WebFeb 12, 2013 · Glaciers are a big item when we talk about the world's water supply. Almost 10 percent of the world's land mass is currently covered with glaciers, mostly in places like Greenland and Antarctica. You can think of a glacier as a frozen river, and like rivers, they "flow" downhill, erode the landscape, and move water along in the Earth's water cycle. WebGlaciers move in two ways. The first way is through the pull of gravity and meltwater. Gravity pulls the heavy weight of the glacier down a hill very slowly. If you were watching one, you probably wouldn't see it moving. Under the glacier, as it slowly moves, the rocks it is dragging underneath cause the ice to melt.

A good guess is that the ice thickness is about one-half of the surface width of the glacier. Although few glaciers have been measured, the measured thicknesses range from a few tens of meters for small glaciers to about 1,500 meters for the largest glaciers in Alaska.
