What is Tethys Sea Class 9?
The Tethys Ocean was the ocean which existed between the continents of Gondwana and Laurasia. These existed during much of the Mesozoic era, before the opening of the Indian and Atlantic oceans. It was during the Cretaceous period. These are also referred to as the Tethys Sea of Neotethys.
Where was the Cenozoic Tethys Sea located?
The Tethys Ocean is a well-known ocean of the Mesozoic era (between 250 and 65 million years ago) and was situated between the old continents of Gondwana and Laurasia.
What was the first ocean called?
Panthalassa
Panthalassa, also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν “all” and θάλασσα “sea”), was the superocean that surrounded the supercontinent Pangaea, the latest in a series of supercontinents in the history of Earth. During the Paleozoic–Mesozoic transition c.
When did Laurasia break up?
It separated from Gondwana 215 to 175 Mya (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split and finally broke apart with the opening of the North Atlantic Ocean c. 56 Mya.
What was the role of Tethys Sea in the formation of Himalayas?
Separating the two was the Tethys Sea. As India approached Asia, around 40 million years ago, the Tethys Sea began to shrink and its seabed slowly pushed upwards. The Tethys Sea disappeared completely around 20 million years ago and sediments rising from its seabed formed a mountain range.

What happened to the Tethys in India?
During sometime after 140 mya Indian landmass broke off from Gondwanaland and started moving towards Eurasia and ultimately slammed against it around 65 mya. The silt deposit in the Tethys gave rise to Himalayas and the sea disappeared. It is said that the Mediterranean Sea is the surviving trace of the Tethys.
What caused the Tethys to become closed off?
Throughout the Cenozoic (66 million to the dawn of the Neogene, 23 Mya), a combination of the northern migration of Africa and global sea levels falling eventually led to the connections between the Atlantic and Indian Oceans across the Tethys being closed off in what is now the Middle East during the Miocene.
