Which challenge did ancient Inca terrace farming specifically overcome, relating to water's downslope movement?

💡 Explanation

The terraced fields reduced soil erosion by interrupting downslope water flow via stepped barriers. This induced Sedimentation because erosion decreases, water velocity drops, and gravity deposits soil behind terraces; therefore, soil remained within the agricultural plot rather than being washed away.
