The correct answer is it led to the formation of one global supercontinent.
What is not true about the rift that developed between the eastern United States and western Africa some 200 million years ago is “is it led to the formation of one global supercontinent.”
Pangea is the only a supercontinent that incorporated all the landmasses on Earth at the beginning of geologic time. In 1912, German meteorologist Alfred Wegener named this supercontinent in his theory of continental drift. This supercontinent was surrounded by an immense ocean. The scientist named this ocean as Panthalassa. We are talking about 200 to 300 million years ago. Research studies affirm that Pangea started to separate in the early Jurassic time, to begin with the formation of the continents as we know now. and the Atlantic and Indian oceans. Pangea’s existence was first proposed.
