Research led by the UofAlabama has found a new layer between the Earth’s core and mantle – a sunken ocean floor – that may play a key role in how heat escapes the core itself. 🌎
“We are finding that this structure is vastly more complicated than once thought,” said UA geological sciences professor Dr. Samantha Hansen, one of the research paper’s co-authors.
The area of research is “roughly 2,000 miles below the surface” where “Earth’s rocky mantle meets the molten, metallic outer core,” the research report says. And the changes “in physical properties across this boundary are greater than those between the solid rock on the surface and the air above it.”
