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

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.

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

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

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 ...

These findings suggest more diverse origins for these anomalies in Earth's lower mantle.' Earth is made up of three layers – the crust, the mantle and the core, which was later separated into ...

"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 ...

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.
