← HistoryWhich challenge did ancient Inca terrace farming specifically overcome, relating to water's downslope movement?
A)Excessive soil erosion.✓
B)Unpredictable weather patterns.
C)Labor shortage for maize harvests.
D)Vulnerability to frost.
💡 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.
