Q. With respect to the Karst topography, consider the following statements:
- It is well developed in limestone and chalk landforms.
- It is mainly developed when the water table is relatively high.
- Borra Caves in Uttar Pradesh is its example.
Which of the statements given above are correct?
Answer:
None of the above
Notes:
- Karst is a topography formed from the dissolution of soluble rocks such as limestone, dolomite, and gypsum. It is characterized by underground drainage systems with sinkholes and caves.
- Karst is most strongly developed in dense carbonate rock, such as limestone, that is thinly bedded and highly fractured.
- Karst is not typically well developed in chalk, because chalk is highly porous.
- Karst is most strongly developed where the water table is relatively low.
- Karsts are found in Causses of France; the Kwangsi area of China; the Yucatán Peninsula; and the Middle West, Kentucky, and Florida in the United States.
- In India karst topography is present in the Vindhya region (mainly southwestern Bihar), the Himalayas (parts of Jammu & Kashmir, Robert Cave, Sahasradhara, the eastern Himalayas, areas near Dehradun), Pachmarhi in Madhya Pradesh, Gupt Godavari Cave in Chitrakoot (U.P.), the surrounding coast near Vishakhapatnam (Borra Caves), and Bastar in Chhattisgarh.
