What feature is typically created by the action of glaciers?

Glaciers are powerful agents of erosion and are known for their ability to shape the landscape in distinctive ways. One of the key features they create is a U-shaped valley. This formation occurs as glaciers move through mountainous regions, carving out the walls of the valley and deepening it over time. Unlike river valleys, which tend to have a V-shape due to the erosion caused by flowing water, U-shaped valleys retain a wide, flat floor and steep sides, a result of the glacier's immense weight and movement.

As glaciers advance, they pick up and transport sediment and rocks, further modifying the landscape. When they retreat, they often leave behind this distinctive U-shaped profile, which is a hallmark of glacial erosion. This feature can be clearly observed in many mountain ranges around the world and serves as an important indicator of past glacial activity.
