| Abstract: | Based on the evolution history of Moon and other terrestrial planets, continental development process, plate movement tectonics, and solar nebular condensation petrology model that suggested by writers,a discussion about the action of water in Earth’s evolution history has been carried. We think the H2O of primary Earth existed in phyllosilicate mineral in the upper sphere of primary Earth. During the initial melting, almost all H2O come into the primary atmosphere, so the initial crust was anhydrous. The strong impact event drawed by affect of Moon and Earth each other led to the precipitation occured, and the initial crust was immersed in liquid water and damaged completely. In continental development process most of the water come into deep of Earth through the subductions of ancient slabs. A balance between the amount of water come into Earth’s deep by subductions of plate and that come out from Earth’s deep by various volcanic action had been reached about old Tertiary period. |
