RAS question
Which of the following is NOT a physiographic region of Rajasthan?
Correct answer: (A) Deccan Plateau.
The Deccan Plateau is not a physiographic region of Rajasthan.
Explanation
Rajasthan Foundation's page on topographical divisions says Rajasthan is divided into four main physiographic regions: the Western plain, the Aravalli Range, the Eastern Plains, and the south-eastern plains or Hadoti Plateau. These correspond to Western Sandy Desert, Aravalli Range, Eastern Plains, and Southeastern Plateau (Hadoti). The Deccan Plateau does not appear in this official four-region classification, so it is the odd option in the list. The question is therefore testing recognition of Rajasthan's internal physiographic map, not a general recall of Indian plateaus.
Why the other options are wrong
- (B) Eastern Plains is wrong as the answer because the official Rajasthan Foundation list names the Eastern Plains as one of Rajasthan's four main physiographic regions.
- (C) Aravalli Range is wrong as the answer because the official list includes the Aravalli Range among Rajasthan's four main physiographic regions.
- (D) Western Sandy Plains is wrong as the answer because it corresponds to the Western plain or Western Sandy Desert, which is part of Rajasthan's four-region physiographic classification.
Concept
This tests the Rajasthan Geography syllabus area on physiographic divisions of the state. It recurs in RAS because many location, drainage, climate, agriculture, and regional-development questions depend on first placing a district or feature in the correct physiographic region.
