Which outcome occurs as rainwater percolates karst layers?

💡 Explanation

The dissolution of carbonate minerals causes cave formation, because carbonic acid forms from rainwater reacting with atmospheric carbon dioxide; therefore, minerals dissolve rather than accumulating layers and folding differently behaving rocks.
