Little is known about the paleogeography before the formation of Rodinia. Paleomagnetic and geologic data are only definite enough to form reconstructions from the breakup of Rodinia [17] onwards. Rodinia is considered to have formed between 1.3 and 1.23 Ga and broke up again before 750 Ma. [18] Rodinia was surrounded by the superocean Mirovia.
Pangaea's supercontinent cycle is a good example of the efficiency of using the presence or lack of these entities to record the development, tenure, and break-up of supercontinents. There is a sharp decrease in passive margins between 500 and 350 Ma during the timing of Pangaea's assembly.
The continents that had drifted away from Rodinia drifted together again during the Paleozoic: Gondwana, Euramerica, and Siberia/Angara collided to form the supercontinent of Pangea during the Devonian and Carboniferous periods, some 350 million years ago. Pangea was a short-lived supercontinent; it began to break apart again in the early ...
The phrase was originally said by Captain James T. Kirk (William Shatner) in the original Star Trek series. "Where no man has gone before" is a phrase made popular through its use in the title sequence of the original 1966–1969 Star Trek science fiction television series, describing the mission of the starship Enterprise.
The supercontinent Rodinia began to break up 870–845 Ma probably as a consequence of a superplume caused by mantle slab avalanches along the margins of the supercontinent. In a second episode c. 750 Ma the western half of Rodinia started to rift apart: western Kalahari and South China broke away from the western margins of Laurentia ; and by ...
The Star Trek Star Charts have the Romulans and Klingons entirely within the Beta Quadrant, as well as the Gorn Hegemony, the Son'a Solidarity, and the Metron Consortium. The Star Trek Star Charts further locate in the Alpha Quadrant the First Federation, Breen, Ferengi, Tzenkethi, Cardassians, Bajorans, Talarians, and Tholians.
Notable Star Trek races include Vulcans, Klingons, and the Borg. [1] Some aspects of these fictional races became well known in American pop culture, such as the Vulcan salute and the Borg phrase, "Resistance is futile." Star Trek aliens have been featured in Time magazine, which described how they are essential to the franchise's narrative. [1
Laurasia and Gondwana were equal in size but had distinct geological histories. Gondwana was assembled before the formation of Pangaea, but the assembly of Laurasia occurred during and after the formation of the supercontinent. These differences resulted in different patterns of basin formation and transport of sediments.
