The crust of volcanically active Venus could be churning with convection currents just like the Earth's mantle. This is the conclusion of researchers from the Washington University in St. Louis, who ...
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 ...
The possible causes of convection in the Earth's mantle are examined, and it is concluded that radiogenic heating together with thermal conduction is most likely to provide the driving force for any ...
A study proposes that imbalanced forces and torques in the Earth-moon-sun system drive circulation of the whole mantle. The new analysis provides an alternative to the hypothesis that the movement of ...
This is a preview. Log in through your library . Abstract Numerical models demonstrate that small-scale convection develops in the upper mantle beneath the transition of thick cratonic lithosphere and ...
Researchers have demonstrated in the lab how well a mineral common at the boundary between the Earth's core and mantle conducts heat. This leads them to suspect that the Earth's heat may dissipate ...
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, ...
Earth's surface is broken up into large plates that rub against each other, causing earthquakes, volcanoes and large mountain ranges. But how unique is our planet's geology? When you purchase through ...
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 ...
IT has become clear in recent years that there is a formidable case for continental drift. The most convincing single piece of evidence comes from palæomagnetism 1, but this is amply supported by a ...
