According to one reconstruction, [29] when Rodinia broke up, it split into three pieces: proto-Laurasia, proto-Gondwana, and the smaller Congo Craton. Proto-Laurasia and proto-Gondwana were separated by the Proto-Tethys Ocean. Proto-Laurasia split apart to form the continents of Laurentia, Siberia, and Baltica. Baltica moved to the east of ...
Laurasia became North America and Eurasia, while Gondwana split into South America, Africa, Australia, Antarctica and the Indian subcontinent, which collided with the Asian plate. This impact gave rise to the Himalayas. The Tethys Sea, which had separated the northern continents from Africa and India, began to close up, forming the ...
The African and European mainlands are non-contiguous, and the delineation between these continents is thus merely a question of which islands are to be associated with which continent. The Portuguese Atlantic island possession of the Azores is 1,368 km (850 mi) from Europe and 1,507 km (936 mi) from Africa, and is sometimes grouped with Europe.
Also described as a supercraton or just a continent [13] Ur: 2,803–2,408: Mesoarchean-Siderian: Described as both a continent [2] and a supercontinent [14] Kenorland: 2,720–2,114: Neoarchean-Rhyacian: Alternatively the continents may have formed into two groupings Superia and Sclavia [15] [4] Arctica: 2,114–1,995: Rhyacian-Orosirian
Apparently, Pangea broke apart at about the speed fingernails grow.
The continent of Gondwana was named by the Austrian scientist Eduard Suess, after the region in central India of the same name, which is derived from Sanskrit for "forest of the Gonds". [6] The name had been previously used in a geological context, first by H. B. Medlicott in 1872, [ 7 ] from which the Gondwana sedimentary sequences ( Permian ...
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]
The continents now known as Africa and South America started to split around 140 million years ago, researchers said. The south Atlantic Ocean eventually filled the void.
