New Magma Layer Found Deep in Earth's Mantle?

Couple of days ago, scientists found out there was a layer in Earth, which was unknown until now. This is a layer of hot liquid magma, trapped in the Earth’s formation on about 1,800 miles below our feet, new research shows.
Research states that once upon a time, the solid layer beneath the Earth’s crust housed an ocean of magma, and that some of the remains are still there. "Some models consider the [early] Earth to have been completely or largely molten, and people are looking for possible remnants or relics of this molten state," said study co-author Guillaume Fiquet.

"Some models consider the [early] Earth to have been completely or largely molten, and people are looking for possible remnants or relics of this molten state," said study co-author Guillaume Fiquet.
As these models suggest that as the Earth hardened, there were still parts which stayed molten, probably in the mantle-core c boundaries. In a new experiment, Fiquet and other scientists showed what would happen to the minerals in the Earth’s mantle, if they were exposed to the unbearable heat and pressure of that boundary between the mantle and the core of the Earth. Their findings not only explained about the structure of the earth, but also about how some volcanoes, might get their magma from places very close to the core to the Earth.
Based on the way seismic waves travel through Earth, scientists believe that the Earth has a solid core made of solid iron ball, surrounded by a layer of molten hot iron. Above the core there is the solid lower mantle, the upper mantle, and the Earth’s crust. There is no way to take a sample from the insides of the Earth, so there is no way for people to know for sure if the mantle's boundary rocks are solid or liquid. But scientists have long recorded the seismic activity; the sudden drops in the speed of seismic waves when it comes near the mantle-core boundary, thanks to this, scientists speculate that, this boundary is partially melted.
This article interested me, because I think that it’s really interesting to know what makes up the Earth’s core, and insides. I personally like science, I have always been a big fan of science, and I think that just knowing how the Earth is made is interesting, because we really need to know about where we live. We really don’t know how it formed itself or whether it’s molten rock, or solid rock. I think that it’s really important to know about this. A connection I could draw to my life is that until now, I knew about the structure of the Earth one way, and now they discovered this layer, that might or not be there, and it will change the model I once knew. There is not much that can be drawn to my life with this article actually, but mostly that I like it because I like science.
Understanding how the earth is composed can help us understand better how it works. There are many connections that you can make but Im glad you have a broader understanding from this article. Good Job. Also you do not need to put your name and other information at the beginning. I know this is your site. Maybe include a picture next time.
