Precipitation happens when rain, snow, or hail falls to the earths surface
How rain is formed
Rain happens when water vapour turns into rain and it fall down from the cloud, because the earths surface is warm
How snow is formed
Snow forms when water vapour in the atmosphere cools and condenses into ice crystals, these form as snow flakes and fall onto the cool surface of the earth.
How hail is formed
When the water goes higher the water freezes and goes to the storm cloud. As it falls it is cold ice around the size of a golf ball, it hits the ground falling as hard ice
