Humidity is the amount of water vapor in the air. The higher the temperature, the more water vapor air can hold. Relative humidity compares the actual amount of water vapor in the air to the total amount it can hold at that temperature. When the air reaches 100% relative humidity and can hold no more water vapor, any additional water will condense into a liquid, which occurs at the dew point temperature.

It also explains humidity measurement using water mixing ratio and relative humidity. Finally, it defines condensation as water changing from gas to liquid phases, and describes how it occurs in the atmosphere through cooling of warm air as well as at ground level as fog.
Climate Factors Ppt
The document discusses six main climate factors:
1) Latitude - The distance north or south of the equator determines temperature, with polar regions being cooler and tropical regions being warmer.
2) Altitude - Higher elevations experience cooler temperatures as air loses heat as it rises.
3) Land-Water Relationship - Large bodies of water moderate temperatures while land experiences more temperature variation.
4) Mountain Barriers - Mountains block moisture-carrying winds, creating wet and dry sides.
5) Ocean Currents - Ocean currents influence wind temperatures and rainfall along coasts.
6) Prevailing Winds - Global wind patterns are driven by differences in land and sea temperatures.
Climatic zones
The document discusses the three main climatic zones of the Earth: the Tropical Zone, Temperate Zone, and Polar Zone. It provides examples of countries located in each zone and describes some of the key climate characteristics and seasons of each zone. It also discusses the lifestyles and means of survival of nomadic peoples and Eskimos who inhabit the Polar Zone regions.
Moisture , cloud and precipitation
This document discusses moisture, clouds, and precipitation. It defines key terms like water vapor, humidity, dew point, and cloud formation processes. Water vapor is the gas form of water that is always present in the air. Clouds form through convection, mountain lifting, or air mass movement when warm moist air rises and cools, causing water vapor to condense into liquid water droplets or ice crystals. Clouds are classified by height and shape into high, middle, and low clouds. Fog forms near the earth's surface when moisture condenses from vapor to liquid form due to temperature differences.
Weather disturbances
This document discusses different types of weather disturbances including typhoons/hurricanes, tornadoes, and tsunamis. It provides details on the characteristics and formation processes of each disturbance. Typhoons and hurricanes are tropical storms that form over warm ocean waters and have wind speeds over 74 mph. Tornadoes develop rapidly over land and have shorter lifespans than cyclones. Tsunamis are large ocean waves caused by underwater earthquakes, volcanic eruptions, or landslides that can cause catastrophic damage when reaching land.
What is Humidity Presentation PDF
This document defines several key terms related to humidity:
- Humidity refers to the amount of water vapor in a gas. It can be expressed in terms of absolute humidity, relative humidity, and dewpoint.
- Absolute humidity is the actual amount of water vapor per liter of gas, measured in mg/L. Relative humidity expresses the amount of water vapor as a percentage of the maximum the gas can hold at a given temperature. Dewpoint is the temperature at which the gas reaches 100% relative humidity.
- The maximum amount of water vapor a gas can hold depends on temperature - the warmer the gas, the more water vapor it can hold before reaching saturation.

- Humidity refers to the amount of water vapor in a gas. It can be expressed in terms of absolute humidity, relative humidity, and dewpoint.
- Absolute humidity is the actual amount of water vapor per liter of gas, measured in mg/L. Relative humidity expresses the amount of water vapor as a percentage of the maximum the gas can hold at a given temperature. Dewpoint is the temperature at which the gas reaches 100% relative humidity.
- The maximum amount of water vapor a gas can hold depends on temperature - the warmer the gas, the more water vapor it can hold before reaching saturation.
Humidity
The document discusses different ways of measuring humidity, including absolute humidity, specific humidity, mixing ratio, vapor pressure, relative humidity, dew point, and how they relate. It explains that absolute humidity is a measure of the mass of water vapor per unit volume of air. Specific humidity and mixing ratio compare the mass of water vapor to the total mass or dry mass of air, respectively. Relative humidity compares the actual vapor pressure to the saturation vapor pressure at a given temperature. Dew point is the temperature at which air becomes saturated. High dew points indicate higher water vapor content in the air.
WATER IN ATMOSPHERE
1) Water exists in the atmosphere in solid, liquid, and gaseous forms. Water vapor accounts for around 4% of the atmosphere and plays an important role in determining weather through condensation and precipitation.
2) The amount of water vapor present in air is known as humidity, which is measured in terms of absolute or relative humidity. Evaporation from oceans and other water bodies adds water vapor to the atmosphere.
3) When air reaches its dew point temperature, water vapor condenses to form precipitation like rain, snow, sleet or hail which then falls to the Earth's surface through processes like convectional, orographic or frontal rainfall. The distribution of rainfall varies globally depending on factors like
Air Temperature & Pressure
This document discusses the properties of gases and air. It explains that gases have mass and take up space, have faster moving molecules than solids and liquids, expand to fill their container, have molecules spaced far apart with no bonds or fixed shape, and can be compressed. It then discusses the composition of air, temperature, pressure, density, humidity, and other gas properties.
Humidity and temperature
This document discusses various aspects of water in the atmosphere and how it relates to meteorology. It covers the water cycle and how water changes state between solid, liquid, and gas through processes like melting, evaporation, condensation, and sublimation. It also defines key humidity terms like relative humidity, saturation, and dew point. Relative humidity depends on both the air temperature and its water vapor content compared to the maximum it can hold at a given temperature.
Clouds
Clouds form when warm air rises and cools, reaching the dew point where water vapor condenses into liquid water or ice droplets. There are three main cloud types - cirrus, stratus, and cumulus - which are classified based on their altitude and appearance. Clouds can combine elements of these types and bring weather like rain or storms. Common cloud types include cumulonimbus thunderheads and nimbostratus rain clouds.
L.Sulollari. ppt for kids - topic -weather
The document summarizes different components of weather including clouds, wind, rain, temperature, and thunderstorms. Clouds are formed from tiny water or ice droplets that float in the air and appear white when they reflect sunlight. Wind is moving air produced by uneven heating of the Earth's surface. Rain forms as warm air holding water vapor rises and cools, causing water droplets to collect into clouds that become heavy and fall as rain. Temperature measures hotness and coldness on scales like Fahrenheit and Celsius. A thunderstorm is a storm with lightning and thunder within a cloud and can include heavy rain and hail.
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.
Humidity
Humidity refers to the amount of water vapor in the air. There are three main types of humidity: absolute, relative, and specific. Absolute humidity is a direct measure of the mass of water in a given volume of air. Relative humidity compares the actual water content of the air to the maximum amount the air can hold at a given temperature. Specific humidity measures the ratio of water vapor to total air mass. Relative humidity is affected by temperature and the amount of water in the air. High humidity can impact climate, plants, animals, human comfort, and more. The most humid areas tend to be near the equator and coastal regions.
Meteorology
Meteorology is the science that studies atmospheric phenomena like weather. Meteorologists use weather stations around the world to collect data on elements like clouds, rain, wind, humidity, and instruments are used to measure these elements. The history of meteorology dates back to ancient times and key developments over centuries included the invention of the barometer, thermometer, and satellites that now allow global weather monitoring.
Climate and weather (teach)
Brief introduction to climate and weather and the differences between them. For elementary school students.
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.
Evaporation
The document discusses evaporation and the factors that affect the rate of evaporation, including temperature, surface area, humidity, and air movement. It explains that evaporation is a cooling process where fast-moving liquid particles escape at the surface and enter the vapor phase, lowering the temperature of the remaining liquid. Condensation is described as the opposite process of evaporation. Examples are provided to illustrate how to calculate the energy required for evaporation and the increase in body temperature if that energy was not removed through sweating during exercise.
Weather Maps and Symbols
Different types of weather maps and whay symbols they use to give us diffrent information about how the weather is on a particular day.
Kinds of Clouds
Clouds
What are clouds?
A cloud is a large collection of very tiny droplets of water or ice crystals. The droplets are so small and light that they can float in the air.
Why do clouds float?
A cloud is made up of liquid water droplets. A cloud forms when air is heated by the sun. As it rises, it slowly cools it reaches the saturation point and water condenses, forming a cloud. As long as the cloud and the air that its made of is warmer than the outside air around it, it floats!
There are 3 main types of clouds:
Cirrus or thin feathery clouds
Stratus or layered clouds
Cumulus or fluffy clouds
Cirrus Clouds
Are the most common of the
high clouds. They are composed of ice and are thin, wispy clouds blown in high winds into long streamers. Cirrus clouds are usually white and predict fair to pleasant weather. By watching the movement of cirrus clouds you can tell from which direction weather is approaching. When you see cirrus clouds, it usually indicates that a change in the weather will occur within 24 hours.
Stratus Clouds
are uniform grayish clouds that often cover the entire sky. They resemble fog that doesn't reach the ground. Light mist or drizzle sometimes falls out of these clouds.
Cumulus Clouds
are white, puffy clouds that look like pieces of floating cotton. Cumulus clouds are often called "fair-weather clouds". The base of each cloud is flat and the top of each cloud has rounded towers. When the top of the cumulus clouds resemble the head of a cauliflower, it is called cumulus congestus or towering cumulus. These clouds grow upward and they can develop into giant cumulonimbus clouds, which are thunderstorm clouds.
The Importance of Clouds
Clouds help regulate Earth's energy balance by reflecting and scattering solar radiation and by absorbing Earth's infrared energy.
Clouds are required for precipitation to occur and, hence are an essential part of the hydrologic cycle.
Clouds indicate what type of atmospheric processes are occurring (e.g., cumulus clouds indicate surface heating and atmospheric turbulence).
Clouds help redistribute extra heat from the equator toward the poles.

Wind
Wind is the moving air masses due to the earth’s unequal surface heating because of its angular tilt.
Wind
Wind is caused by differences in air pressure and is responsible for weather patterns globally. The main drivers of wind include solar heating of the atmosphere creating pressure differences, the Coriolis effect which causes winds to bend, and pressure gradient force pushing air from high to low pressure areas. Global wind systems include the trade winds near the equator, the prevailing westerlies in mid-latitudes, and polar easterlies near the poles. Local winds are also influenced by differences in land and sea temperatures.
Types of Cloud
The document defines and describes the 10 major types of clouds, including cirrus, cirrocumulus, cumulonimbus, altocumulus, altostratus, cumulus, stratus, stratocumulus, cirro, and nimbostratus. Each cloud type is given a brief description of its appearance such as thin and wispy, small and puffy, or tall and fluffy. Latin and Greek roots are also provided to explain the meaning behind parts of cloud names.
Erosion
Erosion is the process by which soil and rock are removed from the Earth's surface by natural processes such as wind or water flow and transported to other locations. There are different types of erosion including wind, water, gravitational, and coastal erosion. Excessive erosion causes problems such as desertification, decreases in agricultural productivity, sedimentation of waterways, and ecological collapse.
Weather and Climate
This document provides information about weather, climate, and climates of the Philippines for a 120 minute lesson in high school earth science. It defines weather and climate, describes factors that influence climate such as latitude, altitude, proximity to bodies of water, and prevailing winds. It also outlines the four climate types in the Philippines and discusses the northeast and southwest monsoon wind systems that influence the country's seasonal rainfall patterns.
Weather patterns
Fronts are boundary surfaces that separate air masses of different densities. Warm fronts occur when warmer air overrides cooler air, causing the warmer air to lift up along the wedge of cold air. This lifting causes clouds and precipitation to form ahead of the surface position of the warm front. As the warm front passes, air temperatures gradually rise and skies typically clear.
Sweat
This document describes an experiment that models how the human body regulates temperature through sweating. The experiment uses clay jugs filled with hot water to represent the body. One jug is covered with a plastic bag while the other is uncovered. Temperature and humidity sensors monitor changes over time. Covering the jug prevents evaporation, causing its temperature to rise more than the uncovered jug. This demonstrates how sweating and evaporation cool the body during fever by increasing heat dissipation. Maintaining this process prevents overheating, though it can lead to dehydration if water is not replaced.
Topic: What is Science
This document discusses key concepts in science. It defines science as a way of learning about the natural world through scientific inquiry and the scientific method. The scientific method involves posing questions, developing hypotheses, testing through controlled experiments, gathering data, and drawing conclusions. A hypothesis is an educated guess that can be tested. Key parts of an experiment are the independent variable, which the scientist can manipulate, and the dependent variable, which changes due to the independent variable. Data provides evidence gained through observation.

Repeating experiments, displaying results clearly, and thoroughly answering the original question are emphasized.
The 4 Seasons
The document summarizes the four seasons - winter, spring, summer, and autumn. For each season it provides examples of activities one can do in that season, typical clothing worn, and holidays or celebrations that occur. Some key details mentioned include skiing and wearing warm clothes in winter, cycling and spring clothes in spring, surfing and summer clothes in summer, and trekking and rain clothes in autumn. Christmas, Easter, holidays, and Halloween are listed as examples of seasonal celebrations.
The 4 Seasons
The document describes the four seasons - winter, spring, summer, and fall. It provides details about the typical weather, celebrations, and clothing for each season. Winter is cold and snowy. Spring brings rain and warmer weather. Summer is hot and sunny. Fall weather cools down and leaves change colors. Each season is also associated with popular holidays and events.
Wave energy
The Pelamis Wave Energy Converter is a technology that uses the motion of ocean waves to generate electricity. It consists of cylindrical sections linked by hinged joints that capture the energy from waves moving the joints. As the joints move with the waves, hydraulic rams and motors drive electrical generators to produce electricity. Several Pelamis devices can be connected together via subsea power cables to transmit electricity to shore. The technology is proposed for use in India to help meet growing electricity demand.
IB Biology Evolution - Earland
Analogous structures are similar in function but different in structure and evolved independently in response to similar environmental pressures. Examples include wings in insects and birds that allow flight through different wing structures, and streamlined bodies of seals and penguins for swimming. Population size and survival are influenced by overpopulation leading to selection for or against individuals. Survivors form the new breeding population, increasing frequencies of advantageous alleles and evolving characteristics over time. Genetic variation within a species arises from meiosis creating new chromosome combinations, random fertilization increasing combinations further, and crossover during meiosis increasing variations additionally.
A5: Food Science (Additives)
Food additives serve several important functions in food processing and preparation. Sweeteners add sweetness and bulk while lowering the freezing point of ice cream. Thickeners change texture and consistency and help maintain structure. Preservatives prevent growth of microbes like fungi and molds to extend shelf life. Antioxidants slow oxidation and prevent rancidity. Emulsifiers allow oil and water to mix without separating. Common types and their uses in foods are described.
Layers of the Earth
The document describes the four main layers that make up the Earth - the crust, mantle, outer core, and inner core. The crust is the outermost layer, upon which we live, and is broken into tectonic plates. Below the crust is the mantle, which is divided into the upper and lower mantle. The lower mantle is very thick and contains molten rock that moves in convection currents. Deepest inside the Earth is the core, with a liquid outer core that generates the Earth's magnetic field and a solid inner core under intense heat and pressure.
Gravity for Elementary and Middle students (Teach)
Gravity is a force that pulls all objects towards one another. The more mass an object has, the stronger its gravitational pull. While it appears lighter objects fall slower on Earth, this is due to air resistance, not differences in mass - in a vacuum all objects fall at the same rate. The amount of gravity and weight experienced varies on different planets depending on their mass.
Groundwater
Groundwater and surface water are interconnected through the hydrologic cycle and comprise our water resources. However, extraction and pollution are threatening these resources. Over-pumping of aquifers like the High Plains Aquifer has caused water tables to drop significantly. The Middle East is also over-pumping groundwater, causing saltwater intrusion. Once polluted, groundwater remains contaminated for a long time since it flows more slowly than surface water. Increased water demand and improper management are reducing available fresh water supplies globally. Sustainable practices are needed to protect this vital resource for the future.
Topic 2 - The Nature of Science
This topic reviews the nature of science including the six step scientific method, scientific theories and laws.
Ground water hydrology
This document discusses groundwater hydrology. It defines groundwater and describes the zones of saturation and aeration below the surface. It then explains various hydrologic concepts like the water table, soil water, and capillary fringe. It also defines different zones within an aquifer like unconfined and confined, and describes their properties. Key concepts like porosity, permeability, transmissibility, and Darcy's law are summarized. Finally, it briefly discusses Dupuit's assumptions and pumping tests.
acid rain ppt
this ppt tell u what is acid rain, how is it caused, the heavy impact, the preventions and the glossary....hope u'll like it
groundwater
Groundwater is water located beneath the Earth's surface that infiltrates through soil and fills pores and cracks in rock. It is found within two main zones - the unsaturated zone above the water table where pores contain both air and water, and the saturated zone below where all pores are filled with water. Groundwater is recharged from precipitation and flows through the ground via gravity and pressure differences, discharging through springs, streams or being extracted by wells. Contamination can enter groundwater from various sources like spills, waste disposal or fertilizers, spreading through the subsurface over time. Treatment methods aim to filter out contaminants but remediating polluted groundwater is challenging.

12 seven characteristics of living organism.
Living things have seven distinguishing life processes: nutrition, respiration, movement, growth, excretion, reproduction, and irritability. Animals and plants exhibit these processes in different ways. Animals must obtain food from other living things, while plants can make their own food through photosynthesis. Muscles enable animal movement and respiration releases energy from food in both animals and plants. Waste products are excreted to remove toxins from the body.
Classroom rules class 1
This document outlines 7 classroom rules: students must obtain permission before talking or leaving their seat; homework is due on assigned dates; students should come prepared with materials; name and date should be written on work; questions should be read carefully before answering; and interrupting is not allowed.
Solar system g6
Gravity and inertia work together to keep planets in orbit around the Sun. Gravity provides an attractive force between all massive objects like the Sun and planets. Inertia is the tendency of a moving object to stay in motion, which causes planets to travel in curved paths rather than flying off in straight lines. The balance between gravity pulling planets toward the Sun and inertia allowing them to travel in circles results in stable orbits that have allowed planets to revolve around the Sun for billions of years.
Astronomy lesson 1
The document discusses different types of telescopes used in astronomy. It describes refracting telescopes which use lenses and reflecting telescopes which use mirrors. Most large telescopes found in observatories are reflecting telescopes because it is easier to build large mirrors that can collect more light. The document also discusses other types of telescopes like infrared telescopes that can observe invisible light beyond the visible spectrum.
Moon g6 2
The document summarizes key features of the lunar landscape as observed from Earth. It describes light and dark colored areas on the moon's surface, including craters formed by impacts, large flat dark areas called maria formed by ancient lava flows, mountains around the edges of maria, and older highlands near the lunar poles with more craters. It also discusses lunar phases caused by the changing orientation of the moon as it orbits Earth, solar and lunar eclipses, and tides caused by the gravitational pull of the moon and sun.
Unit 1 lesson 1
This document outlines some of the rules students should follow at school. It explains that rules help keep students safe and happy, and that teachers set the classroom rules to follow, such as playing nicely on the playground, following the line leader, and walking quietly in the hallways.
Project detai;s
Each student group chose a planet to explore for a project presented as a PowerPoint with videos and animations. The presentation must include the length of the planet's day and year, its order by distance from the sun and size, number of moons, structure and features, and recent discoveries.
Asteroids ,comets and meteors
Between Mars and Jupiter lies the asteroid belt, home to rocky asteroids that orbit the sun. Comets are balls of ice and rocks that develop long tails as they near the sun due to warming and gas release. Meteoroids are small objects that orbit the sun and occasionally collide with celestial bodies like the moon, and meteors are meteoroids that burn up in a planet's atmosphere in a bright streak. Those that reach a planet's surface are called meteorites.
3rd tri g6 project
This trimester, students have been learning about outer space, stars, moons and planets. They will be divided into groups to explore different planets in the solar system, with each group assigned certain planets to research and report on, as will be announced on the class wiki tomorrow along with due dates for each task.
Solar system 1
Gravity and inertia work together to keep planets in orbit around the Sun. Gravity provides an attractive force based on the masses of the planet and Sun that curves the planet's path. Inertia causes objects to travel in a straight line, but gravity pulls planets into an elliptical orbit rather than flying off into space in a straight line. Ancient models incorrectly thought Earth was the center, but it is now known that planets revolve around the Sun.
Tides
The regular rise and fall of water levels along a shore is caused by tides. Tides are primarily caused by the gravitational pull of the moon on Earth's oceans, which causes the water to bulge on the side facing the moon. Sometimes when the sun, moon, and Earth are aligned, the combined gravitational pull results in especially strong spring tides with higher high tides and lower low tides, while neap tides with weaker gravitational pull result in smaller differences between high and low tides.
Solar eclipse
An eclipse occurs when one celestial body blocks light from another body. There are two types of eclipses: solar and lunar. A solar eclipse happens during a new moon when the moon passes between the sun and earth, casting its shadow on earth. Some places experience the sun being fully covered while others only see a partial covering.
Phases of the moon
The phases of the moon are caused by the changing position of the Earth, Moon, and Sun, with half the Moon's surface always reflecting sunlight. As seen from Earth, the amount of the Moon's lit surface changes over a cycle from new moon to full moon and back again, known as waxing and waning, with the main phases being new, crescent, quarter, and full moons.
Lunar landscape All
The document summarizes key features of the lunar landscape. It describes craters as bowl-shaped depressions formed by impacts from space objects. Maria are large, flat, dark areas on the moon formed when huge impacts caused lava flows that cooled into smooth, dark surfaces. Mountains formed around the edges of maria from the same impacts. Highlands near the lunar poles have more craters, indicating they are older landscapes. Some deep valleys may contain small amounts of ice.
Lunar landscape
The moon's surface has light and dark colored areas visible from telescopes. Large craters formed from impacts with space objects, and there are also large, flat dark areas called maria that appear smooth. The maria were formed when huge impacts caused lava to fill the impacted areas, and after cooling the lava gave the maria their dark, smooth appearance, though early observers mistakenly thought they were seas.
Revolution
Images taken from Earth of other planets have less sharpness and detail than those taken from space due to Earth's atmosphere interfering with photo quality, while images from space are not impacted by an atmosphere. The Earth revolves around the sun, resulting in the four seasons due to changes in the tilt of the Earth and the location of the sun throughout the year.
Shadows
The document discusses the International Date Line and how traveling west across it would change the date. It also talks about how space probes send images and data back to Earth for scientists to study, and how artificial satellites are sometimes launched into space by astronauts on the space shuttle before the astronauts return to Earth on the shuttle.
Standard time zone
Standard time zones were established in 1884 with 24 zones around the world representing one hour each. Places within the same time zone use the same time, and time changes by one hour when traveling east or west between zones. If it is 8:00 pm in Denver, Colorado (Mountain Time), the time in Atlanta, Georgia (Eastern Time) would be 9:00 pm since Atlanta is one time zone east of Denver. Traveling west across the International Date Line would result in the date changing.
Rotation and day and night
The Earth has two types of movements: rotation around its axis, which takes 24 hours and results in the cycle of day and night as different parts of the Earth face the sun, and rotation around the sun in its orbit. The Earth's axis is an imaginary line passing through the north and south poles. When a part of the Earth faces the sun it is daytime, and when a part faces away it is night.
Refracting and reflecting telescope
Refracting telescopes use lenses to gather and focus light, while reflecting telescopes use mirrors. Most large telescopes, like those found in observatories, are reflecting telescopes because it is easier to build large mirrors that gather more light. Invisible light telescopes can detect wavelengths beyond the visible spectrum, allowing astronomers to study objects that cannot be observed with visible light alone, such as using infrared telescopes to gather heat signatures.

Humidity
- 2. Humidity It is the amount of water vapor in the air . The higher the temperature the more water vapor it can hold Warm air can absorb much more water vapor than cold air
- 3. Relative Humidity The amount of water vapor in the air compared to the total amount that air can hold at that temperature . When water can’t hold water vapor anymore the relative humidity is 100%
- 4. • When the air is saturated or filled with water vapor ,any additional water vapor will condenses in to a liquid ….This temperature is called “Dew point “
