Maps And Globes Are Models Of The Earth
1. Maps and globes are models that represent features on Earth's surface. Maps show natural and human features from an above view, while globes show Earth as seen from space with accurate sizes and shapes.
2. Maps use symbols to indicate different land features such as mountains, plateaus, and plains. They also use scales and legends to relate distances on maps to actual distances and explain symbols.
3. Latitude and longitude lines are used to locate positions on Earth, with latitude measuring distances north and south of the equator and longitude measuring distances east and west of the prime meridian.
Models of the Earth - Mapping
This document discusses models of the Earth and methods for finding locations on its surface. It explains that the globe is a spherical representation with no top or bottom and uses the Earth's rotation as a reference point. Latitude and longitude are used to specify locations, where latitude is the distance north or south of the equator and longitude is the distance east or west of the prime meridian. Various map projections like Mercator and conic are described which allow depicting the spherical Earth on a flat surface.
Moon, Sun, And Seasons
The document discusses how the height of the sun and moon in the sky changes with the seasons. It provides data on the noon altitude of the sun and maximum altitude of the moon every few days for one year. The data is to be graphed to show the seasonal patterns, with the full moon's behavior mirroring the sun's. Analysis questions examine when the sun and moon appear at the same altitude, how new moons relate to the sun, and what seasons are best for seeing low, orange "honeymoon" full moons.
The earth.
The document discusses key facts about the Earth's movements and geographic coordinate system. It notes that the Earth is the third planet from the sun in our solar system. It rotates on its axis approximately every 24 hours, causing day and night, and revolves around the sun over the course of 365 days, causing seasons. The document also describes how latitude and longitude are used to locate positions on the Earth's surface, with latitude measuring distances north and south of the equator and longitude measuring distances east and west of the prime meridian.

Climate graphs are introduced which show average monthly rainfall and temperatures on bar and line graphs. An example climate graph is provided for San Antonio.
Graph of Altitude vs. Pressure and Temperature
This document provides instructions for graphing the layers of the atmosphere by altitude versus pressure and temperature. It tells the reader to graph altitude versus pressure first, ignoring temperature, then to graph altitude versus temperature, ignoring pressure. Finally, it instructs them to identify the layers of the atmosphere - thermosphere, mesosphere, stratosphere, and troposphere - on the graphs.
~~ Latitude in astrology ( gooogle.com) ~~
This document discusses the importance of including latitude in astrological interpretations. Latitude refers to the position of celestial bodies north or south of the ecliptic plane. The author argues that latitude provides missing context, as the same astrological sign can occur in both the northern and southern hemispheres. Dividing latitude into zones, similar to how longitude is divided into the 12 astrological houses, could provide more detailed analysis. Incorporating latitude would make astrological assessments more three-dimensional and location-specific. The document also explores how latitude projections translate between the ecliptic and terrestrial spheres.
Weather instruments
The document discusses weather and weather forecasting. It defines weather as the condition of the atmosphere at a particular time and place. It describes some of the instruments used by meteorologists to study and predict weather, such as thermometers, barometers, and weather satellites. It notes that the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) provides weather forecasts and advisories for the Philippines.

The Seveso III Directive lays out rules to prevent major industrial accidents involving dangerous substances and limit their consequences. The COMAH Regulations 2015 implement Seveso III in the UK. Key changes in COMAH 2015 include classifying sites based on CLP instead of previous schemes, requiring basic site information to be publicly available electronically, and increased cooperation between COMAH and non-COMAH sites. The anaerobic digestion industry could potentially be impacted if biogas or digestate meet Seveso III classifications as dangerous substances, in which case sites would need to comply with COMAH duties like control measures and emergency response plans.

Intro to Antarctica
This document provides an introduction to Antarctica and the Antarctic region. It explains that Antarctica refers to the continent, while Antarctic refers to the entire southern polar region including surrounding oceans. Most of Antarctica is covered by over 2 km of snow and ice, and large glaciers flow toward the coast, forming ice shelves over the ocean. The polar regions are colder than other areas due to the low angle of incoming sunlight, which provides less energy. Additionally, the polar night during winters leads to long periods without any sunlight. Compared to the Arctic, Antarctica experiences colder average temperatures because it is surrounded by cold ocean currents that do not mix with warmer waters, its higher average elevation, and its position as a continental landmass surrounded by ocean

Lab #2:
Sun Angles, Daylength, Insolation, and Temperature Patterns
Insolation
The sun is the single most important source of energy on the surface of the Earth as well as the atmosphere.
The distribution of the Earth’s atmospheric phenomena and climate patterns, as well as the distribution of its ecosystems, are significantly influenced by the distribution of incoming solar radiation.
In heating the Earth’s atmosphere, visible light is the most important part of the sun’s electromagnetic spectrum.
This exercise examines sun angle and intensity of insolation, daylength and temperature patterns on the earth’s surface.
These variables are examined as they interrelate on the Earth’s surface over the course of a year.
Sun Angle
Because solar energy received by the earth follows essentially parallel pathways, and because the earth is spherical, at only one place on the earth’s surface can the sun’s rays strike vertically (this is known as the
subsolar point
).
In other words, at only one place at any one time can the sun appear directly overhead.
This occurs at
solar noon
when the sun reaches the highest position in the sky for that day.
Because of the earth's limited axial tilt, the sun can appear directly overhead at the
subsolar point
at a relatively narrow range of latitudes over the course of a year (between 23.5° N and 23.5° S).
An important relationship exists between latitude and the angle of the
noon
sun.
On the equinoxes (on March 21 or 22 and September 21 or 22) the sun’s rays are perpendicular to the earth at the equator.
Those same rays would also be tangent at both of the poles, so that the sun would appear only on the horizon at those locations.
On the same dates an observer at 30° N would record a sun angle of 60° above the southern horizon.
Remember, the sun is 90° to the observer at the equator, minus the latitude of 30° (30° of arc) which equals 60°.
This is called the
angle of incidence
, or sun angle.
The angle of incidence decreases by 1° for every degree of arc of latitude between the observer's position and the location where the sun’s rays are vertical.
This rule is the same for the other times of the year but is complicated by the earth's
declination
–the shift in angle when the sun's rays are not perpendicular to the equator.
If the declination is 10° S, this means that the sun's rays are vertical at 10° S and an observer at 30° N would see the sun at 50° above the horizon 90-40 or 90-(30+10).
Use the formula:
angle of incidence = 90° - (latitude in degrees + declination in degrees*)
* If the declination is in the same hemisphere as the observer, subtract this from latitude.
Example:
Seattle (47° N) on December 21 (23.5° S) would be:
90° - (47 + 23.5)
90° - (70.5) = 19.5°
Thus the angle of incidence for Seattle on December 21 is 19.5°
Note:
Keep in mind that solar noon is not the same as noon on our clock or watch because we are on standard time and typically, daylight s.

At the top of your screen, you should see a diagram of Earth’s orbit around the sun. A white “X” on the rotating Earth indicates the location of someone standing at 45 degrees north latitude.
In the lower right corner of the orbit window is a diagram showing the angle of sunlight that hits Earth at that time of year at that latitude.
To the far right of the orbit window is a thermometer indicating the average temperature at that time of year at that latitude.
Finally, below the orbit window, you should see an image of the landscape at that same latitude at the time of year on the orbit window.
Allow the animation to run for one full orbit of the Earth around the sun without changing any of the initial settings (the angle of inclination should be zero degrees).
Looking at the landscape view, describe the path of the sun in the sky throughout the year (you can click on “Trace Sun’s Path” in the control panel to make this easier to discern).
Describe any changes in sunlight angle in summer, spring, winter, and autumn.
Describe any changes in average daily temperature in summer, spring, winter, and autumn.
Change the inclination angle to 23 degrees (this is Earth’s actual angle of inclination). Let the animation run for a full orbit of the Earth around the sun.
Describe the path of the sun in the sky throughout the year (again, you can click on “Trace Sun’s Path” in the control panel to make this easier).
Describe the changes in sunlight angle in summer, spring, winter, and autumn.
Describe the changes in average daily temperature in summer, spring, winter, and autumn.
Do these simulated observations correspond with your real-life experience of average temperatures in these seasons? Why or why not?
Leave the inclination angle at 23 degrees but move the Earth (you can “drag” it with your cursor) to its winter solstice position. As you move the Earth around its orbit, you will see labels appear in the lower left-hand side of the orbit window. Hit “stop” when you are in the winter solstice position. Using the landscape window, approximate the number of hours of sunlight and night.
Sunlight hours:
Night hours:
Leave the inclination angle at 23 degrees but move the Earth to its summer solstice position (see lower left of orbit window for that label). Using the landscape window, approximate the number of hours of sunlight and night.

Night hours:
Leave the inclination angle at 23 degrees but move the Earth to its autumnal and then spring equinox positions .
Ncert earth
The document discusses latitudes and longitudes on a globe. It describes how the globe is tilted on its axis with the North and South poles. It discusses the equator line and parallels of latitude that run parallel to it. Important parallels mentioned include the Tropic of Cancer, Tropic of Capricorn, Arctic Circle, and Antarctic Circle. It also discusses longitude lines and the Prime Meridian that passes through Greenwich, England. Time zones are based on longitude, with places east of the Prime Meridian being ahead in time and places west being behind.
Unit 1 wiki
This document provides an overview of key geographic concepts including:
- The Earth's movements and geographic coordinates defined by lines of latitude and longitude that form a grid system.
- Common map projections like Mercator and Peters that translate the spherical Earth onto a flat surface, inevitably distorting aspects of size, shape or area.
- Different types of maps including topographic maps depicting physical features and thematic maps focused on topics like politics, climate or economics.
- Time zones which divide the globe into 24 hourly sections measured at 15 degree intervals based on the Prime Meridian.
Latitudes and longitudes
1. A globe is a miniature model of the Earth that shows its true spherical shape and allows locations to be precisely pinpointed using lines of latitude and longitude.
2. The globe can be rotated on its axis and is marked with the Equator, Tropic of Cancer at 23.5° N, Tropic of Capricorn at 23.5° S, and other important parallels of latitude. Meridians of longitude divide the globe into Eastern and Western hemispheres.
3. Locations are specified using their latitude and longitude coordinates - degrees north or south of the Equator, and degrees east or west of the Prime Meridian passing through Greenwich, England. This grid system allows any place
Science 7-4th Quarter The Philippine Environment
The document discusses the location of the Philippines using latitude and longitude. It describes how latitude and longitude can be used to pinpoint the specific location of Manila at 14°N, 121°E. While a single point can locate a city, describing the location of a country requires indicating the range of latitudes and longitudes that define its boundaries, which can be approximated using a rectangular boundary. The document also provides background on lines of latitude and longitude, and names important parallels that delineate climate zones around the world.
Lab two 2012 fall
The document discusses Earth-Sun relationships and how the position of the subsolar point changes throughout the year due to the tilt of Earth's axis and its elliptical orbit. It also discusses equinoxes, solstices, and how an analemma can be used to determine the subsolar point and solar noon for any date. Topographic maps and how to measure distances and road lengths using map scales are described. The use of compasses to determine direction of travel and current position via landmarks is explained.
Unit 1 - Earth in space
The document summarizes key information about planet Earth and its place in the solar system. It describes Earth's structure, including the atmosphere, hydrosphere, and lithosphere. It also discusses Earth's rotation and revolution around the sun, which causes seasons. The document explains how to locate places using latitude and longitude coordinates on maps and read different types of maps. It provides details on time zones and how the Earth is divided for time.
Earth sun relationship
The Earth-Sun relationship affects climate in the following ways:
1. The Earth's 23.5 degree tilt causes uneven heating and results in seasons as the tilt changes in relation to the Sun throughout the year.
2. The Tropics of Cancer and Capricorn mark the beginning of summer and winter in the Northern Hemisphere when the Sun's rays directly strike them.
3. Areas above 66.5 degrees north and south latitude experience extremes of 24 hours of daylight or darkness depending on the season.
Earth and sun relationships
1) The Earth revolves around the sun in an elliptical orbit over the course of 1 year, and its axial tilt of 23.5 degrees relative to the orbital plane causes the seasons.
2) As the Earth revolves, its hemispheres alternate between tilting towards and away from the sun, resulting in the summer and winter seasons in each hemisphere.
3) An analemma diagram can be used to determine the position of the subsolar point, solar noon time, and solar altitude for any location on Earth on any given date throughout the year.

The giving tree
The Giving Tree tells the story of a boy and a tree over many years. As the boy grows up, he returns to the tree asking for things: first for apples to sell, then branches to build a house, and finally her trunk to make a boat. Each time, the tree gives up parts of herself so the boy can get what he needs to be happy. In the end, when the boy is old and tired, all the tree has left is an old stump, but she offers even that for the boy to rest on, finding happiness in continuing to give of herself to help the boy.
World climatezones 2
The document discusses how latitude affects climate by dividing the Earth into climate zones. The tropics lie between the Tropic of Cancer and Capricorn and experience a warm, wet-dry seasonal climate. Temperate zones between the tropics and polar circles experience four distinct seasons. Polar zones within the Arctic and Antarctic circles experience very cold temperatures year-round. Latitude determines the climate zones because the Sun's rays hit different areas of the Earth at different angles, losing more heat the farther from the equator they travel.

World climatezones 2
- 1. - World Climate Zones How Does Latitude Affect Climate? Created by: The Poole Pages Core Knowledge BCP – 5th Grade September Geography – Lesson 2
- 2. World Climate Zones How Does Latitude Affect Climate? First of all, what is climate? Climate is defined as the weather pattern of an area over a long period of time. So, when we talk about World Climate Zones, we’re saying that different areas of the earth have similar climates, or weather patterns. Today, we’re going to focus on the climate zones that are defined by latitude. Grab your World Map, because you need to mark some important lines of latitude on it that will help you understand this better. You’ll also need red, blue, green, orange, purple, and brown, markers, crayons, or colored pencils. Let’s go! Find the equator on your map. This is located at 0 degrees latitude. Trace over the equator with red. Now, in the bottom margin, make a map key. Write ‘equator’ and put a red square next to it. Now, find the Tropic of Cancer located at 23.5 degrees N. This exact line of latitude isn’t on your map, so just estimate where it should be. Draw a line on your map in blue. You can use a ruler to make it straight. Add ‘Tropic of Cancer’ to your map key with a blue square next to it. Next, find the Tropic of Capricorn located at 23.5 degrees S. Again, this exact line of latitude isn’t on your map, so just estimate. Draw a line to represent the Tropic of Capricorn in blue. Add ‘Tropic of Capricorn’ to your map key with a green square next to it. Now you need to locate the Arctic Circle. This is located at 66.5 degrees N. Estimate where it should go, and draw an orange line on your map. Add ‘Arctic Circle’ to your map key with an orange square. Only two more to go…stay with me! Find the Antarctic Circle located at 66.5 degrees S. Estimate where it should be, and draw a purple line on your map. On your map key, add ‘Antarctic Circle’ with a purple square. OK…last one! Do you know where the North and South poles are? Of course you do! They’re located at 90 degrees N and 90 degrees S longitude. Draw a brown circle at each of these locations and label them ‘North Pole’ and ‘South Pole’. Then add ‘Poles’ to your answer key with a brown square.
- 3. Whew! We’re done marking all of those important lines of latitude on your map. Now, let’s find out why you needed to do that. At the top of the first page, under World Climate Zones, it says ‘How does latitude affect climate?’ Take a look at this picture…it will help explain. Did you notice that the same lines of latitude that you marked on your map are also marked on this one? That’s because these climate zones are defined by lines of latitude. OK…take a look at those yellow arrows. They represent the sun’s rays hitting the earth. The rays that hit the earth near the equator have the shortest distance to travel, so they don’t lose much heat (or energy) before they get there. The area of the earth closest to the equator will therefore be the warmest. The area of the earth between the equator and the Tropic of Cancer, and the equator and the Tropic of Capricorn are called the Tropical Zones. The Tropical Zones are very warm, with only two seasons: a wet season and a dry season. As the earth curves away from the sun (at the Tropic of Cancer in the northern hemisphere, and the Tropic of Capricorn in the southern hemisphere), the sun’s rays take longer to get to the earth’s surface. By the time they get there, they don’t contain as much heat. So this area of the earth will be cooler than the area closest to the equator. The areas of the earth between the Tropic of Cancer and the Arctic Circle in the northern hemisphere, and the Tropic of Capricorn and the Antartic Circle in the southern hemisphere, are called the Temperate Zones. In the Temperate Zones there is a wider temperature range, and most areas experience the four seasons of winter, spring, summer, and fall.
- 4. The areas of the earth that are furthest from the sun (shown by the Arctic Circle and the Antarctic Circle) will be the coldest. This is because the sun’s rays take the longest to reach this area, so they’ve lost the most heat (or energy). The areas north of the Arctic Circle and south of the Antarctic Circle are called the Polar Zones. The Polar Zones stay very cold all year round and at certain times of the year has either 24 hours of daylight or 24 hours of darkness. ** Mark each of these zones on your World Map *** Awesome…now you know what you need to know about how latitude affects climate! What should you do now? 1. Make sure that your name is on your map. 2. Check your map to be sure that you marked all of the important lines of latitude and added them to your map key. 3. Be sure that you marked the tropical, temperate, and polar zones in the correct locations. 4. Give yourself a pat on the back and tell yourself, “Self…you’re goooood!” 5. Turn in your map.
