Metamorphic rocks are created by the physical or chemical alteration by heat and pressure of an existing igneous or sedimentary material into a denser form.Click to see full answer. Then, what is metamorphic rock and example?Examples of metamorphic rocks include anthracite, quartzite, marble, slate, granulite, gneiss and schist. Anthracite is a type of coal with a high carbon count, few impurities and with a high luster (meaning it looks shiny). Marble is a metamorphic rock that is formed from the sedimentary rock limestone.Subsequently, question is, how are metamorphic rocks formed give two examples? They may be formed simply by being deep beneath the Earth’s surface, subjected to high temperatures and the great pressure of the rock layers above it. Some examples of metamorphic rocks are gneiss, slate, marble, schist, and quartzite. Hereof, what are the characteristics of metamorphic rock? Metamorphic Rocks. Metamorphic rocks were once igneous or sedimentary rocks, but have been changed (metamorphosed) as a result of intense heat and/or pressure within the Earth’s crust. They are crystalline and often have a “squashed” (foliated or banded) texture.How can you identify a metamorphic rock?Metamorphic rocks are rocks that have become changed by intense heat or pressure while forming. One way to tell if a rock sample is metamorphic is to see if the crystals within it are arranged in bands. Examples of metamorphic rocks are marble, schist, gneiss, and slate.
