In paleogeography, Laurasia (pron.: /lÉËËreÉªÊÉ/ or /lÉËËreÉªÊiÉ/) was the northernmost of two supercontinents (the other being Gondwana) that formed part of the Pangaea supercontinent from approximately 300 to 200 million years ago (Mya). It separated from Gondwana 200 to 180 Mya (the late Triassic era) during the breakup of Pangaea, drifting further north after the split.
Based on how the tectonic plates are moving now, no later than one hundred million years, Asia and the Americas will merge into one huge supercontinent, named Amasia. Geophysicists have long theoretized this, but a team of researchers from Yale University offered a new view on how Amasia will be formed. Continental drift Continental drift [...]
