Which consequence results when groundwater velocity decreases within subterranean karst cave systems?

💡 Explanation

Decreasing groundwater velocity reduces the transport capacity of dissolved minerals, increasing mineral precipitation via chemical precipitation. Because residence time increases, mineral saturation occurs more readily, therefore speleothems form more quickly rather than increased bedrock dissolution which demands faster flow.
