U-shaped valleys provide evidence of glacial erosion.
To determine the answer to this multiple-choice question, we need to understand what U-shaped valleys are and which process is responsible for their formation.
First, let's define U-shaped valleys. U-shaped valleys are landforms typically found in mountainous regions that have been carved out by glaciers. These valleys have a wide, flat bottom with steep, straight sides, resembling the shape of a "U."
Now let's consider the given options for the process responsible for the formation of U-shaped valleys:
1. Deposition: This process refers to the laying down of sediment or particles on the Earth's surface. It does not involve the carving or shaping of valleys.
2. Glacial erosion: This process involves the erosion or wearing away of rock and soil by glaciers as they move across the landscape. Glacial erosion is indeed responsible for the formation of U-shaped valleys.
3. Wind erosion: Wind erosion occurs when wind transports and removes loose particles or sediment from the Earth's surface. While wind can shape other landforms, it is not the primary process behind the formation of U-shaped valleys.
4. Coastal erosion: Coastal erosion refers to the wearing away of land along coastlines by the action of waves and currents. It is unrelated to the formation of U-shaped valleys.
Based on this analysis, the correct answer is "glacial erosion." U-shaped valleys provide evidence of glacial erosion processes.
