precipitation Scientific  

/ prĭ-sĭp′ĭ-tā′shən /

1. 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.

2. 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.

Etymology

Origin of precipitation

First recorded in 1425–75; late Middle English, from Latin praecipitātiōn-, stem of praecipitātiō “a casting down headlong,” equivalent to praecipitāt(us) “cast down headlong” (past participle of praecipitāre see precipitate) + -iō -ion

Explanation

Precipitation is rain, snow, sleet, or hail — any kind of weather condition where something's falling from the sky. Precipitation has to do with things falling down, and not just from the sky. It's also what happens in chemical reactions when a solid settles to the bottom of a solution. If you have hard water where you live, you might find lime deposits — a flaky white crust — on your faucets and showerhead. That's caused by precipitation of the minerals in the water. The minerals settle out — they precipitate — and clog the pipes.
