← HistoryWhich outcome occurs when increased sediment deposition accumulated within a chinampa system?
A)Enhanced soil fertility via nutrients
B)Elevation increase past water table✓
C)Reduced flooding impact via berms
D)Faster decomposition of root structures
💡 Explanation
When excessive sediment is deposited, the chinampa's surface elevation increases because material accumulation exceeds decomposition, eventually surpassing the water table and preventing essential capillary action for continued root hydration. Therefore the soil dries out, rather than improving fertility, reducing flooding significantly, or faster decomposition, which are enabled by differing conditions.
