World water cycle


This picture shows the cycle of water

The Sun heats the water in rivers, lakes, seas, and oceans. It evaporates, and water vapour is formed. It rises up in the atmosphere. It cools and condenses, and clouds are formed. When the water droplets became heavy, it rains or snows. Water goes into the soil or to the rivers, lakes and oceans again. The cycle repeats itself.
