Peking University seismologists Yi Yang and Xiaodong Song, in a scientific paper published in the journal Nature Geoscience, indicated that the earth’s core began to rotate more slowly than the Earth itself. During the study, information about earthquakes was analyzed. Seismologists have been studying this phenomenon since 1995.
Previously, the core rotated faster than the Earth itself, but in recent decades (perhaps in 2009) it has begun to follow the natural motion of the planet.
A change in the rate of rotation of the Earth’s core can have consequences such as changing the length of a full day by a few fractions of a second. Now the Earth makes a complete revolution (in the inertial frame of reference) for sidereal days, their duration is 23 hours 56 minutes 4 seconds and 0.9 tenths of a second.
Other possible transformations include changes in sea levels and Earth’s temperature. This is reported by Brasil247 , a partner of the TV BRICS network.
