Researchers have predicted that a new megacontinent – Amasia – will form in the next 250 million years.
North and South America will crunch together, with the Caribbean Sea and Arctic Ocean disappearing, while Asia will join the Americas, according to new simulations from Yale University researchers and Japan’s Agency for Marine-Earth Science and Technology.
This will happen because of the movement of the earth’s tectonic plates – the enormous plates of the earth’s crust that have drifted together and apart over hundreds and millions of years.
The research, published in the journal Nature, is based on a theory called Orthoversion – after a supercontinent breaks up, the continents initially drift apart but become trapped within a north–south band of subduction – where one plate dips below another.
On our present-day Earth this band is the Pacific Ring of Fire, where the new supercontinent will form.
