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.
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 ...

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.
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.
The estimated time until the red dwarf star Proxima Centauri, the closest star to the Sun today, at a distance of 4.25 light-years, leaves the main sequence and becomes a white dwarf. [134] 10 13 (10 trillion) The estimated time of peak habitability in the universe, unless habitability around low-mass stars is suppressed. [135] 1.2×10 13 (12 ...
"Two hundred million years ago, our planet looked very different from what it does today. It was entirely covered by sea, which surrounded one single supercontinent we call Pangaea. And then, Pangaea began to break up. Life was cast adrift on fragments of land, and these fragments eventually became our seven continents.
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 Hercynian/Variscan orogeny in the early Carboniferous (340 Mya).
