← HistoryWhich consequence results when unsupported terraces saturate post-rainfall?
A)Increased global albedo decreases sunlight
B)Slumping and subsequent soil erosion✓
C)Accelerated carbon sequestration occurs
D)Decreased evapotranspiration rates occur
💡 Explanation
Slumping occurs on saturated, unsupported terraces because soil loses shear strength via pore-water pressure increase, therefore leading to downhill soil movement and rapid erosion rather than carbon uptake that results from vegetation or evaporation rates.
