Which outcome occurs when increased atmospheric CO2 enters groundwater?

💡 Explanation

Increased CO2 in groundwater results in enhanced subsurface weathering via carbonic acid formation; this is acid dissolution. This causes karst topography, because the carbonate bedrock dissolves, which forms caves, sinkholes, rather than altering silicate weathering rates.
