Some of Earth’s Surface Water Might Be Traveling Down to the Outer Core

<p>Researchers behind the paper published in November used high pressure experiments at the Advanced Photon Source of Argonne National Lab in Illinois and Germany&rsquo;s PETRA III of Deutsches Elektronen-Synchrotron to replicate the extreme conditions around Earth&rsquo;s core.</p> <p>In their experiments, they tested how surface water at the mantle-core boundary would react to the extreme heat and pressure around the core. What they found was that the water chemically reacted with core materials, forming a hydrogen-rich, silicon-depleted layer that acted like a film surrounding the outer core. The reaction also forms silica rich crystals that rise into the mantle. This results in a dense, silica rich area at the bottom of the mantle. The findings of the experiments gave geologists answers about a mysterious layer of Earth&rsquo;s interior known as the E-prime layer.</p> <p><a href="https://beccajean.medium.com/some-of-earths-surface-water-might-be-traveling-down-to-the-outer-core-f8e2d94827cf"><strong>Read More</strong></a></p>
