This will be Amasya, the only continent currently forming on Earth.

Research led by Curtin University (Australia) found that: the world’s next supercontinent, Amasya (short for America and Asia) will form when the Pacific Ocean closes completely, which will probably happen in 200 or 300 million years. At that time, all existing continents will merge and take shape. a single landmass.

Posted in National Science Reviewresearch team used a supercomputer to simulate how a supercontinent formed and found that as the Earth has cooled for billions of years, the thickness and strength of tectonic plates under the oceans have decreased over time, making it harder for the supercontinent to form after the “young” oceans closed. Like the Atlantic or the Indian Ocean.

Lead author Dr Chuan Huang, from Curtin’s Earth Dynamics Research Group and the School of Earth and Planetary Sciences, said the new findings are important and provide insight into what will happen to Earth in the next 200 million years.

“For the last 2 billion years, Earth’s continents have collided to form a supercontinent every 600 million years.known as the supercontinent cycle. “This means that the existing continents will rejoin in a few hundred million years,” he said.

Past and future evolution of continents Curtin University


The emerging new supercontinent is already It was named Amasya because it was believed that the Pacific Ocean would close when America collided with Asia (as opposed to the Atlantic and Indian oceans).. Australia is also expected to play a role in this major land event, first colliding with Asia as the Pacific Ocean closes and then connecting the Americas and Asia.

“By simulating how Earth’s tectonic plates are expected to evolve using a supercomputer, we were able to show that in less than 300 million years the Pacific Ocean would likely close, allowing Amasya to form, thus discrediting some previous scientific theories.” .

The Pacific Ocean is what remains of the Panthalassa superocean that began to form 700 million years ago. When the previous supercontinent began to break up, it formed the present ones. It is the oldest ocean we have on Earth and has started to shrink from its maximum size since the time of the dinosaurs. It is still shrinking by a few centimeters per year and is estimated to take 200 to 300 million years to fully close.

Continental puzzle of the future THREE


Professor Zheng-Xiang Li, also from the Curtin School of Earth and Planetary Sciences, said that the dominance of a single land mass across the world would drastically change the Earth’s ecosystem and environment.

“Earth as we know it will be drastically different when Amasia forms. Sea levels are expected to be lower, and the vast interior of the supercontinent will be very arid with high diurnal temperature ranges.”said Professor Li.

“Earth right now consists of seven continents with very different ecosystems and human cultures, so it would be fascinating to think about what the world will look like 200 to 300 million years from now.”
