We can’t get samples from either of them, so these conclusions are based on models of the way convection drives circulation within the mantle. The team thinks the fact the two LLVPs are on almost ...

The mantle of the Earth, up to 1,800 miles (2,900 kms) thick and 84% of the Earth's volume, was assumed to be a simple ...

Beneath the vast expanse of the Indian Ocean, a strange phenomenon has puzzled scientists for decades—a massive gravitational ...

By combining a model of mantle convection, including a reconstruction of how tectonic plates have moved over the Earth's surface over the last billion years, the study has been able to show that ...

This movement is driven by the very slow creeping motion of Earth's mantle, called convection, which carry heat from the interior to our planet's surface. Researchers believe that convection in ...

Two enormous, supercontinent-sized 'islands' buried deep within the mantle ... mantle convection with a reconstruction of the last billion years of tectonic plate movements across Earth's surface.

Whether convection in the Earth's mantle extends through its entire depth or if the mantle is layered has long been debated. Recent research suggests that spatially and temporally intermittent or ...

The Earth is made up of different ... it is the plates that drive the convection. Slab pull occurs where older, denser tectonic plates sink into the mantle at subduction zones.

Beneath the Indian Ocean lies a 106-meter gravity hole, caused by ancient mantle plumes and vanished oceans. Scientists trace ...

My research group develops geodynamic models to relate laboratory-based rheologic and petrologic models to the large-scale behavior of the Earth. We apply these models to a range of problems, ...
