On steep Andean slopes, which consequence occurs when extensive terrace walls collapse?

💡 Explanation

Terrace walls prevent soil erosion. The collapse causes increased water runoff which triggers sheet erosion because gravity overcomes the soil intertia. Therefore fertile topsoil erodes downslope rather than supporting crops due to water loss.
