One well-known Christmas song is "White Christmas." The lyrics talk about dreaming of a white Christmas. It was written in 1942. Soldiers in World War II loved the song. Snow inspired that songwriter. Children dream of snowflakes, too. They want to have a day off from school!
Places that get cold in winter can enjoy a white holiday. Snowflakes cover the ground with a white blanket. They start in a cloud. They start when water vapor cools in the air. The water condenses. It changes from a gas to a liquid. Then the liquid freezes into an ice crystal. It starts out very small. Then the crystal grows. It gets more complex. It blows around inside the cloud. Then it falls to Earth.
