Which outcome results when increased atmospheric carbon dioxide concentration accelerates weathering of limestone?

💡 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.
