Which mechanism most directly causes cave formation in karst landscapes?

💡 Explanation

Cave formation primarily initiates from the carbonic acid dissolution mechanism; rainwater absorbs CO2, becoming a weak carbonic acid that dissolves limestone bedrock. Therefore, caves enlarge through this process, rather than from tectonic forces, glacial erosion, or igneous activity.
