- The formation of new enigmatic layer – E prime layer – at the outermost part of Earth's core is a result of "surface water penetrating deep into the planet.
- Tectonic plates carrying surface water have transported it deep into the Earth over billions of years.
- Subducted water reacts chemically with core materials under high pressure.
- This reaction leads to the formation of a hydrogen-rich, silicon-depleted layer at the outer core.
- Silica crystals generated by this process ascend and blend into the mantle, impacting the overall composition.
- These modifications in the liquid metallic layer could potentially result in reduced density and altered seismic characteristics.
