By analyzing decades of seismic data, researchers from the University of Southern California have discovered that the surface of the inner core appears to deform under the influence of the outer core.

The inner core spins independently from the liquid outer core and from the rest of the planet. Without this motion, Earth would die and become more like barren Mars which lost its magnetic field ...

The Earth's internal layers including the mantle, outer core and inner core. New research shows the inner core undergoes structural transformation likely caused by outer core disturbance.
