The Earth looks for 200 million years



The outer layer of the earth, stuck on a solid crust, consists of broken pieces, like shells of powdered egg.

These pieces, the tectonic plates, move around the planet a few centimeters.

Sometimes they unite together and combine with a supercontinent one hundred million years before the break. Conversation notify

Plates are then dispersed or dispersed and moved away from each other, until they finally meet again for 400 to 600 million years.

The last supercontinent, Pangea, was born about 310 million years ago and started breaking 180 million years ago.

The next supercontinent can be termed 200-250 million years, during the phase that is scattered throughout the current supercontinent cycle. The question is: how will the next supercontinent, and why?

The next supercontinent is based on four basic scenarios: Novopangea, Pangea Ultima, Aurica and Amasia. Each form depends on different scenarios, but ultimately separates Pangea and how continents are still moving in the world.

Pangea's fractures led to the formation of the Atlantic Ocean, which is still wider and broader today. As a result, the Pacific Ocean is shut and narrower.

The Pacific is a ring of subatomic rings on the edges ("fire ring"), where the ocean floor goes down or enters the continental plates and enters the Earth's interior.

In it, the ocean oceans are recycled and volcanoes can be added.

The Atlantic, on the other hand, has a large oceanic ridge that creates a new ocean plate, but has two subduction zones: the Caribbean Antillean Arch, and the South American and Antarctic Arc Scotland.

1. NOVOPHANGEA

If we continue in current conditions, the Atlantic continues to open and the Pacific closes, it is the next supercontinent in the Pangea antipodes.

The Americans would go to the north of Antarctica and be hit by African Eurasian.

The following supercontinent was named Novopangea or Novopangaea.

2. PANGEA LAST

The Atlantic opening will, however, slower and actually shut in the future.

Two small subductive subduction subsoilers can expand the East Coast of America to reform Pangea. In America, in Europe and in Africa, they have returned to supercontinency Pangea Ultima.

The supercontinent would be surrounded by a super-ocean superpower.

3. AURICA

However, if new Atlantic subduction sites need to be developed – something that is already happening – both in the Atlantic Ocean and in the sea could be stuck in the sea.

This means that it should replace a new sea basin.

In this scenario, it is now crossing Asia and Asia, Asia, Asia, Asia, Asia, Asia, Asia, Asia, Asia, Asia, and Asia. The result of the formation of the superposition of Aurica.

It would travel to the north of the Australian continent in the midst of the new continent, east Asia and America, near the two sides of the Pacific.

European and African dishes would go to America as an Atlantic closure.

4. AMASIA

The fourth stage announces a completely different fate of the future of the Earth. Some tectonic plates are currently moving north, including Africa and Australia.

Due to the anomalies left by Pangea, due to the depths of the Earth's interior, some sort of deriva is called a mantle.

Due to the northern drift, the continents, except Antarctica, continue north to north.

This means that they would meet along the North Pole of the supercontinent called Amala. In this scenario, most of the Atlantic and Pacific would be open.

Among these four scenarios is probably Novopangea. The current continental plate is a logical progression, in other words, and the other three take on another process.

New areas of Atlantic subdivision should be Aurica, the reversal of the opening of the Pangea Ultima Atlantic, or the anomalies of the Earth within the Pangea Amasia.

The study of the tectonic future of the Earth helps us to think about the limitations of our knowledge and think about the processes that extend our planet to a long time.

The terrestrial system generally thinks about it, and it raises other questions: what will the next supercontinent climate do? How will the ocean circulation work? How will live to live and adapt?

The kind of questions that push the limits of science are those that impel the limits of our imagination.
