Which risk increases when Inca agricultural terraces experience excessive rainfall on steep slopes?

💡 Explanation

When terraces receive excessive rainfall, hydraulic erosion occurs because the water runoff exceeds the soil's infiltration capacity eroding away the fertile topsoil from the terraces. Therefore topsoil loss occurs, rather than nutrient leaching, pest infestations, or decreased sunlight which arise through different processes.
