So you think you know about glaciers?
Glaciers can be found all over the world, at the poles and in the great mountain ranges. You can even find glaciers at the Equator at the top of Mount Kilimanjaro in Africa. The biggest glaciers are found flowing from the ice sheets of Greenland and Antarctica and are very different to the small valley glaciers of the Alps, for example. How much do you know about these slow-moving but incredibly powerful rivers of ice?
