← GeographyWhich factor limits stalactite formation rate the most?
A)Carbon dioxide equilibrium rate✓
B)Cave airflow convection speed
C)Limestone impurity concentration
D)Dissolved iron oxidation state
💡 Explanation
Slower carbon dioxide equilibrium in dripping water reduces calcium carbonate precipitation via Le Chatelier's principle, thereby significantly limiting the stalactite formation rate; therefore, lower gas exchange, rather than cave airflow, determines the mineral deposition's speed.
