Snow is precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes.

Snow is commonly formed when water vapor undergoes deposition high in the atmosphere at a temperature of less than 0°C (32°F), and then falls to the ground.

Snow is used as a thermal insulator conserving the heat of the Earth and protecting crops from the freezing weather.
