Abstract: In this paper, formation of primitive celestial bodies from nebular material with independent revolution angular momentum is studied first and discussion is stressed on following problems: the theory of material convective motion produced by heterogeneous distribution of force source in the interior of celestial body；the features and responses of the gravitational field around the earth; the relative movement features of earth’s crust to the core, which rotates around the galactic center; the relationship between the large-scale meridian horizontal movement of terrestrial crust and the galactic year, as well as their comparison to prehistoric tectonic cycle periods. It is thus confirmed that the behaviors of relative movement of the interna1 material in celestial bodies, i.e. the terrestria1 crust large scale meridian movement, is a reflection of revolution angular momentum conservation of the celestia1 body.
