Which consequence resulted when Inca agricultural terraces exceeded wall stability limits?

A)Reduced soil fertility occurred rapidly
B)Terrace collapse induced landslides downhill
C)Decreased sunlight exposure harmed plants
D)Excessive erosion depleted water reserves

💡 Explanation

Complete Inca terraces suffered collapse due to exceeding structural capacity; the mechanism is slope instability. This causes landslides because the angle of repose was decreased, therefore destabilizing upper terraces, rather than simply reducing soil fertility.
