glacial erosion
U-shaped valleys provide evidence of glacial erosion.
U-shaped valleys provide evidence of glacial erosion.
To arrive at this answer, we need to understand the formation and characteristics of U-shaped valleys:
1. Start by recalling the shape of a typical U-shaped valley. It has steep, straight sides and a flat or gently sloping bottom.
2. Next, consider the process of glacial erosion. Glacial erosion occurs when a glacier moves down a mountain or through a valley, slowly scraping and eroding the surrounding landscape.
3. Glaciers are powerful agents of erosion, due to their immense weight and movement. As a glacier progresses, it scours the valley floor and sides, carving out the surrounding bedrock and sediment.
4. This glacial activity results in the distinctive shape of a U-shaped valley, with its characteristic steep and straight sides, and flat or gently sloping bottom.
Hence, based on this understanding, we can conclude that U-shaped valleys provide evidence of glacial erosion.
