Amasia

Three possible scenarios for Amasia. The canonical scenario would look like the one on the left.

Amasia is a possible future supercontinent which could be formed by the merger of Asia, Australia and the Americas. The prediction relies mostly on the fact that the Pacific plate is already subducting under Eurasia and the Americas, a process which if continued will eventually cause the Pacific to close. Meanwhile, because of the Atlantic mid-ocean ridge, North America would be pushed westward. Thus, the Atlantic at some point in the future would be larger than the Pacific Ocean. In Siberia, the boundary between the Eurasian and North/South American plates has been stationary for millions of years. The combination of these factors would cause the Americas to be combined with Asia, thus forming a supercontinent.
