← HistoryWhich outcome occurred when annual flooding inundated Aztec chinampas during maize cultivation?
A)Nitrogen depletion due to soil erosion
B)Increased soil salinity from mineral deposits
C)Anaerobic conditions inhibiting root growth✓
D)Phosphorus runoff promoting algae blooms
💡 Explanation
When chinampas flooded, anaerobic conditions developed because waterlogging displaced oxygen in the soil, inhibiting maize root respiration at the cellular level. Therefore, inhibited root growth resulted, rather than erosion, salinity increases, or algal blooms, which depend on drainage or connectivity to open water systems.
