Explanation / Answer
Option C is correct.
The carbonate platforms of Florida.
Karst is a term used for the characteristic terrain produced by the chemical erosion of carbonate rocks such as limestone and dolomite. Acidic water dissolves the carbonate rock along cracks and fractures in the bedrock. Most precipitation is of relatively neutral pH but becomes increasingly acidic as it infiltrates live plant tissue, decaying plant debris, and soils before seeping into the ground. Over thousands of years, dissolution within pore spaces and along fractures creates increasingly larger voids.
