Which feedback results on Inca terracing when improperly compacted soil leads to hillside deformation?

A)Increased surface runoff and erosion
B)Enhanced nutrient retention and pooling
C)Decreased slope stability calculations
D)Accelerated plant growth and stabilization

💡 Explanation

Soil compaction failures on Inca terraces causes increased surface runoff and erosion by reduced infiltration; this is because the hydraulic conductivity changes rather than creating improved drainage conditions. The change initiates soil destabilization, therefore causing slope erosion rather than improving landscape cohesion.
