GLACIER

By     Joe Sullivan  A glacier is a moving ice field that moves into ways. The two ways are creeping and crevasse. Crevasse is when the glacier melts a little and moves leaving crack called crevasse. Creeping is when it slides on ice crystals so it looks like its creeping down the mountain. The Muir Glacier was formed when snow falls on mountain and traps air. The snow freezes the air gets out and turns blue. This is called an ice field. When an ice field moves it’s a glacier. The Muir Glacier is now a lot of glacier because of climate change. It was named after John Muir who studied and explained what it was. In 1925, it was a National Monument. In 1980, it was named a Nation Park called Glacier Bay Nation Park. In conclusion, the Muir Glacier is one of the glaciers that will’ melt into the ocean one day.
