Which erosional effect accelerates cirque formation located on a northern-facing mountain aspect at high latitude?

💡 Explanation

When a cirque is located on the north side in high latitudes, increased freeze-thaw weathering cycles occurs because it reduces insolation and maximizes ice formation, accelerating the plucking and abrasion crucial to cirque erosion. Therefore, freeze-thaw weathering is the primary driver, rather than acid rain, aeolian abrasion or geothermal activity, all of which require alternate conditions.
