What is the water cycle?

Back

Front

What is evaporation?

Back

Evaporation is the process by which water changes from a liquid to a gas or vapor.

Front

What is condensation?

Back

Condensation is the process by which water vapor cools and changes back into liquid water, forming clouds.

Front

What is precipitation?

Back

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