Which benefit results from terraced hillside farming during the Inca empire's expansion?

💡 Explanation

When terraced farming is implemented on hillsides, soil erosion is reduced because terraces interrupt the downhill flow of water, decreasing its velocity and erosive power. Therefore reduced soil erosion results, rather than mineral extraction, pollination enhancements, or decreased frost, which require different environmental mechanisms.
