Scientists have raised concerns that the Earth's inner core may completely halt its rotation by 2040, according to a recent paper published in Nature. The study suggests changes are occurring deep ...

These changes, observed for the first time, could explain some variations in the rotation of the inner core and even influence the length of days on Earth. The inner core, located about 3,100 miles (5 ...

Scientists observed shape alterations at the inner core's outer boundary, potentially due to outer core turbulence. This discovery fuels ongoing debates about differential rotation rates and inner ...

Previous research has found that the rotation of the inner core is slowing down relative to the rotation of the external crust, which may cause minute changes in Earth’s rotation and subtly ...

A new study has found evidence that the Earth's inner core may have changed shape ... Subsequent studies showed further evidence that the rotation of the core has been slowing down compared ...

Since the 1990s, models and seismic measurements have indicated that Earth’s iron-nickel inner core moves at its own pace. Over decades, the rotation of the inner core speeds up and slows down ...

The deeper radiative zone reaches down to the core; within the radiative zone, the solar plasma rotates as if it were a solid body. Within the tachocline, the differential rotation of the ...

The inner core is out of reach for direct observation or sampling. Scientists have relied on examining the seismic waves from large earthquakes and their interaction with the core to gain insights.

Differences in these waves, observed at different times, allow scientists to measure changes in the core's position and calculate its spin. "Differential rotation of the inner core was proposed as a ...

“Differential rotation of the inner core was proposed as a phenomenon in the 1970s and ’80s, but it wasn’t until the ‘90s that seismological evidence was published,” said Dr. Lauren ...
