← GeographyWhich form arises during cirque enlargement through freeze-thaw?
A)Bergschrund development accelerates upslope erosion✓
B)Eskers form due to subglacial melts
C)Kames deposit unsorted glacial sediment
D)Drumlins elongate parallel receding ice
💡 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.
