What term describes a landscape formed by the dissolution of rocks due to surface or ground water?

The term that accurately describes a landscape formed by the dissolution of rocks, particularly soluble rocks like limestone, is "Karst." Karst landscapes are characterized by features such as sinkholes, caves, and underground rivers, all formed through the chemical weathering process where acidic water gradually dissolves the rock over time. This unique geological formation occurs when carbon dioxide from the atmosphere or soil combines with rainwater to create carbonic acid, which then interacts with the rock structure, leading to the distinctive topography associated with karst regions.

Understanding this process and its resultant features is crucial for cavern divers, as it informs them about the underwater environments they may encounter, including potential hazards and navigational considerations in these often complex and dynamic systems. This knowledge is essential for safe and effective diving practices in such environments.
