History

Which outcome occurs when pre-Columbian chinampas agriculture experiences prolonged drought conditions?

A)Increased soil salinity from evaporation
B)Enhanced nitrogen fixation by soil bacteria
C)Improved crop yields through water stress
D)Decreased pest populations due to dryness

💡 Explanation

When drought persists, increased evaporation from the chinampas leads to salt accumulation in the soil as dissolved minerals are left behind. Therefore, increased soil salinity occurs, rather than improved yields, nitrogen fixation, or decreased pests which all rely on adequate moisture levels to maintain the specific agricultural processes.
