The plateau form and black soil of the Deccan Trap are basically related to what?
Answer and explanation
Correct answer: Basaltic lava flows
The governing concept is volcanic landform formation and the relationship between parent rock and soil. The Deccan Trap was built by extensive, successive basaltic lava flows. As the basalt weathered over long periods, it produced deep dark cotton soil, commonly called regur, in many parts of the Deccan Plateau. Thus option B explains both the stepped plateau form and the associated black soil. Glacial erosion would produce a different set of erosional landforms and is not responsible for the Deccan Trap. Coral deposition occurs in marine settings, while sea tides shape coasts rather than creating this inland basaltic plateau. The correct reasoning is therefore lava flows first, followed by weathering and soil development.
