A new study by seismologists from the University of California and recently published in Nature Geoscience reveals that the region of the core located in the area under the Indonesian Sea is larger than the part at the other end, just below Brazil.

For reasons that are still unknown, the solid iron inner core of the planet is growing “faster on one side than the other” and has since “began to solidify from molten iron more than 500 million years ago.” , as they explained in a statement. Issued by the University of California, Berkeley.

Effects on the Earth’s magnetic field

In this sense, more growth on the eastern (left) side than on the west indicates that “something in the Earth’s core or the Earth’s outer mantle below Indonesia is removing heat from the inner core at a faster rate than the other side, below Brazil”. Thus, faster cooling on one side than the other would speed up the crystallization of iron and the growth of the inner core.

As a result, this will have implications for the planet’s magnetic field and history, because “convection in the outer core driven by the release of heat from the inner core is what today drives the magnetic field-generating dynamo that protects us” from dangerous particles from the sun.
