Which environmental change is accelerated through karst cave enlargement?

A)Increased dissolved carbon atmospheric release
B)Enhanced oceanic crust subduction rate
C)Decreased global upper-stratosphere albedo
D)Increased metamorphic rock formation rate

💡 Explanation

A larger cave system increases surface area exposed to slightly acidic groundwater. Chemical weathering (dissolution) increases because greater carbonate mineral interaction boosts CO2 in ground/soil pore spaces; therefore dissolved carbon escape increases rather than other slower geological process changes.
