Which consequence arises when poorly designed Inca terracing experiences intense rainfall?

💡 Explanation

Soil collapse occurs because increased saturation triggers slope instability via increased pore water pressure; this reduces the effective stress holding the soil together. Therefore, terraces fail catastrophically, rather than experiencing gradual erosion given functional drainage.
