Americas, Asia will join to form a supercontinent: Amasia

As next supercontinent forms, Arctic Ocean, Caribbean will vanish first

Geologists at Yale University have proposed a new theory to describe the formation of supercontinents, the epic process by which Earth’s major continental blocks combine into a single vast landmass. The new model radically challenges the dominant theories of how supercontinents might take shape.

In a paper published Feb. 9 in the journal Nature, Yale researchers introduce a process called orthoversion, in which each succeeding supercontinent forms 90 degrees from the geographic center of its ancient predecessor. Under the theory, the present-day Arctic Ocean and Caribbean Sea will vanish as North and South America fuse during a mutual northward migration that leads to a collision with Europe and Asia.
