Which environmental adaptation enables pre-Columbian Andean terraced fields to prevent widespread topsoil loss after heavy rainfall?

💡 Explanation

During heavy rainfall gravity-fed channels are constructed because angled drains efficiently remove excess surface water flow velocity, averting erosion. Therefore topsoil loss is reduced after rainfall, rather than relying solely on permeability, plowing, or nitrogen fixation to control runoff mechanics and prevent soil displacement .
