← GeographyWhich outcome results when increased atmospheric carbon dioxide concentration accelerates weathering of limestone?
A)Intensified karst topography formation✓
B)Stabilization of cave ecosystem equilibrium
C)Reduced seismic activity in carbonate regions
D)Enhanced fossil preservation rates
💡 Explanation
Accelerated carbon dioxide dissolution weathers limestone intensifying karst formation because carbonic acid production increases rock erosion; therefore sinkholes and caves expand rather than ecosystems stabilizing, seismic changes occurring, or fossils being better preserved.
