Moisture that is heavy enough to fall back to Earth is called precipitation.

Here's a breakdown of the different types of precipitation:

* Rain: Liquid water falling from clouds.

* Snow: Frozen precipitation in the form of ice crystals.

* Sleet: Frozen raindrops that partially melt and then refreeze as they fall.

* Hail: Large, round pieces of ice that form in thunderstorms.

* Drizzle: Very light rain, often in the form of tiny droplets.

* Freezing rain: Rain that freezes upon contact with surfaces, creating a sheet of ice.
