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 ...

A ‘ghost plume’ identified deep in the mantle beneath Oman suggests there may be more heat flowing out of Earth’s core than ...

A phase change in post-perovskite materials at the so-called D” discontinuity is also evidence for long-predicted slow, convective flows in the mantle itself ...

Scientists found a rhythmic mantle plume beneath Ethiopia is slowly tearing Africa apart - hinting at the birth of a new ...

Mars 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.

Researchers believe that convection in the mantle, which started shortly after Earth's formation 4.5 billion years ago, occurs at the scale of the whole mantle.

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 ...

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 ...

The depths of the Earth still hold many surprises. A team of scientists has discovered that objects move horizontally in the Earth's mantle, nearly 1,864 miles (3,000 km) beneath our feet.

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 ...
