orbit around Earth. Tides are also influenced by the Moon's gravity, with high and low tides occurring regularly due to the positions of the Moon and Sun relative to Earth.
tides_DrSS.pptx
The document summarizes tides and their causes. Tides are the daily rise and fall of sea levels caused by the gravitational pull of the Moon and Earth's rotation. The Moon's closer proximity to Earth means it has a stronger gravitational pull than the Sun. This pull creates tidal bulges in the oceans on the sides facing and facing away from the Moon. As Earth rotates, different locations experience high and low tides passing through these bulges. Spring tides occur during full and new Moons when the Sun and Moon pull together, creating higher tides. Neap tides happen at half Moons when the Sun and Moon pull at right angles, resulting in lower tides.

Solarsystem
The document summarizes key facts about the solar system, Earth's motions, the relationship between the Earth, moon and sun, eclipses, ocean waves and tides. It notes that the sun contains 99.86% of the mass in the solar system. It also explains that Earth's rotation causes day and night and its axial tilt causes the seasons. The moon rotates and revolves at the same rate of 27.3 days, keeping the same side facing Earth. Eclipses occur when the Earth or moon block sunlight from each other. Tides are caused by the gravitational forces of the moon and sun and change in height between spring and neap tides depending on their positions.
Earth's moon
The moon rotates on its axis once every 29.5 days and revolves around Earth once every 29.5 days, keeping the same face pointed towards Earth. The changing positions of the moon relative to Earth and the sun cause the phases of the moon and tides on Earth. Features on the moon's surface include craters and flat dark areas called maria, which are large basins filled with hardened lava.
Earth's moon
The document discusses key characteristics and features of Earth's moon. It describes how the moon rotates on its axis once every 29.5 days and revolves around Earth, also taking 29.5 days. This locked rotation is why we always see the same face of the moon. The changing positions of the moon and sun relative to Earth cause the phases of the moon and create high and low tides. Eclipses occur when the moon or Earth block the sun's light. Craters and flat dark areas called maria are visible features on the moon's surface.
Ch 11- Lunar phases eclipses
The impact theory proposes that the Moon formed from the debris ejected into Earth's orbit after a Mars-sized body collided with Earth. The Moon rotates in sync with its revolution around Earth, always showing the same face. Its daily eastward movement against the stars is due to revolution, while its rising and setting is caused by Earth's rotation. The changing visible shape of the Moon, from new to full and back, is due to its position in its orbit around Earth. Lunar and solar eclipses occur when the Moon blocks the Sun or enters Earth's shadow, respectively, but not every month due to the Moon's tilted orbit. Tides are caused by the gravitational pull of the Moon and Sun, with spring
010 tides
Tides are caused by the combined effects of the gravitational pull of the Moon and the Sun and the centrifugal force as the Earth rotates. This results in two high tides and two low tides each day, with the tidal ranges varying in a monthly cycle from spring tides with the highest ranges to neap tides with the lowest ranges, depending on the relative positions of the Earth, Moon, and Sun. Tidal patterns differ around the world depending on location.
2 - 3 ocean tides - low & high
Gravity plays a key role in many natural phenomena. It holds planets, stars, and galaxies together through gravitational attraction. On Earth, gravity causes ocean tides as the gravitational pull of the Moon and Sun attract the oceans. This creates two high tides each day as the Moon and Sun's positions change. The highest tides occur during a full moon or new moon when the Moon, Earth, and Sun are aligned, magnifying their gravitational effects in what are called spring tides.
2. Tide Notes
Tides are long period waves in the oceans caused by the gravitational forces of the Sun and Moon. High tide occurs when the crest of the tidal wave reaches a location, while low tide is when the trough arrives. Flood tides bring water inland from the coasts at high tide, while ebb tides carry water back out to sea at low tide. The Moon has a stronger tidal influence than the Sun due to its closer proximity to Earth. This causes two high tides and two low tides each day as the Earth rotates through the tidal bulges created by the Moon's gravity.
Marine Tide Notes
Tides are long period waves in the oceans caused by gravitational forces from the Sun and Moon. High tide occurs when the crest of the tidal wave reaches a location, while low tide is when the trough arrives. Tides create flood currents during incoming tides and ebb currents during outgoing tides, with the strongest currents occurring near high and low tides. The Moon has a greater influence on tides than the Sun due to its closer proximity to Earth. This causes coastal areas to experience two high tides and two low tides every 24 hours and 50 minutes.
Tides
Tides are caused by the gravitational forces of the moon and sun interacting with Earth's oceans, which creates two bulges of water that result in two high tides and two low tides each day. The changing positions and distances of the moon and sun relative to Earth cause variations in tide heights and times. Spring tides occur during new and full moons when the sun and moon are aligned, producing the highest tides, while neap tides happen when the sun and moon are at right angles, resulting in lower tides.
Maz Kenz
Tides are caused by the gravitational pull of the moon and sun and the rotation of the Earth. The moon's gravity pulls the ocean waters closest to it, creating high tides, while the furthest waters experience low tides. Spring tides occur when the sun, moon, and Earth are aligned, producing the largest difference between high and low tides, while neap tides happen at a right angle and have smaller tidal ranges.
tides.pptx
The Moon's gravitational pull is the primary cause of tides on Earth. The Moon creates bulges in the Earth's oceans on the side facing it and on the opposite side due to having a stronger gravitational attraction being closer. As the Earth rotates, different places experience high and low tides as they come into alignment with these bulges. The Sun also influences tides through its gravitational pull, sometimes reinforcing and other times counteracting the Moon's effects. Spring tides occur during full and new moons when the Sun and Moon are aligned to produce higher tides, while neap tides have lower heights and occur during half moons when their pulls are at right angles.
sunearthmoonsystem PPT notes.ppt
The document discusses the rotation and revolution of Earth and the Moon. It explains that Earth rotates on its axis every 24 hours, causing day and night. It revolves around the Sun in an elliptical orbit over the course of a year. The Moon revolves around Earth, causing the phases of the Moon as it reflects sunlight. The positions of Earth, Moon, and Sun cause solar and lunar eclipses periodically.
12.1 earth, moon, sun
Early civilizations closely observed the sky and used celestial movements to track time and guide activities. It was later discovered that the Earth revolves around the Sun, while the Moon revolves around Earth. The Moon was formed from debris ejected after a giant impact between Earth and another planet. Its phases and gravitational pull are responsible for ocean tides and it has no atmosphere or erosion, leaving ancient craters visible.
Revision
The document discusses the relationship between the Earth, moon, and sun. It explains that the Earth's tilt and orbit around the sun cause the seasons to change. As the Earth orbits, different hemispheres are tilted toward or away from the sun, resulting in summer and winter. It also describes how the gravitational pull of the moon causes ocean tides, with the highest tides occurring during full moons and new moons. Additionally, it explains lunar and solar eclipses, noting that a solar eclipse can only occur during a new moon when the moon passes between the Earth and sun.
Notes eclipses lunar
The document discusses various topics relating to the moon and its effect on Earth, including the reasons for lunar phases, eclipses, tides, and more. It explains that the moon's phases are caused by its revolution around Earth and the amount of sunlight visible from our perspective. Tides are caused by differences in the moon's gravity pulling on parts of Earth. Spring tides have the greatest tidal range due to combined solar and lunar gravity, while neap tides have the lowest range.
Power point
Tides are caused by the gravitational forces of the Moon and Sun and the rotation of the Earth, rising and falling with approximately 12 hour periods and being influenced by near-shore terrain. Seasons result from the Earth's yearly orbit and axial tilt, causing changes in sunlight intensity that affect animal hibernation and migration and plant dormancy. The Big Bang theory proposes that the universe expanded from an extremely dense and hot state and continues expanding, carrying galaxies with it like raisins in an expanding loaf of bread.

Composing The Final Proposal
This document provides instructions for interns to complete and submit their final malaria treatment proposal. It guides them through writing an introduction paragraph by copying relevant information from their project summary. It then instructs them to state their design claim by describing the key aspects of the proposed treatment design. For the conclusion, interns are told to summarize why their design should be chosen, describe their design priorities and the trade-offs between criteria, and convince the reader their design is optimal despite the trade-offs. The document also reviews revising the entire proposal, including the three design decision paragraphs, before submitting.
Writing Design Decisions
1. Interns were instructed to review feedback from the project director on their outline and background research and discuss how to strengthen their design decision paragraphs with colleagues.
2. They were then directed to write the three design decision paragraphs for their proposal, using their outline, feedback, and other resources as guides.
3. Interns were reminded to save their work in progress but not submit, as they will continue working on the introduction and conclusion sections during their next workday. They should review tasks and determine if any unfinished work needs completion after hours.
Considering Design Decisions
The document discusses strategies for writing a strong proposal to address the problem of drug-resistant malaria, including focusing on one section of the proposal at a time, using an outline to organize evidence supporting design claims, and reviewing examples to understand how different parts fit together. Interns are asked to gather evidence by outlining their design decisions for three criteria related to minimizing drug resistance, side effects, and cost in order to receive feedback on their evidence and arguments.
Choosing An Optimal Design
This document outlines steps for interns to review design feedback, interpret how well their design addressed different criteria, and plan iterative testing to improve their design. Interns receive feedback letters evaluating their designs on criteria like minimizing drug resistance, reducing side effects, and lowering treatment costs. They annotate the letters and record notes in a feedback summary table, color-coding results as strongly, moderately, or weakly addressing each criterion. Discussing trade-offs between criteria helps interns prioritize areas for improvement and set targets for their redesign strategies, as it is difficult for one design to strongly address all criteria equally. The goal is to identify an optimal design through iterative testing and choice of priority among criteria.
Designing Malaria Treatments
Engineers at Futura are developing malaria treatments using an iterative design process and simulation tool called MalariaMed. Students practiced this process by running multiple iterative tests of simulated malaria treatment designs, recording the results, and analyzing the data to identify the strongest design. The best design would minimize drug resistance and side effects while keeping costs low, without increasing the malaria parasite population. After analyzing all their results, students selected one design to submit to their project director for feedback on how to further improve their treatment design.
Exploring Antimalarial Drugs
The document discusses exploring antimalarial drugs to treat malaria. It describes running tests in MalariaMed to investigate how changing the drug type, dose size, and number of treatment days affects various criteria like the total parasite population, drug resistance, patient side effects, and total cost. The tests show that using a larger dose or more days of treatment generally reduces the parasite population more but increases drug resistance faster. In contrast, a smaller dose or fewer days reduces side effects and cost but risks allowing more parasites to survive and the population increasing. Using multiple drugs sequentially is suggested as a way to minimize drug resistance.
Understanding Drug Resistance
Using a single drug treatment for malaria results in a shift in the parasite population toward increased resistance to that drug over time. Testing different single-drug treatments in the MalariaMed model showed that resistance developed quickly when only one drug was used. Combining multiple antimalarial drugs is preferable to delay the development of resistance compared to reliance on a single drug.
Writing A Scientific Argument
This document provides guidance to students on developing a scientific argument to explain why stickleback populations changed over 13 generations. It instructs students to use a Reasoning Tool template to organize their claim, evidence, and reasoning. Students are told to annotate their Reasoning Tool by circling their strongest evidence, crossing out unrelated evidence, and connecting related evidence with arrows. They then write an argument referring back to the Reasoning Tool and using suggested sentence starters to clearly articulate their reasoning. For homework, students finalize and revise their written arguments.
Engaging In A Science Seminar
The document describes a classroom lesson where students will participate in a Science Seminar discussion to answer the question "What caused the stickleback population to have less armor and become faster?". The students will be split into two groups - one to lead the discussion in the inner semicircle and one to listen and take notes in the outer semicircle, and they will switch roles halfway through. The goal is for the students to use the evidence cards and their knowledge to build the best explanation for why the environmental change caused the stickleback population to change.
Examining Evidence About Sticklebacks
This document describes a science seminar about stickleback fish. It includes sections where students annotate passages about sticklebacks, are introduced to how the population has changed over generations from having more armor plates to fewer, and examine evidence cards about stickleback traits, environment, and lifespan. The goal is for students to analyze the evidence and determine which of two claims is best supported about what caused the changes in the stickleback population.
Wrapping Up The Newt Mystery
Mutations can introduce new traits into a population. A mutated trait will become more common over generations if it provides an adaptive advantage in the environment. According to the document, a mutation introduced a trait for high poison levels in newts 50 generations ago. When snakes were introduced to the environment 40 generations ago, the high poison levels provided an adaptive advantage by preventing snakes from eating the newts. As a result, the highly poisonous trait became the most common trait in the newt population over many generations.
Mutations In a Population
This document discusses mutations in populations and how traits created by mutations may become more or less common over generations. It describes an activity using a simulation where students will investigate whether mutations can introduce non-adaptive fur traits into an ostrich population in a cold environment. The simulation allows students to observe the population over 50 generations with mutations turned on and analyze changes in fur traits, to see if low-fur traits introduced by mutation become more or less common. Key points emphasized are that mutations occur randomly, can create adaptive, non-adaptive or neutral traits, and adaptive traits will become more common while non-adaptive traits will become less common over time.
Introduction to Mutations
This document describes a lesson about how new traits can emerge in populations through mutations. Students will read an article on mutations and discuss how mutations could explain a new poison level trait appearing in newt populations over time. They will then use a simulation to explore how mutations can introduce variation that allows a population to adapt when the environment changes. By running the simulation with and without mutations turned on, students can compare the outcome for a population of ostrilopes in a cooling environment and see the impact of mutations on the population's ability to survive.
Reviewing Key Ideas About Natural Selection
The document discusses natural selection and reproduction through a lesson on newts. It explains that traits are passed down from parents to offspring, and that individuals with adaptive traits are more likely to survive and reproduce, passing on those traits. The lesson has students complete different activities to understand how adaptive traits like high poison levels in newts became more common in a population over time through this process. It concludes with a self-assessment for students to reflect on their learning.
The Deadly Dare
The document discusses a chapter about natural selection and reproduction. It includes sections about warming up and reading activities for students, including reading an article called "The Deadly Dare" about how poison helps rough-skinned newts survive and how it became more common over generations through natural selection. The chapter asks how some traits become more common over many generations while others become less common.
Reasoning About The Newt Mystery
The document describes students rereading an article on how a newt population evolved to have higher levels of poison over generations. It has the students use evidence from histograms and the article to complete a reasoning tool connecting the evidence to a claim about why the trait for increased poison became more common. The reasoning tool is used to help the students write a scientific argument explaining their claim to share with others.
Survival and Reproduction
The document discusses natural selection and how traits become more or less common over generations within populations. It describes an investigation using a simulation of ostrilopes with different color traits. Data was collected on how many offspring each color trait produced. The data showed that ostrilopes with the yellow color 7 trait reproduced more on average and became more common in the population over time, while ostrilopes with traits like blue 1 and yellow 10 that did not provide camouflage reproduced less and became less common. This occurred because traits that helped ostrilopes survive longer, like yellow 7, allowed them to reproduce more and pass on their genes more frequently.
Reproduction and Traits
The document describes a simulation activity where students use a natural selection simulation to gather evidence about how traits are passed from parents to offspring during reproduction. The simulation shows that while offspring generally inherit traits from their parents, over multiple generations of reproduction the frequency of traits in a population can change as some traits become more or less common than others. The activity provides evidence to refute the claim that reproduction always produces offspring with adaptive traits, since in the simulation non-adaptive traits were still passed down from parents to offspring.
Explaining Changes in Trait Distribution
The document summarizes a lesson on explaining changes in a population of rough-skinned newts over time based on evidence. It discusses:
1) Having students review evidence that the newt population changed, with more highly poisonous individuals now than 50 generations ago.
2) Connecting this to the fact that snakes became part of the newts' environment between the first and second data samples.
3) Concluding that snakes likely caused high poison levels to become an adaptive trait, leading to more poisonous newts over time through natural selection.
Adaptive Traits
This document describes an investigation of how traits change over time in different environments using a simulation of ostrilopes. Students observe an ostrilope population in two environments - one with a predator where being yellow provides camouflage, and one without a predator. In the environment with a predator, the population shifts to being entirely yellow over time as yellow ostrilopes are more likely to survive. In the environment without a predator, the trait distribution changes little. This provides evidence that yellow color is only adaptive in an environment where it provides camouflage from predators. The document then discusses using a modeling tool to predict how traits in a thornpalm population might change over time in response to environmental factors like

The Moon and Tides - Spring vs. Neap Tides
- 1. SPRING vs. NEAP TIDES
- 2. The lunar day Tidal bulges follow the Moon as it rotates around Earth Lunar day is 50 minutes longer than a solar day because the Moon is moving in its orbit around Earth
- 3. The Earth’s rotation pushes the tide ahead of the moon HighTide Pushed Ahead of Moon The interaction between the Earth’s rotation pushing the tides ahead of the moon and tidal forces squeezing the tides toward the moon is slowly slowing down the rotation of Earth.
- 5. Relative sizes and distances of the Earth, Moon, and Sun The Sun is much more massive than the Moon but much further away Solar bulges are 46% the size of lunar bulges
- 6. Effect of elliptical orbits Tidal ranges are greater when: • The Moon is at perigee (point closest to the Earth) • The Earth is at perihelion (point closest to the sun) The sun also affects tides. The combined forces of the sun and the moon on Earth result in tidal ranges that vary based on the positions of the three bodies. A tidal range is the difference between levels of ocean water at high tide and low tide.
- 7. The monthly tidal cycle (29.5 days) About every 7 days, Earth alternates between: Spring tide • Alignment of Earth-Moon-Sun system in straight line. • LUNAR PHASE • New Moon or Full Moon • Lunar and solar bulges constructively interfere • Large tidal range Neap tide • Earth-Moon-Sun system at right angles • LUNAR PHASE • 1st Quarter or 3rd Quarter • Lunar and solar bulges destructively interfere • Small tidal range
- 10. Different types of tide Sun Earth Moon Spring tides occur when the sun and moon are in a straight line The tidal range is typically highest during spring tides…meaning locations will have a higher high tide and a lower low tide. 10
- 11. Different types of tide Neap tides occur when the sun and moon form a right angle with Earth Smaller difference between high and low tides. Low tides are typically higher than normal and high tides are lower than normal Earth Moon Sun 11
