On historic chinampa systems in Mesoamerica, which consequence results when freshwater supply is insufficient?

💡 Explanation

Increased soil salinity inhibits maize crop yields, because capillary action draws salts to the surface under drier conditions where *evaporation* occurs; therefore increased soil salinity, rather than nutrient leaching will affect harvests.

• In Aztec chinampa agriculture, which consequence arises if the capillary action delivering water to maize roots experiences high evapotranspiration?
• Which outcome increases the risk of catapult inaccuracy when launching projectiles during a siege?
• Which limitation arises when an astrolabe measures sunrise timing in a high-humidity environment?
• In ancient Mesopotamia, which risk increased during the casting of large bronze objects when using clay molds?
• Which effect caused inaccuracies with medieval Islamic astrolabes tracking distant stars near the horizon?
• Which outcome arises from differential settlement in historical masonry aqueduct piers?
