What is Karst topography primarily associated with?

Correct option is A

The correct answer is (a) Groundwater action in limestone or dolomite regions.
• Karst topography is formed due to chemical weathering (solution and carbonation) of limestone and dolomite rocks by groundwater, creating features like sinkholes, caves, and underground streams.
Information Booster:
• Named after the Karst region of Slovenia and Italy.
• Major features: stalactites, stalagmites, dolines, and limestone caverns.
• Common in Meghalaya (Krem Liat Prah Caves) and Visakhapatnam (Borra Caves).
• Carbonic acid from rainwater dissolves calcium carbonate (CaCO₃).
• Represents fluvial-erosional landform under subsurface drainage.
Additional Knowledge:
• Karst regions are rich in groundwater aquifers.
• Found in Yunnan (China) and Appalachians (USA) globally.
• Studied under geomorphology in physical geography.
