← GeographyWhich erosion process primarily sculpts cirques within glaciated mountain ranges?
A)Freeze-thaw weathering and plucking✓
B)Chemical weathering solution widening
C)Abrasion by loess particle impact
D)Sheetwash flow and gully incision
💡 Explanation
When temperatures cycle around freezing, freeze-thaw weathering weakens the rock face, and glacial plucking, where ice freezes around rock fragments and pulls them away, occurs because of ice expansion, forming a bowl-shaped depression. Therefore, freeze-thaw and plucking results, instead of soilution widening, loess impacting, or sheetwash erosion, each needing different conditions.
