← GeographyWhich feedback occurs when polar ice decline decreases albedo?
A)Increased thermohaline circulation✓
B)Accelerated volcanic outgassing
C)Decreased coastal erosion rates
D)Stabilized atmospheric CO2 levels
💡 Explanation
Reduced albedo leads to increased solar absorption in oceans, causing warmer temperatures and altering the density gradient, because thermohaline circulation is driven by temperature and salinity differences. Therefore, circulation rate increases rather than other outcomes; volcanic activity and erosion are independent.
