← HistoryWhich adaptive outcome results when Andean terraced fields experience intense rainfall?
A)Accelerated rate of soil salination
B)Improved stability against landslides
C)Reduced nutrient runoff downstream✓
D)Increased risk of waterlogging occurs
💡 Explanation
Terraces reduce nutrient run-off because step-like structures slow water flow and sediment transport via the deposition mechanism. Therefore more nutrients are retained within each level, rather than eroding and depleting field fertility.
