The conditions required to form a metamorphic rock are very specific. Schist is a metamorphic rock that comes in almost infinite variety, but its main characteristic is hinted at in its name: Schist comes from the ancient Greek for "split," through Latin and French. What causes rocks to change? sydney drew a flow chart to illustrate the nitrogen cycle. Student Information Name: Date: Objective To identify metamorphic rocks based on physical properties such as the presence of foliation, composition, crystal size, and parent rock Materials • Metamorphic Rock Identification Website • Metamorphic Rock Images (found in Canvas) • Foliated and Non-Foliated Metamorphic Rock Chart (appended to this worksheet) Purpose (5 … Fill out the Rock Characteristics Chart for each of your rocks. FIGURE 6.1 The characteristics of metamorphic rocks are shown on three different scales. ... Sedimentary, and Metamorphic Rocks. After 5 minutes, ask questions from the flow chart to guide students to the correct rock name and chart the results. This information can be used later in trying to identify your rock. Characteristics of Metamorphic Rocks. Classification of metamorphic rocks is based on mineral assemblage, texture, protolith, and bulk chemical composition of the rock. One of the oldest types of rocks on our planet, metamorphic rocks are mainly formed due to changes in the parameters of temperature and pressure, which act on the parent material. The simplest planar features may be primary bedding (akin to the layering in sedimentary rocks). 20.16 Types of … Each shows features resulting from strong Each shows features resulting from strong deformation and solid-state recrystallization caused by changes in temperature, pressure, or fluid composition. Provide students with some information to classify the rocks as sedimentary, igneous or metamorphic, such as a textbook, website material or verbal explanation. texture. Rocks can be deformed and warped due to plate tectonics, compression ,stress, and shearing forces over long periods of time. Students record rock characteristics in the data table. Which characteristic is one of the three main characteristics used to classify igneous rocks? Which labels best complete the flow chart ... From which sources do metamorphic rocks form? Metamorphic. Then, due to various conditions within the Earth, the existing rock was changed into a new kind of metamorphic rock. Metamorphic rocks are formed under the surface of the earth from the metamorphosis (change) that occurs due to intense heat and pressure (squeezing). It also reveals the parent rocks (either igneous or sedimentary rock). Their study provides us with important data regarding formation of the Earth and the past geological environment. Check all that apply ... - metamorphic rock. This chart depicts metamorphic rock types, their texturture, grain size, and characteristics. Metamorphic rock - Metamorphic rock - Major features: The most obvious features of metamorphic rocks are certain planar features that are often termed s-surfaces. Texture In metamorphic rocks individual minerals may or may not be bounded by crystal faces. Each of these will be discussed in turn, then we will summarize how metamorphic rocks are classified. A metamorphic rock, on the other hand, began as a rock—either a sedimentary, igneous, or even a different sort of metamorphic rock.
