← GeographyWhich outcome occurs when groundwater evaporation exceeds recharge within aKarst cave system?
A)Clog of calcite micro-crystalline deposition
B)Stalactite elongation decreases significantly✓
C)Enhanced bacterial colony expansion occurs
D)Dissolution rate of bedrock increases rapidly
💡 Explanation
As vadose dripwater slows, precipitation occurs because the process of Calcite Deposition (CaCO3 precipitates from the water) is limited by water availability therefore, stalactite elongation decreases, rather than clogging which would suggest sufficient mineralized water still dripping.
