← GeographyWhich mechanism inhibits continued stalactite growth after cave saturation?
A)Capillary action limiting water supply
B)Carbon dioxide equilibrium stabilizing calcium✓
C)Groundwater acidity increasing mineral erosion
D)Airflow causing increased calcium evaporation
💡 Explanation
Stalactite growth stops due to Carbon Dioxide Equilibrium; dissolved CO2 shifts the bicarbonate & calcium balance toward dissolution, because excess water prevents CO2 escape, increasing calcium solubility, therefore inhibiting deposition rather than causing continued growth via drip evaporation alone.
