The supercontinent cycle is the quasi-periodic aggregation and dispersal of Earth's continental crust. There are varying opinions as to whether the amount of continental crust is increasing, decreasing, or staying about the same, but it is agreed that the Earth's crust is constantly being reconfigured.
A supercontinent cycle is the break-up of one supercontinent and the development of another, which takes place on a global scale. [4] Supercontinent cycles are not the same as the Wilson cycle, which is the opening and closing of an individual oceanic basin. The Wilson cycle rarely synchronizes with the timing of a supercontinent cycle. [1]
Pangaea Proxima (also called Pangaea Ultima, Neopangaea, and Pangaea II) is a possible future supercontinent configuration. Consistent with the supercontinent cycle, Pangaea Proxima could form within the next 250 million years.
Take the supercontinent Gondwana, for example. Some 180 million years ago, the landmass separated from what is now India, Australia, and Antarctica. 40 million years later, the south Atlantic ...
Pangaea is the most recent supercontinent reconstructed from the geologic record and therefore is by far the best understood. The formation of supercontinents and their breakup appears to be cyclical through Earth's history.
Animation of the break-up of the supercontinent Pangaea and the subsequent drift of its constituents, from the Early Triassic to recent (250 Ma to 0). This is a list of paleocontinents, significant landmasses that have been proposed to exist in the geological past. The degree of certainty to which the identified landmasses can be regarded as ...
In the future, America and Asia will collide - forming a new supercontinent called Amasia, as the Pacific Ocean closes up. The Pacific ocean is closing up - and the new supercontinent will be 'Amasia'
Researchers at Curtin University and Peking University say the Earth's continents will collide within the next 200 million to 300 million years.
