Snow forms by a process of deposition, which means that water vapor in the high in the atmosphere changes directly into ice without becoming a liquid first. The temperature must be below freezing (32oF) for this to occur. If snow meets any warm air as it falls to the ground, it can be turned into rain, sleet or freezing rain.

Snowflakes come in many shapes and sizes, but each one is six-sided. They form from as many as two hundred ice crystals, which come together in a lattice structure around a tiny piece of dust or dirt.

Fun Fact –  Snow is white because the crystalline structure reflects all light, making it appear white to our eyes.
