Which weathering outcome impacts cavern formation specifically because of karst topography and groundwater?

💡 Explanation

Increased carbonic acid dissolution is critical to cavern formation: groundwater absorbs CO2, forming carbonic acid that dissolves limestone via chemical weathering; cavern develops; therefore, dissolution rates increase, rather than oxidation/thermal fluctuation/exfoliation–which affect surface weathering.
