Which consequence occurs when terrace steps erode in pre-Columbian agriculture?

💡 Explanation

Increased downslope runoff occurs because of decreased stepped SURFACE ROUGHNESS reducing infiltration; therefore, water volume rapidly accelerates downslope, rather than being absorbed, intensifying general land erosion and soil destabilization during heavy rainfall events.
