Water Cycle

Front

What is the Water Cycle?

Back

The continual movement of water among Earth's atmosphere, oceans, and land surface through evaporation, condensation, and precipitation.

Front

What is Evaporation?

Back

The change of a substance from a liquid to a gas.

Front

What is Condensation?

Back

The process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is Precipitation?

Back

Any form of water, liquid or solid, that falls from the atmosphere to the Earth's surface, such as rain, snow, sleet, or hail.

Front

What is Transpiration?

Back

The process by which water is absorbed by plants and then released as water vapor into the atmosphere.

Front

What is Sublimation?

Back

The process in which a solid changes directly into a gas without becoming a liquid first.

Front

How does solar energy affect the water cycle?

Back

Solar energy drives the water cycle by providing the heat necessary for evaporation.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed by condensation and are essential for precipitation, returning water to the Earth's surface.

Front

What is the difference between evaporation and transpiration?

Back

Evaporation is the process of water turning into vapor from surfaces like oceans, while transpiration is the release of water vapor from plants.

Front

What is the significance of the water cycle for ecosystems?

Back

The water cycle is crucial for maintaining ecosystems, providing fresh water for plants, animals, and humans.
