← GeographyWhich outcome initiates cirque development in mountain systems?
A)Nivation beneath perennial snow patches.✓
B)Isostatic rebound after ice retreat.
C)Subglacial meltwater pulse outburst floods.
D)Till deposition during glacial advance.
💡 Explanation
Nivation contributes to cirque development because freeze-thaw weakens the bedrock, promoting erosion and deepening of the depression; therefore, a cirque is formed, rather than another glacial feature caused by ice movement alone.
