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 ...

In a groundbreaking scientific achievement, researchers have successfully drilled the deepest-ever core sample from Earth's ...

The finding of enriched intraplate mantle-derived magmas appearing approx. 300 million years after the onset of modern plate tectonics provides important insights into the processes, driven by ...

as modern imaging techniques have not been able to identify convection currents within the mantle that are large enough to move tectonic plates. As a result this theory has been largely discredited.

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

Plate tectonic theory is the ... came up with the theory of convection currents and he said that as a substance is heated its density decreases and it rises until it cools sufficiently to sink again.

It’s often taught that Earth’s rocky tectonic plates sit on top of a syrup-like bed of viscous rock, known as the mantle, that moves along with those plates like a conveyor belt. This is ...

Cratons are fascinating yet enigmatic geological formations. Known to be relatively stable portions of the Earth's ...
