In an aqueous solution, precipitation is the "sedimentation of a solid material (a precipitate) from a liquid solution". [ 1 ] [ 2 ] The solid formed is called the precipitate . [ 3 ] In case of an inorganic chemical reaction leading to precipitation, the chemical reagent causing the solid to form is called the precipitant .
On the leeward side of mountains, desert climates can exist due to the dry air caused by compressional heating. Most precipitation occurs within the tropics and is caused by convection. [3] Precipitation is a major component of the water cycle, and is responsible for depositing most of the fresh water on the planet.
Typical precipitation types associated with a warm front advancing over frigid air Precipitation in the form of a sunshower. In meteorology, the different types of precipitation often include the character, formation, or phase of the precipitation which is falling to ground level. There are three distinct ways that precipitation can occur.
Colorado ski instructor Russ Scholl created the whimsical and funny table to describe and define 133 different kinds of snow.
Ice pellets (Canadian English [1]) or sleet (American English) is a form of precipitation consisting of small, hard, translucent balls of ice. Ice pellets are different from graupel ("soft hail"), which is made of frosty white opaque rime, and from a mixture of rain and snow, which is a slushy liquid or semisolid.
The term precipitation is normally reserved for describing a phase change from a colloid dispersion to a solid (precipitate) when it is subjected to a perturbation. [19] Aggregation causes sedimentation or creaming, therefore the colloid is unstable: if either of these processes occur the colloid will no longer be a suspension.
Cementation (geology) – Process of chemical precipitation bonding sedimentary grains; Cross-bedding – Sedimentary rock strata at differing angles; Drift (geology) – Material of glacial origin; Flocculation – Process by which colloidal particles come out of suspension to precipitate as floc or flake
Rain and snow mixed (American English) or sleet (Commonwealth English) is precipitation composed of a mixture of rain and partially melted snow.Unlike ice pellets, which are hard, and freezing rain, which is fluid until striking an object where it fully freezes, this precipitation is soft and translucent, but it contains some traces of ice crystals from partially fused snowflakes, also called ...
