Which risk accelerated bronze implement degradation during Late Bronze Age drought cycles?

💡 Explanation

When water tables dropped, capillary action wicked subsurface water with increased chloride concentrations to the surface, causing increased chloride salt corrosion due to electrochemical reactions with bronze forming soluble copper chlorides. Therefore increased chloride induced corrosion resulted, rather than thermal stress, embrittlement, or microbial risks which operated independently of chloride.
