The steps in the formation of South Asian subcontinent?

The Indian Plate, which forms the majority of the South Asian subcontinent, was once part of the supercontinent Gondwana. Gondwana began to break up around 200 million years ago, and the Indian Plate began to drift northward.

Step 2: Collision with Eurasia

Around 50 million years ago, the Indian Plate collided with the Eurasian Plate. This collision caused the formation of the Himalayas, as well as the Tibetan Plateau. The collision also resulted in the closure of the Tethys Ocean, which had once separated India from Eurasia.

Step 3: Subduction of the Indian Plate

As the Indian Plate continued to move northward, it began to subduct beneath the Eurasian Plate. This subduction caused the formation of the Hindu Kush mountain range, as well as the Karakoram mountain range.

Step 4: Formation of the Deccan Plateau

Around 65 million years ago, a volcanic eruption occurred on the Indian Plate. This eruption resulted in the formation of the Deccan Plateau, which covers much of central and western India.

Step 5: Present Day

The Indian Plate continues to move northward, and the collision between the Indian and Eurasian plates is still ongoing. This collision is responsible for the continued uplift of the Himalayas and the Tibetan Plateau.
