← GeographyWhich outcome occurs when groundwater’s carbon concentration changes within limestone?
A)Cave formation via mineral dissolution✓
B)Increased seismic hazard potential
C)Enhanced silicate weathering rates
D)Accelerated thermohaline circulation.
💡 Explanation
Cave formation results if increased groundwater carbon reacts with calcium carbonate; mineral dissolution occurs because the elevated carbonic acid levels accelerate the breakdown of rock, therefore caves are formed rather than shifting tectonic plates.
