Forces deep underground seem to be deforming Earth's inner core
New ScientistFEB 11
The discovery of inner core deformation represents a groundbreaking advancement in understanding Earth's internal dynamics. The changes suggest a more dynamic and interconnected relationship between the inner and outer core than previously thought, potentially affecting the planet's magnetic field generation and rotation patterns.
The observed changes might have alternative explanations beyond shape deformation, such as unrelated changes in the outer core or convection within the inner core itself. The limited data coverage and indirect nature of seismic measurements make it challenging to definitively determine the exact nature of these changes.
