Water Cycle

Water is life. Every living thing depends on water: people, animals and plants. The earth has a limited amount of water, which keeps going around and around in the water cycle. Water evaporates from the surface of the earth, rises and cools, and falls again to the surface as rain. The water falling on land collects in river and lakes, soil and porous layers of rock, and much of it flows back into the ocean.
