Since the last decade of the 20th century, scientists have been trying to establish a globle geody namic system and more understanding the mechanism of heat and material interactions between interier layers of the Earth. This paper presents analyses of core, core mantle boundry, transitional zone of mantle, upper and lower mantle, crust-mantle boundry, plume theory, manterial exchanges and rheological motion in different layers. Heat and material exchanges of interier layers of the Earth and the crust-mantle interaction are dis cussed, including underplating, delamination and partial melting processes. It is concluded that the crust-mantle interaction is a process increasing by degrees dynamically and physical chemically. The crust-mantle interaction is not only a main mechanism of continental dynamics, but also couples with orogene, mantle convection, form and evolution of basin-range system and deform of upper crust. The research could provide constrains on processes of upper mantle and deep Earth.
