Where the Earth’s core meets the mantle ... One relatively early discovery was that the lower mantle is not consistent where ...

Giant regions of the mantle where seismic waves slow down may have formed from subducted ocean crust, a new study finds.

A new study of decades worth of seismogram data shows that the surface of Earth’s iron and nickel core is more malleable than scientists thought.

Surprising differences in the two so-called Large Low-Velocity Provinces may risk instability in Earth's protective magnetic ...

Deep within Earth’s mantle lie two enormous, continent-sized structures known as LLVPs. Scientists once believed these ...

Continent-sized structures of mineral protruding from the lower mantle towards Earth's outer core may be contributing to an ...

"Our new results suggest that for most of Earth's history, convection in the mantle was stratified into two distinct layers, namely upper and lower mantle regions that were isolated from each ...

Indian scientists have uncovered the possible cause behind the Indian Ocean Geoid Low (IOGL), the lowest geoid anomaly on ...

Continent-size islands deep inside Earth's mantle could be more than a billion years old, a new study finds. Known as large low-seismic-velocity provinces (LLSVPs), these blobs are both hotter and ...

Beneath the Indian Ocean lies a 106-meter gravity hole, caused by ancient mantle plumes and vanished oceans. Scientists trace ...

lower crust and continental lithosphere layers plus a relatively unstable thermal boundary layer. Beneath the continent is the asthenosphere, the ductile upper layer of Earth’s mantle.
