← GeographyWhich mechanism strongly controls mineral deposition rates forming stalactites?
A)CO2 dissolution decreasing solid solubility✓
B)Insolation rate decreasing drip volume
C)Groundwater pressure increasing mineral saturation
D)Oxidation increasing solution carrying capacity
💡 Explanation
A stalactite forms because CO2 dissolution decreases calcium carbonate solubility via Henry's Law, therefore calcite precipitates at drip points, rather than staying dissolved due to higher CO2 concentration maintaining solubility underground.
