Water moves from the Earths surface to the Atmosphere, then it moves back to the surface. Water changes states forms as it moves.How does water changes?

Evaporation

During EvaporationWater turns from a liquid to a gas.

Water moves from rivers and lakes into the atmosphere in the form of water vapor.


Liquid to a Gas


Condensationcondensation is the process of gas cooling to form a liquid


So what is Condensation?Condensation is a process, a changeIts the cooling process that changes gas into a liquidIt is the opposite of evaporation.

The Water Cycle

Water never leaves the Earth. It is constantly being cycled through the atmosphere, ocean, and land. This process, known as the water cycle, is driven by energy from the sun. The water cycle is important to the existence of life on our planet.

EvaporationHeat energy from the sun causes water in puddles, streams, rivers, seas or lakes to change from a liquid to a water vapor. This is called evaporation. The vapor rises into the air and collects.

Evaporation

The conversion of water from a liquid to a gas

Solar energy drives evaporation of water from the ocean. The evaporated water changes from a liquid form into water vapor a gaseous form.

14Evaporation is a critical component of the water cycle, which is responsible for clouds and rain. Solar energy drives evaporation of water from oceans, lakes, moisture in the soil, and other sources of water.

QUESTION: How does evaporation relate to weather?ANSWER: Evaporation is responsible for clouds and rain.

CondensationWater vapor collects in the sky. As the it cools the water vapor condenses into water drops. Clouds are formed by condensation.

CondensationThe transformation of water vapor back into liquid water by cooling

Evaporated water is warmed and rises into the air where it eventually cools and condenses to form clouds.

16The water seen on the outside of a cold glass on a hot day is condensation. Condensation is the changing of water from a gaseous state back to a liquid state in the form of clouds.

QUESTION: How is condensation related to weather?ANSWER: Condensation forms clouds, which can produce rain, hail, or snow.

PrecipitationWater falls to the earth from clouds. Mainly as rain, but sometimes as snow, sleet and hail. This is called precipitation.

PrecipitationRain, hail, or snow falling from the clouds due to the condensation of water

With enough condensed water, you get rain!

When clouds become very heavy with condensed water, the water is released in the form of rain, hail, or snow.

18Precipitation is a major component of weather and of the water cycle. Precipitation is responsible for depositing most of the fresh water on the planet.

CollectionThe collection of precipitation into rivers, lakes, and oceans.

This completes the water cycle!

19The ocean is an integral part of the water cycle and is connected to all of the earths water reservoirs via evaporation and precipitation processes.

When rain falls on the land, some of the water is absorbed into the ground forming pockets of water called groundwater. Most groundwater eventually returns to the ocean. Other precipitation runs directly into streams or rivers. Water that collects in rivers, streams, and oceans is called runoff.

Groups of water vapor together form the clouds. There are three types of clouds: 1) Cumulus. 2) Stratus. 3) Cirrus.Clouds

-Puffy & white clouds that look like cotton balls.-They often have a flat bottom.-This kind of clouds produces precipitation.

(1) Cumulus clouds

-Clouds form in layers.-The layers look like sheets or blankets.-They are often the lowest clouds in the sky.-Fog is a stratus cloud.- Stratus clouds can form precipitation.

(2) Stratus clouds

-Clouds look thin, wispy or feathery.-They are made of tiny bits of ice.-Cirrus clouds are usually found very high in the sky(3) Cirrus clouds

PRECIPITATION Hail Rain Sleet Snow

It's the liquid form of the rain. Rain

Sometimes rain falls from clouds as liquid but freezes along the way.-The rain turns into flakes of ice.-This type of rain is sleet.

Sleet

It is made of ice too.-The ice chunks are much larger than sleet.-They are formed inside the tall clouds of thunderstorm.-Some are the size of peas, some are bigger than baseballs.

Hail

When water vapour reaches a temperature below 0C, it freezes into snow.-Bits of snow collect into a cloud, when they get too heavy, they fall as snow. Snow
