How are valleys formed by glaciers?

Best Answers

Valley glaciers Valley glaciers are streams of flowing ice that are confined within steep walled valleys, often following the course of an ancient river valley. The downward erosive action of the ice carves the valley into a broad U shape, in contrast to the steeper V shape that is produced during the early stages of erosion by rivers. read more

U-shaped valleys are formed by glacial erosion as massive mountain glaciers moved slowly down mountain slopes during the last glaciation. U-shaped valleys are found in areas with high elevation and in high latitudes, where the most glaciation has occurred. read more

When the glaciers melt, the tributary troughs are left as hanging valleys high on the walls of the main glacial valley. Postglacial streams may form waterfalls from the mouths of the hanging valleys, a well-known example being Yosemite Falls, California. read more
