← GeographyWhich feedback loop slows permafrost thaw within cirques?
A)Surface albedo temperature reduction✓
B)Methanogenesis greenhouse effect increase
C)Vegetation soil organic matter loss
D)Coastal erosion thermal energy absorption
💡 Explanation
Glacial erosion causes cirques that increase surface ice, resulting in higher albedo; this albedo amplifying feedback reduces local temperature. Therefore, ice reflects more light, rather than increased methanogenesis trapping heat.
