CHAPTER FIVE
Ice and Snow
In the mountains, you can see rivers of ice! A river of ice is called a glacier.
What makes a glacier? In winter, lots of snow falls on the mountains. Then, new snow falls on the old snow and makes ice. The ice moves down the mountain in a glacier. Glaciers move very, very slowly.
In some glaciers, there are big crevasses. Crevasses are holes in the ice. Crevasses are dangerous. In snowy weather, people don’t see a crevasse. Then they can fall in.
Avalanches are dangerous, too. In an avalanche, lots of snow falls from the mountain. It can fall on people.
