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.

This topic video looks at how tectonic plates move and introduces the debate over the theories of 'convection currents' versus 'ridge pull and slab push'. It is part of the AQA GCSE Geography course - ...

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

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 ...

The team studied the mineral zircon from two of the oldest pieces of intact crust—dating 4.0 to 2.7 billion years old—and discovered that ancient plate tectonics, or how the continents move ...

In the case of external anomalous or unwanted electromagnetic solicitations, the plates are interested by induced currents. These currents couple with electrically active parts of the system ...
