The convection currents in the mantle of the Earth are created when hot molten lava comes to the Earth's crust and then going down below the crust... See full answer below.Become a member and unlock all Study Answers Start today. Try it now Create ...
The effect of the frictional heating in the heat equation becomes comparable with the conduction terms along the inner boundaries of the boundary layers of the cellular convective current The frictional heating term exceeds the heat conduction term near the vertical boundaries of the convection cell. ...

What are convection currents in the Earth's mantle? Heat and Density: Hot particles are less dense than cold particles. This applies to air, water, and rock in the mantle of the Earth. Since warmed particles move faster, there is more space between them. The wider space between particles ...
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.doi:10.1038/202583b0Bott, M. H. PNature Publishing Group UKNatureBott, M.H.P. (1964). Convection in the earth's man- tle and the ...
JEFFREYS has raised an interesting objection 1 to the possibility of convection or steady-state creep occurring in the upper mantle. Lomnitz has shown 2 that the logarithmic stress–strain relationship observed in igneous rocks in the laboratory may be used to derive an attenuation coefficient for ...
