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 ...
Pangaea's large size limited the moderating effect of the global ocean; its continental climate was highly seasonal, with very hot summers and cold winters. [25] The strong contrast between the Pangea supercontinent and the global ocean triggered intense cross-equatorial monsoons, [25] sometimes referred to as the Pangean megamonsoons. [26]
The opening of the North Atlantic Ocean is a geological event that has occurred over millions of years, during which the supercontinent Pangea broke up. As modern-day Europe (Eurasian Plate) and North America (North American Plate) separated during the final breakup of Pangea in the early Cenozoic Era, [1] they formed the North Atlantic Ocean.
The first major unit of time it contained was the Cambrian period of the Paleozoic era. [6] At the time, Earth's continents were in a very different arrangement and were generally smaller than they are today. The southeastern part of the US was connected to South America and Africa and located in the polar latitudes of the southern hemisphere.
Pangea was created by the continent of Gondwanaland and the continent of Laurussia. During the Carboniferous period the two continents came together to form the supercontinent of Pangea. The mountain building events that happened at this time created the Appalachian Mountains and the Variscan Belt of Central Europe.
The Central American Seaway (also known as the Panamanic Seaway, Inter-American Seaway and Proto-Caribbean Seaway) was a body of water that once separated North America from South America. It formed during the Jurassic (200–154 Ma ) during the breakup of the supercontinent Pangaea , and closed when the Isthmus of Panama was formed by volcanic ...
Towards the end of the period, continental drift occurred which separated Pangea. At this time, polar ice was not present because of the large differences between the equator and the poles. [citation needed] A single, large landmass similar to Pangea would be expected to have extreme seasons; however, evidence offers contradictions. Evidence ...
The world at the time was dominated by the supercontinent Pangaea, which had formed due to the collision of Euramerica and Gondwana during the Carboniferous. Pangaea was surrounded by the superocean Panthalassa. The Carboniferous rainforest collapse left behind vast regions of desert within the continental interior. [10]
