Introduction to Karst

The process of karst formation involves what is referred to as the carbon dioxide CO 2 cascade As rain falls through the atmosphere it picks up CO 2 which dissolves in the droplets Once the rain hits the ground it percolates through the soil and picks up more CO 2 to form a weak solution of carbonic acid H 2 O CO 2 = H 2 CO 3The infiltrating water naturally exploits any cracks or...
