Which erosion pattern increases where terrace walls degrade?

💡 Explanation

Enhanced sheet erosion occurs because degraded terrace walls reduce slope stabilization, leading to increased water flow velocity concentrating sediment removal; therefore sheet erosion dominates, rather than localized deposition or channel incision due to widespread overland flow.
