Precipitation is the (liquid and solid) water droplets that fall from clouds and reach the surface. The falling liquid droplets include drizzle and rain, the solid water droplets include snow and hail. Precipitation forms when the growing cloud droplets become so big that they fall under their own weight.

Precipitation is a key factor in the development of plants and hence agriculture.

Deserts are characterised by extremely low precipitation.
