Gis forGlacier

A glacier is a very large amount of ice that is slowly moving. The ice comes from fallen snow in an area that is so cold the snow just keeps building up faster than it melts away. There is an enormous amount of fresh water frozen inside glaciers, which are found all over the world except Australia. Because glaciers move and are so big and hard, they can change the landscape as they move. The ice from the glaciers eventually ends up in the sea.
