← HistoryWhich agricultural consequence arose when chinampas utilized hydraulic soil consolidation in the Valley of Mexico?
A)Reduced soil salinity near surface
B)Increased anaerobic conditions lower✓
C)Elevated mineral content in crops
D)Decreased waterborne disease risk
💡 Explanation
When constructing chinampas, nutrient-rich mud was dredged from the lakebed, which has high organic content, resulting in water displacement from downward pressure and consolidation of the mud. Elevated anaerobic breakdown occurred from restricted oxygen. Increased anaerobic conditions lower results, rather than reduced salinity, increased minerals, or decreased disease risk because they are not immediate consequences hydraulic layering.
