Question

Difficulty: MediumPhysiography and Relief Features of India

Consider the following statements regarding the structural and relief features of the Peninsular Plateau of India:

1. The Central Highlands lie to the north of the Narmada River and are bounded by the Aravalli range on the northwest.
2. The Deccan Plateau is higher in the east and slopes gently towards the west.
3. The Western Ghats form a continuous relief wall that can be traversed only through passes, whereas the Eastern Ghats are discontinuous and dissected by major east-flowing rivers.

Which of the statements given above is/are correct?

  1. 1 and 3 onlyAnswer
  2. B
    1, 2 and 3
  3. C
    2 and 3 only
  4. D
    1 and 2 only

Answer

1 and 3 only
The correct response identifies statements 1 and 3 as true statements. The Central Highlands lie north of the Narmada River, and the Western Ghats are structurally continuous compared to the breached Eastern Ghats. The second statement is incorrect because the Deccan Plateau is higher on the western side and slopes towards the east, as evidenced by the drainage pattern of most major peninsular rivers.

Step-by-Step Solution

1
Analyze Statement 1 regarding the position of the Central Highlands.
Statement 1 is correct. The portion of the Peninsular plateau lying north of the Narmada River is broad and classified as the Central Highlands, demarcated by the Aravallis on the northwest and Vindhyas on the south.
Topographical boundaries confirm the northern extent of the Peninsular block.
2
Analyze Statement 2 regarding the regional slope of the Deccan Plateau.
Statement 2 is incorrect. The Deccan Plateau has a higher elevation in the west (Western Ghats region) and slopes gently towards the east, as demonstrated by the eastward flow of rivers like the Godavari, Krishna, and Cauvery.
River drainage direction highlights the west-to-east tilt of the Peninsular shield.
3
Analyze Statement 3 regarding the comparative relief continuity of the Western and Eastern Ghats.
Statement 3 is correct. The Western Ghats form a continuous escarpment (navigable via passes like Thal Ghat, Bhor Ghat, and Palghat), whereas the Eastern Ghats are fragmented and eroded by major east-flowing peninsular rivers.
Geological erosion patterns differ between the elevated Western margin and dissected Eastern margin.
