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 ...
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 ...
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 ...
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 ...
The biggest jigsaw puzzle in the solar system has a split personality: The number and sizes of Earth's tectonic plates can flip, according to a new study. Today, the pieces of Earth's broken shell are ...
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 ...
"Convection in the crust could be a key missing mechanism." Convection processes beneath Venus' scorched surface may help explain the planet's many volcanoes, a new study reports. Venus, the hottest ...
