The Earth would have the remains of an ocean in what is now the core, according to a new study

Almost 3 thousand kilometers from the surface, in the interior of the Earth, may be the remains of an ocean. This is the result of a new investigation, this time carried out by American scientists.

The study titled Subducted materials distributed globally along the Earth’s core-mantle boundary, it counted Samantha Hansen, Edward Garnero and Sebastian Rost among the investigators.

It was published on the portal Science Advances.

According to scientists, there are thin but dense layers of material that lie between the mantle boundary and Earth’s core. This material would have formed the ocean floor, before being pushed into the mantle by the continental plates.

Hansen and his colleagues analyzed waves from 15 seismic stations buried in Antarctica, coming to that conclusion.

“Using a recently developed seismic analysis approach,” the authors note, “we found variable and widespread ULVZ along the core-mantle boundary (CMB) beneath a largely unsampled portion of the southern hemisphere.”

“By analyzing thousands of seismic recordings from Antarctica,” Garnero explained, “our high-frequency imaging method definition found fine anomalous zones of material in the CMB in all the places we tested.”

The importance of the Earth’s core for our life

The Earth’s core is divided into two parts: one internal and one external. While the internal one is a sphere with a radius of more than 1,200 kilometers, made up of iron and nickel, the external one is a liquid layer that surrounds it, with a thickness of 2,200 kilometers.

are the temperature, As NASA explains, It is hotter than the surface of the Sun, reaching 6 thousand degrees Celsius.

Thanks to its movement and the rotation of the Earth the magnetic field is created, It protects us from space radiation and solar winds.

The material evaluated by the researchers, according to Very interesting, it varies from a few kilometers to tens of them. “This suggests that we are seeing mountains in the core, in some places up to five times higher than Mount Everest,” Hansen and his colleagues say.
