一、解答技巧在地质循环中,地壳物质在内、外力作用下不断运动和变化,从岩浆到形成各种岩石,又到新岩浆的产生,周而复始,构成了地壳物质循环的过程。要使岩石实现转化,必须具备三个条件:一是能量来源,地球内部的热能和外部的太阳能是岩石转化的动力;二是物质运动,地质循环和外力的搬运是岩石转化的链条;三是地质作用,外力作用、变质作用、岩浆上升冷凝、高温熔化是岩石转化的基本条件。
First, the solution skills In the geological cycle, the crustal material, continuous movement and changes under the external force, from the magma to the formation of various rocks, but also to the emergence of new magma, cycle again and again, constitute the cycle of crustal material. There are three conditions that must be met for a rock to be transformed: one is the energy source, the thermal energy inside the Earth and the external solar energy are the motivation for rock transformation; the other is the material transformation, the geological circulation and the handling of external forces are the chains of rock transformation; Geological effects, external forces, metamorphism, magma up condensation, high temperature melting is the basic conditions for rock conversion.
