Answer to Question 1

The Atlantic Ocean basin was created through the breakup of Pangea.

Answer to Question 2

In North America, the Baja Peninsula and the portion of Southern California that lies west of the San Andreas Fault will have slid past the North American plate. If Africa continues to collide with Eurasia, the result will be the closing the Mediterranean. Australia will be astride the equator and, along with New Guinea, will be on a collision course with Asia. Meanwhile, North and South America will begin to separate, while the Atlantic and Indian Oceans continue to grow at the expense of the Pacific Ocean.
