Amasia – The Third Supercontinent in Earth’s History

A recent study has proposed that the Americas are likely to remain in the ‘ring of fire’ girdle of the post-Pangaean subduction. This will result in the Arctic Ocean and Caribbean Sea becoming enclosed. In this scenario, the supercontinent Amasia would form over the Arctic, 90 degrees away from the original Pangea.

According to new research, the next supercontinent will form between 50 million and 200 million years from now, over the North Pole. The next supercontinent would be 90 degrees away from the existing one, and it will be centered on Greenland. According to this new study, Earth will be much warmer than it is now, which could lead to a change in climate.

The center of each supercontinent should be located about 90 degrees from its predecessor, according to analyses by geologists at Yale University. They say this is in line with the current pattern of supercontinent formation. For example, they suggest that the next supercontinent should form 90 degrees away from Pangaea, over the Arctic.

The new study is based on computer simulations that model the evolution of Earth’s tectonic plates. The authors assume that the Atlantic and Pacific oceans will eventually close, leaving a rift separating Eurasia from the Indian subcontinent to the Arctic. This rift would be the result of tectonic movements over hundreds of millions of years.

Eventually, the Earth’s tectonic plates will merge, creating a new supercontinent, Amasia. This new continent will span most of the Northern Hemisphere. During this process, the Caribbean Sea and Arctic Ocean will disappear. The western edge of South America will cling to the eastern seaboard, while Australia will slam into southeastern Asia. The fate of Antarctica is uncertain.

Researchers from Curtin University simulated the formation of supercontinents by using a supercomputer. They found that the supercontinents formed when the upper layer of the ocean’s crust weakened. This process is called extroversion. It is possible that Amasia will form when the Pacific Ocean closes, but the future of this supercontinent is uncertain.

According to the theory, the next supercontinent will form where Pangaea splits, on the other side of the globe. This new supercontinent will form along the subduction girdle surrounding the previous supercontinent. This will have implications for the Earth’s climate and ecosystem.

The hypothesis is that Pangaea, Amasia, and Columbia were once supercontinents. Eventually, the supercontinents broke apart to form the continents. The first was Columbia (Nuna), which broke apart about 1.8 billion years ago, followed by Rodinia. Its sister supercontinent, Pangaea, came together 300 million years later.


Scientists are trying to understand the formation of the Rodinia, Amasia, and Nuna supercontinents. The supercontinents were thought to have formed about two billion years ago, but the timescales for their creation and dissolution are unclear. Some suggest that the supercontinents broke up before they came together, while others suggest that the supercontinents came together at different times. Regardless of how the supercontinents formed, they are all thought to be related to each other.

The scientists believe that the formation of supercontinents is linked to two processes. The first is extroversion, which subdues the oceanic lithosphere around the supercontinent. The second is introversion, which initiates subduction zones along the interior and exterior ocean boundaries. The researchers studied the motions of Earth’s tectonic plates using a supercomputer simulation.

The researchers found that Laurentia and Siberia’s dikes were similar during four periods between 1.87 billion and 720 million years ago. This suggests that they may have been connected during the Nuna-Rodinia transition. They now have a better understanding of the history of the supercontinents and its evolution.

The supercontinents formed when the oceans on Earth became cold. As a result, they could not close their internal oceans. As a result, the supercontinents that formed in the future will need to pass through the external ocean. A supercontinent formed on this basis may change the face of our world. It could cause the emergence of new supercontinents and oceans, and possibly even a new world ocean.

The supercontinents that formed after the dinosaurs have dissipated are known as Pangaea, Rodinia, and Nuna. Although Pangaea is the most recent, Rodinia, Amasia, and Nuna were formed about a billion and a half years ago.

Models of supercontinent cycles predict that the next supercontinent will form where Pangaea rifted. In addition, they predict that the next supercontinent will form 90 degrees away from the previous supercontinent. This supercontinent is expected to form along a subduction girdle encircling the predecessor supercontinent. You might also like this What is Visitor Location Register?

According to scientists, this supercontinent will form a supercontinent that consists of the present-day American and Asian continents. In two hundred and thirty million years, the supercontinent will merge with the other. The supercontinent will then cover much of the Northern Hemisphere. The Arctic Ocean and the Caribbean Sea will disappear, the western edge of South America will crowd against the eastern seaboard, and Australia will crash into southeastern Asia. Scientists are not sure how this will affect the future of Antarctica.


According to researchers, the world’s continents shifted and merged to form the Nuna, Amasia and Rodinia supercontinents about 1.8 billion years ago. This supercontinent is the third in Earth’s history. The first two, Pangea and Rodinia, formed a billion million years ago and 1.8 billion years ago, respectively. According to Yale professor David A.D. Evans, the center of Amasia formed at a location now occupied by the Arctic Ocean. A newly formed mountain range will connect the two, creating a supercontinent.

The supercontinent was largely composed of three components: Baltica, Laurentia and Siberia. It was named Nuna from the Inuktitut language, meaning “lands bordering northern oceans.” Today, the Columbia region in the Pacific Northwest was once part of the supercontinent.

Researchers studied rocks collected from the site and fed them into a computer program, which was able to reconstruct the past supercontinents. They say the supercontinents were able to move in many ways. They are believed to have been separated from each other at different times. Researchers now say that there have been three supercontinents in Earth’s past, dating back 300 million years.

The new discovery of the ancient supercontinent is a puzzle piece in the puzzle of Earth’s history. Until now, researchers have been unable to pinpoint the exact location of the Nuna supercontinent. But thanks to the research, scientists can expand the theory and pinpoint where Nuna was located.

The future emergence of Amasia supercontinent is unknown, however, and scientists continue to debate the origins of the supercontinent. Some suggest the supercontinent formed from the inside, while others believe it formed from the outside. There are two theories regarding the formation of supercontinents: introversion and extroversion. The former suggests the closing of post-Pangaean oceans, whereas the latter suggests the closure of the Pacific Ocean. The Pacific Ocean is the oldest ocean on Earth, but it is shrinking at a rate of one inch a year.

The scientists posit that the Pacific Ocean will be able to close up over a period of two billion years. The oceans around the Pacific Plate are shrinking, and the interiors will become arid, and daily temperatures will be in the mid and high-ends of the thermometer. The tectonic plates in this planet will start to shrink and eventually form the Amasia supercontinent.

This supercontinent would cause dramatic changes to global paleogeography. It would result in a lower seal level, reduced biodiversity, and a high proportion of arid land in the interior. It would be similar to the current landscape of Brazil and the Americas. These changes would likely cause the continents to become landlocked.
