Which risk increases as freeze-thaw cycles erode cirques?

💡 Explanation

Increased erosion leading to thinner barriers can increase the likelihood of glacial like outburst floods, because headwall weakening during nivation promotes dam collapse: therefore GLOFs are more likely, rather than other geological processes like sinkhole creation being related.
