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]
Dicroidium zuberi, an Early Triassic plant from Pangaea (present-day Argentina) The four floristic provinces of the world at the Permian-Carboniferous boundary, 300 million years ago. Pangaea existed as a supercontinent for 160 million years, from its assembly around 335 Ma (Early Carboniferous) to its breakup 175 Ma (Middle Jurassic). [3]
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 formation of a new “supercontinent” could wipe out humans and all other mammals still alive in 250 million years, researchers have predicted.
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 ...
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 ...
Supercomputer simulations predicted the climatic consequences of Earth's potential supercontinent formation, which could pose a threat to human survival. A Simulation Says Earth Will Turn Into One ...
