The findings have implications for our understanding of how the core influences the other layers of the Earth.
The rotation of the Earth's inner core may be reversing, scientists have found in a study that sheds new light on geological processes occurring deep within our planet., indicate that changes in the rotation of the inner core could take place on a scale of decades. The study's authors toldthe findings have implications for our understanding of how the core influences the other layers of the Earth..
Since this discovery, however, there have been several unresolved matters regarding our understanding of the inner core rotation when it comes to factors such as the speed of rotation and whether or not it varies.paper—Yi Yang, who is also affiliated with the SinoProbe Lab—to gather more data over a longer duration to test different models, resulting in the latest publication.
Their findings indicate that the inner core was rotating faster than the Earth's mantle and surface—in an eastward direction relative to the surface—from the early 1970s to around 2009. The rotation then appeared to pause from 2009 to 2011 or so. Since this period, the rotation seems to be gradually reversing, their data suggests.
"These results help us better understand how the inside of the Earth operates and how the different layers of the system interact as a whole," the authors said."Such multi-decadal oscillations also exist in the other Earth layers, such as the outer core, mantle and surface, indicating a possible resonating Earth system."
