Glacial landscapes are formed by the movement and melting of glaciers, which are large masses of ice that flow slowly over land. As glaciers advance, they carve out valleys, shape mountains, and create features like U-shaped valleys, fjords, and moraines. These landscapes often exhibit rugged terrain and unique geological formations. When glaciers melt, they leave behind a variety of landforms, including glacial lakes and kettle holes. The sediment deposited by glaciers, known as glacial till, can create fertile soil in some areas. Glacial landscapes are often found in polar regions and high mountain ranges, showcasing the powerful effects of ice on the Earth's surface.
