What is the correct relationship between Deccan Trap and black soil?
Answer and explanation
Correct answer: Black soil developed from lava rocks of Deccan Trap
The correct answer is B. The Deccan Trap was formed by extensive volcanic lava flows, and the weathering of its basaltic rocks contributed to the development of black, clay-rich regur soil across large parts of the Deccan region. This soil can retain moisture and is traditionally associated with cotton cultivation, although crops depend on several conditions. Option A is wrong because glacial ice does not form the Deccan Trap. Option C confuses volcanic basalt with marine coral, and option D is incorrect because the characteristic soil is not simply sandy. The relationship is therefore geological: basaltic lava rocks weathered over time and helped produce black soil.
