Research on hidden structures deep within Earth’s mantle challenges theories about our planet’s middle layer and could ...

Since the late 1960s, when plate tectonics and slow, creeping convection of the rocky mantle became accepted, geoscientists have been debating whether convection extends from the surface to the ...

Plate tectonics give Earth its mountains, earthquakes, continental drift and maybe even helped give rise to life itself. But do other planets in the solar system have them too?

"Subducting tectonic plates that end up in the slab graveyard ... also imply that they are not involved in the convection or flow of the mantle, meaning that the mantle may not be as well-mixed ...

To find out, the team used whole-Earth oscillation data from 104 past earthquakes to create a detailed 3D model of the upper ...

The ocean plate was once the seafloor of Neotethys — an ocean that formed when the supercontinent Pangaea broke up into a ...

Without the convective mantle, there wouldn't be enough energy to move the plates. But convection on its own isn't enough to guarantee that a planet or moon will exhibit plate tectonics.
