The seven continents are unstable and will merge into a supercontinent? Expert: It is possible that the continental plates are moving

Today’s earth is divided into “seven continents and four oceans”, and both the continents and the oceans are constantly changing. Many scientists believe that our earth may form an “eighth continent” in the future. ", the main area pointed out is the division of the African continent to form the "eighth continent" - East Africa. However, scientific research also points out that although our earth is dividing, it is also merging. The former supercontinent may How to say this again?

Of course, there is a saying that "the earth must be divided if it is united for a long time, and it must unite if it is divided for a long time." This seems to sound very reasonable, but isn't it? In fact, scientists' research is based on theory, and there is no definite statement that this will definitely happen to our earth.

The supercontinent we are talking about refers to "Pangaea". This is the map of the earth's appearance proposed by early geologists. After the supercontinent, the earth experienced continental drift or the movement of the earth's continental plates. The various continental plates that formed the earth today were originally divided into two continents: Laurasia in the north and Gondwana in the south. These two are the oldest continents, and then they moved again to form The "seven continents and four oceans" of our earth.

Of course, today's earth is not evenly distributed. The areas of the earth's "seven continents and four oceans" are not the same. This shows that the earth's plate activity is an uneven pattern. According to scientists, Research points out that our earth will evolve into a whole again, that is to say, the supercontinent will reappear on the earth, and the time will be 250 million years later. By then, the seven continents may have merged into a huge whole, and the supercontinent will be surrounded by Surrounded by oceans, scientists say this is how the supercontinent reappeared.

In long-term research, scientists have discovered that the movement of our earth's plates is cyclical, and now the changes in our ocean plates have been very obvious, and the seabed in the Pacific has also experienced downward movement. Shen, the Pacific Ocean is converging and the Atlantic Ocean is expanding. This is in line with most research by scientists. Indeed, more and more scientists are discovering changes in these two oceans, and the American continent is moving away from the European continent, the Australian continent, and the European continent. The Asian continental plate is also constantly moving.

Through analysis, it was found that the continental plates move about 15 millimeters per year, which means that the continental plates are moving. The seven continents are unstable and not static. Of course, for most people, this means moving. The distance is really "negligible", but the sum of a little makes a big thing is also a conventional explanation. If this continues, then the continents may eventually merge together, and such a supercontinent will appear again, and the only What has not changed much is the position of Africa and Antarctica. These two regions are equivalent to the merged position of the "center". This is the general situation.

South African geologist Chris Hartnady also simulated the reconfiguration phenomenon of continental plates and explained the state between all continental plates, so when the supercontinent re-Earths in the future, The pattern of the earth will change again, which is the current pattern of activity on the earth.

From the perspective of today’s earth pattern, although the continental plates move about 15 millimeters per year, from our personal perspective, the changes in the earth are not great, so the impact is not very big. However, if the earth’s continents are reorganized, This is very huge for all life forms living on the earth, including seasonal changes living in different regions, and their adaptability will change accordingly. At the same time, the process of reorganization of the earth's plates may also bring about other corresponding geological activities, such as volcanic eruptions, earthquakes and other problems.

So from this aspect alone, in fact, life on earth may face threats from nature, which are not good things. Perhaps the modern civilization established by humans today may suffer when the earth’s plates merge. The devastating impact, but judging from the continental plates moving at a rate of about 15 millimeters per year, that is hundreds or even tens of thousands of years later. This situation was only possible on the earth. At that time, the earth's civilization had undergone earth-shaking changes.

Don’t humans now say that they are emigrating to Mars? When immigration is actually implemented, there is no need to worry about the changes of the earth. Today's earth may be a "passenger" in the history of human civilization. In the future, we can go to farther celestial bodies to live, so it may be possible before humans immigrate to Mars. In the past, we could not see the reorganization of the earth's continents, because the plates moved very slowly. Unless there was a huge change in the earth and the reorganization of the earth's plates occurred quickly, such a crisis would be even greater.

Having said that, in fact, the earth's civilization is just a "passer-by". Life exists in life and death. According to scientific analysis, the earth also has a lifespan, and the longest lifespan is still a few billion years, because In a few billion years, the sun will become a red dwarf star. At that time, the earth will also be affected by the changes of the sun, which may destroy the existence of earth civilization. So whether the reorganization of the earth's continental plates happened before or after, let's continue to wait. .
