← HistoryWhich outcome directly increased agricultural yields from ancient chinampas?
A)Nutrient concentration via hydraulic sorting✓
B)Wind protection via elevated platforms
C)Salinity reduction via managed outflow
D)Thermal regulation via subterranean channels
💡 Explanation
Chinampas improved crop production via hydraulic sorting, which concentrates organic matter delivering nutrients to crops. This soil enrichment boosts yields, because it provides essential elements, therefore crops thrive on chinampas rather than on depleted land.
