Over billions of years, Earth has experienced dramatic geological ups and downs. Earth’s history is marked by the formation and breakup of continents, Changes in the circulation patterns of ocean currents and the emergence of life. These changes have raised an intriguing question: Will Earth become a supercontinent again?
many continents have been formed
Scientists believe that the Earth passed through three supercontinents Separate. The most recent was Pangea, which formed about 300 million years ago and broke up about 200 million years ago. Since then, the continents have been slowly moving towards their present positions. Although scientists are certain that Earth will once again form a supercontinent, there is some uncertainty about when this event will occur. Some studies estimate that it will take 100 to 200 million years for Earth to become a supercontinent again. This means that in theory, the process can start at any time.
However, other studies suggest that it may take longer. These studies are based on the fact that Earth is experiencing a decrease in the movement of the continents, This reduction means that the speed at which the continents are moving is less than 200 million years ago, meaning that the formation of a supercontinent may take a billion years.
What might the next supercontinent look like and how big?
In addition to the uncertainty about timing, There is also uncertainty about what the next supercontinent will look like. This is because the continents are moving at different speeds and in different directions. For example, the African continent is moving north at a rate of about three centimeters per year, while the North American continent is moving east at a rate of about two inches per year. All this could mean that the configuration of the supercontinent would be very different from the configuration of Pangea.
Once a supercontinent has formed, it may break apart again, giving rise to a new configuration of the continents. This has happened before and is likely to happen again in the future.
opinion against thesis
Even then, Some reasons why the Earth did not become a supercontinent, For example, global warming is affecting Earth’s climate, which can affect the movement of tectonic plates. In addition, there are other factors such as volcanic activity and eruptions that can affect the movement of tectonic plates.
