Why in the News?<\/b><\/h2>\n

Researchers from Arizona State University and an international team discovered the origin of the previously known E prime layer in the Earth’s interior<\/strong>, which until now remained a mystery.<\/span><\/p>\n

What is the E prime<\/b> layer?<\/b><\/h2>\n

The E prime layer is a distinct layer formed at the <\/strong><\/span>outermost part of Earth’s core<\/strong>. <\/span>This layer is formed by<\/strong><\/span> surface water penetrating deep into the planet over billions of years<\/strong>.<\/span><\/p>\n

Composition:<\/b> It is a <\/span>hydrogen-rich and silica-depleted layer.<\/span><\/p>\n

How is the E prime<\/b> layer formed?<\/b><\/h2>\n

Over billions of years, surface water has been transported deep into the Earth by descending tectonic plates.<\/p>\n

Upon reaching the core-mantle boundary about 1,800 miles below the surface, this water chemically reacts with core materials.<\/span><\/p>\n

This reaction leads to the formation of a hydrogen-rich, silicon-depleted layer at the outer core, resembling a film-like structure. This is known as the <\/span>E prime layer.<\/span><\/p>\n

The reaction also generates silica crystals which rise and integrate into the mantle, impacting the overall composition.<\/span><\/p>\n

What is the significance of this study?<\/b><\/h2>\n

1) These findings also have significant implications in understanding Earth\u2019s internal processes<\/strong>, heat generation and plate tectonics.<\/span><\/p>\n

2) These findings point to a dynamic core-mantle interaction<\/strong>, suggesting substantial material exchange.<\/span><\/p>\n

3) It also indicates<\/span>\u00a0a more extensive global water cycle<\/strong> than previously acknowledged.\u00a0<\/span><\/p>\n
