← HistoryWhich risk increased for Mayan hydraulic systems following deforestation?
A)Erosion-induced aqueduct sedimentation✓
B)Reduced crop photosynthetic rates
C)Decreased soil nitrogen fixation
D)Inadequate water channel infiltration
💡 Explanation
Aqueduct sedimentation risk increased due to heightened soil erosion from deforestation; the hydraulic *transport of sediments* clogged and impaired aqueducts, because rainwater carried more soil. Therefore the drainage structures were compromised rather than solely the crop yields.
