Which benefit did pre-Columbian terracing provide specifically in regions with significant seasonal rainfall?

💡 Explanation

When intense seasonal rainfall occurs on sloped land, terracing creates level platforms acting as barriers and slowing water runoff, meaning that erosion is reduced. Therefore, topsoil erosion rates decrease, rather than pollination increases, frost resistance or nitrogen fixation, all of things that require independent mechanisms.
