Most of the Deccan Plateau is associated with which type of rocks?
Answer and explanation
Correct answer: Lava rocks
The governing concept is the geological origin of the Deccan Plateau. Much of the plateau is covered by thick layers of basalt formed when fluid volcanic lava spread over the surface and cooled. Repeated ancient eruptions produced the characteristic Deccan Trap landscape, so option B, lava rocks, is correct. Alluvial deposits are mainly associated with river plains, especially the northern plains; coral rocks form in particular warm shallow marine environments; and glacial rocks are linked with ice action, not the broad volcanic plateau of peninsular India. The rock type therefore provides evidence of the plateau’s volcanic history and explains why the Deccan is often linked with basaltic lava.
