I want to know the answer to the following question:
When did the single tectonic plate break into separate plates?
All the background I'm provided with is that "In the Paleozoic Era the Pangaean supercontinent consisted of a single tectonic plate; it broke into separate plates during the Mesozoic Era and the Tethys sea developed between Laurasia and Gondwana during the Jurassic Period.". Is that enough to answer the question?
Answer: yes
