You may have heard or seen something about earthquakes, tsunamis, volcanoes, and other types of natural disasters. You might not, however, be aware of the inner core of the earth’s crust ceasing to rotate.
Since we are all on the surface of this enormous ball known as the earth, it is quite obvious. As a result, we are more interested in what is nearby than what is 5,000 kilometres away. Few people actually give a damn about what goes on below us. In the meantime, what is below us can have a significant impact on what is above it.
THE EARTH’S INTERNAL CORE HAS STOPPED ROTATION
Online news stories are claiming that the Earth’s perpetually rotating inner core has stopped turning. However, there is no need to panic because, according to researchers, it only happens once every seven decades.
At Peking University in Beijing, geophysicists Yi Yang and Xiadong Song recently published a new study in the journal Nature Geoscience. The study describes the inner core of the earth’s movement in detail. The inner core is mostly made of iron and molten liquids.
They discovered that the inner rotation of the Earth’s core slowed before pausing altogether. This pause appears to be connected to the core’s slow rotational retreat. According to research, this shift takes place every seven decades. The last time something like this occurred was in the 1970s.
We don’t have a long history of understanding the inner core, according to Song’s spinning theory from 1996. In the past, some people held the hollow core theory. However, the current generation thinks that the earth’s core is made of molten iron. Additionally, we think that the Earth’s core rotates at a different rate than the surface.
The new study claims that seismic waves were followed through the core to observe how it acted on the other side of the earth. According to the study, this globally consistent pattern “indicates that inner-core rotation has recently paused.
The Earth’s mantle and the spinning of its core are thought to interact, according to the authors. The core is not spinning for no reason, as a result.
WHAT HAPPENS WHEN THE DIRECTION OF THE EARTH’S INNER CORE CHANGES?
According to the study, many geophysical observations are congruent with the decate of periodic occurrences. The length of the day and the Earth’s magnetic field may be included in this.
