Snow is so much fun. Don’t you just love scrunching around in it, having snowball fights, going sledding and building snowmen?
But even though it’s cool fun have you ever thought about how snow is made, and how it lands up in our suburbs for super cool fun? Well we’re going to tell you all about how snow is made.
There are little water vapors in the air and before they turn into water, they freeze and form crystals of ice. But why does this happen? Basically this is when the temperature way up there in the clouds is seriously cold, making ice instead of water. This is when snowflakes are made which fall as snow. Snow falls in soft flakes and they’re joined lightly together, and each flake is made up of tiny crystals.
Snowflakes are made of crystals of ice that form from bits of dirt in the air. Each snowflake could have as many as 200 crystals in them! Wow!
Did you know that each snowflake is completely different to the next? Well amazingly they are. They all have a geometrical shape made up of five points. When snowflakes collect, the snow gets packed together. Because its own weight they squeeze out the air from the middle of the flakes.
Ultraviolet radiation – the sun sends different rays to Earth. You will see some of them as sunlight. Some of them you can’t see. The ones you can’t see are called “ultraviolet” rays or “UV rays.” These rays are the ones that can make your skin burn.
Now you know all about snow, go out and play and ace that next test!
