Have you ever seen snow falling before? Each bit of snow that falls from the sky is made of snowflakes. But what is a snowflake?
A snowflake is a tiny ice crystal. It can form when the air is very cold. Water vapor in the air can freeze into ice crystals. When that happens in clouds, snowflakes form!
Snowflakes are very small. It can be hard to tell what each one looks like. But if you could, you’d be in for a treat. They can form many different patterns!
