📖 Read the story
Imagine you are climbing a very high mountain. At the bottom, you can see green grass and beautiful flowers. But as you go up, the air gets very cold. Soon, you see white snow on the ground. The snow line is the place where the green ground stops and the snow begins. Above this line, it is too cold for the snow to melt. On warm mountains, this line is very high up. But near the cold North Pole, the line is very low. In summer, the snow line moves up because the weather is hot. In winter, it moves down. Did you know there are also snow lines in space? Far away from hot stars, water turns into hard ice. This space snow line helps scientists find new planets. Would you like to see a snow line one day?
