• In meteorology, precipitation is rain, snow and other material falling from the sky.
• In chemistry, precipitation is the condensation of a solid from a solution during a chemical reaction.
• In geology, precipitation is the sum of runoff, infiltration, and evapotranspiration.

• All liquid or solid phase aqueous particles that originate in the atmosphere and fall to the earth's surface.
• The amount, usually expressed in millimeters or inches of liquid water depth, of the water substance that has fallen at a given point over a specified period of time. As this is usually measured in a fixed rain gauge, small amounts of dew, frost, rime, etc., may be included in the total. The more common term rainfall is also used in this total sense to include not only amounts of rain, but also the water equivalents of frozen precipitation. For obvious reasons, precipitation is the preferred general term. [1]
