Explanation:

Precipitation -

Precipitation is the process of condensation of the atmospheric water vapor that falls by gravity .

The forms of precipitation are - rain , sleet , snow, hail , drizzle and graupel .

The process of precipitation occurs when , the atmosphere gets saturated with water vapor , and then the water gets condenses and precipitates .
