地质过程最终是地球热演化的结果.板块构造理论之所以能解释板块边缘所有地质现象,正是因为地幔冷却的缘故.例如,大洋板块在洋中脊形成,这些板块的运动和生长以及最终通过俯冲消减进入地幔是使地幔冷却降温的有效机理,从而导致大规模的地幔对流.地幔柱能解释如板内岩浆活动等另 Geological processes are ultimately the result of thermal evolution of the Earth.The theory of plate tectonics can explain all geologic phenomena at the edge of the plate precisely because of the cooling of the mantle, for example, the formation of oceanic plates at mid-ocean ridges, the movement and growth of these plates and their eventual passage Subduction and subduction into the mantle is an effective mechanism to cool and cool the mantle, resulting in large-scale mantle convection, which can be explained by, for example, intraplate magmatism
