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]
Map of Pangaea with modern continental outlines. 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.
The supercontinent will be encircled by a global ocean, the Neopanthalassan Ocean (meaning "new" Panthalassan Ocean), [7] which encircles half the Earth. [9] The Earth is expected to have a hothouse climate with an average global temperature of 28 °C (82 °F). [7] The only areas likely to be habitable for land mammals are those closest to the ...
The authors wrote that, within 250 million years, all the continents will converge to form Earth’s next supercontinent: Pangea Ultima. “A natural consequence of the creation and decay of ...
The formation of a new “supercontinent” could wipe out humans and all other mammals still alive in 250 million years, researchers have predicted.
Vaalbara is a hypothetical Archean supercontinent consisting of the Kaapvaal Craton (now in eastern South Africa) and the Pilbara Craton (now in north-western Western Australia).
The supercontinent Columbia about 1.6 billion years ago. Columbia, also known as Nuna or Hudsonland, is a hypothetical ancient supercontinent. It was first proposed by John J.W. Rogers and M. Santosh in 2002 [1] and is thought to have existed approximately (Ma), in the Paleoproterozoic era. The assembly of the supercontinent was likely ...
Kenorland is a hypothetical Neoarchean supercontinent.If it existed, it would have been one of the earliest known supercontinents on Earth.It is thought to have formed during the Neoarchaean Era c. 2.72 billion years ago (2.72 Ga) by the accretion of Neoarchaean cratons and the formation of new continental crust.
