How Does Snow Form?

Snow is a type of precipitation that is frozen. Precipitation is part of the water cycle. Precipitation is when liquid water falls to the ground. This happens when a cloud becomes heavy and all the water will fall to the ground. There are three different types of precipitation. Rain, snow, sleet, and hail. We are going to focus on snow!

Snow is different from frozen rain. Snow is made up of tiny ice crystals that are so small that they feel like powder. When snow falls to Earth, the ice crystals expand and build up on the surface of the ice particle. That creates snowflakes! To start the process, the water droplets in clouds have to collide with dust particles to make them heavy enough to freeze! Snow usually comes down during the Winter season on cold days, but there are some times when snow comes on cold Summer days as well!
