Which erosional landform dominates where groundwater dissolution undermines carbonate bedrock structures?

💡 Explanation

Karst topography forms because chemical weathering via dissolution enlarges fractures in soluble bedrock, therefore solution creates sinkholes, caves, and underground drainage, rather than fluvial, glacial, or aeolian landforms that dominate other regions.
