Which outcome results when groundwater calcium concentration drops significantly and rapidly within a karstic cave system containing active stalactites?

💡 Explanation

Stalactite growth slows because limestone precipitation via carbonate equilibrium (a crystallization process) requires sufficient calcium and bicarbonate; therefore the formation rate drops significantly, rather than faster precipitation which requires increased, ion concentrations in the drip water.
