On the basis of this principle, scientists at Curtin University (Australia) claim that the Pacific Ocean will expand and expand. will become the only ocean on Earth and the continents will form a new supercontinent.
Supercontinents were formed and separated by two processes called "introversion" and "extroversion", according to the study of researchers published in the journal Precambrian Research [19659004] During the first process, the continent was divided into land mbades separated by an inner ocean, where sucking phenomena were developing which led to the dive of the oceanic coast in the warm mantle of the Earth and, consequently, of the oceanic waters towards the interior of the lands. planet Thus, the continents "joined" and formed a new supercontinent surrounded by the same superocean.
With regard to the process of extroversion, the inner ocean became a new super-ocean around the new supercontinent, occupying the depression that had formed in the old coastal lines that collided.
According to the version proposed by the Australian experts, the supercontinent Pangea, which grouped most of the land mbades 335 million years ago, was formed when the supercontinent Rodinia, which existed there 1,100 million years ago, collapsed under the influence of forces
In turn, Rodinia was formed through a process of introversion after the fragmentation of the previous supercontinent Nuna , also known as Columbia, which existed between 1800 and 1300. The meeting and separation of the old supercontinent occurred by alternating cycles lasting about 600 million years, said the scientist. main study, Zheng-Xiang Li, quoted by the official website of Curtin University.
According to what Li understands, if this alternative scheme is respected, the next supercontinent will be formed by the proc of introversion. The internal oceans created by the separation of Pangeia – Atlantic, Indian and Antarctic – will join and the Pacific will expand to become the only super-ocean around the new supercontinent.
Still according to the scientist, these two alternate processes determine not only whether the super-ocean will survive, but also whether the Pacific fire belt will continue to exist.
"If the belt of fire survives with the super-ocean, the structure of the Earth's mantle will keep a pattern similar to that of the previous supercontinent, otherwise the mantle will reorganize completely," says the scientist.
