What is the term used in geomorphology to describe the steep-sided, amphitheater-like hollow carved into a mountain by the headward erosion of a glacier, many of which contain tarn lakes in Himachal Pradesh?

💡 Solution & Explanation

A cirque is a bowl-shaped, steep-walled glacial depression formed at the head of a glacial valley where snow and ice accumulate and erode rock through freeze-thaw weathering and plucking. Moraines are ridges of unsorted debris deposited by moving glaciers. Glacial cirques are prominent landforms across the Dhauladhar and Pir Panjal ranges.
