← HistoryWhich 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.
