← HistoryWhich mechanism allowed chinampas (floating gardens) in Aztec agriculture to sustain year-round cultivation despite seasonal flooding?
A)Capillary action drawing water upwards✓
B)Evaporative cooling delaying plant growth
C)Nitrogen fixation enriching soil biota
D)Thermal inertia moderating temperatures
💡 Explanation
When water tables rise during floods, capillary action draws the moisture upwards through the porous chinampa soil because water molecules are attracted to soil particles, providing consistent irrigation. Therefore capillary action allows year-round irrigation, rather than other processes which do not involve consistent re-distribution via internal water table dynamics.
