Increased dissolution rates cause which outcome within karst topography?

💡 Explanation

Chemical weathering attacks soluble bedrock; dissolution enlarges initial joints and fractures—karstification. This positive feedback enhances subsurface drainage features, creating extensive cave systems, because increased water flow accelerates chemical weathering within voids rather than leading to surface reduction or soil formation.
