← HistoryWhich outcome resulted from the controlled flooding of chinampas agriculture by the Aztecs across the Valley of Mexico?
A)Increased soil salinity from evaporation
B)Nutrient replenishment via sediment deposition✓
C)Decreased crop yield from waterlogging
D)Enhanced pest resistance through crop rotation
💡 Explanation
When Aztec chinampas were flooded deliberately, sediment deposition occurred because floodwaters carried nutrients and organic matter from surrounding highlands, leading to fertile soil replenishment. Therefore nutrient replenishment resulted, rather than salinity, yield decrease, or pest resistance which each necessitate alternative environmental dynamics.
