What is Snow Made of? Snowflake Facts for Kids
Most kids love snow! They love playing in the snow, sled riding, building forts and snowman and of course the fun snowball fights. Kids love hearing the weather man predict a large snowstorm, because that means no school and a fun day in the snow. But, what exactly is snow and where does it come from? Find out below with these fun facts about snow.
What is Snow?
Snow are small flakes of ice that fall down to the earth. Snow is a form of precipitation like rain and sleet. It snows when water in the atmosphere freezes into crystals. These tiny ice crystals form together to make snowflakes. To snow the temperature must be below 32 degrees.
In order to snow the air temperature must be low below 32 degrees and there must be a lot of moisture in the sky. For this reason snow is common is areas of high latitudes, mountainous regions and in places that get really cold. These places include northern states of the US, and even some southern states, Russia, Canada, Europe, Greenland, Antarctica, and many parts of Asia.
How Big is a Snowflake?
The size of a snowflake depends on how many ice crystals connect together. Each snowflake is made up of about 200 ice crystals. Snowflakes have six sides. Many people say that no two snowflakes are exactly alike, however there is no scientific proof of this.
On average snowflakes fall from the sky at 3-4 miles per hour.
Close to 80% of the worlds fresh water supply comes from snow and ice.
Snow is not actually white, but clear. It looks white because of the way the light reflects off of the ice crystals.
Snow didn’t always look white. When coal was used widespread in factories and homes a lot of coal dust traveled through the air. The coal dust was absorbed in the clouds and when it snowed it often looked gray from the air pollution.
Different Types of Snow
