Explanations:The northeastern region of India is a complex geological area with various plateaus and mountain ranges. The Peninsular block, also known as the Peninsular Plateau, is a significant geological formation that extends into the northeastern region of India. This block is characterized by its stable and ancient crystalline rocks, which are part of the Indian subcontinent's foundation.
The Karbi Anglong and the Meghalaya Plateau are part of this geological extension. The Karbi Anglong is a plateau located in Assam, and the Meghalaya Plateau is a plateau in the state of Meghalaya. Both of these plateaus are formed from the same ancient rock formations that make up the Peninsular block. This means that they are indeed extensions of the Peninsular block, which is why the first statement is correct.
On the other hand, the Chotanagpur plateau is a distinct part of the Peninsular Plateau. It is located in the eastern part of India, primarily in the states of Jharkhand, Chhattisgarh, and Odisha. The Chotanagpur plateau is characterized by its rolling hills and is part of the larger Peninsular Plateau. Therefore, the second statement is incorrect, as the Chotanagpur plateau is indeed part of the Peninsular Plateau.
Understanding the geological formations and their origins is crucial for comprehending the geographical features of India. The Peninsular block is a significant geological formation that extends into various parts of the country, including the northeastern region. The Karbi Anglong and the Meghalaya Plateau are part of this geological extension, while the Chotanagpur plateau is a distinct part of the Peninsular Plateau.
It is important to note that the geological formations in India are diverse and complex, and understanding their origins and characteristics is essential for a comprehensive understanding of the country's geography. The correct answer to this question is that the first statement is correct, as the Karbi Anglong and the Meghalaya Plateau are indeed extensions of the Peninsular block.
