Which landscape outcome is fostered by karst system dissolution?

💡 Explanation

Subsurface caves form by carbonic acid dissolving bedrock via chemical weathering; this is karst dissolution in action because chemical reactions break down the limestone rather than physical forces. Therefore, cave system formation occurs rather than faster deposition or resisted erosion processes.
