← HistoryWhat outcome accelerated terrace erosion in ancient Peru?
A)Deforestation reduced slope stability✓
B)Aqueducts increased water discharge
C)Earthquakes triggered structure collapse
D)Terraces changed climate patterns
💡 Explanation
Deforestation removed vegetation cover, thereby diminishing soil cohesion via root reinforcement. This lack of root structure caused the earth terraces to loosen and become prone to landslides because there was less structural support, rather than remaining intact with vegetation.
