They predict Africa and Australia will join the new "supercontinent" too, which will mark the next coming together of the Earth's land masses.

 

The continents are last thought to have come together 300 million years ago into a supercontinent called Pangaea.

 

Details are published in the journal Nature.

 

 An impression of the "supercontinent of Pangaea" some 300 million years ago The land masses of the Earth are constantly moving as the Earth's tectonic activity occurs. This generates areas such as the Mid-Atlantic Ridge, where Iceland has formed, and areas such as that off the coast of Japan, where one plate rides over another.

 

Geologists believe that, over billions of years, these shifting plates have driven the continents together periodically, creating the hypothesised supercontinents of Nuna 1.8 billion years ago, Rodinia a billion years ago, and then Pangaea 300 million years ago.

 

The next supercontinent has already been given the working title of Amasia, as it is expected to involve the convergence of the Americas and Asia.

You must have spent a lot of time creating such good content. I have always enjoyed writing and recently, I created an application to help bloggers such as yourself reduce writer's block. Most importantly, I do not need to spend more than an hour drafting anymore it only takes me 10 minutes to create amazing articles. It would be amazing if you could check out alistpress and tell me what you think. Your comments would be greatly appreciated. Thank you so much. Reply
