EROSION BY GROUNDWATER A. Carbonate rocks--water moves through factures in limestone or marble, dissolves and enlarges openings H 2 O + CO 2 -- &gt H 2 CO 3 (rain) Carbonic acid B. Karst topography--that which results from groundwater dissolution of carbonates e.g. sinkholes, disappearing streams, solution valleys C. Cave formation--combined effects of weathering and erosion by groundwater 1.
