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 ...
Between ~825 and 750 Ma Rodinia broke apart. [9] However, before completely breaking up, some fragments of Rodinia had already come together to form Gondwana by ~608 Ma. Pangaea formed through the collision of Gondwana, Laurasia (Laurentia and Baltica), and Siberia.
Rodinia (from the Russian родина, rodina, meaning "motherland, birthplace" [1] [2] [3]) was a Mesoproterozoic and Neoproterozoic supercontinent that assembled 1.26–0.90 billion years ago (Ga) [4] and broke up 750–633 million years ago (Ma). [5]
Apparently, Pangea broke apart at about the speed fingernails grow. ... Over tens of millions of years, as the familiar story goes, these giant hunks of rock slowly split apart, breaking up at a ...
Pangea broke apart after 70 million years. The supercontinent was torn apart through fragmentation, which is where parts of the main landmass would break off in stages. There were two main events that led to the dispersal of Pangea. The first was a passive rifting event that occurred in the Triassic period.
The opening of the North Atlantic Ocean is a geological event that has occurred over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe (Eurasian Plate) and North America (North American Plate) separated during the final breakup of Pangea in the early Cenozoic Era, [1] they formed the North Atlantic Ocean.
It separated from Gondwana (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split and finally broke apart with the opening of the North Atlantic Ocean c. 56 Mya. The name is a portmanteau of Laurentia and Eurasia. [2]
It was accompanied by huge volcanic eruptions that occurred as the supercontinent Pangaea began to break apart about 202 to 191 million years ago (40Ar/39Ar dates), [69] forming the Central Atlantic Magmatic Province (CAMP), [70] one of the largest known inland volcanic events since the planet had first cooled and stabilized.
