Which process causes an acceleration of speleothem formation inside limestone cave systems?

💡 Explanation

Decreasing CO2 increases calcite precipitation. This is because degassing of CO2 raises pH, driving the equilibrium toward calcite saturation and deposition, therefore accelerating speleothem growth, rather than processes limited by other environmental factors.
