Pangaea or Pangea (/ p æ n ˈ dʒ iː ə / pan-JEE-ə) [1] was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. [2] It assembled from the earlier continental units of Gondwana , Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ...
The flow of heat will be concentrated, resulting in volcanism and the flooding of large areas with basalt. Rifts will form and Pangaea Proxima will split up once more in 400 to 500 million years. Earth may thereafter experience a warming period as occurred during the Cretaceous period, which marked the split-up of the previous Pangaea ...
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 degree of certainty to which the identified landmasses can be regarded as ...
According to modern definitions, a supercontinent does not exist today; [1] the closest is the current Afro-Eurasian landmass, which covers approximately 57% of Earth's total land area. The last period in which the continental landmasses were near to one another was 336 to 175 million years ago, forming the supercontinent Pangaea .
Map of Pangaea with modern continental outlines. The supercontinent cycle is the quasi-periodic aggregation and dispersal of Earth's continental crust.There are varying opinions as to whether the amount of continental crust is increasing, decreasing, or staying about the same, but it is agreed that the Earth's crust is constantly being reconfigured.
The list includes all countries listed in the List of countries, the French overseas departments, the Spanish and Portuguese overseas regions and inhabited overseas dependencies. See List of extinct countries, empires, etc. and Former countries in Europe after 1815 for articles about countries that are no longer in existence.

Euramerica in the Devonian [20] Map of Earth around 405 million years ago, during the Early Devonian, showing Euramerica (centre) and Gondwana (south and east) Laurentia remained almost static near the Equator throughout the early Palaeozoic, separated from Baltica by the up to 3,000 km (1,900 mi)-wide Iapetus Ocean ...
With a land area of 504,782 square kilometres (194,897 sq mi) in the Iberian peninsula, [1] Spain is the largest country in Southern Europe, the second largest country in Western Europe (behind France), and the fourth largest country in the European continent (behind Russia, Ukraine, and France). It has an average altitude of 650 m.
