Changes in the shape of the internal core of Land For the last 20 years, scientists have recorded in their research, which may affect the function of our planet’s magnetic field, which is vital to surface living as it protects all kinds of radiation from its radiation. Sun.

According to the latest data, the Earth’s internal core is allegedly distorted by 100 meters or more at its height.

THE inner core rotates independently of the liquid outer core and the rest of the planet. Without this move, the Earth would die and look more like the barren Mars, who lost his magnetic field billions of years ago.

Research is published in the scientific journal Nature Geoscience. Scientists initially tried to find out why the rhythm of the inner core may slow down in relation to the rotation of the Earth before it accelerated in 2010. Understanding the way the Earth’s core operating is essential for understanding it magnetic field that protects the planet and if this could be weakened or even stopped in the long run.

A mysterious part

The interior of our planet is an extremely mysterious place. The core is about 4,000 miles from the surface of the Earth. So, in order to try to unlock its secrets, some researchers measure the earthquake waves caused by earthquakes. The way the waves travel, reveals the type of material they passed, including the inner core, and helps to form a better image of the interior of the planet.

The new analysis examined earthquake -wave patterns from earthquakes that were repeated in the same location between 1991 and 2023. This helped to show how the internal core changes over time.

Professor Vidale He found more evidence to support the theory that during these years, the pace of the inner core slowed around 2010.

The phenomenon was observed at the boundary of the inner and outer core, where the inner core is close to melting point. The external core fluid flow, as well as the attraction of an uneven gravity field, can cause deformation.

How does the phenomenon evolve

Over time, the wet outer core freezes in the solid inner core, but to do so, it takes billions of years until it becomes completely solid.

This would definitely mean the end of life on Earth, but by then, it is more likely that our planet has swallowed the sun.

“Most likely, this finding does not even affect our daily lives, but we really want to understand what is happening in the middle of the earth,” said one of the scientists involved in research.

It is possible that changes are linked to changes in the magnetic field of Earth. “The magnetic field has been jerking at various times in recent decades and we would like to know if this is related to what we see on the internal boundary of the core,” said Professor Vidale.

“We are not 100% sure we are interpreting these changes properly,” he said, adding that the limits of scientific knowledge are changing.
