Which feedback mechanism enhances cirque formation at high altitudes?

💡 Explanation

When differential weathering weakens the rock, freeze-thaw cycles mechanically erode the cirque walls, concentrating the erosive power. Therefore differential weathering enhances cirque formation, rather than albedo reduction, permafrost stabilization, or vegetation effects which influence different glacial processes.
