← GeographyWhich outcome occurs when water undergoes evaporative enrichment within a carbonatic cave system?
A)Increased speleothem deposition rate✓
B)Decreased atmospheric carbon dioxide levels
C)Slower karst weathering processes
D)Greater groundwater calcite solubility
💡 Explanation
Evaporative enrichment increases the saturation index, driving calcium carbonate precipitation via supersaturation. This leads to a faster rate of stalactite and stalagmite formation because the solution becomes heavily saturated; therefore increasing speleothem growth, rather than other dissolution effects.
