Which of the following terms is globally used to describe steep-walled, rugged rock steps or vertical cliffs formed by glacial headwall erosion, which are prominently seen in the cirques of Uttarakhand?

💡 Solution & Explanation

Cirque headwalls are steep, amphitheater-like cliffs carved at the head of a glacier by the process of plucking and freeze-thaw weathering. Moraines are ridge deposits of till, nunataks are rocky peaks protruding above ice sheets, and arenes are wind-blown sand features. Cirques and their headwalls are fundamental landforms studied in glacial geomorphology across all mountainous continents.
