The definition of precipitation is any form of water - liquid or solid - falling from the sky.
It includes rain, sleet, snow, hail and drizzle plus a few less common ones such as ice pellets, diamond dust and freezing rain. Precipitation forms within clouds in a couple of ways: either water droplets or ice crystals colliding together, or enlarging as water condenses out of the air into a droplet.
What we see on the ground can vary a lot more largely because of the air temperature, but sometimes where the air originated, for example blood rain. Find out more about the different types of precipitation below.
