Jakarta, CNBC Indonesia – Not long ago, there was a surprising report from US scientists. This report by US scientists states that the core of the earth under the Indonesian sea grows sideways.
Scientists report that the dense iron core at the center of the planet has grown faster under the Banda Sea in Indonesia.
This is said to occur because the core of the earth in Indonesia loses heat faster than other regions such as Brazil. As a result, cooling occurs faster due to the crystallization of the core constituent iron.
This was revealed by seismologists from the University of California, Berkeley, United States, as quoted from The Independent, recently.
The discovery came to light while scientists were studying seismic waves, the underground vibrations produced by earthquakes. The waves pass through the planet’s dense iron core.
Keep in mind, the earth’s core is about 3,000 kilometers below the earth’s surface. This part is shaped like a ball and contains iron and nickel.
Above the Earth’s core is the mantle, which consists of the inner mantle (300-2,890 km below the earth’s surface) and the outer mantle (10-300 km below the earth’s surface). The outermost layer is the earth’s crust.
Surprisingly again, this has happened since 500 years ago. However, it is not yet known why the cooling process occurs rapidly in Indonesia.
“The only way we can explain it is that one side is growing faster than the other,” said study lead author Daniel Frost, a seismologist at the University of California, Berkeley.
The discovery that the Earth’s core in Indonesia loses heat more quickly led scientists to new conclusions, about why iron crystallization is more inclined to the west (Banda Sea) than in the East (Brazil).
Researchers say there is asymmetrical growth, 60% higher to the west side. But researchers believe this asymmetrical growth does not mean there will be other records or risks that make it unbalanced.
Even so, Frost says there are other mysteries that remain to be solved.
“The question is, does this change the strength of the magnetic field?” she says.
The earth’s magnetic field is a geomagnetic field that extends from the interior of the earth to the boundary where it encounters solar radiation. Simply put, Earth’s magnetic field reflects most of the solar wind, which is a stream of charged particles from the sun that are capable of ionizing (decomposing) in Earth’s atmosphere.
The compass that humans use depends on the earth’s magnetic field. Animals also use the earth’s magnetic field to migrate.
Frost said he would soon conduct research again to discuss this. Frost says he has begun work on new research with a geomagnetic team to investigate some of the mysteries of core tilting growth.
