How is snow formed?

Published: Jul 28 2011 12:22:30 PM EDT

Snow is commonly formed when water vapor changes directly to ice without first becoming a liquid, this process is known as deposition.

When temperatures of less than 32°F are at the higher altitude in the atmosphere the ice crystals are created.

The snow flakes are able to stay frozen as they fall because the temperatures stay below 32°F all the way to the ground.
