According to the Pangaea Proxima hypothesis, the Atlantic and Indian Oceans will continue to get wider until new subduction zones bring the continents back together, forming a future Pangaea. Most continents and microcontinents are predicted to collide with Eurasia , just as they did when most continents collided with Laurentia .
Pangaea's supercontinent cycle is a good example of the efficiency of using the presence or lack of these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.
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.
According to the extroversion model first developed by Paul F. Hoffman, subduction ceases in the Pacific Ocean Basin. [71] [77] 400–500 million The supercontinent (Pangaea Proxima, Novopangaea, Amasia, or Aurica) will likely have rifted apart. [71] This will likely result in higher global temperatures, similar to the Cretaceous period. [73]
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] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
It is one of the four proposed supercontinents that are speculated to form within 200 million years, the others being Pangaea Proxima, Amasia, and Novopangaea. The Aurica hypothesis was created by scholars at the Geological Magazine [ 1 ] following an American Geophysical Union study linking the strength of ocean tides to the supercontinent ...
The Wilson cycle theory is based upon the idea of an ongoing cycle of ocean closure, continental collision, and a formation of new ocean on the former suture zone.The Wilson Cycle can be described in six phases of tectonic plate motion: the separation of a continent (continental rift), formation of a young ocean at the seafloor, formation of ocean basins during continental drift, initiation of ...
Pangaea formed during the closure of the Rheic Ocean 330 Mya (early Carboniferous) (view centred on 30°S,30°E) The subduction of the Iapetus Ocean resulted in the first contact between Laurussia and Gondwana in the Late Devonian and terminated in full collision or the Variscan orogeny in the early Carboniferous (340 Mya).
