Rain

Rain is a kind of precipitation. Precipitation is any kind of water that falls from clouds in the sky, like rain, hail, sleet and snow. It is measured by a rain gauge. Rain is part of the water cycle.

Clouds will often absorb smoke to create rain, commonly referred to as "nature's laundry" due to this process.

Some places have frequent rain. This makes rainforests. Some have little rain. This makes deserts.

A rainstorm is a sudden heavy fall of rain. It may cause flash floods in valleys. Heavy rain for a long time may make floods that destroy houses and drown people. Also, landslides may happen.
