History of Earth's supercontinents

History of Earth's supercontinents

In geology, a supercontinent It is an assembly of most or all of the continental blocks or cratons of the Earth, which become a single large land mass.

Usually, this term is associated with Pangea, the last supercontinent on our planet and the first to be identified, as well as the most studied.

However, it has not been the only supercontinent in Earth's historyInstead, we have had at least five clearly identified, and another two, the first, which are hypothetical, although every day there is more evidence of their existence.

The supercontinents of the Earth They were the following ones:

  • Vaalbara
  • Ur
  • Kenorland
  • Columbia
  • Rodinia
  • Pannotia
  • Pangea

It is expected that in the future they will be developed again supercontinents, and according to theories they would be:

  • Pangea Ultima or Pangea Proxima
  • Amasia
  • Novopangea (variation of Amasia)

According to some definitions, supercontinents could also be huge land masses They do not have to be fully assembled, but would form gigantic continents without being a single land mass.

By this definition, these supercontinents would:

  • Baby
  • Atlantic
  • Euramerica
  • Gondwana
  • Laurasia
  • Euraphrasia or Afro-Eurasia
  • The Americas

The truth is that all these huge land masses they were part of a supercontinent at some point, and therefore we do not take them as such in this definition.

Below you can know all the supercontinents of the Earth, from the hypothetical Vaalbara until Pangea, ending with the three supercontinents that hypothetically will dominate the world in the next million years.

Supercontinent Vaalbara
