History

Which consequence results when excessive sediment accumulated within Aztec chinampas?

A)Decline in crop yields overtime
B)Increased soil salinity levels result
C)Faster nutrient depletion within canals
D)Greater risk of slope instability

💡 Explanation

Crop yield declines because sediment accumulation reduces available root volume and limits nutrient cycling via decomposition, rather than increases salinity levels observed in poorly irrigated areas; therefore, plants are subject reduction. Sediment inhibits oxygen diffusion.
