On steep Andean slopes, which key benefit did terrace construction provide for maize cultivation, mitigating a critical risk?

💡 Explanation

Terrace construction on steep slopes reduces soil erosion because the level platforms interrupt water runoff and diminish water flow, preventing intense soil detachment and downhill transport. Therefore, reduced soil erosion is the key benefit, rather than increased sunlight, nitrogen fixation, or lower temperature which require other optimization mechanisms and environmental conditions.
