Precipitation is any kind of water that falls from clouds. Rain is a form of precipitation as well as snow, hail, and sleet.
<u><em>I will provide two examples of precipitation below.</em></u>
Rain is a liquid water that falls from clouds. Tiny drops of water stick to dust in the air and this causes the water and dust to form clouds. The water drops join together and get bigger and eventually fall.
Snow is a form of precipitation. It is a solid water called crystals. Snow falls from storm clouds and the air temperature must be freezing for snow to fall. Although snow looks white, it's really clear like water.
