What is the water cycle?
the 3 forms of water as they change their physical states
the movement of water on, above, or below the surface of the Earth
when plants perform photosynthesis
when clouds form
What is condensation?
The part of the water cycle when the sun heats up water, turning it from a liquid into water vapor. It rises from the ground into the air.
