← HistoryWhich outcome resulted from the practice of chinampa agriculture by the Aztecs in shallow lakes?
A)Increased land fertility and crop yields✓
B)Decreased vulnerability to seasonal flooding
C)Reduced soil erosion from rainfall runoff
D)Improved water quality through natural filtration
💡 Explanation
When chinampas were extensively used, raised beds created from mud and vegetation in shallow lakes provided nutrient-rich soil and consistent moisture, increasing land fertility and crop yields through continuous cultivation. Therefore, increased fertility resulted, rather than reduced flooding or erosion, which needed drainage gradients or vegetation matting, or natural filtration, requiring slow water flow through biological media.
