Which mechanism causes increased cirque erosion following deglaciation?

💡 Explanation

Increased freeze-thaw cycles after glacial ice melts cause frost shattering because water enters cracks and expands, fracturing the rock. Therefore this accelerates cirque erosion, rather than chemical or aeolian weathering that occur much slower.
