A supercontinent cycle is the break-up of one supercontinent and the development of another, which takes place on a global scale. [4] Supercontinent cycles are not the same as the Wilson cycle, which is the opening and closing of an individual oceanic basin. The Wilson cycle rarely synchronizes with the timing of a supercontinent cycle. [1]
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. The assembly of the supercontinent was likely ...
Wegener used the name "Pangaea" once in the 1920 edition of his book, referring to the ancient supercontinent as "the Pangaea of the Carboniferous". [12] He used the Germanized form Pangäa , but the name entered German and English scientific literature (in 1922 [ 13 ] and 1926, respectively) in the Latinized form Pangaea , especially during a ...
Amasia, 100 million years in the future [citation needed]. Amasia is a possible future supercontinent which could be formed by the merger of Asia and the Americas.The prediction relies mostly on the fact that the Pacific Plate is already subducting under Eurasia and the Americas, a process which if continued will eventually cause the Pacific to close.

Animation of the break-up of the supercontinent Pangaea and the subsequent drift of its constituents, from the Early Triassic to recent (250 Ma to 0).. This is a list of paleocontinents, significant landmasses that have been proposed to exist in the geological past.
The name had been previously used in a geological context, first by H. B. Medlicott in 1872, [7] from which the Gondwana sedimentary sequences (Permian-Triassic) are also described. Some scientists prefer the term "Gondwanaland" for the supercontinent to make a clear distinction between the region and the supercontinent.
Consistent with the supercontinent cycle, Pangaea Proxima could form within the next 250 million years. This potential configuration, hypothesized by Christopher Scotese in November 1982, earned its name from its similarity to the previous Pangaea supercontinent.
Mirovia, the ocean that surrounded the Rodinia supercontinent; Mongol-Okhotsk Ocean, the early Mesozoic ocean between the North China and Siberia cratons; Oimyakon Ocean, the northernmost part of the Mesozoic Panthalassa Ocean; Paleo-Tethys Ocean, the ocean between Gondwana and the Hunic terranes
