Snow can be fun to play in. When it snows, you can go sledding. You can also make snowballs. Even though snow is cold, it can be a lot of fun. Have you ever wondered how snow is made? Clouds have water vapor in them. Water vapor is water that is not a liquid. It is a gas. Have you ever seen a pot of water boil, and then steam rises from it? That steam is water vapor. So, how is snow made from that? Well, when the temperature is cold enough, the water vapor freezes into a crystal form. That crystal form becomes a snowflake. Snowflakes have six sides. No two snowflakes are alike. They are different sizes and have different patterns on them. Snow can also be dangerous, especially when driving. People have to be very careful when driving in snow because it makes the roads slippery. Warmer places, like in the southern United States, do not get much snow. It doesn't get cold enough there for snow.
