A change in the rotation of the Earth’s inner core

Scientists are trying to learn about Earth’s inner core from astronauts. In this regard, experts from the Australian University (ANU) have discovered evidence of another layer of the inner layer of our planet. According to the researchers, the new layer is 400 miles across, a ball of metals like iron and nickel, which holds a record of Earth’s ancient history. Before this discovery, scientists had discovered 4 layers of the earth and now one more has been added. Scientists have discovered this secret layer by analyzing seismic waves.

According to the research, the earthquake waves travel at such an angle in the center of the earth, which gives an indication of another layer inside the inner layer. Experts say that this discovery will provide new means of investigation regarding the inner layer of the earth. The door will open.

This new layer indicates a significant event in the Earth’s past, which had a significant impact on the core of our planet and thus explains the formation of the Earth’s magnetic field. The magnetic field plays an important role in protecting the Earth from the sun’s harmful rays and preventing water from escaping into space. With the help of their new research, scientists at the University of Tokyo in Japan have shown the idea that an unknown substance found in the inner layer of the Earth may be silicon.

Scientists have long been trying to figure out what other elements besides iron and nickel (a silver-like metal) are present in the Earth’s inner layer. But now, by artificially creating the extremely hot temperature and pressure found in the inner layer of the earth, scientists have come to the conclusion that this material is silicon. This discovery may help to understand the Earth and its creation process.

Eiji Oh Tani, a professor at the University of Tokyo and head of the research, says that silicon is the main material that makes up about five percent of the Earth’s inner layer, which is found in iron and nickel alloys. The innermost layer of the Earth. It is like a solid ball and has a radius of about 1200 km. Being so deep, scientists cannot study this layer directly, but they can certainly try to understand it with the help of seismic waves that pass through it.

In recent research, experts have found that the Earth’s solid interior is the same size as Pluto and is a hot ball of iron. According to scientists, it has stopped rotating like the rest of the planet and may even be rotating in the opposite direction. The planet exists. This solid inner core (inner core) of the Earth itself can rotate freely, as it is surrounded by only liquid metals.

About this solid inner core, whatever information is gained comes from measuring seismic waves. These waves can also be generated by nuclear explosions and they pass right through the center of the Earth. To learn about the movement of this inner core of the Earth, experts have analyzed repeated earthquakes and the resulting waves over the past six decades. Researchers Xiaodong Song and Xie Ying from Beijing, China. from university. They say that in 2009, the movement of the Earth’s inner core stopped and then it turned in the opposite direction.

The center of the earth rotates like a swing. A complete rotation of the center takes about seven decades, which means that it changes direction about every 35 years. The solid core first reversed direction in the early 1970s, and its next cycle is slated to begin in the mid-2040s. According to researchers, this rotation is linked to the length of the day on Earth.

This change is caused by small variations in the time it takes for the Earth to spin on its axis, but more research is needed. Current research cannot pinpoint what the Earth’s inner core does and how it affects those living on Earth’s surface. Experts say that all the layers of the earth from the inner layers to the outer surface are closely connected.

The surface of the earth, which is called the “constellation” is actually a very thin membrane. This surface is about seventy kilometers deep. The Earth’s ‘inner core’ is made of iron and nickel, while the outer core (the outer part of the core) is liquid iron and nickel. The distance between this outer center and the outer surface of the earth is about 2900 km. The solid core of the Earth is about 2600 km in total, while the outer core is 22.500 km. Due to the presence of iron in the core of the earth and then the movement of the earth on its axis, the earth creates a magnetic field around itself.

It would not be wrong to say that the earth is also a rotating magnet. Because of this magnet, the radiation rays and particles from the sun cannot reach the surface of the earth, but the electromagnetic field of the earth destroys them outside, while such particles that reach the earth are also poles. turn to The Northern Lights in the North Pole and even in the northernmost regions of Europe are proof of this phenomenon.

If the Earth’s magnetic field did not exist, the Sun’s radiation would kill life on Earth, then the Earth’s atmosphere, an invisible balloon-like mass of gases above the Earth’s surface. Guarantees life on earth. This sphere burns the space rocks moving towards the earth by the force of friction in the air. If it is not an atmosphere, there will be no possibility of life on earth, but everything will be destroyed by it.
