Perito-Moreno glacier in Patagonia, Argentina
A glacier is a large, long-lasting river of ice that is formed on land and moves in response to gravity. Glacier ice is the largest reservoir of fresh water on Earth, and second only to the oceans as the largest reservoir of total water. Glaciers are found on every continent except Australia.Photo credit: Chmouel Boudjnah
