← HistoryWhich agricultural outcome resulted from Mesoamerican chinampa construction in shallow lake beds?
A)Decreased soil salinity from continuous irrigation
B)Nitrogen depletion due to monoculture planting
C)Enhanced carbon sequestration from reduced tilling
D)Consistent crop yields during seasonal floods✓
💡 Explanation
When chinampas were constructed, the raised beds prevented standard seasonal flood damage because canals allowed controlled water flow, moderating inundation, and providing nutrient replenishment. Therefore consistent crop yields resulted, rather than increased salinity, depletion, or sequestration which require distinct environmental processes and soil compositions.
