Swirls of liquid iron may be trapped inside Earth’s ‘solid’ core

Recent research challenges the conventional understanding of Earth’s solid inner core, revealing that it may not be entirely solid throughout. Instead, it appears to be a complex mixture of solid and liquid components extending all the way to the center.

The study draws upon the analysis of faint seismic echoes generated by earthquake waves that bounce back to the Earth’s surface from the depths of the planet, Yahoo News reported.

These findings indicate that the inner core exhibits greater diversity than previously believed. As the liquid outer core solidifies, the inner core gradually expands by about a millimeter (0.04 inch) each year.
