According to the provided context, precipitation is the release of moisture that may take place in liquid or solid forms. The text explicitly identifies Rainfall (precipitation in the form of water) and Snowfall (precipitation as fine flakes of snow when temperature is lower than 0°C). It further mentions that besides rain and snow, other forms of precipitation are Sleet and Hail. Since the question asks for three types, Rainfall and Snowfall are the primary forms listed, and Hail is selected as the third distinct type described in detail in the text (formed of small rounded solid pieces of ice). Note that the text separately lists 'Types of Rainfall' (Convectional, Orographic, Cyclonic), which refers to the origin of rain specifically, not the general types of precipitation.
