Natural cycle for life.
The water cycle: Water is essential to life.
None of us can live without it for more than a few days. The water cycle distributes fresh, clean water around the planet. It invovles three stages. (1) Solar power lifts water into the atmosphere by evaporarion. (2) Condenstaion of this purified water produces clouds. (3) Clouds, in turn, from rain, hail, sleet, or snow, which falls to the ground, ready to evaporate again, thus completing the cycle. How much water is recycled annually? According to estimates, enough to cover the earth's surface informly to adepth of more than two and a half feet.
