← GeographyWhich outcome results when basal sliding accelerates in cirques?
A)Increased glacial abrasion and cirque erosion✓
B)Decreased ice volume and equilibrium line
C)Stabilized ice flow and sediment transport
D)Reduced meltwater production and cryoconite formation
💡 Explanation
Increased basal sliding elevates abrasion because enhanced ice movement over bedrock accelerates glacial erosion within the cirque leading to a deeper, wider basin. Therefore, increased abrasion occurs, rather than stabilization, due to frictional forces exceeding resisting friction.
