It is known that the Earth's magnetic field is produced by convection currents of an electrically conducting iron-nickel alloyin the liquid core, about 3,000 kilometers below the earth's surface.

are where tectonic plates pull apart due to convection currents in the mantle. Most constructive plate boundaries are found on ocean floors. As the plates move apart (very slowly), magma ...

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 ...

Previous theories have suggested that the movement of these tectonic plates is likely caused by convection currents in the molten rock in Earth's mantle below the crust. This idea would explain ...

Using dating model we learned:. Convection currents within the mantle contribute to plate movement. The mantle's convection currents pdf the location of divergent boundaries and trenches.

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.

The researcher did, however, note we didn't know enough to pinpoint how long it will take for convection currents to stop altogether. READ MORE: Earth’s interior is cooling faster than expected ...
