AA BB CC DD EE FF GG 1Foliation is layering in the rock formed when elongate or … A rock is an aggregate of one or more minerals, or a body of undifferentiated mineral... Igneous rocks (from the Latin word for fire) form when hot, molten rock crystallizes and solidifies. Gem Minerals From Metamorphic Rocks. Students should write down observations about how metamorphic rocks are formed, based on what was learned in this activity. It is smoothly rounded on three sides and a sheer vertical face on the fourth. Then we will look at some different examples of metamorphic rock and discuss how their properties make them fit for their uses. When a 'magma' student has been tagged by a 'cold' student, he or she turns into an igneous rock (which is what occurs when magma cools). After the ingredients have been smashed together, students can observe the new metamorphic 'rock.' Finally, the 'melting' student can come out and tag all of the 'metamorphic rocks.' Are there geologic maps or publications for where I live? Process of Metamorphism:The process of metamorphism does not melt the rocks, but instead transforms them into denser, more compact rocks. In this lab, you will study photos of several metamorphic rocks and determine their physical properties. 7.3.1. The two major factors that influence the development of metamorphic rocks are heat and pressure. Metamorphic rock, as its name suggests, is a rock that has changed form. Sedimentary rocks often have distinctive layering or bedding. Describing Metamorphic Rocks Worksheet Students will learn how metamorphic rocks form and get hands-on practice at telling if a metamorphic rock is foliated or non-foliated! 's' : ''}}. The 'heat/pressure' students and the 'melting' student will remain on the sidelines for now. Metamorphic rocks form when rocks are subjected to high heat, high pressure, hot mineral-rich fluids or, more commonly, some combination of these factors. Coal – compacted plant remains Cohena - compacted shells 1.7. The buildings of our Nation's Capital are constructed with rocks from quarries located throughout the United States and many distant lands. Place a few pieces of each ingredient in a cupcake holder, and then place the cupcake holder into a microwave. Interactive Science Activities. Metamorphic Rocks Teaching students about the rock cycle creates a firm basis for geology. Metamorphic Rock Composition Metamorphic rocks contain many of the same minerals found in igneous and sedimentary rocks. Metamorphic rocks started out as some other type of rock, but have been substantially changed from their original igneous, sedimentary, or earlier metamorphic form. Although metamorphic rocks typically form deep in the planet’s crust, they are often exposed on the surface of the Earth. They usually start out as sedimentary rocks like sandstone or shale, but then volcanic material pushes up from below and bakes the sedimentary rock into a metamorphic one. Rock Definition Worksheet – If you just need a quick worksheet to practice the definitions for … That way the activity moves smoothly and the boys aren’t waiting on my to get organized. Uplift and erosion of the crust have combined to expose them on the surface. They form from deposits that accumulate on the Earth's surface. Metamorphic rocks are igneous, sedimentary, or metamorphic rocks that have been changed or altered in response to deep burial, intense heat and pressure without melting the rock or interaction with hot fluids. Sciences, Culinary Arts and Personal Displaying top 8 worksheets found for - Metamorphic Rock Grade 4. Metamorphic rock is very strong and the layers in it can be difficult to distinguish. Because sediment can move, the 'sediment' students can move around. Once all of the 'sediment' students have been changed into 'sedimentary rock,' the 'compacting' students go to the sidelines. This changes them to 'metamorphic rock.' The melt originates deep within the Earth near active plate boundaries or hot spots, then rises toward the surface. It includes a … All other trademarks and copyrights are the property of their respective owners. Metamorphic Rocks - Introduction and Review Activity Note: This item is now part of the "Rock Pack II" see below :Note Introduce students to Metamorphic Rocks and Foliated and Non-Foliated properties. Activity 25: Metamorphic Rock Identification Maine Geological Survey Student Sheet Purpose: In this first part of the activity, you will identify a number of metamorphic rocks that are commonly found in the state of Maine. How can you tell? Outcrop of biotitic meta-sandstone in the lower part of the Gunsight Formation, cut by white quartz veins with alteration envelopes of coarsely crystalline black biotite and minor muscovite. (You can see distinct layers, as well as inclusions like fossils.) Summary sheet is adapted from another user, thank you. Students should note how the rocks are similar. This means that a metamorphic rock is a rock that has changed in some manner by certain processes. Lab 06 - Metamorphic Rock Identification Key 1. slate, phyllite, schist --> shale protolith gneiss -- > granite protolith 2. quartzite --> sandstone protolith hornfels --> shale protolith marbles --> limestone protolith skarn --> dirty limestone protolith 3. igneous rocks = crystallization; metamorphic rocks = recrystallization 4. Here are two activities to help you better understand metamorphic rocks. No matter how much pressure you apply, the grains will not align! In metamorphic rocks, minerals from the original rock form new minerals, like gneiss, quartzite, or marble. The term metamorphic refers to a change in form. - Definition & Explanation, California Geology: Geologic Map & History, Gold Mining Lesson Plan for Elementary School, Crystals Lesson Plan for Elementary School, Processing & Impact of Minerals Lesson Plan, Biological and Biomedical Metamorphic rocks form from sedimentary or igneous rocks that have been changed by heat or pressure underground. Conditions like these are found deep within the Earth or where tectonic plates meet. Igneous and sedimentary rocks both have the potential to become a metamorphic rock. Instruct the 'heat/pressure' students to enter the 'rock cycle area,' and tag the 'sedimentary rock' students. This EarthWord should cover it... For the first time, geologists have extracted intact rock samples from 2 miles beneath the surface of the San Andreas Fault, the infamous rupture that runs 800 miles along the length of California. Mineral: Garnet SchistPrimary Commodity: GarnetPrimary Commodity Uses: Garnet is mostly used for abrasives, water filtration, and some electronics. This series of activities is geared towards metamorphic rocks, which are created when a rock is exposed to high pressures and temperatures. {{courseNav.course.mDynamicIntFields.lessonCount}}, Rock Cycle: Igneous, Sedimentary, and Metamorphic Rocks, Rock Deformation & Mountain Building Activities, Sedimentary Rocks: Definition, Types & Examples, Sedimentary Rocks Lesson Plan for Elementary School, Classification of Igneous Rocks: Textures and Composition, Metamorphism of Rocks: Definition, Process & Influencing Factors, What Are Minerals? These rarely contain fossils. Why would a fossil only be present in a sedimentary rock? The process that involves in creating igneous and metamorphic rocks require a lot of heat and pressure destroying any fossils. Metamorphic rocks are often squished, smeared out, and folded. Rocks, Minerals, and Landforms: 12 StudyJams! After the game is complete, it can be repeated a few times until students get the basic gist. Begin by having students observe the rock samples, and write down some observations in their science notebooks. How Long is the School Day in Homeschool Programs? Introduce students to everything from volcanoes and earthquakes to fossils and sedimentary rocks using these 12 fun StudyJams! This activity allows students to see how metamorphic rocks fit into the rock cycle. Once tagged, the 'igneous rock' students become 'sediment,' so they need to go to the bucket and trade out their signs, and then return to the 'rock cycle area.'
