A review for the continental drift theory from the mid-ocean ridge——Give consideration to the expanding Earth hypothesis;

This paper tries to expound systematically imaginal thinking effect in the earth science from guessing the earth shape to verifing,from breeding of the theory of continental drift toputting forward,from developing historical process of geology to having thinking ability of the wockers in the earth science and so on.

Brief evolutionary history of the earth and continental drift used in biogeographical distribution;

In this paper, a simple dynamical model for simulating continental drift is formulated based on the angular momentum exchange between inner solid core and outer liquid core during the early stage of the Earth formation.

Through introducing the new conception of moving objects creating u-field,themechanism of the Eartb’s reduced spin for a long time and the continental drift are discussed inthis paper.

The force to drive crustal move ment include the public turn s inertia force and the private turn s force with identical velocity of the earth, inter plane lary gravitation and gravity, their synthetic force is the true driving force of continent drift.
