Which outcome results if a terrace farming wall fails due to hydrostatic pressure after heavy rainfall?

💡 Explanation

When a retaining wall fails, the contained soil becomes exposed to rainfall-induced erosion because lack of support accelerates soil detachment by raindrop impact then rapid water runoff. Therefore, accelerated topsoil erosion occurs, rather than increased nutrient uptake, temperature stabilization, or declining irrigation needs which rely on structure stability.
