Which outcome resulted from the ancient Andean civilizations' usage of terrace farming on steep slopes experiencing heavy rainfall?

💡 Explanation

When Andean civilizations used terrace farming on steep slopes with heavy rainfall, they achieved microclimate control because the level terraces slowed water runoff, enabling even water and nutrient distribution. Therefore crop yield variability decreased, rather than increased erosion or landslide susceptibility which would derive from uncontrolled water flow and instability.
