Snow is a type of ice that falls from the sky. It is composed of individual ice crystals that grow while they are suspended in the atmosphere or within a cloud. When they fall to the ground, the crystals undergo further changes. These changes cause the snow to be white. To understand snow, one must first understand its composition.
Snow is a very complex material and scientists study its properties in many ways. They study the chemical bonds between its constituent parts, cloud formation, snowpack, and snowmelt. Their findings are applied to a variety of fields, including engineering, agronomy, and the design of snow equipment. They also develop classification systems for snow based on its physical properties.
Snow forms when temperature and moisture levels are just right. The ideal temperature for snow formation is below freezing. The optimal moisture content in the air prevents the snow crystals from melting in such low temperatures. This makes snow an ideal insulator. This slows the flow of heat from the warm ground to the cold air.
Snow crystals are formed as a result of tiny ice grains that come together. The resulting structure is unique. Unlike the ice crystals in other materials, each snowflake has six points and sides. This means they can take the shape of a star, needle, or dendrite. Some snowflakes may also have plates on the top or sides.
