Which flow pattern contributes to speleogenesis in karst regions?

💡 Explanation

Preferential dissolution initiates cave networks because it leverages weaknesses within the bedrock. This focused reaction accelerates weathering along pre-existing fissures, therefore creating larger conduits, rather than a uniform weathering pattern.
