The Pacific Plate began forming when the triple junction at the center of Panthalassa destabilized about 190 million years ago. Panthalassa , also known as the Panthalassic Ocean or Panthalassan Ocean (from Greek πᾶν "all" and θάλασσα "sea"), [ 1 ] was the vast superocean that encompassed planet Earth and surrounded the ...
Pangaea was C-shaped, with the bulk of its mass stretching between Earth's northern and southern polar regions and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists.
Oimyakon Ocean, the northernmost part of the Mesozoic Panthalassa Ocean; Paleo-Tethys Ocean, the ocean between Gondwana and the Hunic terranes; Pan-African Ocean, the ocean that surrounded the Pannotia supercontinent; Panthalassa, the vast world ocean that surrounded the Pangaea supercontinent, also referred to as the Paleo-Pacific Ocean
Map of the Panthalassic ocean c. 180 million years ago, showing the position of the Farallon plate. The Farallon plate was an ancient oceanic tectonic plate.It formed one of the three main plates of Panthalassa, alongside the Izanagi plate and the Phoenix plate, which were connected by a triple junction.
However, supercontinent cycles and Wilson cycles were both involved in the creation of Pangaea and Rodinia. [ 6 ] Secular trends such as carbonatites , granulites , eclogites , and greenstone belt deformation events are all possible indicators of Precambrian supercontinent cyclicity, although the Protopangea–Paleopangea solution implies that ...
At its beginning, all landmasses came together to form the supercontinent Pangaea, surrounded by one expansive ocean called Panthalassa. The Earth was relatively dry compared to the Carboniferous, with harsh seasons , as the climate of the interior of Pangaea was not moderated by large bodies of water.
Palaeogeographical evidence contributed to the development of continental drift theory, and continues to inform current plate tectonic theories, yielding information about the shape and latitudinal location of supercontinents such as Pangaea and ancient oceans such as Panthalassa, thus enabling reconstruction of prehistoric continents and oceans.
The word Asia originated from the Ancient Greek word Ἀσία, [9] first attributed to Herodotus (about 440 BCE) in reference to Anatolia or to the Persian Empire, in contrast to Greece and Egypt. It originally was just a name for the east bank of the Aegean Sea , an area known to the Hittites as Assuwa .
