Which hydrologic consequence increased risk among ancient Maya Chinampa agricultural sites after prolonged drought?

💡 Explanation

Severe droughts in the Maya lowlands caused water table decline, which exposed previously submerged, organic-rich Chinampa soils. The oxidation of organic material (peat oxidation) released sulfuric acid, acidifying the soil. Therefore, agriculture failed because of toxicity, rather than enhanced growth from nutrients.
