Scientists Discover Strange Aspects of Earth’s Inner Core

The Earth’s core, the deepest part of our planet, is characterized by extremely high pressure and temperature. It consists of a liquid outer core and a solid inner core.

The core is a 1,220-kilometer (760 mile) ball buried deep beneath the crust of Earth.

Highly diffusive light elements can affect seismic velocities, providing critical clues to understanding other mysteries in the inner core.

This means that the inner core of the Blue Planet has a strange composition of elements that make It both solid and liquid at the very same time.

It was thought that the inner core was solid and made up mostly of iron, providing a magnetic field that shields the Earth from solar radiation.

But now, new research has suggested that a mixture of hydrogen, oxygen, and carbon make it neither solid nor liquid.

This is called a “superionised” state, another state of matter like a solid, liquid or gas but with particular differences.

The study by researchers from the Institute of Geochemistry at the Chinese Academy of Sciences (IGCAS) was published in the journal Nature.
