← GeographyWhich outcome occurs when freeze-thaw action erodes mountains?
A)Cirque enlargement via headwall retreat✓
B)Arête formation from glacial abrasion
C)Esker deposition via meltwater tunnels
D)Kettle lakes form behind stagnant ice
💡 Explanation
As freezing and thawing cycles weaken rock, glacial plucking, termed headwall retreat, enlarges a cirque basin because ice accumulation amplifies erosion rather than esker formation. Therefore, cirque enlargement increases, rather than other processes.
