Convection currents in the mantle move faster than previously predicted Ars Electronica/Flickr Convection currents in the Earth's mantle move faster than previously believed, say researchers. A study ...
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 ...

Nature: Convection in the Earth's Mantle and the Mechanism of Continental Drift
Hints from seismic tomography and geochemistry indicate that Earth's mantle is heterogeneous at large scale. Numerical simulations of mantle convection show that, if it started enriched in silicates, ...
Scientists have mapped how Earth’s deepest mantle is being deformed—and the results point to long-lost tectonic plates buried thousands of kilometers underground. Using a massive global dataset of ...
A new global seismic map shows how Earth's deepest mantle is being warped in regions where ancient tectonic plates are buried far beneath the surface. The study analyzed more than 16 million ...
Seismic waves from earthquakes have always offered a window into Earth’s hidden interior. For decades, researchers believed they had a firm grasp on how these waves revealed the rocky mantle’s secrets ...
Scientists have shown that temperature differences deep within Earth's mantle control the elevation and volcanic activity along mid-ocean ridges, the colossal mountain ranges that line the ocean floor ...
