Because of this, the crust is made of the lightest materials (rock- basalts and granites) and the core consists of heavy metals (nickel and iron). The crust is the layer that you live on, and ...This layering is a result of the process of metamorphism. Metamorphism is the changing of rocks by heat and pressure. During this process, rocks change either physically and/or chemically. They change so much that they become an entirely new rock. Figure 4.13: The platy layers in this large outcrop of metamorphic rock show the effects of ...Certain metamorphic rocks, such as marble. Oxidized zones of ore bodies, like copper.
