Glaciers are often called “ rivers of ice. 13 of 30. Thick sheets of ice. 1: Glacial Erosion and Deposition - Geosciences LibreTexts Tarns are common in areas of alpine glaciation because the ice that forms a cirque typically carves out a depression in bedrock that can then fill with water. In some cases, a series of such basins will form, and the resulting lakes are Lakes are typical features of glacial environments. They form mainly in association with glacial features such as cirque basins and kettleholes, and on a wide range of erosional landforms such as small fault scarps and slumps. Tarns are small depressions filled with water on the cirque floor. B) tarns. They are called "cirque glaciers" if they originate in small bowls with steep headwalls (cirques). Skip to Content Shop the latest Skyblue Gear Alpine Glacial Geomorphology About 69% of Earth's freshwater is frozen, with the bulk of that ice sitting restlessly in just two places, Greenland and Antarctica. Alpine glaciers form when Describe and identify the various landforms related to alpine glacial erosion, including U-shaped valleys, arêtes, cols, horns, hanging valleys, truncated spurs, drumlins, roches moutonées, glacial grooves, and striae.
