The Illustrated Glossary of Alpine Glacial Landforms is maintained by the University of Wisconsin Stevens Point's Department of Geology and Geography. As the glacier grows, the ice slowly flows out of the cirque and into a valley. Much of the debris carried by an alpine glacier comes from valley sides where talus accumulates. Matter and energy flow in an alpine glacier system. In fact, rugged mountainous areas can be made even more spectacular by glacial action. Glaciers also create distinctive landforms in the valleys they traverse (Figure C1b). Now up your study game with Learn mode.

They form on the sides of glaciers (lateral moraines) or at the boundary between two tributary glaciers (medial moraines). As alpine glaciers erode headward, they narrow the upland between ice sheets from opposite directions and a pyramid-shaped peak, called a horn is created. They over steepen valley walls, creating U . A large body of glacial ice astride a mountain, mountain range, or volcano is termed an ice cap or ice field. During the ice age, it covered nearly a third of the total area of the planet.

The upstream or stoss side is gently sloping and smooth, and the downstream or lee side is steep and rough. Describe the general appearance of the landform identified by the letter B; what would this landform look like if you could see it in person? Alpine glaciers include the valley glacier, which extends down a valley for some distance beyond the headwall area of the valley where the glacier begins. It is shaped like an amphitheater with an opening on the downhill side and a steep cupped section with cliff-like slopes on three sides. Examples of landforms by Alpine glaciers are arête, cirque, lateral moraines, hanging valley, terminal moraine, and fjords.
