← GeographyWhich landscape outcome results when carbonic acid dissolution weakens bedrock?
A)Karst topography expansion✓
B)Sand dune stabilization
C)Glacial moraine formation
D)Volcanic caldera collapse
💡 Explanation
Karst topography expands because carbonic acid dissolution chemically weathers soluble rocks like limestone by dissolving the calcium carbonate. This creates fissures and sinkholes; therefore karst regions result, rather than landforms from glacial or volcanic processes.
