Jakarta, CNBC Indonesia – Scientists found that the core of the earth under the Indonesian sea grows tilted. The dense iron core in the center of the planet is reported to have grown faster under the Banda Sea in Indonesia. This is what causes the planet’s heat to decrease below Indonesia.
This was revealed by seismologists from the University of California, Berkeley, United States.
The seismologists state that growth on one side of the molten metal is a product of iron crystals that form as molten iron cools, but something in the Earth’s outer core or mantle beneath the South Asian nation gives off heat at a faster rate than on the opposite side, below. Brazil.
That means, the Earth’s core beneath Indonesia loses heat faster than under Brazil.
Quoting Independent, the faster the cooling, the faster the crystallization of iron occurs and the faster its growth.
Such a difference has significant implications for the Earth’s magnetic field, and the convection currents in the core that generate the field. This is what protects us from harmful solar particles.
“We put a rather loose limit on the age of the inner core at between half a billion and 1.5 billion years – which could help in the debate about how magnetic fields were generated prior to the existence of a solid inner core,” said Barbara Romanowicz, UC Berkeley Professor of the Graduate School. in the Department of Earth and Planetary Sciences and Director Emeritus of the Berkeley Seismological Laboratory (BSL).
“We know the magnetic field existed three billion years ago, so other processes must have driven convection in the outer core at that time,” he added.
The asymmetrical growth in the Earth’s inner core does not mean there are defects or risks, thus making it unbalanced.
On average, the radius of the Earth’s inner core grows evenly about 1 millimeter each year. Gravity corrects the oblique growth in the east by pushing new crystals towards the west.
