Unveiling the Textured Mystery of Earth's Inner Core

New research suggests that Earth's solid inner core may not be completely solid, but rather a mixture of solid and liquid. The inner core, composed mostly of iron and nickel, may have grown faster in the past and could contain swirls of liquid iron trapped inside. The study, based on seismic data, reveals that the inner core is more varied in texture than previously thought. The findings shed light on the process of solidification in the outer core and raise questions about the evolution of Earth's magnetic field over time.
