The Water Cycle Water is essential for life. It is made of two molecules of hydrogen and one of oxygen. Water is recycled naturally. The sun heats the water in lakes, streams, oceans and on the ground, changing it into water vapour.
Plant leaves give off water vapour too.
These tiny drops become clouds. The water vapour condenses into liquid and becomes rain or sometimes freezes to form snow and hail which then falls to the ground. The sun heats the water and so the cycle repeats. Draw your own water wheel. Back to the Giant Flower Islands.
