A new study suggests that Earth's true core could be a ball of iron-nickel that scientists hadn't uncovered yet.
. But scientists have never been able to prove without a shadow of a doubt what the Earth’s true core is made of.comes in, or at least, that’s where it tries to come in. The study was published this month, and focuses heavily on uncovering what the Earth’s true core is made out of it. According to the findings published in the paper, it appears that scientists believe it is made up of a 400-mile-wide ball of iron, which is actually a completely new layer that scientists hadn’t uncovered yet.
Because the Earth’s core is so deep, and hidden within a molten layer of rock, it’s pretty much impossible to dig down and simply discovery it for ourselves. That’s where seismic waves come in, as they can help us measure what kind of substance the waves are passing through when they occur. The researchers say the Earth’s true core is iron because of the “ricochets” they uncovered.
It’s an intriguing discovery, and one that the paper outlines very well. If it does indeed prove true that the Earth’s true core is a ball of iron, then it could help scientists better understand how our planet came to exist in the first place.
