What Are Glaciers?

Glaciers are large moving rivers of ice. Glaciers form when snow is compressed into a large object that is made of ice. This only happens where the temperature doesn’t reach high enough for the snow and ice to melt completely. Glaciers take hundreds of years to form because the snow has to pile up over time to create giant glaciers! Glaciers can range from small clumps to huge slabs that go on for miles!! Glaciers make up 10% of the Earth’s surface, from the Arctic regions of Canada, to Greenland, to Alaska. Glaciers move due to their weight and gravity. As they move, they can form lakes and even valleys! That is what glaciers are.
