Water and energy are transferred throughout the hydrosphere, lithosphere, and atmosphere during the water cycle.

The amount of water on Earth remains constant, but it continuously changes forms as energy from the Sun drives the cycle.

Movement of Water During the Water Cycle
The water cycle describes the continuous movement of water on, above, and below the surface of the Earth.
![Page 5: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/5.jpg)
This movement of water in the cycle can have a great influence on weather patterns.
![Page 6: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/6.jpg)
There is much more water being stored at any given time than is moving through the cycle.
![Page 7: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/7.jpg)
Water may be stored for a short time as water vapor in the atmosphere, for days or weeks in a lake, or for thousands of years in a polar ice cap.
![Page 8: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/8.jpg)
However, most of the Earth's water is stored in the oceans.
The water cycle is a cycle with no beginning or end.

Condensation is the changing of gas to a liquid (water vapor to water) and is crucial for the formation of clouds.
![Page 11: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/11.jpg)
Clouds form in the atmosphere when air containing water vapor rises and cools.
Water vapor can be present in the air even when clouds are not visible.
![Page 12: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/12.jpg)
Clouds become visible when water particles combine with each other around tiny particles of dust to form water droplets.
![Page 13: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/13.jpg)
Water returns to the Earth as precipitation.
Rain, freezing rain, sleet, snow, and hail are all forms of precipitation.
![Page 14: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/14.jpg)
Precipitation is the product of water vapor in the air condensing to form drops heavy enough to fall to the Earth's surface.
![Page 15: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/15.jpg)
During infiltration water fills the porous spaces in the rock and soil that makes up the lithosphere.
This is one of the main sources of groundwater.
![Page 16: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/16.jpg)
Surface runoff occurs when no more water can be absorbed into the ground and gravity pulls it downhill until it joins a body of surface water, such as a river, stream, or lake.
![Page 17: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/17.jpg)
Some of this surface water may seep downward and become groundwater.
The rest of the water in a flowing water body, such as a river, eventually empties into the ocean.
![Page 18: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/18.jpg)
Evaporation takes place largely from the oceans.
It often happens as a result of heat produced by the radiant energy from the Sun–liquid water is heated until it turns to a gas (water vapor) and is released into the atmosphere.
![Page 19: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/19.jpg)
Transpiration is similar to evaporation in that it is the process by which water is carried through plants, from roots to leaves, where it changes to water vapor and is released to the atmosphere.
![Page 20: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/20.jpg)
Sublimation is the changing of water from a solid directly to a gas with no intermediate liquid stage.
The opposite of sublimation is deposition, when water vapor changes directly to a solid.
Snowflakes and frost are examples of deposition.

Watershed Systems
A watershed is a region of land where rain or snow (along with sediments and dissolved materials) drains downhill into a specified body of water, such as a river, lake, sea, ocean or wetland.
![Page 22: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/22.jpg)
Watershed Structure
The area of land where water is drained downhill into a body of water is known as a drainage basin, or watershed.
The components of a watershed include lakes, streams, rivers, wetlands, and groundwater.
![Page 23: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/23.jpg)
![Page 24: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/24.jpg)
When precipitation falls onto land surfaces, it can either be soaked into the ground or become runoff, which is surface water that travels downhill and drains into streams and rivers.
![Page 25: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/25.jpg)
A watershed, or drainage basin, is the area of land where surface water is drained downhill into a body of water.
Water can flow among all of the components of a watershed, including between groundwater and surface features like lakes, streams, rivers, oceans and wetlands.
![Page 26: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/26.jpg)
Watersheds are separated from adjacent watersheds by a water divide, which is the high ground between two watersheds.
At the point of the divide, water that falls on one side of the divide will drain into one watershed, while water that falls on the other side will drain into another.
![Page 27: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/27.jpg)
A divide is often a geographical feature, such as a ridge, hill, or mountain.
Often, the body of water into which a watershed drains is a river basin.
Eventually, all rivers, and therefore all watersheds, drain into the ocean.

Convection in Atmosphere
Convection is the mixing motion of liquids and gases that are different temperatures.
Convection is caused by the fact that warmer liquids and gases are less dense.
![Page 29: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/29.jpg)
Convection Occurs in Fluids
The word fluid can refer to both liquids and gases—anything that can flow.
Warm fluids rise, while cool fluids sink.
Any source of heat, such as the Sun, will tend to create a convection current in the fluids it is heating.
![Page 30: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/30.jpg)
![Page 31: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/31.jpg)
Convection in the Atmosphere — Wind
The Sun is the ultimate driving force for weather and climate patterns on Earth.
Due to Earth's shape, position, and movement through space, the Sun heats Earth's atmosphere unevenly.
![Page 32: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/32.jpg)
Only half of Earth receives sunlight at one time.
In addition, solar rays are more concentrated at the equator than at areas of higher latitude.
![Page 33: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/33.jpg)
Thus, some parts of the atmosphere become warmer than other parts.
Warm air has a lower pressure than cool air.
![Page 34: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/34.jpg)
Warm air molecules are spread out; therefore, they do not place a lot of pressure on the area beneath.
Cool air molecules gathered close together place greater pressure on the area beneath.
![Page 35: The Water Cycle Mr. Lerchenfeldt](https://reader036.vdocuments.net/reader036/viewer/2022062302/5a4d1b8f7f8b9ab0599c0a66/html5/thumbnails/35.jpg)
To maintain a balance, air masses flow from areas of high pressure to areas of low pressure.
It is during this process that wind is produced.
