Scientists have just discovered a strange rock layer stretching about 20km under the Bermuda Islands, with a thickness never recorded anywhere else in the world.
This discovery is giving scientists a headache, because the rock layer could represent a new layer in the Earth's structure.
The rock layer is located deep under the Bermuda Islands, a famous location in the mid- Atlantic Ocean and is being actively studied by scientists.
According to the study's lead author, seismologist William Frazer of the Carnegie Institute of Sciences, Washington, D.C., the ocean's crust is typically covered. However, Bermuda's case is completely different.
The discovery comes as scientists have recently proposed new theories to explain the mystery of the Bermuda Triangle, including a theory of geological phenomena that appear as water fired in the bathroom.
According to traditional understanding, the Earth is made up of 4 main layers of the shell (where humans live), the layer, the outer core and the inner core.
Most of the knowledge about the structure of the Earth comes from research on the evasion of water flowing up deep underground through volcanic explosions. However, Bermuda does not appear to follow this rule.
Mr. William Frazer pointed out that usually behind the bottom of the ocean lining is the layer below. But in Bermuda, there is another layer under the shell, right in the Bermuda plateau.
He believes that this unusual rock layer could be the key to solving the long-standing mysteries related to Bermuda.
Bermuda is now located in the rising sea floor, although the most recent volcanic explosion in the area occurred about 31 million years ago.
The new discovery suggests that the landslide may have pushed soil and rock from the coating onto the shell, then cooled and became stationary. This process forms a raft-like structure, causing the ocean floor here to rise to about 500m.
Place like Bermuda helps us distinguish between normal geological processes on Earth and rare extreme phenomena on the planet, Frazer said.
This is not the first time that scientists have questioned whether the Earth can possess previously unknown strata. In 2021, geophysicist Joanne Stephenson of the Australian National University and his colleagues found evidence that the Earth's core could consist of two separate layers.
The team has found signs that the structure of iron in the Earth's core may have changed, suggesting that our planet has gone through two different cooling periods in history.
