Answer 2

The northern continental group formed million years ago is Pangaea.

• Pangaea was accumulated from mainland obstructs that contrasted from the present landmasses.
• Pangaea was encircled by a widespread sea called Panthalassa, which was the precursor of the present Pacific Ocean. The Atlantic Ocean didn't exist even in hereditary structure, as a result of the combinations of North America to Europe and South America to Africa.
• Around 190 million years prior, Pangaea started to separate into Gondwanaland and Laurasia. Northern Africa and South America stayed central, though North America and Europe moved poleward.
