A new model predicts that the Pacific Ocean will disappear in 300 million years, bringing the continents together to form a new supercontinent, called Amasia, around the North Pole.
The simulation was conducted by a team of researchers led by Australia’s Curtin University, highlighting the fact that the Pacific Ocean is the oldest and started shrinking as dinosaurs roamed the Earth — currently losing a few inches a year.
The model shows Asia moving east to America, which is pulled west until the three continents meet like a perfect puzzle piece. Antarctica eventually finds its way to South America, Africa attaches itself to Asia on one side and Europe on the other to complete Amasia.
The analysis could be on point as evidence shows a new supercontinent formed every 600 million years and the last was Pangea formed 300 million years ago.
The simulation predicts that the Pacific Ocean will disappear, resulting in a continuous shift towards each other around the North Pole
The first supercontinent, believed to be Vaalbara, was formed 3.3 billion years ago and was followed by Ur 300 million years later.
However, Ur is widely accepted as the first supercontinent due to stronger evidence proving its existence – not much is known about Vaalbara.
Kenorland was next when it was formed 2.7 billion years ago and is said to be made up of smaller cratons, large stable blocks of the Earth’s crust that form the core of a continent.
And then came Columbia, which was formed by colossal collisions 1.8 billion years ago.
This supercontinent was made up of the protocratons that had previously formed Laurentia, Baltica, the Ukrainian and Amazon shields, Australia and even Siberia, northern China and Kalaharia.
Asia moves east toward America, which is pulled west until they all come together like a puzzle piece. Antarctica eventually makes its way to South America, Africa attaches itself to Asia on one side and Europe on the other to complete Amasia
When Columbia started to fall apart over the course of a few hundred million years, they reunited about a billion years ago to form Rodinia and it dominated the world for the next 350 million years.
Pannotia came next, formed about 600 million years ago, and lasted about 550 million years before splitting into Laurentia, Siberia and Baltica with the main landmass of Gondwana in the south.
Then the famous Pangea appeared 300 million years ago.
This great mass began to disintegrate about 200 million years ago, during the early Jurassic, eventually forming the modern continents and the Atlantic and Indian Oceans.
And the next supercontinent will be Amasia.
Lead author Dr. Chuan Huang said in one: pronunciation: ‘The resulting new supercontinent is already called Amasia because some believe that the Pacific Ocean will close (unlike the Atlantic and Indian Oceans) when America collides with Asia.
History shows that a new supercontinent is formed every 600 million years and the last one was Pangea which was formed 300 million years ago
“Australia is also expected to play a part in this important event on Earth, colliding first with Asia and then connecting America and Asia once the Pacific Ocean closes.”
The Pacific Ocean formed about 700 million years ago when Rodinia started to break up, making it the oldest ocean of the bunch.
However, it is also shrinking 0.19 square miles per year due to plate tectonics shifting beneath the seafloor.
Co-author John Curtin Distinguished Professor Zheng-Xiang Li, also of Curtin’s School of Earth and Planetary Sciences, said that if the entire world is dominated by a single continental mass, the Earth’s ecosystem and environment will change dramatically.
“Earth as we know it will be drastically different when Amasia is formed. Sea levels are expected to be lower and the vast interior of the supercontinent will be very arid with high diurnal temperature ranges,” Li said.
“Currently, the Earth is made up of seven continents with very different ecosystems and human cultures, so it would be fascinating to imagine what the world could look like in 200 to 300 million years.”
