Answer» Correct Answer - Option 1 : Tethys
The Correct Answer is Tethys. - Tethys Sea, a former tropical body of water that separated the supercontinent of Laurasia in the north from Gondwana in the south during much of the Mesozoic Era (251 to 65.5 million years ago).
- There were many rivers that were flowing into the Tethys Sea (some of the Himalayan rivers are older than the Himalayas themselves.
- Sediments were brought by these rivers and were deposited on the floor of the Tethys Sea.
- These sediments were subjected to powerful compression due to the northward movement of the Indian Plate.
- This resulted in the folding of sediments.
- Once the Indian plate started plunging below the Eurasian plate, these sediments were further folded and raised.
- And the folded sediments, after a lot of erosional activity, appear as the present-day Himalayas.
