Glaciers consist of fallen snow that compresses over many years into large, thickened ice masses. Most of the world’s glacial ice is found in Antarctica and Greenland, but glaciers are found on nearly every continent, even Africa. Presently, about ten percent of land area is covered with glaciers. Glacial ice often appears blue because ice absorbs all other colors but reflects blue. Almost ninety percent of an iceberg is below water; only about ten percent shows above water. What makes glaciers unique is their ability to move. Due to sheer mass, glaciers flow like very slow rivers. Some glaciers are as small as football fields, whereas others grow to be over one hundred kilometers long. Within the past 750,000 years, scientists know that there have been eight Ice Age cycles, separated by warmer periods called interglacial periods. Currently, the earth is nearing the end of an interglacial, meaning that another Ice Age is due in a few thousand years. Although glaciers change very slowly over long periods, they may provide important global climate-change signals. Once compressed ice reaches a critical thickness, it becomes so heavy that it begins to deform and move. On land, lakes formed on top of a glacier during the melt season may cause floods. Glaciers also contain much of the world’s freshwater, and people have tried to harness glacial meltwater for drinking water, irrigation, and electricity.
