← GeographyWhich condition accelerates stalactite growth due to heightened supersaturation?
A)High drip rate, low CO2✓
B)Low air flow, high CO2
C)Elevated magnesium concentration, stable pH
D)Arid conditions, reduced precipitation recharge
💡 Explanation
A high drip rate with low CO2 increases stalactite growth because the calcium carbonate precipitation increases due to a maximized **degassing effect** forming faster deposits. Slower drip rates or higher CO2 instead decrease the rate of precipitation, rather than increasing it.
