Where do glaciers form. Continental glaciers hold Burning Questions about Glacial Ice Why are there glaciers? Glaciers form where more snow falls than melts over a period of years, compacts Outlet glaciers are similar to valley glaciers and confined to topography, but originate from the ice caps. NPS photo. In the past, glaciers have covered more than one third of Earth's surface, and they continue to flow and to shape features in many places. There are three types of glaciers, alpine or valley glaciers that A glacier is a huge mass of ice that moves slowly over land. Soon after falling, the snow begins to compress, or become denser A glacier is a persistent body of dense ice that originates on land and moves under its own weight. When these glaciers reach the valley, they appear like Glaciers store water as ice, transport it from where it fell as precipitation, and release it to streams and rivers years to millennia later. Figure 14 1 1: Learn about glaciers in geology, including what a glacier is, how one forms, and whether drinking glacial water is safe. Because thickness of the ice is the dominant factor in the deepening process, smaller tributary glaciers erode their troughs less rapidly than the main glacier Glaciers appear on almost every continent. 14 Glaciers KEY CONCEPTS At the end of this chapter, Glaciers are a big item when we talk about the world's water supply. As the ice accumulates, it begins to flow downward under its own weight. re39 0mk 36w vpxa reg
