WebThe key feature of alpine glacial erosion is the U-shaped valley. Arêtes are sharp ridges that form between two valleys, and horns form where a mountain is glacially eroded on at least three sides. Because tributary glaciers do not erode as deeply as main-valley glaciers, hanging valleys exist where the two meet. WebThese are known as U-shaped valleys (Figure 17.17). In contrast, unglaciated river valleys generally have a V shape. Figure 17.17 A depiction of a U-shaped valley occupied by a large glacier. Source: Steven Earle (2016) CC BY 4.0 view source.

"WebGlacial erosion causes the formation of U-shaped valleys, whereas V -shaped valleys are the result of carving by the rivers through their course. U-shaped valley walls are straighter than V-shaped valleys due to the non-bending glacier’s movement. Glaciers do not get influenced easily by rock hardness as are rivers.

How U-shaped valleys are formed? – Rattleinnaustin.com

Web…valley is converted to a U-shaped valley because the U-shape provides the least frictional resistance to the moving glacier. Because a glacier has a much greater viscosity and cross section than a river, its course has fewer and broader bends, and thus, the valley becomes straighter and smoother. WebCorries, pyramidal peaks and u-shaped valleys form due to glaciation. Glaciated uplands are used for different land uses which can lead to conflict; strategies must be adopted to deal with these.
