Snow and ice falls on the interior of the Antarctic continent. The weight of the ice slowly pushes it down hill. This moving ice is called a glacier.
Glaciers slowly flow downhill towards the coast. It can take thousands of years for ice from the interior of the Antarctic continent to reach the coast. The largest Antarctic glacier is the Lambert Glacier, 40 km wide and 400 km long. It is also the largest glacier in the world.
Glaciers are rivers of ice. Have students investigate how they move and the distinctive features they form. They should include features like crevasses, ice shelves, icebergs and moraines. They can also answer the question: why are glaciers blue?
