Scientists believe the core of the Earth may be melting, a process linked to activity on the surface.
"The standard view has been that the inner core is freezing all over and growing out progressively, but it appears that there are regions where the core is actually melting," says researcher Sebastian Rost.
"The Earth's inner core is a ball of solid iron about 1,500 miles wide, about the same size as the moon."
