Earth’s Core not solid or liquid as we have long believed, but something “highly abnormal”, scientists claim. In fact, they believe the Earth’s core was formed from a mysterious mixture of elements that makes it somewhat solid and slightly liquid.
Professor He Yu of the Institute of Geochemistry of the Chinese Academy of Sciences, who led the research, said experts call this condition of the Earth’s core a “superionic state”.
Deep in the Earth’s core, lies a mixture of “lighter” elements, in addition to a very hot solid and liquid state. These include molecules of hydrogen, oxygen, and carbon, which revolve in an area shaped like an iron lattice.
“This is very abnormal. The solidification of iron at the boundary of the inner core does not change the mobility of this light element, and light elemental convection continues in the inner core,” said Professor He Yu as quoted from The Sun.
Temperature Earth’s core estimated to be over 5,500 degrees celsius, which is roughly the same as the scorching heat that can be felt on the surface of the Sun.
Scientists cannot study the Earth’s core directly to make their findings. So, they turned to another way by utilizing earthquake data.
However, the discovery left more questions than answers. Many questions make you more curious, wondering why is it like this? But at the very least, the research, published in the journal Nature, could provide new insights into Earth’s magnetic field.
“I think more research is needed to elucidate other seismic features, such as seismic anisotropy, in you in Earth,” kata Profesor Yu.
