← HistoryWhich advantage did chinampa construction provide for Aztec cultivation in the Valley of Mexico?
A)Increased water availability via raised beds✓
B)Reduced frost risk with deep soil layers
C)Enhanced soil fertility from volcanic rock
D)Improved resistance against droughts
💡 Explanation
When constructing chinampas, the Aztecs created raised beds surrounded by canals, increasing water availability via capillary action because it connected the plants directly to the lakebed. Therefore, increased water availability resulted, rather than frost protection, soil fertility enhancement, or drought resistance, which involve different environmental adaptations.
