Formation of Rain


How rain is formed?

               Rain is useful to all creatures, plants and trees. It is formed through a number of stages. Earth surface is heated. Water is always evaporated by heat. Heat of the sun rays evaporate water from the surface of seas and streams. Water vapour is lighter than air and so it rises high in the sky. It becomes cooler as it goes higher. The cool water vapour condenses and floats in the sky in form of clouds. Going upwards the clouds transform into water drops.

The water drops become so heavy that they cannot float. So they fall on earth as rain.
