Which soil process led to increased agricultural output in ancient Andean terraced farming?

💡 Explanation

When sloping land is terraced, the terraced walls reduce kinetic energy of water because the horizontal surfaces intercept rainfall, significantly reducing erosion. Therefore reduced erosion resulted, rather than leaching, recharge decrease or acidification which are worsened by increased slope without terraces.
