The Earth is made up of different layers: Therefore, instead of tectonic plates moving because of the convection currents, evidence suggests it is the plates that drive the convection. Slab pull ...

The plates make up Earth's outer shell, called the lithosphere. (This includes the crust and uppermost part of the mantle.) Churning currents ... tectonic boundaries: convergent, where plates move ...

These continents are still on the move today. Exactly what drives plate tectonics is not known. One theory is that convection within the Earth's mantle pushes the plates, in much the same way that ...

Tectonic plates are able to move because the Earth's lithosphere has greater strength than the underlying asthenosphere. Lateral density variations in the mantle result in convection. Plate ...

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

The plates fit together like jigsaw puzzle pieces far beneath our feet. Tectonic plates move - usually very slowly - and this broke Pangaea up into separate parts, eventually creating the ...

This advanced undergraduate textbook provides a thoroughly modern overview of plate tectonics and is the perfect resource for a capstone geology course. It presents plate tectonics as a multifaceted, ...

The mid-ocean ridges mark the lines along which the Earth is turning itself inside out through the process of plate tectonics. Advances in technology are helping to reveal the intricate details of ...

Researchers found the ghostly white critters sandwiched beneath slabs of solidified lava along the East Pacific Rise, a fast-spreading ocean ridge where several tectonic plates meet off the coast ...
