Continental drift is a concept familiar to many, referencing the movement of Earth's continents due to shifting tectonic plates over millions of years, splitting one globe-spanning supercontinent into ...

NASA/Theophilus Britt Griswold. Contrary to Earth, present-day Mars has little to no volcanic or tectonic activity.

Mars has northern and southern hemispheres like Earth, but their defining characteristics are markedly different, a phenomenon known as Martian dichotomy. The Southern Highlands are older, higher in ...

Researchers may have found a missing link in how Earth's mantle gets wet: newly discovered iron minerals that can store water at the extremely high temperatures and pressures present near our planet's ...

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 ...

Image from a global simulation of Earth's mantle convection enabled by the NSF-funded Stampede supercomputer. The Frontera system will allow researchers to incorporate more observations into ...

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 ...

There is a lot that scientists don’t know about the mantle, the partly molten, partly solid layer of Earth that makes up 84 percent of the planet’s volume. We know that it's composed of vast cycling ...
