Which primary long-term benefit did terrace farming provide in the steep Andean highlands?

💡 Explanation

Terrace farming transformed steeply sloped land into a series of level platforms; this slope reduction via terracing minimized runoff soil erosion and enhanced water infiltration and water retention. Therefore soil conservation and water capacity increased yield, rather than enhancing mineral weathering by pest control or promoting sunlight exposure which require different conditions to work.
