Scientists have discovered a hidden layer of Earth, located at a depth of 100 miles below the surface and cover at least 44% of the planet, this unknown area of molten rocks is part of the Mauric Cover (the region of the Earth is between 100 to 200 km below the surface of the earth),, Below the tectonic plates are located in the upper scarf, which is a soft end that allows the solid rock panels to move.
According to the British newspaper "Daily Mail", while this discovery is important, it breaks the old theories that molten rocks affect the viscosity of the material.
"When we think about something that melts, we think in a way that melting should play a big role in the wife's wife," said Jonlin Hua, from the University of Texas, Austin, in a statement.
Previous theories have suggested that the movement of these tectonic plates is likely to be probably caused by pregnancy currents in the molten rocks of the ground scarf.
This idea explains how solid rock panels can move smoothly under the surface, however, the University of Texas in Austin has set this theory aside.
Although it may seem to be a blow to the scientific community, the co -researcher Thorsten Becker said that this means a less difficult variable for Earth's computer models.
"We cannot exclude that local melting is unimportant," said Baker, who designs that the Gyodmodic Models of the Earth at the Texas University Institute for Jackson, said, adding: "But I believe that it drives us to see these melting notes as a sign of what is happening on the ground, and it is not necessarily an active contribution. in anything."
The idea of searching for a new layer in the ground came to Hua while studying the seismic images of the scarf under Turkey during a doctorate research, interested in the signs of partially fascinated rocks under the cortex, where he collected Hua similar photos from other earthquake stations until he had a global map of the Maurized cover.
What he and others considered anomalies was common all over the world, and appears in seismic readings wherever the Maori cover is hotter.
The following surprise came when he compared the map of melting with the seismic measurements of the tectonic movement and did not find any connection, although the molten layer includes nearly half of the earth.
"This work is important because understanding the characteristics of the Mauritan cover and the origins of its weakness is essential to understanding tectonic plates," said the participating researcher Karen Fischer, a earthquake and professor at the University of Brown.
