← GeographyWhich acceleration in erosion occurs where mountain permafrost thaws?
A)Increased freeze-thaw weathering intensity✓
B)Expansion of alpine meadow vegetation
C)Reduced river sediment deposition rates
D)Decreased glacial ice ablation
💡 Explanation
Increased freeze-thaw weathering occurs because permafrost thaw introduces more water subject to freeze-thaw cycles which mechanically breakup rock, therefore leading to accelerated erosion, rather than biological or depositional changes.
