Snow
From Wikipedia, a free encyclopedia written in simple English for easy reading.
Snow is the frozen ice cristals of rain. when the clouds are full they give out the rain but in cold weathers the clouds freeze so it gives out ice crystals. Often, snow freezes into shapes called "snowflakes".
The origin of the word stems from Old English snaw, akin to German schnee. It consists of particles of water vapour which when frozen in upper regions of the air (see atmosphere, biosphere, climate, meterology, weather) fall to earth as soft, white, crystalline flakes (snowflakes, fernlike ice crystals, a cluster of these).
At a given temperature (called the freezing point, 0° Centigrade, 32° Fahrenheit), snow uses to melt away and vanish. The process when snow/ice changes directly into water vapour without melting is called sublimation. The opposite process is called deposition.
It is a prerequisite for winter sport activities like skiing and sledding (slalom).
