← HistoryWhich risk increased in early Chinampa agriculture when waterlogged lands were over-extended?
A)Salt accumulation degraded soil✓
B)Methane release amplified climate
C)Nutrient stratification disrupted planting
D)Bacterial blooms polluted crops
💡 Explanation
Increased irrigation without drainage caused capillary action which left behind dissolved mineral accumulations; Salinization reduces cultivation because the process depends on a rising supply of water from the soil and evaporation, therefore it harms fertility rather than alternatives under drained conditions.
