Which structural failure was most common when constructing pre-Columbian agricultural terraces on steep Andean slopes?

💡 Explanation

When soil behind a terrace wall becomes saturated due to rainfall or irrigation, hydrostatic pressure increases because the water table rises and exerts a lateral force against the wall, often leading to its collapse. Therefore wall collapse results, rather than erosion, crop failure or landslides; which require different triggering events.
