Question
History

Which outcome emerged as excessive terrace construction during pre-Columbian maize cultivation altered watershed dynamics?

A)Increased downstream sediment deposition
B)Enhanced soil nutrient retention locally
C)Improved regulation of river flow
D)Reduced frequency of slope failures

💡 Explanation

Increased sediment emerged because erosion accelerated via increased runoff: soil detachment exceeds holding capacity, therefore sediment outflow increases, rather than sediment deposition reduction or improved hillslope stability.
