Q. Consider the following statements:
- The Meghalaya Plateau and the Karbi Anglong Plateau are joined by Rajmahal hills from the main Peninsular Block.
- The Meghalaya Plateau has a highly eroded surface due to high rainfall.
- The Meghalaya Plateau is devoid of mineral resources unlike Chotanagpur Plateau.
Which of the above is / are correct?
Answer:
Only 1, 2, and 3
Notes: It is believed that due to the force exerted by the northeastward movement of the Indian plate at the time of the Himalayan origin, a huge fault was created between the Rajmahal hills and the Meghalaya Plateau. Later, this depression got filled up by the deposition activity of the numerous rivers. Today, the Meghalaya and Karbi Anglong Plateau stand detached from the main Peninsular Block. Similar to the Chotanagpur Plateau, the Meghalaya Plateau is also rich in mineral resources like coal, iron ore, sillimanite, limestone and uranium. This area receives maximum rainfall from the south-west monsoon. As a result, the Meghalaya Plateau has a highly eroded surface. Cherrapunji displays a bare rocky surface devoid of any permanent vegetation cover.
