What Is Snow Made Of?

Snow is made out of tiny ice crystals that stick together. The tiny ice crystals form when the temperatures are low and there is moisture in the atmosphere.

The formation of the ice crystals determines the size of the snowflakes. The colder the air is, the more powdery and lighter the snow is. If the temperature is slightly warmer, the crystals bond together making larger, wetter snowflakes. Each snowflake has a unique shape, but they all have a hexagonal figure. The temperature must be at least 35.6 degrees Fahrenheit. The lower the temperature is, the longer it takes the snow to melt.
