WHAT truly lies beneath Earth’s surface largely remains a mystery but scientists have just discovered a new hidden “zone”.
The previously unknown layer has remained a secret until now and is said to be 100 miles below the Earth’s crust.
The hidden layer is made up of partly molten rock.
It was revealed in a groundbreaking study that could help us to unlock some of Earth’s secrets, including how it formed.
Scientists think it could also change what we know about tectonic plates and how they move.
A team of scientists was led by Junlin Hua, a postdoctoral fellow in geosciences at the University of Texas.
They discovered the new zone and have just published a study about itin the journal Nature Geoscience.
Hua told Vice’s Motherboard: “We were amazed by how well the observation…matches our intuition.
“I was also a little surprised by how widespread it is.”
