Which benefit arises when pre-Columbian Andean terraced fields manage water flow downhill during heavy rains?

💡 Explanation

When terraced fields manage water flow, energy dissipation occurs because the stepped structure slows water momentum, minimizing soil detachment and transport. Therefore topsoil retention results, rather than leaching, increased albedo, or methane production which require different hydrological conditions.
