Explanation:

1. Pangea existed about 320 - 195 million years ago as a super - continent.
2. The ocean surrounding Pangea was Panthalassa.
3. Evidence for Pangea includes similar coal deposits on separated continents, puzzle - like fit of continents, matching mountain chains on separated continents, magnetic mineral alignments showing plate movement, and identical plant fossils on separated continents.
4. Pangea started to break up about 200 - 170 million years ago. Gondwana broke up about 150 million years ago and Laurasia about 60 million years ago.
5. The Central Atlantic Ocean formed as Pangea broke apart.
6. The interior of Pangea had an extremely seasonal climate.
