What happens during evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas, usually when it is heated.

What is runoff?

Back

Runoff is water that flows over the ground and returns to rivers, lakes, and oceans.

Front

What are clouds made of?

Back

Clouds are made of tiny water droplets or ice crystals that form when water vapor condenses.

Front

How does temperature affect evaporation?

Back

Water evaporates faster on hot days because heat gives water molecules more energy to escape into the air.

Front

What is the role of the sun in the water cycle?

Back

The sun provides the heat needed for evaporation to occur, driving the water cycle.

Front

What is an example of solid precipitation?

Back

Snow is an example of solid precipitation.

Front

How long can water stay in the water cycle?

Back

Water can stay in the water cycle for millions of years.
