Detecting giant lava tubes, can cause polarity to reverse the Earth's magnetic field

Polar Island will certainly cause no less harm for people, many people also consider it "the end of the world" of the Earth.

We all know that Earth's magnetic field is generated by a molten solid core of iron and nickel. At Earth's core its temperature can be as high as 5,700 degrees Celsius (hot approximates the Sun's surface).

At the end of the Ice Age, 41,000 years ago, there was a phenomenon of magnetic field reversal for several hundred years. Then, if you have a compass, its needle will be reversed in the direction!

This is a phenomenon that occurred several times throughout the history of Earth and now new research shows that this can recur but the main cause of it is similar to a giant lava lamp.

Inside this lamp is molten solid droplets that move up and down periodically.

According to scientists, the region above the Earth's north pole is like a giant lava lamp, which inside contains liquid solids that move up and down steadily and this will cause the Earth's magnetic field to be change, even reverse polarity.

Global Seismology (Global Seismology) Paula Koelemeijer working at Oxford University (UK) discovered this when receiving unusual seismic signals from earthquakes.

By studying signals from large earthquakes, in particular the shape and speed of seismic waves, the researchers discovered that the Earth's magnetic field is changing.

The polarization process will take place in a process, when the magnetic field at the two poles weakens and swapped each other, then the magnetic field will strengthen again at the end of this process.

Thus, in the process of polarity, the Earth is like a peeling snake, this will be when the Earth is "weakest" because there is no strong enough magnetic field, acting as the armor to prevent the solar storm enters the atmosphere.

The process of polarity takes place every few million years each time, but also tens of millions of years, its anomaly is something that our scientific level is still unpredictable.

But many experts predict that over the next 2000 years, the Earth will reverse again, then its impact on human activity, especially the communication system will be devastated and affected. to economics and many other areas.
