A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...
On a time scale of tens to hundreds of millions of years, the geomagnetic field may be influenced by currents in the mantle. The frequent polarity reversals of Earth's magnetic field can also be ...
This "virtual Earth" is the first computer model that "views" the crust and mantle as an interconnected, dynamic system, the researchers reported Oct. 30 in the journal Science Advances.
Magnetic field, mantle convection and tectonics Date: July 29, 2012 Source: ... On the other hand, processes within Earth's mantle in turn also affect the heat flow.
Questions surround the timing of the onset of Earth's mantle convection and its subsequent evolution. Numerical modelling suggests that the mantle developed in two distinct stages. Masaki Ogawa at ...
Like most of us, Earth has a lot going on under the surface — even in what may have once seemed to be its most unassuming layer. The mantle, a zone between our planet’s thin crust and the ...
Scientists found a rhythmic mantle plume beneath Ethiopia is slowly tearing Africa apart - hinting at the birth of a new ...

Mars's two distinct hemispheres caused by mantle convection not giant impacts, study claimsMars has northern and southern hemispheres like Earth, but their defining characteristics are markedly different, a phenomenon known as Martian dichotomy. The Southern Highlands are older, higher ...
A new study, using convection models, shows that Earth’s collision with the protoplanet Theia some 4.5 billion years ago, might’ve triggered early subduction in Earth’s crust.
That’s when convection takes over, as heat from the Earth’s core causes a very slow creeping motion of materials in the solid mantle and the ensuing currents carry heat from the interior to ...
