A glacier is a large, long-lasting river of ice that is formed on land and moves in response to gravity.
A glacier is formed by multi-year ice accretion in sloping terrain.
Glaciers can be found on every continent, including on the greater Australian continent.
Glaciers are more or less permanent bodies of ice and compacted snow that have become deep enough and heavy enough to flow under their own weight.
Glacier ice is the largest reservoir of freshwater on Earth, and second only to oceans as the largest reservoir of total water.
