Question

Quizplus · Accepted Answer

The feature described is most likely a glacial valley or U-shaped valley, which forms through the merging of cirques by headward erosion. This is the process by which a glacier erodes backward into a mountainside, creating a bowl-shaped depression called a cirque. As multiple cirques merge, they form a larger valley with a characteristic U-shaped cross section. Thus, option B is the most apt choice.
