Glaciers are large, slow-moving masses of ice that form over many years from accumulated snowfall. They are found in polar and high-altitude regions, and they are formed when more snow falls each year than melts. Over time, the weight of the accumulating snow compresses the layers beneath it into ice. Glaciers can range in size from small, valley glaciers to vast ice sheets, such as those covering Antarctica and Greenland.
