This is the first time another layer has been found inside the Earth (core), which is not a liquid current of any metal; Not even a solid. Something in the middle of it, which was unknown to us for so long, said a report in the Anandabazar newspaper.
According to the report, the role of that level and its creation is still shrouded in mystery. However, scientists believe that this layer, hidden in the heart of the Earth, may have played a role in the collision between the tectonic plates that caused the earthquake. In that case, the discovery could play a significant role in predicting earthquakes in the coming days.
The research paper is published in the international scientific journal Journal of Geophysical Research: Solid Earth. The researchers said, “This time, the secret inside the world will be known. However, the meaning of that word has not been understood yet. ‘
It has been known for so long that there are two layers inside the Earth. One starts 1,600 miles or 2,797 kilometers below the surface. This is the inner layer of the Earth or the outer layer of the core. At this level, the liquid current of the metal flows. The temperature here is 4 to 9 thousand degrees Fahrenheit or 2 thousand 204 degrees to 4 thousand 972 degrees Celsius. Approximately close to the temperature of the Sun’s back (6,000 degrees Celsius).
It was also known that the inner layer of the Earth’s core starts at 3,200 miles or 5,150 kilometers below the surface, where iron is in an authoritarian state, and also some nickel.
However, scientists have been skeptical since the 1980s that there could be more between these two levels. But it has not been possible to search for so long that the temperature of the upper layer of the Earth’s core is close to the Sun’s back temperature.
Joe Stephenson, a researcher at the Australian National University in Canberra, and his colleagues, took a slightly different approach to understand what the Earth’s core image looks like. They used earthquake waves to take that picture.
In Stephenson’s words, “We understand that the place is not filled with pure solid metal. There is metal or something else in some other condition. However, his character was not understood.
Researchers, however, say that if the mystery is unraveled, the root cause of the collision of tectonic plates may be known in the coming days. Maybe it will be helpful to predict earthquakes.
