The Patagonian plateau of Argentina and the Piedmont plateau of the eastern United States are examples of:
- A.Piedmont plateaus
- B.Intermontane plateaus
- C.Lava plateaus
- D.Dissected plateaus
Correct answer
Explanation
The correct answer is A, piedmont plateaus. A piedmont plateau lies at the foot of a mountain range with a plain or the sea on its other side, and it is usually lower than an intermontane plateau; Patagonia lies between the Andes and the Atlantic, and the Piedmont plateau of the United States between the Appalachians and the Atlantic coastal plain. Option B is wrong because an intermontane plateau such as Tibet or Bolivia is shut in by mountains on all sides. Option C is wrong because a lava plateau such as the Deccan Trap or the Columbia plateau is built of basalt sheets. Option D is wrong because a dissected plateau such as Chotanagpur is one that streams have carved into separate blocks; dissection describes what happened to a plateau later, not how it rose.

- A.Intermontane plateau
- B.Lava plateau
- C.Piedmont plateau

Show answer
The Deccan Trap was built by fissure eruptions of highly fluid basalt lava towards the close of the Cretaceous period, which spread as sheet after sheet over a vast area of western and central India; the weathering of that basalt gives the black cotton soil, also called regur.
