Gravity and heat flow observations indicate that the structural and chemical differences between oceanic and continental regions extend to depths of several hundred kilometres. A theory of continental drift must account for the maintenance of the deep structure of continents. A comparison of the figure of the Earth obtained from satellite observations with that calculated on the assumption that the Earth is in hydrostatic equilibrium demonstrates that stress differences of the order of 100 bars exist within the mantle. If these stress differences are to be maintained by convective flow, then the mantle must have an average viscosity of 1026 c.g.s.
