A topographic term for the landscape and structures formed in soluble bedrock by the effects of solution weathering. Karst regions are characterized by subterranean caverns, sinkholes, and dolines. Karst typically results from the action of mildly acidic water percolating through limestone, gypsum, or dolomite. As the rock dissolves, it becomes more porous and underground drainage systems develop.
