Which agricultural consequence occurred in areas using a chinampa system when prolonged drought reduced water levels?

💡 Explanation

When drought reduces water levels surrounding chinampas, capillary action causes increased evaporation, leading to the upward migration of salts, and salinization of the raised beds. Therefore increased soil salinization results, rather than nitrogen depletion, soil compaction, or eutrophication which require different conditions and processes.

• Which purpose did an alidade serve in medieval Islamic astronomical instruments like astrolabes, prior to telescopic sights?
• Which mechanism primarily allowed Roman concrete structures, such as the Pantheon, to remain intact for centuries?
• Which critical process limits the success of pre-Columbian terrace farming during prolonged drought periods?
