Convection in the mantle and its effect upon the earth's gravitational field

  • David G. Ashworth


The failure of an equilibrium model to provide an adequate representation of the Earth's external gravitational field suggests that one should consider a more general hydrodynamical model for the interior of the terrestrial globe, and the most probable cause of motion, which may significantly effect the distribution of density inside the Earth, is convection throughout the mantle. In the present paper we investigate the effects of convection in the mantle on the gravitational field of the Earth and calculate the velocity of convection necessary to account for the observed characteristics of the external gravitational field.
