Question

What is supercontinent ?​

Answer 1

Answer:

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 earth scientists use a different definition, "a grouping of formerly dispersed continents", which leaves room for interpretation and is easier to apply to Precambrian times[4] although at least about 75% of the continental crust then in existence has been proposed as a limit to separate supercontinents from other groupings

Supercontinents have assembled and dispersed multiple times in the geologic past (see table). According to modern definitions, a supercontinent does not exist today;[1] the closest in existence to a supercontinent is the current Afro-Eurasian landmass, which covers approx. 57% of Earth's total land area. The supercontinent Pangaea is the collective name describing all of the continental landmasses when they were most recently near to one another. The positions of continents have been accurately determined back to the early Jurassic, shortly before the breakup of Pangaea (see animated image).[6] The earlier continent Gondwana is not considered a supercontinent under the first definition since the landmasses of Baltica, Laurentia and Siberia were separate at the time.[7]
