    en.wikipedia.org/wiki/Supercontinent

    In geology, a supercontinent is the assembly of most or all of Earth 's continental blocks or cratons to form a single large landmass. [1][2][3] However, some geologists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times. [4]

    The supercontinent in the early Mesozoic (at 200 Ma) surrounded by Panthalassa. The Pacific Plate began forming when the 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 ...

    Gondwana ( / ɡɒndˈwɑːnə /) [1] was a large landmass, sometimes referred to as a supercontinent. The remnants of Gondwana make up around two-thirds of today's continental area, including South America, Africa, Antarctica, Australia, Zealandia, Arabia, and the Indian Subcontinent.

    Earth subsequently underwent a series of glaciations – the Varanger (c. 650 Mya, also known as Snowball Earth) and the Rapitan and Ice Brook glaciations (c. 610-590 Mya) – both Laurentia and Baltica were located south of 30°S, with the South Pole located in eastern Baltica, and glacial deposits from this period have been found in Laurentia ...

    en.wikipedia.org/wiki/Central_Pangean_Mountains

    The Central Pangean Mountains were formed during the collision of Euramerica and northern Gondwana as part of the Variscan and Alleghanian orogenies, which began during the Carboniferous approximately 340 million years ago, and complete by the beginning of the Permian around 295 million years ago, when the range was at its maximum elevation.

  9. Geological history of Earth - Wikipedia

    en.wikipedia.org/wiki/Geological_history_of_Earth

    The geological history of the Earth follows the major geological events in Earth's past based on the geological time scale, a system of chronological measurement based on the study of the planet's rock layers (stratigraphy). Earth formed about 4.54 billion years ago by accretion from the solar nebula, a disk-shaped mass of dust and gas left ...
