WILL MARK AS BRAINLIST FOR GOOD EXPLANATION PLEASE HELP :( Q: Write a comprehensive note on the importance of ocean ​

tethys sea was an ocean during the mesozoic era .

this ocean was found between gondwana and laurasia.

the name of the ocean came from tethys the titan goddess of the primal font of fresh water which nourishes the earth.

the ocean was also know as neotethys.

the correct answer is - end permian.

the end of the permian was marked by the biggest mass extinction out planet had ever witnessed, so no wander that this period has been given the nickname of ''the great dying''. around 96% of the species died out, and it was caused by multiple natural catastrophes, including massive super volcano explosions and lava flows, huge amounts of co2 released into the atmosphere, as well as methane from the algae, and that contributed to acidified and stagnant oceans. it is thought that it set life on earth backwards for about 300 million years.
