Glaciers shape the landscape through processes such as erosion, deposition, and transportation of sediments. As glaciers move, they scrape and grind the underlying rocks, creating U-shaped valleys, cirques, and fjords. The sediments carried by glaciers are deposited as moraines, drumlins, and eskers, altering the land's topography. Glaciers also play a significant role in carving out features like arĂȘtes and hanging valleys due to their erosive power.
