rainfall

Definition

Rain is water that falls from the sky. It is formed when water vapour in the air cools and condenses into tiny droplets. These droplets then clump together to form clouds. When the clouds become too heavy, the water droplets fall to the ground as rain.

Rain is important for plants and animals. Plants need rain to grow, and animals need water to drink. Rain also helps to clean the air and water, and it can help to prevent fires.
