In India, rigid and stable elevated lands, denuded rocks and series of scarps are the features of which of the following?
- A.Northern mountains
- B.Peninsular plateau
- C.Northern plains
- D.Coastal plains
Correct answer
Explanation
The correct answer is B, Peninsular plateau. The plateau is part of the ancient Gondwana landmass, so it is a rigid, stable block worn down by long erosion.
The Peninsular plateau is made largely of old crystalline, igneous and metamorphic rocks and is one of the oldest landmasses of India. Because it has stood above the sea for so long, its rocks are heavily denuded, its hills are rounded and worn, and faulting has left lines of scarps, such as the Western Ghats along its western edge. Broad shallow valleys, residual hills and tablelands mark its surface. It is divided mainly into the Central Highlands and the Deccan Plateau.
A is wrong because the northern mountains, the Himalayas, are young fold mountains that are still rising and are unstable, with frequent earthquakes. C is wrong because the northern plains are flat surfaces of recent alluvium laid down by rivers, not denuded rock. D is wrong because the coastal plains are narrow low strips of marine and river deposits.
Exam tip: Himalayas young and unstable; Peninsular plateau old, rigid and stable, part of Gondwana land.
