← GeographyWhich pedogenic outcome occurs when carbonic acid weathering increases?
A)Increased dissolution of carbonate bedrock✓
B)Enhanced retention of clay minerals
C)Reduced soil organic matter oxidation
D)Decreased iron oxide precipitation
💡 Explanation
Greater carbonic acid enhances the dissolution of carbonate bedrock via chemical weathering because increased acidity accelerates carbonate mineral breakdown. Therefore, increased bedrock dissolution occurs, rather than the stabilization of minerals, or organic matter oxidation alterations.
