Precipitation is the term given to moisture that falls from the air to the ground. Precipitation can be snow, hail, sleet, drizzle, fog, mist and rain.

The water cycle drives the water from the oceans/seas on-shore where it falls as

precipitation and then flows via rivers back in to the sea.

form and precipitation occurs.- The drier air descends and heats up.
