Which environment change accelerates carbonate deposition as stalactites form?

💡 Explanation

A decrease in cave CO2 causes dissolved carbon dioxide in the water droplet to be released because the carbonate equilibrium shifts, which decreases the carbonic acid concentration; therefore, calcium carbonate precipitates rather than remains in solution by other environmental fluctuations.
