Related terms

Karst Topography: A type of landscape characterized by features such as sinkholes, caves, and underground rivers, formed primarily through the dissolution of soluble rocks.

Dissolution: The process through which a solid substance dissolves in a solvent, leading to a change in the state of matter, commonly observed in karst formations when minerals like limestone are dissolved by acidic waters.

Acidic Water: Water that has a low pH due to the presence of dissolved carbon dioxide, organic acids, or other compounds, which enhances its ability to dissolve carbonate rocks and create karst features.
