According to current knowledge, therefore, an influence of plate tectonics and mantle convection on the Earth's magnetic field seems quite possible.

Until now, the answer was thought to be unrest in Earth’s mantle. Under intense heat and pressure, superheated magma rises in what are known as convection currents, pushing the tectonic plates ...

Plate tectonics move because they are carried along by convection currents in the upper mantle of the planet (the mantle is a slowly flowing layer of rock just below Earth's crust). Hot rock just ...

The new analysis provides an alternative to the hypothesis that the movement of tectonic plates is related to convection currents in the Earth's mantle. Convection involves buoyant rise of heated ...

The theory of convection in a medium with internal heat generation is discussed semi-quantitatively. It is concluded that a mantle convection pattern based on calculations of marginal stability in an ...

They are thought to move around by convection currents in the mantle, but whether those currents exist in the whole mantle or just the upper part is still an open question, Murthy said.

They are thought to move around by convection currents in the mantle, but whether those currents exist in the whole mantle or just the upper part is still an open question, Murthy said.

Many geophysicists believe that this cyclical pattern could be related to regular disruptions in the convection currents in the Earth’s mantle, upon which the continents float. However, scientists ...

Here convection currents push mantle material together, forming plumes of less dense rock that eventually will start rising and heating up regions of the mantle.

Its apparent presence in the mantle, researchers have shown, implies that the mantle’s convection currents (in which cooler rock sinks and hotter rock upwells, taking some of the earth’s inner ...
