The results of the work of groundwater cannot be seen in all types of rocks. But in rocks like limestones or dolomites rich in calcium carbonate, the surface water as well as groundwater through the chemical process of solution and precipitation deposition develop varieties of landforms. Any limestone or dolomitic region showing typical landforms produced by the action of groundwater through the processes of solution and deposition is called Karst topography. The karst topography is also characterised by erosional and depositional landforms.
- Erosional Landforms: pools, sinkholes, lapies and caves.
- Depositional Landforms: stalactites, stalagmites and pillars.
