'''Precipitation''', in [[meteorology]], is any type of [[water]] that falls from the sky as part of the [[weather]]. This includes [[snow]], [[rain]], [[sleet]], [[freezing rain]] and [[hail]]. Precipitation is a major part of the [[waterhydrologic cycle]], and is responsible for depositing most of the [[fresh water]] on the planet. Precipitation is generated in [[cloud]]s, which reach a point of saturation; at this point larger and larger droplets (or pieces of [[ice]]) form, which then fall to the earth under [[gravity]]. It is possible to 'seed' clouds to induce precipitation by releasing a fine dust or appropriate chemical (commonly [[silver nitrate]]) into a cloud, encouraging droplets to form, and increasing the probability of precipitation.

In [[chemistry]], '''precipitation''' is the condensation of a [[solid]] from a [[solution]]. This occurs when the solution is [[saturated]], whereupon the solid forms from the solute phase, and usually sinks to the bottom of the solution.
