How is a cirque stairway explained?
Answer and explanation
Correct answer: By glacial erosion and overdeepening at several elevation levels
A cirque stairway is a sequence of cirque basins arranged at different elevations, often separated by rock steps or thresholds. It forms through repeated or differential glacial erosion and overdeepening as mountain ice occupies successive positions or changes its erosive focus. Option A is therefore correct. Sea-wave deposition, loess accumulation, and delta formation are processes of different environments and do not produce this stepped glacial arrangement.
