← GeographyWhich glacial outcome is intensified with freeze-thaw cycles?
A)Cirque erosion deepening and widening✓
B)Esker sediment deposit lengthening
C)Drumlin plain surface ice expansion
D)Kettle lake shoreline sediment stabilization
💡 Explanation
Cirque erosion intensifies; freeze-thaw causes rock weathering and glacial plucking, because ice lens formation expands fractures; therefore, the cirque grows via nivation, rather than sediment stabilization or esker/drumlin formation by depositional features.
