Which long-term consequence resulted from intensive maize cultivation displacing diverse wetland vegetation on Aztec chinampas?

💡 Explanation

When the Aztecs shifted from varied wetland vegetation to intensive maize, soil compaction occurred because the deep, complex root systems of the native plants were replaced by shallow maize roots, reducing soil support. Therefore, land subsidence results, rather than humidity, disease resistance, or aquifer recharge, which are associated with different vegetation characteristics.
