1. Karst Topography Dissolved Carbonate Rock 80+ either:
Calcium Carbonate
Limestone
Dolomite
Must have fissures for water transport.
High water table and weather pattern with lots of rain.
CaCO2 + H2O—CaCO3 +H
Carbonic Acid continues to weather the Limestone or Dolomite, which mixes with water and becomes Carbonic Acid, and so on.

4. Wet Cave
A Wet Cave has standing water in the form of ponds or lakes, or moving water in the case of underground streams or dripping water from surface percolation.

5. Sinkholes Sinkholes, the Movie
