Which outcome occurs when a cave's ventilation decreases?

💡 Explanation

A decrease in cave ventilation reduces CO₂ outgassing, causing less calcium carbonate precipitation via the dissolution equilibium known as mineral precipitation. This slows stalactite growth because CaCO₃ remains in solution, rather than depositing; therefore rate decreases, rather than increasing speleothem decay.
