LaurentiaLaurentia or the North American Craton is a large continental craton that forms the ancient geological core of North America. Many times in its past, Laurentia has been a separate continent, as it is now in the form of North America, although originally it also included the cratonic areas of Greenland and also the northwestern part of Scotland, known as the Hebridean Terrane. During other times in its past, Laurentia has been part of larger continents and supercontinents and itself consists of many smaller terranes assembled on a network of Early Proterozoic orogenic belts.
SocotraSocotra (səˈkoʊtrə,_soʊ-,_ˈsɒkətrə; سُقُطْرَىٰ Suquṭrā) or Saqatri (Soqotri: ساقطري Saqaṭri) is an island of the Republic of Yemen in the Indian Ocean. Lying between the Guardafui Channel and the Arabian Sea and near major shipping routes, Socotra is the largest of the four islands in the Socotra archipelago. Since 2013, the archipelago has constituted the Socotra Governorate. The island of Socotra represents around 95% of the landmass of the Socotra archipelago.
Old WorldThe "Old World" (Mundus Vetus) is a term for Afro-Eurasia that originated in Europe 1596, after Europeans became aware of the existence of the Americas. It is used to contrast the continents of Africa, Europe, and Asia, which were previously thought of by their inhabitants as comprising the entire world, with the "New World", a term for the newly encountered lands of the Western Hemisphere, particularly the Americas.
Isthmus of PanamaThe Isthmus of Panama (Istmo de Panamá), also historically known as the Isthmus of Darien (Istmo de Darién), is the narrow strip of land that lies between the Caribbean Sea and the Pacific Ocean, linking North and South America. It contains the country of Panama and the Panama Canal. Like many isthmuses, it is a location of great geopolitical and strategic importance. The isthmus is thought to have been finally formed around 3 million years ago (Ma), separating the Atlantic and Pacific Oceans and causing the creation of the Gulf Stream, as first suggested in 1910 by Henry Fairfield Osborn.
Southern HemisphereThe Southern Hemisphere is the half (hemisphere) of Earth that is south of the Equator. It contains all or parts of five continents (the whole of Antarctica, the whole of Australia, about 90% of South America, about one-third of Africa, and some islands off the continental mainland of Asia) and four oceans (the whole Southern Ocean, the majority of the Indian Ocean, the South Atlantic Ocean, and the South Pacific Ocean), as well as New Zealand and most of the Pacific Islands in Oceania. Its surface is 80.
Continental collisionIn geology, continental collision is a phenomenon of plate tectonics that occurs at convergent boundaries. Continental collision is a variation on the fundamental process of subduction, whereby the subduction zone is destroyed, mountains produced, and two continents sutured together. Continental collision is only known to occur on Earth. Continental collision is not an instantaneous event, but may take several tens of millions of years before the faulting and folding caused by collisions stops.
LaurasiaLaurasia (lɔːˈreɪʒə,_-ʃiə) was the more northern of two large landmasses that formed part of the Pangaea supercontinent from around (Mya), the other being Gondwana. 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 Asia. Laurentia, Avalonia, Baltica, and a series of smaller terranes, collided in the Caledonian orogeny c.
OrientThe Orient is a term for the East in relation to Europe, traditionally comprising anything belonging to the Eastern world. It is the antonym of Occident, the Western World. In English, it is largely a metonym for, and coterminous with, the continent of Asia, loosely classified into the Southwest Asia, Southeast Asia, South Asia, Central Asia, East Asia, and sometimes including the Caucasus. Originally, the term Orient was used to designate only the Near East, and later its meaning evolved and expanded, designating also Central Asia, Southwest Asia, South Asia, Southeast Asia, or the Far East.
Continental shelfA continental shelf is a portion of a continent that is submerged under an area of relatively shallow water, known as a shelf sea. Much of these shelves were exposed by drops in sea level during glacial periods. The shelf surrounding an island is known as an insular shelf. The continental margin, between the continental shelf and the abyssal plain, comprises a steep continental slope, surrounded by the flatter continental rise, in which sediment from the continent above cascades down the slope and accumulates as a pile of sediment at the base of the slope.
JaphethJapheth ˈdʒeɪfɛθ (יֶפֶת Yép̄eṯ, in pausa Yā́p̄eṯ; Ἰάφεθ ; Iafeth, Iapheth, Iaphethus, Iapetus) is one of the three sons of Noah in the Book of Genesis, in which he plays a role in the story of Noah's drunkenness and the curse of Ham, and subsequently in the Table of Nations as the ancestor of the peoples of the Aegean Sea, Anatolia, and elsewhere. In medieval and early modern European tradition he was considered to be the progenitor of the European peoples, while Islamic traditions also include the Chinese people among his descendants.
