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

Heat transport in the Earth's mantle and in the atmosphere is probably not as effective as previously thought. Not only in the Earth's mantle, in the atmosphere and in the outer layers of the Sun ...

While scientists expected the mantle to cool over time as heat left over from Earth’s formation and from radioactive decay dissipates, this degree of cooling was surprising. Plate tectonics is ...

As they report Wednesday in Nature, new clues suggest that the oxidation change is a sign that Earth’s mantle rocks were melted in extreme heat and then persisted through billions of years.

The current total heat flow at the Earth's surface — 46 ± 3 terawatts (10 12 J s −1) — involves contributions from heat entering the mantle from the core, as well as mantle cooling ...

Earth's hot, gooey center and its cold ... Previously, researchers would make models of heat-driven convection in the mantle that matched observations of the real mantle pretty well, but didn ...

as well as rare-earth elements. Such radioactive elements have long been thought to produce about a third of the heat circulating in the lower mantle (the other two-thirds is left over from the ...

Figure 1: Speeds of seismic waves in the Earth, showing the major discontinuities at 410 and 660 km depth, and the D″ layer at the base of the mantle. The object of this Review is initially to ...

they must be restricted to the crust and mantle. The latest research from the Japan-based KamLAND collaboration, which uses neutrinos to track heat signatures from within the Earth, says that ...

For decades, scientists have theorized that the movement of Earth’s tectonic plates is driven largely by negative buoyancy created as they cool. New research, however, shows plate dynamics are driven ...

We found big chunks of the impactor Theia.” With those five words to The New York Times, Caltech geophysicist Qian Yuan ...

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 ...
