← GeographyWhich outcome arises when freeze-thaw cycles erode granite cirques?
A)Increased glacial headwall erosion✓
B)Decreased sediment stratification rates
C)Enhanced chemical weathering of bedrock
D)Stabilized permafrost layer formation
💡 Explanation
Increased glacial headwall erosion results from repeated freeze-thaw within the cirque. The mechanism is frost wedging, where water expands when freezing, because this weakens rock, rather than stabilizing it; therefore increased erosion promotes overall mass wasting not alternative actions relating to sediment layers.
