Eurasia is considered a supercontinent, part of the supercontinent of Afro-Eurasia or simply a continent in its own right. [7] In plate tectonics, the Eurasian Plate includes Europe and most of Asia but not the Indian subcontinent, the Arabian Peninsula or the area of the Russian Far East east of the Chersky Range.
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 African and European mainlands are non-contiguous, and the delineation between these continents is thus merely a question of which islands are to be associated with which continent.
Map of Pangaea with modern continental outlines.

Etymology From the 16th century the English noun continent was derived from the term continent land , meaning continuous or connected land [ 5 ] and translated from the Latin terra continens . [ 6 ]

Eduard Suess had proposed a supercontinent Gondwana in 1885 [15] and the Tethys Ocean in 1893, [16] assuming a land-bridge between the present continents submerged in the form of a geosyncline, and John Perry had written an 1895 paper proposing that the Earth's interior was fluid, and disagreeing with Lord Kelvin on the age of the Earth.
