The theory of platonic tectonics has already been formulated at the beginning of the 20th century Alfred Lothar Wegener. Although they were accepted by some experts only at that time, subsequent scientific discoveries of his later geological discoveries were convinced. The theory says that parts of the earth's crust, lithospheric plates, are constantly moving, interacting with one another and transforming the surface of the Earth. We know what our planet looked like. But what will it look like in the future?
The current distribution of the continents results from the collapse of the pracontinent called Pangea. It was formed more than 300 million years ago and its degradation began gradually about 180 million years ago. According to scientists, our planet is about halfway through the cycle, which has resulted in the creation of another supercontinent. What does it look like? Four scenarios are possible.
Novopangea
At the present time, while the Atlantic Ocean is expanding steadily, the Pacific is gradually narrowing. If we assume that this trend will continue over the next few decades, the world will turn into a supercontinent called Novopange. South America would then associate with Antarctica, which was moving north-west, then with Eurasia, which was already connected to Africa heading north.
Pangea Ultima
However, the current trend may change in the long run. It is possible that the gradual expansion of the Atlantic will slow down or eventually stop altogether. The vision of the supercontinent Pangea Ultima lies in the interconnection of all the major parts of the world that surround the vast Pacific Ocean.
auric
However, if new subduction zones were created in the Atlantic, the Pacific Ocean would be "not only" Atlantic but also that of the Atlantic. The supercontinent Aurica would result from the division of Eurasia, the progressive link of its eastern part with North and South America, Australia and Antarctica. Something later, Europe and Africa would join the supercontinent.
Amasia
At the present time, we can see that the tectonic plates in the southern hemisphere are moving progressively towards the north. In the future, Amasia could also emerge. This supercontinent would mean that most of the continent is moving gradually towards the North Pole of the Earth. Africa, Australia and South America are gradually pushing Eurasia and North America towards the poles, all of which are interconnected. In this case, it would remain only Antarctica.
