Later deposition. Perhaps searching can help. This study guide looks at glacial landforms that are created by processes of erosion and deposition. The processes include understanding how ice masses move, erode, transport and deposit sediment. Glacial processes and landforms. Nearly all glacially scoured erosional landforms bear the tool-marks of glacial abrasion provided that they have not been removed by subsequent weathering. What is firn? While permafrost has been a characteristic feature of these landscapes, climate change is slowly reducing its presence and creating challenges for human society. Vertical and lateral erosion . STUDY. Upper or Youth Stage. Why are they important?-provide a valuable resource-generate electricity-support the skiing industry -site of mineral extraction. A. Erosional Processes- The movement of ice and the pressure exerted on the underlying earth surface result in capability of glaciers to perform great amounts of erosion and earth sculpturing. 3.

Subglacial release (shearing and/or melting) Ablation; dumping; pushing; Glacial fluvial - deposited by glacial meltwater Glacial marine/lacustrine . There are several types of moraine: (1) lateral moraine: forms along each side of a glacier (2) medial moraine: if two glaciers with lateral morains join, a medial moraine may form. Where does continental glacial ice still exist? First, at the base of a glacier, large amounts of loose rock and sediment are incorporated into the moving glacial ice by partial melting and refreezing. Glaciers form whenever snowfall exceeds snowmelt year after year. 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. Glaciers shape the land through processes of erosion, weathering, transportation and deposition, creating distinct landforms. Some areas, like Fennoscandia and the southern Andes, have extensive occurrences of glacial landforms; other areas, such as the Sahara, display rare and very old fossil glacial landforms. Flashcards.

What is a glacier? The floor of this valley is bowl-shaped and receives the bulk of the impact of the ice flows from multiple directions and the accompanying rock particles and other debris. PLAY. The second process of erosion involves the abrasive action of the held rock and sediment held by the ice on the surface underneath the glacier. Terms in this set (17) Describe the process of transforming snow to firn and then to glacier ice.
