The water cycle is the path that all water follows as it moves around our planet. Heat
from the sun causes water to evaporate from oceans, lakes and streams. Evaporation occurs
when water on Earth's surface turns into water vapor in our atmosphere. Warm water rises
through Earth's atmosphere. As the water vapor rises higher and higher, the cool air of the
atmosphere causes the water vapor to turn back into water creating clouds. This process is called
condensation. When a cloud becomes full of liquid water, it falls from the sky as rain - also known
as precipitation. Rain then fill the lakes and streams, and the process starts all over again.
