Which of the statements above is/are correct?

Correct option is D

The correct answer is (d) 1, 3 and 4 only

Explanation:

1. The Eastern Ghats and Western Ghats meet at the Nilgiri Hills.
• The Nilgiri Hills in Tamil Nadu form the junction point of the Eastern and Western Ghats.
2. The Thar Desert is the most densely populated desert in the world.
• While the Thar Desert is one of the most populated deserts, it is not the most densely populated in terms of population per square kilometre among all deserts globally. It ranks among the more populated ones but not the topmost by density.
3. The Patkai or Purvanchal ranges are part of the Eastern Himalayas.
• The Patkai hills are part of the Eastern Himalayas, extending through Arunachal Pradesh and Nagaland. These are a part of the Purvanchal ranges.
4. The Satpura range is formed by a series of scarped plateaus on the south, generally at an elevation varying between 300–400 m above mean sea level.
• The Satpura Range, found in central India, is made up of block mountains and scarped plateaus, often with elevations around 300–600 m in some parts.

Information Booster:

• Nilgiri Hills: Located at the tri-junction of Kerala, Karnataka, and Tamil Nadu. They are important for biodiversity and tea plantations.
• Purvanchal Range: Includes the Patkai Hills, Naga Hills, Mizo Hills (Lushai Hills), and Manipur Hills; an extension of the Himalayas into the Northeast.
• Satpura Range: Runs east to west, between the Narmada and Tapi rivers; formed due to block faulting.
• Thar Desert: Located primarily in Rajasthan; known for its relatively higher desert population but not the densest globally.
