地质作用是地球表面的塑造师和雕刻师。地球表面高低起伏、千姿百态的面貌,都是地质作用的杰作。所谓地质作用就是作用于地球的自然力使地球的物质组成、内部构造和地表形态发生变化的作用。按其能量来源,地质作用可分为内力作用和外力作用,连接内外力作用的纽带则是岩石圈的物质循环。 Geological role is the earth’s surface modeling division and engraver division. The ups and downs on the surface of the earth, all kinds of faces, are all the masterpiece of geological effects. The so-called geological role is the role of the Earth’s natural forces on the earth’s material composition, internal structure and surface morphology changes. According to their energy sources, the geological effect can be divided into the role of internal forces and external forces, the link connecting the role of internal and external forces is the material cycle of the lithosphere.
