Abstract: The proto-kinetic mechanism of crust movement, a crustal body deformation, is discussed. It is characterized by the earth thermal environment as a condition, solid state material deformation as a foundation in the form of mass deformation and mass transport, and finally resulted in crust movement through the volume changes of the earth. This paper discusses the shaping process, thermal environment, mass state variable, incremental variable, the earth body variable, crustal motoricity, the relationship between thermal alteration effect and crust or crustal body deformation mechanism. And the data of the earth are determined, including the coefficient of cubic expansion (0.097), the mass state variable or incremental variable (160×108 km3), the body deformation and velocity (2 mm/100 a), the expanding and subducting velocity of oceanic lithosphere (32×104 m2/a)and entry pressure of crust movement.
