The speed of rotation of the last and most important layer of the three layers that make up the Earth is decreasing rapidly. Scientists have recently sensed this movement in the inner core of the Earth and presented a detailed report whose results are very surprising. This movement was happening inside the Earth for about 14 years which has been detected now. This is the first time in 40 years that it is moving at a slower speed than the Earth’s surface. Do you know what will happen in the future if this speed of rotation keeps mismatching like this?
Let us tell you that the earth has three layers. The first and the uppermost layer is called the crust on which the world is settled. After this, the layer below is metal. The third and the innermost layer is the core. The changes that are being seen are being seen in this core. This is an extremely hot, very dense sphere of iron and nickel which is found at a distance of more than 4,800 km below our feet.
The universe moves at its own pace in a disciplined manner. The earth is also an important part of this universe on which we live. It also ‘moves’ according to its rules. But now recent studies show that the rotation of the inner core of the earth has been slowing down since 2010. That is, it has started decreasing. New research provides evidence that the inner core has started moving at a slower speed than the surface of the earth. Scientists from the University of Southern California (USC) have confirmed this. According to the report published in Science Alert magazine, this can have a significant impact on both the stability of the earth’s magnetic field and the duration of our days. However, this change in days can be of 1 second or a few seconds in the initial time. More information is yet to come on what its long-lasting effect can be.
The result of this will be that the length of days will change. Some scientists say that this will make the days shorter than today, while some say that this length will increase. Mr. Vidale, Dean Professor of Earth Sciences at USC Dornsife College of Letters, Arts and Sciences, says that due to this change in the entire planet, our days may increase. While according to the report published in the Indian Express, for a long time the scientific community has been citing studies on the slow speed of the inner core, which say that this core rotates faster than the surface of the Earth.
