Word Origin and History for precipitation
n.
late 15c., "a casting down" (of the evil angels from heaven), also, in alchemy "separation of a solid substance from a solution," from Middle French precipitation (15c.) and directly from Latin praecipitationem (nominative praecipitatio) "act or fact of falling headlong, haste," noun of action from past participle stem of praecipitare "fall, be hasty," from praeceps "steep" (see precipice).

(prĭ-sĭp′ĭ-tā′shən)- The process of separating a substance from a solution as a solid.
precipitation
- A form of water, such as rain, snow, or sleet, that condenses from the atmosphere, becomes too heavy to remain suspended, and falls to the Earth's surface. Different atmospheric conditions are responsible for the different forms of precipitation.
- The process by which a substance is separated out of a solution as a solid. Precipitation occurs either by the action of gravity or through a chemical reaction that forms an insoluble compound out of two or more soluble compounds.
precipitation
In meteorology, the fall of water, ice, or snow deposited on the surface of the Earth from the atmosphere. In chemistry, a chemical reaction in a solution in which a solid material is formed and subsequently falls, as a precipitate, to the bottom of the container.
