The only adequate mechanisms for continental drift which have yet been suggested are based on the activity of convection currents in the Earth's mantle. You have full access to this article via ...

THE study of palæomagnetism has necessitated the contemplation of continental drift and the most plausible explanation appears to be convection in the mantle 1,2. It has been assumed that the ...

Drifting of the large tectonic plates and the superimposed continents is not only powered by the heat-driven convection processes in the Earth's mantle, but rather retroacts on this internal ...

The film discusses the theory of plate tectonics and continental drift, explaining how the Earth's surface has changed over time. It highlights the concept of tectonic plates moving due to ...

Mantle convection is responsible for the movement of tectonic plates on Earth's surface. It is basically the circulation of material in the mantle caused by heat from Earth's core.

Continental crust is generally higher in silica, which makes it less dense. This low density makes continents too buoyant to be pulled back into the mantle and they remain floating near the surface.

However, scientists have had little practical understanding of how the presence of solid objects affects convection. Now, Jun Zhang and Bin Liu have done a simple table-top experiment that reveals ...

Ancient Earth’s hot interior created 'graveyard' of continental slabs Date: August ... Benjamin Z. Klein, Oliver Jagoutz, Mark D. Behn. Archean crustal compositions promote full mantle convection.

The South Atlantic breakup, which separated the African and South American continents, is the basis of the continental drift hypothesis and has been widely studied. However, the driving forces ...

Mantle convection is responsible for the movement of tectonic plates on Earth’s surface. It is basically the circulation of material in the mantle caused by heat from Earth’s core.

Continental crust is generally higher in silica, which makes it less dense. This low density makes continents too buoyant to be pulled back into the mantle and they remain floating near the surface.

This makes Greenland one of the top contributors of mass being transferred to the oceans, causing sea level to rise and, consequently, a drift in Earth’s spin axis.
