Earth’s Core: Scientists are doing many types of research to know about the activities related to the Earth. Recent research has found that its layer is changing.

Earth Iron Core Study: Our earth is full of mysteries and there are many such things, about which scientists are still searching to know. Now one such news has come out, which is no less than a mystery. Scientists have come to know that the Earth’s crust is changing. But the reason behind this is not known. Seismologists at the University of California, Berkeley have found that Earth’s iron core is expanding more than one side. This happened in the Banda Sea of Indonesia.
It is being said that this change is happening due to the formation of iron crystals. But on one hand it is being seen more. Whereas on the other side ie the bottom of Brazil is decreasing (Earth Iron Core Lopsided). Due to some unknown reasons, heat is coming out of the outer layer of the earth at a high speed in Indonesia. Whereas on the side of Brazil it is less visible. Researchers believe that this may be due to the Earth’s magnetic field. Earth’s core is made of iron, outside of which is the liquid outer core. After this there is the rocky mantle again.
weakening magnetic field
At the same time, during the formation of crystals, the heat that is released from the iron and comes out of the rock, the cold material comes down from it. This creates a magnetic field. Earlier it was revealed that the Earth’s magnetic field is weakening between South America and the South Atlantic Ocean. This area is called SAA i.e. South Atlantic Anomaly. There is also a matter of concern that this area is spreading. which is moving towards the west. It is estimated that in the coming five years, it will increase by 10 percent as compared to the year 2019.
decrease in magnetic field
The Earth is believed to be more than 4 billion years old. While its inner layer is half a billion to 1.5 billion years old. There have been many such activities in this, which remain a mystery to scientists even today (Study on Earth). He is doing research to solve them. In recent research, it was also found that the intensity of the magnetic field has decreased by about 9 percent in the last 200 years. This decrease is seen more between Africa and South American region. Scientists say that there is a gradual change in the poles, it is not seen suddenly.
