One of geology’s basic principles is that the Earth is made up of four layers: the crust, the mantle, the outer core, and the inner core. But this may be squashed in light of a new study that ...

Earth is made up of several layers: the lithosphere, asthenosphere, lower mantle (also known as mesospheric mantle), outer core and inner core.

The inner core grows (and rotates) in response to the coupling with other layers, which are both gravitational and electromagnetic," Pham said. Earth isn't the only place that experiences quakes.

The liquid outer layer of the core is responsible for producing Earth’s magnetic field, which is further stabilized by the solid inner section. [Related: The Earth’s inner core could be ...

As Song explained, the Earth's inner core has a "dynamic" relationship with two of Earth's major layers. First, there is an electromagnetic coupling with Earth's outer core.

A pair of seismologists documented new evidence of a fifth layer: a 400-mile-thick solid metallic ball at the center of Earth’s inner core — like the smallest figurine of a massive, planetary ...

Understanding how the inner core rotates could shed light on how all of the Earth’s layers interact. In this study , seismologists Yi Yang and Xiaodong Song looked at seismic waves.

Researchers are still discovering more about the Earth's center.A team at Australian National University (ANU) has found evidence of a new layer to the planet sitting within the inner core. This ...

They found that the inner core was rotating in the same easterly direction as the Earth itself, albeit slightly faster than the other solid layers—the mantle and surface.

Scientists first had a hunch that the inner core was moving in the 1990s, he said. It has taken years to back up that theory with hard evidence, mainly because of the difficulty of studying a mass ...

It is true that the outer core generates electrical currents that sustain the planet’s magnetic field, but Vidale says shifts in the Texas-size inner core are too minuscule to have an impact.
