The supercontinent cycle describes the episodic assembly and dispersal of Earth’s continental masses over intervals of roughly 400–600 million years. At its heart lies a dynamic interplay between ...

Numerical modelling of mantle convection dynamics provides a virtual laboratory for probing the slow, heat-driven circulations that shape Earth’s interior and surface evolution. By solving the coupled ...

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 ...

Slow roiling convection currents deep within Earth's mantle, which are associated with the movements of tectonic plates, also deform the material of the mantle itself. Now, a new study in The Seismic ...

Forbes contributors publish independent expert analyses and insights. David Bressan is a geologist who covers curiosities about Earth. An international team of researchers investigated how Earth’s ...

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 ...
