The tectonic plate movement will make the continent of the planet about 200 or 250 million years.
Within 200 or 250 million years, today's planet will be quite different, since all continents of today are gathered in a new "supercontinent". Researchers at Mattias Green (Bangor University, United Kingdom) and Hannah Sophia Davies and Joao C. Duarte (University of Lisbon, Portugal) discuss what this process would be in The Conversation.
From the beginning, experts have explained that the tectonic plates that make up the Earth's crust are continuously moving, moving at a low centimeter speed. This means that from time to time, in geological terms, the continents gather in a supercontinent, that is, they spend hundreds of millions of years to distribute again.
The last supercontinent, Pangea, was founded 310 million years ago and began to differentiate some 180 million years ago. The next one is expected to be generated around 200 or 250 million years. The Pangea fracture formed the Atlantic Ocean, which is still expanding and extending, while closing the Pacific Ocean and reducing it. The authors of the article also recall that the Pacific is the site of an array of ring rings, on the banks (Fire Ring), the Atlantic has two.
According to the researchers, there are four basic scenarios for the creation of the next supercontinent: Novopangea, Pangea Ultima, Aurica and Amasia.
If current conditions are maintained – with the Atlantic opening and the Pacific going down – the next supercontinent will be opposed to the old Pangea, experts say. America will hit Antarctica, going north, and then, together with Africa and Eurasia, to create Novopangea.
If the Atlantic expansion is slowed down and shut down, the small rocks of subductories could be spread over the east coast of America, for Pangea recreation. In America, Europe and Africa they would meet again in a supercontinent called Pangea Ultima, surrounded by the Pacific superiors.
On the other hand, although the new footprint areas appeared in the Atlantic Ocean, the oceans could be closed, one of which was replaced by a sea basin.
In the end, the fourth stage takes on a "completely different destiny of the Earth of the future," according to the researchers. In this regard, they emphasized that some tectonic plaques, including Africa and Australia, are now moving northwards, driven by anomalies left by the Earth's mantle Pangea. So, all continents, except Antarctica, can imagine a scenario that continues to move on the north in a supercontinent that has given hypothetical names to Amas.
What scenario is it likely?
Scientists believe Novopangea is a serious situation, because the current trend is logical progression, and the other three cases involve the involvement of complementary processes.
