Which agricultural outcome influenced urban development of the Aztec civilization using chinampa cultivation?

💡 Explanation

When chinampas created fertile plots near waterways, an increase in food surplus occurred because the raised beds provided consistent moisture and nutrient supply independent of rainfall, leading to higher population density. Therefore, increased food and density resulted, rather than erosion control, diversified yields or flood control, as other approaches meet those goals better.

• Which outcome resulted when ancient Mesoamerican chinampa farmers over-cultivated maize without nitrogen replenishment?
• Which instrumental drift affected early astrolabes during prolonged solar observations?
• Which effect caused inaccuracies with medieval Islamic astrolabes tracking distant stars near the horizon?
• Which risk increases due to soil instability in historical Andean terraced fields during prolonged intense rainfall?
• Which consequence results from exceeding timber's maximum bending moment during 18th-century 'wooden wall' warship construction?
• Which optical effect occurring in medieval astrolabes limits accuracy during twilight observations?
