The material of internal earth experienced differentiation and adjustment under the dynamic processes and deep and shallow of earth exchange materials and energy strongly, which result in the formation of mountains， basins， minerals， earthquake and volcanic hazards. Geodynamic is highly valued by earth science community, and many hypotheses have been proposed, such as earth contraction theory， earth expansion theory， earth pulsation theory， earth rotation theory， flow theory， mantle convection theory and isostasy theory and so on, but the key question is which the force source is! The reason is that force source is at the heart of material movement in the interior of the earth.
