India is a country located in South Asia, bordered by the Himalayan mountains to the north and surrounded by the Indian Ocean, Arabian Sea, and Bay of Bengal. The formation of India is a complex process that involves geological, tectonic, and evolutionary factors.

Geological Formation:
India was once a part of the supercontinent Gondwana, which existed around 550 million years ago. Over time, tectonic movements caused Gondwana to break up, and India drifted northward towards the Eurasian Plate. This movement caused the Indian Plate to collide with the Eurasian Plate, resulting in the formation of the Himalayan mountains.

Tectonic Activity:
The Indian Plate's collision with the Eurasian Plate caused massive tectonic activity, including earthquakes, volcanic eruptions, and the formation of the Deccan Traps. The Deccan Traps are a large volcanic province located in western India and were formed around 66 million years ago.

Evolutionary Factors:
India's unique biodiversity is a result of its isolation from other landmasses for millions of years. The Indian subcontinent broke away from Africa and Antarctica around 100 million years ago, and its isolation allowed for the development of unique flora and fauna.

In conclusion, the formation of India is a complex process that involves geological, tectonic, and evolutionary factors. These factors have contributed to the formation of India's diverse geography and unique biodiversity.

As a result of this collision, the sedimentary rocks which were settled in the large scale depression in the Earth's crust called Tethys were folded and Himalayas were formed joining the present land form of India with the Eurasian plate......
