How plate tectonics works The driving force behind plate tectonics is convection in the mantle. Hot material near Earth's core rises, and colder mantle rock sinks. "It's kind of like a pot boiling ...

An unexpected find in tiny crystals hints that the Earth's mantle may not quite behave as has been believed for nearly a century.

Additionally, a large region of upper mantle material, known as a "large mantle wedge," developed between the advancing slab ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied.

John Sclater, a geophysicist at UC San Diego’s Scripps Institution of Oceanography and a member of the first wave of ...

Convection is the process that drives hot currents ... which can't sink into the Earth's dense mantle. For at least 80 million years the oceanic Indian Plate continued its inexorable collision ...

The North China Craton (NCC) is a very old and stable geological structure, experiencing deformations since the Mesozoic era.

The mantle is split up into two domains — the African and the Pacific — that emerged when supercontinent Pangaea broke apart. When you purchase through links on our site, we may earn an ...

On present-day Earth, plate subduction continuously modifies the chemical composition of the convecting mantle, and various mantle sources linked to these processes have been widely studied.

“This study provides a first present-day example of how a cold downwelling from above is breaking up a deep mantle blob,” says Sanne Cottaar, a professor of global seismology at the University ...

A mysterious find on Easter Island, investigated by a team of geologists, suggests that the Earth's mantle seems to behave differently than once thought. Geography textbooks describe the Earth's ...
