Why does the lava of iron in the depths of the earth reverse the flow?

<> because the earth rotates counterclockwise along the earth's axis, the lava of iron will of course flow counterclockwise.

According to foreign reports, scientists have always believed that it will take 4,000-5,000 years for the reversal of the Earth's north and south magnetic poles, and according to the study of the previously established core model, the poles will not flip faster than this. However, the latest evidence shows that it only takes a few years to complete the magnetic pole reversal.

In 1995, scientists discovered a well-preserved lava flow on Mount Stings, Oregon, USA. An expedition led by Scott Bogue of Occidental College in Los Angeles studied the rocks and found that these ancient magma had unusual magnetic fields. It was found that the magnetic field in this area changed at a rate of 6 degrees per day, which is 10,000 times faster than normal.

The magnetism was preserved by the magnetic crystals formed by the cooling of the lava flow. However, there is a lot of controversy about this discovery, and many scientists have questioned the theory of rapid reversal of the magnetic field.

But today, Borg and Jonathan Glen of the U.S. Geological Survey have found a sample that proves the Earth's poles are flipping in Mount Battle, Nevada, about 15 million years ago. This lava flow sample from Nevada shows that the magnetic field in the area changed by 53 degrees in one year. The lava had cooled down at first, but was reheated within a year as it was buried under new lava.

The crystals in the rock are remagnetized by the new lava, creating a 53-degree change in the magnetic field. At this rate, it would take less than 4 years for the poles to flip. Borg also said it could also be a period of abrupt acceleration during the magnetic stabilization.

According to some geologists, the polar reversal has been delayed for a long time because the Earth's magnetic field has been weakening over the last century. And the last time the poles were reversed was born 780,000 years ago. Even if the Earth's poles were to reverse rapidly, many people would not notice.

Although many scientists believe that the polar reversal is related to the convection of liquid iron in the Earth's outer core, no one knows exactly why the polar reversal occurred.

Because the Earth rotates counterclockwise, and it's the very center.

The temperature of the earth's core is greater than the melting point of the rock.
