Explanation:
The given statements are related to the geological divisions of the Indian subcontinent. Let's analyze each statement separately:
Statement 1: Himalayan mountain chain was part of Laurasia or Angaraland geological divisions.
The Himalayan mountain chain is a result of the collision between the Indian plate and the Eurasian plate. It is a relatively young mountain range that is still growing. However, during the geological past, the Indian plate was not part of Laurasia or Angaraland.
Laurasia was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, approximately 300 to 200 million years ago. It was formed by the splitting of the earlier supercontinent, Pangaea. Laurasia included present-day North America, Europe, and Asia (excluding the Indian subcontinent).
Angaraland, also known as the Siberian continent, was another supercontinent that existed during the late Paleozoic era, approximately 550 to 250 million years ago. It included present-day Siberia, Kazakhstan, and parts of China.
Therefore, statement 1 is incorrect.
Statement 2: Peninsular India was part of Gondwanaland of Geological divisions.
Gondwanaland, also known as Gondwana, was a supercontinent that existed during the late Paleozoic and early Mesozoic eras, approximately 550 to 180 million years ago. It included present-day South America, Africa, Antarctica, Australia, the Indian subcontinent, and the Arabian Peninsula.
Peninsular India, also known as the Indian Plate, was indeed part of Gondwanaland. The Indian subcontinent was located in the southern hemisphere during that time and was connected to the other landmasses of Gondwanaland.
Therefore, statement 2 is correct.
In conclusion, only statement 2 is correct. Peninsular India was part of Gondwanaland, while the Himalayan mountain chain was not part of Laurasia or Angaraland.
