Which geologic configuration develops where carbonic acid promotes weathering?

💡 Explanation

Extensive karst topography occurs when the dissolution of carbonate rocks by weak carbonic acid forms networks of caves and sinkholes, creating porous features; this is dissolution weathering. Therefore, karst landscapes are linked to carbonic acid presence rather than alluvium, glaciation mechanisms, or volcanic forces.
