The new supercontinent “Amasia” will form in 200 million years, the Pacific Ocean will close – Simulation shows
In a computer simulation, a research team predicted that in 200 million years, all the continents of the world will merge into a single new supercontinent called “Amasia”. According to new research from Curtin University, Amasia is most likely to form when the Pacific Ocean, the oldest of the oceans, closes in 200 to 300 million years.
Using a supercomputer, the team simulated the formation of a supercontinent and discovered that since the Earth has been cooling for billions of years, the resistance and thickness of the plates under the oceans have decreased over the years. over time. This makes it more difficult for the next supercontinent to form by sealing off “young” oceans, such as the Atlantic or Indian oceans.
The new findings, according to the study’s lead author, Dr Chuan Huang of the Earth Dynamics Research Group and Curtin School of Earth and Planetary Sciences, were significant and offered new information about what would happen to Earth over the next 200 million years.
The supercontinent cycle, which has occurred over the past 2 billion years as a result of the collision of Earth’s continents, was described by Huang. This indicates that the current continents will probably come together in a few hundred million years.
Because some people think that when America collides with Asia, the Pacific Ocean will close instead of the Atlantic and Indian Oceans. This will result in a new supercontinent which has already been given the name Amasia. Australia is also expected to play a role in this significant land event, initially colliding with Asia before connecting America and Asia after the Pacific Ocean closes.

The Pacific Ocean is shrinking and will close
The team was able to disprove some previous scientific theories by simulating the predicted evolution of Earth’s tectonic plates using a supercomputer, and they were able to demonstrate that in less than 300 million years it is likely that the Pacific Ocean will close, allowing the formation of Amasia.
The Panthalassa Super Ocean, which began forming 700 million years ago when the ancient supercontinent began to disintegrate, is now just the Pacific Ocean. It is the oldest ocean on Earth, having shrunk in total size since the age of the dinosaurs. Its size is currently shrinking by a few centimeters every year, and it will take between 200 and 300 million years to get closer to its current size of about 10,000 kilometers.
Earth’s ecosystem and environment would be significantly altered if a landmass dominated the entire planet, according to study co-author and John Curtin professor Zheng-Xiang Li, who is also a member of Curtin’s School of Science. Earth and Planetary Sciences.
Li claimed that when Amasia emerges, Earth will be drastically changed. Sea levels are expected to be lower, and the vast interior of the supercontinent is expected to be extremely arid with large daily temperature swings.
Li is intrigued to see what the planet might look like in about 200 to 300 million years, as Earth currently has seven continents with extremely diverse ecosystems and human cultures, reports Phys Org.
