Snow is a type of precipitation in atmosphere in the form of crystalline water ice. Snow only occurs when the air temperature is at or around the freezing point of water.

About Snow

Snow is precipitation in the form of flakes of crystalline water ice that fall from clouds. Since snow is composed of small ice particles, it is a granular material. It has an open and therefore soft structure, unless subjected to external pressure. Snowflakes come in a variety of sizes and shapes. Types that fall in the form of a ball due to melting and refreezing, rather than a flake, are known as hail, ice pellets or snow grains.
