Answer 1

Around 200 million years ago Pangaea rifted and seafloor spreading along the Mid‑Atlantic Ridge—separating North/South America from Eurasia/Africa (and nearby smaller plates)—opened the Atlantic, creating a new ocean basin with a mid‑ocean ridge and passive continental margins, shifting continents and changing ocean circulation, climate, and habitats.
