As for how these movements will affect North America, geologists theorize that the north shore of South America will slide onto the Gulf Coast of the United States. The Gulf Coast shoreline will disappear and the Caribbean will be squeezed out of existence. Likewise, the mass of Eurasia will compress the Atlantic out of being and the Eurasian and American super-masses will slide toward a polar rendezvous. The future, in short, may look a lot like the last 600 million years of Earth's geological history, only in reverse.
However the continents finally align themselves though, it is likely that our beautiful planet will still look like a big blue marble floating in space.
