Rain is the primary source of fresh water for most areas of the world, providing suitable condition for diverse ecosystems, as well as water for hydroelectric power plants and crop irigation.
The phonomenon of rain is actually a water circle. The concept of the water cycle involves the sun heating the Earth’s surface water and causing the surface water to evaporate. The water vapour rises in to the earth’s atmosphere. The water in the atmosphere cools and condenses into liquid droplets. The droplets grow until they are heavy and fall to the earth as precipilation which ca be in the form of rain or snow.
However, not all rain reaches the surface area. Some evaporates while falling throught dry air. This is called virga, a phonemenom which often seen is hot, dry desert region.
