The inner core of the Earth gradually slows down its rotation
and moves slower than the earth's surface,
Azernews reports.
This is the conclusion reached by American and Chinese
scientists at the University of Southern California.
"The movement of the Earth's inner core has been discussed by
the scientific community for two decades, with some studies even
showing that the inner core rotates faster than the earth's
surface. However, new data from the University of Southern
California irrefutably indicate that around 2010, the rotation
speed of the inner core slowed down and began to lag behind the
speed of the Earth's surface," says a publication on the
university's website.
"I was greatly puzzled by the first seismograms hinting at this.
But then a couple dozen more observations indicating the same thing
left no doubt: the inner core slowed down for the first time in
many decades. Recently, scientists have been arguing about this
this way and that, but our latest study puts an end to this
dispute," said John Vidal, professor at the Faculty of Earth
Sciences.
According to Professor Vidal, the slowdown in the rotation of
the Earth's core is caused by some stirring of the surrounding
liquid mantle, which creates the Earth's magnetic field, as well as
the gravitational influence of the upper layers of the solid
mantle.
What the consequences of this slowdown may be, scientists have
not yet decided to judge. According to Professor Vidal, this can
change the length of the day by an almost imperceptible amount, on
the order of a thousandth of a second. Nevertheless, scientists
intend to carefully monitor the process.
