Snow

Snow is a type of precipitation in the form of crystalline water ice, consisting of a multitude of snowflakes that fall from clouds. It forms when water vapor in the atmosphere freezes into ice crystals before falling to the ground. Snowflakes can take on a variety of shapes and sizes, and the conditions in the atmosphere determine these characteristics.

Formation of Snow

Snow forms when the temperature in the atmosphere is below freezing (0°C or 32°F) and there is enough moisture present to form ice crystals. These ice crystals then join together to form snowflakes. The shape and structure of snowflakes depend on factors such as temperature, humidity, and air currents.
