Condensation is the part of the water cycle in which

• the sun heats water, turning it from a liquid into water vapor. It rises from the ground into the air.

• water vapor in the air gets colder and turns back into a liquid and forms clouds.

• clouds get heavy and can no longer hold the liquid water so it falls to Earth as rain, snow, sleet, or hail.

• water leaves plants through the stomata in the underside of their leaves.
