Which outcome results from cumulative soil creep on ancient agricultural terraces built on steep slopes?

💡 Explanation

When soil creep occurs continuously on terraces, downslope movement of soil accumulates over time because of gravity and weathering, increasing pressure on retaining walls. Therefore wall collapse and landslides result, rather than increased runoff, nutrient depletion or salinization which are caused by different environmental stressors or farming practices.
