Which form arises during cirque enlargement through freeze-thaw?

💡 Explanation

Bergschrund development accelerates upslope erosion because enhanced pressure-release cracking produces headwall fracturing within the cirque. This nivation accelerates *mass wasting*, therefore headwall retreats rather than depositional glacial features forming.
