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.
