According to a recent supercomputer simulation of Earth’s ever-drifting tectonic plates, the Pacific Ocean’s days are numbered and the world’s next supercontinent will soon merge Asia and the two Americas. According to Australian experts, the Pacific Ocean may be shrinking by as much as one inch every year.
The Earth’s landmasses will eventually converge, albeit it won’t happen for 200 or 300 million years. The Americas and Asia will smash together to form Amasia, a new supercontinent. Oceanic rock and continents make up the lithosphere, which is another name for the crust of the Earth. The mantle, a substantial layer of molten rock covering thousands of kilometres, rests on top of the lithosphere.Earth’s continents move over the mantle at a moderate pace. At a speed of around seven millimetres per year, one of the plates that is moving more quickly is migrating northward.
Although there is disagreement among experts over the shape and formation of the upcoming supercontinent, it is clear that the Pacific Ocean will eventually disappear.One of the first researchers, American geologist Christopher Scotese, proposed the name Pangea Proxima for a hypothetical supercontinent that would resemble Pangea as a single landmass 200 million years ago.
According to a 2012 Science article, the geological record “reveals that there have been three supercontinents in the past 2 billion years or so.”
