E-prime Layer

According to a new study, Earth core's mysterious new layer was formed due to surface water diving deep.

  • Inner Earth – It has 4 primary layers
    • Inner core (innermost layer)
    • Outer core
    • Mantle (middle layer)
    • Crust (outermost layer)
  • E-prime layer – It is the new enigmatic layer which is formed at the Earth's outer core as a result of surface water penetrating deep into the planet.
  • It is more than 60 miles (100 kilometers) thick, relatively slim compared with other sections of Earth's interior.

Impact – Modifications in the liquid metallic layer could potentially result in reduced density and altered seismic characteristics.

Significance – The transformed layer in the core holds significant implications for the interconnected geochemical processes linking surface water cycles with the deep metallic core.
