← GeographyWhich topographic consequence arises when glacial abrasion enlarges cirques?
A)Arête formation becomes more pronounced✓
B)Esker deposition rates decrease sharply
C)Kame terraces experience differential settling
D)Drumlin alignment shifts perpendicularly westward
💡 Explanation
More pronounced arête formation occurs because backwall glacial erosion via the Bergschrund effect deepens adjacent cirques, therefore sharpening the ridges between them rather than depositing eskers.
