How does
rain come
Rain is the primary source of fresh
water for most areas of the world, providing suitable conditions for diverse
ecosystems, as well as water for hydroelectric power plants and crop
irrigation.
The phenomenon 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
vapor rises into 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 precipitation which can be in the form of rain or snow.
However, not all rain reaches the
surface. Some evaporates while falling through dry air. This is called virga, a
phenomenon which is often seen in hot, dry desert regions.
