Which risk increases when Inca agricultural terracing exceeds angle limits?

💡 Explanation

Increased steepness exceeds soil’s shear strength facilitating slope failures through mass wasting, because gravitational force overwhelms cohesion, therefore landslides are more likely rather than simple soil alteration under normal conditions.
