: In this paper, a few problems of the application of geodesy to interior physical stu dy of the earth are reviewed. The postglacial rebound obtained by means of geodetic observation is an important basis for understanding the inelasticity of the mantle; Using the undulation of the geoid we can check the density anomaly distribution in the subdu-ction zone and lower mantle; The detection of nearly diurnal wobble frequency of the earth provides constraint for core-mantle flattening.
