Map of Pangea around 250 million years ago, at the beginning of the Triassic. Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2]
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 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.
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 ...

Novopangaea or Novopangea (Greco-Latin for "New Pangaea") is a possible future supercontinent postulated by Roy Livermore in the late 1990s. It assumes closure of the Pacific , [ 1 ] docking of Australia with East Asia and North America , and northward motion of Antarctica .
