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.
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.
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 Proxima (also called Pangaea Ultima, Neopangaea, and Pangaea II) is a possible future supercontinent configuration. Consistent with the supercontinent cycle , Pangaea Proxima could form within the next 250 million years.
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 ...

[4] Frndly TV has a channel lineup with a focus on family-friendly programming, [5] and includes U.S. networks Hallmark Channel, [6] The Weather Channel, A&E, History, Lifetime, MeTV, Story Television, and Up TV.
In Mexico it was first available on Televisa's Cablevisión cable TV system in March 1996 followed by its launch in Brazil that same year. Unlike most television networks in Latin America, which air all imported shows dubbed in Spanish or Portuguese, Sony started airing its programming with subtitles, which led to its role as a regional TV leader.
The supercontinent Columbia about 1.6 billion years ago. Columbia, also known as Nuna or Hudsonland, is a hypothetical ancient supercontinent.It was first proposed by John J.W. Rogers and M. Santosh in 2002 [1] and is thought to have existed approximately (Ma), in the Paleoproterozoic era.
