← GeographyWhich cave formation process stops completely during droughts?
A)Calcite precipitation equilibrium✓
B)Groundwater table fluctuation
C)Evaporite mineral replacement
D)Hydrostatic pressure gradient
💡 Explanation
Calcite precipitation, generating speleothems, depends on dissolved calcium carbonate reaching saturation; because groundwater flow ceases during a drought, the calcite reaches thermodynamic equilibrium with existing rock rather than depositing more material; therefore no growth occurs, rather than changes to the water table.
