Ancient Structure Taller Than Mt Everest Found Wrapping Earth’s Core

According to the findings published in the journal Science Advances, an ancient structure layer taller than Mt Everest has been found wrapping Earth’s core between the core and the mantle.

Earth’s structure was divided into four layers crust, mantle, outer core, and inner core, but then a fifth layer was discovered sitting within the center of the inner core. Researchers have now found a unique, dense, yet thin layer wrapping the core, shedding more light on the inner world of the planet.

Researchers at the University of Alabama revealed a layer between the core and the mantle that is likely a sunken ocean floor seen only in isolated patches previously. The data revealed that the ancient structure may cover the core-mantle boundary (CMB) beneath the surface.

The findings published in the journal Science Advances state that the layer was discovered beneath a largely unsampled portion of the Southern Hemisphere.

Roughly 2,000 miles below the surface, Earth’s rocky mantle meets the molten.

“While less than 20 per cent of the CMB has been surveyed for the presence of these ultralow velocity zones, seismic wave scattering studies have identified globally distributed small-scale heterogeneities in the lowermost mantle,” the paper read.

According to a study published on Monday in Nature Geoscience, the Earth’s core may be reversing direction on a regular cycle.
