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 ...
The cause for the extinction is disputed, but a likely candidate is an episode of global cooling, which transformed a large amount of sea-water into continental ice. [14] Seamounts accreted in eastern Australia as parts of the New England orogen reveal the hotspot history of Panthalassa. [15]
Pangea was created by the continent of Gondwanaland and the continent of Laurussia. During the Carboniferous period the two continents came together to form the supercontinent of Pangea. The mountain building events that happened at this time created the Appalachian Mountains and the Variscan Belt of Central Europe.
Before it split into the continents we know today, Earth was home to just a single landmass, or "supercontinent," called Pangea. Over tens of millions of years, as the familiar story goes, these ...
Laurasia (/ l ɔː ˈ r eɪ ʒ ə,-ʃ i ə /) [1] was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around , the other being Gondwana. It separated from Gondwana 215 to 175 Mya (beginning in the late Triassic period) during the breakup of Pangaea, drifting farther north after the split and finally ...
Pangaea was formed by the convergence of multiple continental masses and later broke apart to form two primary continents, Laurasia and Gondwana As the Jurassic (201–145 Ma) started, Pangaea began to break up into two continents , Gondwana and Laurasia , marking the beginning of the separation of Scotland and North America.
First phase of the Tethys Ocean's forming: the (first) Tethys Sea starts dividing Pangaea into two supercontinents, Laurasia and Gondwana.. The Tethys Ocean (/ ˈ t iː θ ɪ s, ˈ t ɛ-/ TEETH-iss, TETH-; Greek: Τηθύς Tēthús), also called the Tethys Sea or the Neo-Tethys, was a prehistoric ocean during much of the Mesozoic Era and early-mid Cenozoic Era.
The Rheic Ocean formed behind it, and the Iapetus Ocean shrank in front. It collided with the continents Baltica, then Laurentia, and finally with Gondwana, ending up in the interior of Pangea. When Pangea broke up, Avalonia's remains were divided by the rift which became the Atlantic Ocean.
