← GeographyWhich outcome occurs when carbon dioxide concentrations increase within karst cave systems?
A)Increased dissolution of carbonate bedrock✓
B)Decreased formation of speleothems
C)Enhanced precipitation of calcium carbonate
D)Reduced chemical weathering of silicates
💡 Explanation
Increased CO₂ elevates carbonic acid levels, accelerating bedrock dissolution via the dissolution-precipitation equilibrium mechanism; because carbonic acid reacts with limestone, bedrock erosion increases. Therefore, dissolution accelerates, rather than slowing speleothem formation or affecting silicate weathering.
