Which risk increased during Chinampa construction at excessive depths?

💡 Explanation

Soil oxygen is reduced at greater depth leading to soil structural compromise because decomposition outpaces oxygen supply establishing anaerobic conditions; therefore, root health diminishes, rather than enhanced soil collapse, sedimentation, or insolation playing primary limiting roles.
