It is part of the natural cycle, scientists say, where tectonic plates congregate in a supercontinent, which then decays again.
The last time was the supercontinent known as Pangea, formed about 310 million years ago, before it collapsed about 180 million years ago.

The future continent may have several forms: Novopangya, Pangea Ultima, Aurica and Amassia.
In Amassia's scenario, for example, the clash will see the merger of North and South America – and the Arctic Ocean disappears while Asia joins America, all caused by the movement of "tectonic plates" on Earth.
The researchers say they believe Novopangya is most likely.
The researchers write: "If we assume that the current conditions continue, so that the Atlantic continues to open and the Pacific continues to close, we have a scenario where the next supercontinent is formed in the Pangea counterparts.
"America will clash with the northern Antarctic that flies, and then in already clashing with Africa-Eurasia.
"Supercontinent, which will then be formed, is called Novopangya, or Novopangya.
