During Inca terracing construction, which consequence results from inadequate subsurface drainage?

💡 Explanation

The risk of landslides increases because increased pore water triggers a reduction in effective stress manifesting in liquefaction of the soil during seismic events; therefore slope instability is the immediate safety consequence, rather than chemical effects on the nutrients.
