← GeographyWhich risk increases extensively when freeze-thaw weathering saturates soil?
A)Extensive downslope lobe formation✓
B)Reduced nitrogen fixation rates
C)Decreased surface albedo effect
D)Accelerated chemical weathering kinetics
💡 Explanation
Increased soil saturation favors solifluction, a slow downslope movement, because viscous drag overwhelms soil cohesion leading to lobe formation; therefore, lobe formation increases rather than altered weathering or bio activity, which occur under different conditions.
