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 ...
His idea was based on mantle convection. At the ridges, ... There is also much climate evidence supporting continental drift, most notable of which is glacial activity.
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 ...
In a 1928 volume, Arthur Holmes proposed a possible answer: convection of rock in the mantle could drag the plates around. This ended up being the dominant explanation when plate tectonics was ...
Continental drift was a revolutionary theory explaining that continents shift position on Earth's surface. The theory was proposed by geophysicist and meteorologist Alfred Wegener in 1912, but was ...
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.
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 ...
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 ...
