What is the difference between continental glacier and piedmont glaciers ?
Piedmont glaciers, which occur only in high latitudes, are formed by the spreading of valley glaciers where they emerge from their valleys or by the confluence of several valley glaciers. A continental glacier is a huge mass of ice that covers a lot of land near the Arctic or Antarctic polar regions. Continental glaciers are found in and around the Arctic, Antarctic circles, Greenland and islands in the polar regions. These huge glaciers are nothing more than huge chunks of ice that began with a single snowfall. First a layer of snow falls in one area. After a while more snow falls until the layer is thicker. Each time a new layer of snow falls it adds weight to the glacier. The layers below the top layer begin to squeeze together until most of air is squeezed out from between the particles of snow. At this point ice forms from the crushed snow. So, the lower ice layers in a glacier are thinner and denser than the layers toward the top of the glacier. This process has gone on for milli
