Solid internal rotation Nucleus to her a land It’s estimated to have stalled recently and appears to be preparing to reverse its move in the opposite direction, according to Chinese scholars.
Based on the indications so far, it is likely that the reverse spin will be completed within the next decade, while possible impacts on the planet’s surface will be investigated.
researchers led Earthquake world Xiaodong Song of Peking University, who published the related publication in the journal Nature Geoscience, based their estimates on seismic wave analysis of nearly identical earthquakes, which have penetrated the Earth’s core following similar “paths” for the decade 1960 to present.
The analysis concluded that after the 1970s the inner core was rotating faster in an easterly direction, even between 2009-2011 its rotation appeared to I stopped, possibly due to the imminent reversal of the direction of rotation. The researchers believe that the impending new shift in the core’s rotation in the opposite direction, this time to the west, is part of a possible periodic cycle It lasts six to seven decades (Theory needs confirmation).
Based on this model, the core is expected to rotate westward with increasing speed until 2040, when it will stop and reverse its eastward motion again.
inner core – with an estimated radius of 1220 km and Consists of It’s mostly iron and nickel, with temperatures similar to the Sun – it’s separated from the rest of the solid Earth by its liquid outer core, which allows it to rotate differently than the planet itself.
The internal circulation of the heart is affected by magnetic field Created by the molten outer core and balanced by the gravitational effects of the mantle, Earth’s intermediate layer between the core and crust.
How fast the nucleus rotates and how much it changes remains a matter of scientific debate.
How the spin direction of the inner core is related is also discussed geophysical changes On the surface of our planet, such as the magnetic field and the length of the day, where interaction is assumed.
