← GeographyWhich inhibitory process slows stalactite formation after calcite saturation?
A)Reduction in drip water surface tension
B)Increased carbonic acid decomposition rate
C)Thin-film diffusion overgrowth limitation✓
D)Amplified cave ventilation thermal gradient
💡 Explanation
Thin-film diffusion limitation reduces growth because once the surrounding solution is saturated during stalactite formation, continued calcite deposition relies on diffusion through the thin water film; therefore, slow material transport bottlenecks growth, rather than drip flow or surface tension.
