Continental displacements of thousands of kilometres point to flow patterns in the mantle of similar dimensions. As creep depends exponentially on temperature and as it is known that the temperature of the crust increases rapidly with depth, we can in this context suppose the mantle to have a sharp transition between a rigid crust and a fluid mantle at 50 to 100 km depth. Recently the coefficients of the tesseral harmonics of the geopotential from satellite observations have been determined… 
Speculations on the Thermal and Tectonic History of the Earth
Summary The connection between the Earth’s thermal history and convection in the mantle is exploited to elucidate the early evolution of the Earth. It appears probable that convection extending over
Convection in the earth's mantle: towards a numerical simulation
Plate tectonics provides a remarkably accurate kinematic description of the motion of the earth's crust but a fully dynamical theory requires an understanding of convection in the mantle. Thus the
Speculations on the Consequences and Causes of Plate Motions
Summary Plate theory has successfully related sea floor spreading to the focal mechanisms of earthquakes and the deep structure of island arcs. It is used here to calculate the temperature
Planform of mantle convection beneath the Pacific Ocean
The correlation between variations of the bathymetry and of the geoid in the Pacific Ocean suggests that both are the surface expression of mantle convection. The planform of the convection which is
