Science is a great ally for the world’s discoveries, not only of what is in the galaxy, but also of what is beneath our feet: the Earth’s core. In this way, an inner layer of the Earth was exposed, and this novelty is much discussed in the scientific community.
The innermost layer of the Earth
team of Seismologists (Researchers who study the movement of the Earth’s surface) from the Australian National University were responsible for discovering a new layer in the Earth’s core.
Among the information they were able to uncover is the fact that the layer has a diameter of about 650 km and is composed of dense iron.
This information is very important for us to understand how the Earth’s core works and what materials this structure is made of.
In addition, it should be noted that this is the deepest layer, which has already been scientifically proven. In the past, what existed in relation to this were guesses as to what might exist and the possible size.
Why study the Earth’s core?
Many people end up not realizing the importance of such discoveries, because the influence of the Earth’s core is not well explained.
The interior of the Earth is responsible for many natural phenomena that directly affect the surface of our planet, such as earthquakes and volcanoes.
Understanding more and more how they operate there, it becomes easier for researchers to have some prediction of these events so that the population of the affected area is warned.
How was it discovered?
This new layer was discovered based on information from more than two hundred earthquakes of magnitude greater than magnitude six that occurred in the past decade. Remember that the Richter scale is scored from one to nine.
In doing so, the team of seismologists who made the discovery identified unusual behavior in seismic waves that reached the deepest layers of our planet’s core.
What is the technology used?
Of course, none of this would be possible if there were no advanced technology like the backing of researchers.
Therefore, they performed seismic wave analysis using modern technology. With this, new assumptions are made, such as growth in the core.
