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.
Web…valley is converted to a U-shaped valley because the U-shape provides the least frictional resistance to the moving glacier.
