What is condensation?

• The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor or steam.

• The part of the water cycle when clouds get heavy and can no longer hold the liquid water, which falls to Earth as rain, snow, sleet, or hail

• The part of the water cycle when the water vapor in the air gets cold. The water turns back into a liquid and forms clouds

• The part of the water cycle where water runs off a slope like a mountain, leading it back to the ocean
