Rain is a type of fluid, which attracts gravity from the sky to the surface of the earth. Water vapor condenses in the atmosphere of the Earth causing clouds. If these drops are heavy enough to fall on the earth's surface - that is why they say rain. Rainwater is a major source of rain water in most parts of the world. Rainwater is needed to keep people's minds fresh, to keep hydro power projects active and to keep irrigation system active, to save the diverse biosphere. Although not all types of rain reach the surface. Some rainy points dry when reading through the dry air. This feature known in Bharganam is seen in dry desert areas.
