What is the main source of energy for the water cycle?

Back

The sun is the main source of energy that drives the water cycle.

Front

What is transpiration?

Back

Transpiration is the process where plants release water vapor into the air from their leaves.

Front

What role do clouds play in the water cycle?

Back

Clouds are formed from condensed water vapor and are important for precipitation.
