Study finds Earth’s innermost layer is a 400-mile-wide ball of iron

The center of the Earth has always been a mystery to scientists. The latest research has come out with a theory that brought science closer to the truth of the core of the Earth. The study suggests that the Earth’s innermost core is a distinct ball of iron.

Underneath the layers of Earth, Crust, The mantel, and the outer core, made up of molten liquid, lies a solid metal center. According to the new study that was published on Tuesday in the journal Nature Communication, it was published that the hidden layer or “an innermost inner core” is present underneath all the layers.

Huge research shows that the Earth has five layers instead of four. This study report retrieved excellent details about the oldest mystery related to your home planet. Scientists can find out new information to solve unknown questions about the layers of the earth.

It was suggested by several geoscientists that the Earth has an additional layer with it. This statement was given almost 20 years ago. Now a recent study came out with the reports that consisted of data of the seismic wave earthquake measurement that was passed through the Earth’s core. Through this, the scientists have detected and got confirmed data about the innermost core.

In simple words, the seismic waves are vibration waves that travel through the Earth’s surface along with its inner layers. This happens due to natural disasters like earthquakes, Volcanoes eruptions, etc.

Dr. Thanhson Pham, the co-author of the study, a well-reputed seismologist and postdoctoral at the Australian National University in Canberra, gave his opinion about the report. He said that they had studied the earthquake’s seismic waves traveling from one side of the earth to another in a to-and-fro motion. This motion continued almost five times, which gave them ample time to observe.

Dr. Pham well-versed scientist in the Research School of Earth Sciences; he shared his critical views and theories about the earth and its layers, which come of great help to the readers and the science society. This layer remained unidentified by the scientists as the distinction between the upper layer was not made. The core and the innermost core are pretty similar, and this kept the earlier studies restricted to four layers.

It has been said this innermost inner core is 400 miles wide, in other words, almost 644 kilometers of metal. This core part has an outer shell made up of iron-nickel along with combinations of other metals.
