Chinese scientists have suggested that the Earth's core began to rotate in the opposite direction
Scientists from Peking University analyzed the trajectories of seismic waves caused by earthquakes and found out that the rotation of the solid inner core of the Earth slowed down in the period from 2009 to 2020, and now, perhaps, it began to rotate in the other direction altogether, according to a study published in Nature Geoscience.
Scientists point out that the research results correspond to observations of changes in the Earth's magnetic field and the length of the day. The rotation of the inner core of the planet is caused by the magnetic field created by the outer core. This proves the dynamic relationship between the layers of the Earth.
Most of the inner core consists of nickel and iron, so it is solid, and it is separated from the outer layers of the Earth by a liquid core, which allows it to rotate differently from the whole planet.
