what happen in Tethys sea due to the movement of India towards north
Answers
Answer:
Ans- Tethys Sea, former tropical body of salt 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). Laurasia consisted of what are now North America and the portion of Eurasia north of the Alpine-Himalayan mountain ranges, while Gondwana consisted of present-day South America, Africa, peninsular India, Australia, Antarctica, and those Eurasian regions south of the Alpine-Himalayan chain. These mountains were created by continental collisions that eventually eliminated the sea. Tethys was named in 1893, by the Austrian geologist Eduard Suess, after the sister and consort of Oceanus, the ancient Greek god of the ocean.

Mesozoic Era
At least two Tethyan seas successively occupied the area between Laurasia and Gondwana during the Mesozoic Era. The first, called the Paleo (Old) Tethys Sea, was created when all landmasses converged to form the supercontinent of Pangea about 320 million years ago, late in the Paleozoic Era. During the Permian and Triassic periods (approximately 300 to 200 million years ago), Paleo Tethys formed an eastward-opening oceanic embayment of Pangea in what is now the Mediterranean region. This ocean was eliminated when a strip of continental material (known as the Cimmerian continent) detached from northern Gondwana and rotated northward, eventually colliding with the southern margin of Laurasia during the Early Jurassic Epoch (some 180 million years ago). Evidence of the Paleo Tethys Sea is preserved in marine sediments now incorporated into mountain ranges that stretch from northern Turkey through Transcaucasia (the Caucasus and the Pamirs), northern Iran and Afghanistan, northern Tibet (Kunlun Mountains), and China and Indochina.
