In about 50 to 200 million years from now, geologist are expecting that the Earth's continents are to smash into one super large continent. This suggests that the Arctic Ocean and Caribbean Sea will be among the first to disappear. Another point of view is that scientist have assumed that either the Atlantic Ocean will close up, and reverse what once separated these continents apart. The current spreading zone in the Atlantic would push the land forms 180 degrees around the world to close up the Pacific instead. The model is based on the magnetism of ancient rocks. A doctoral student at Yale, Mitchell, took the project with other students, to record the orientation of Earth's continental plates. Also how they have changed with respect to the magnetic poles over billions of years.
