PPT-Metamorphic Rocks

Metamorphism Metamorphic rocks appear to have changed in their structure or chemical composition since their creation or formation Originally sedimentary or igneous Altered by heat pressure or exposure to hot fluids in earths crust. Change is Good. Metamorphic Rocks. Formed from intense heat and pressure!. Sources of Heat. 300-1400 degree Celsius temperatures are needed for Metamorphism.. Sources of heat include:. Magma or lava. UNIT . - . 6. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals. Sedimentary. Igneous. Metamorphic. Sedimentary Rock. Write the term and what you believe it to mean. Sedimentary. Contains sediments. Sediments can include:. mud, sand, pebbles, shells, bones, leaves, stems and other remains of living things. GLY 2010 - Summer 2016 - Lecture 11. 2. Metamorphism. The mineralogical, chemical, and structural adjustment of solid rocks to physical and chemical conditions. 3. Metamorphic Rock. Any rock derived from pre-existing rocks by mineralogical, chemical, and/or structural changes, essentially in the solid state . There are three different types of rocks . Igneous ,metamorphic , . sedimentry. . I will tell you . information about them. . . Info on the rocks . The igneous rock. The igneous rock can be found in different colours. The igneous rock is formed when magma cools and solidifies, it may do this above . Metamorphism. :. . the process that creates metamorphic rocks. .. . All made from the alteration of existing rocks by excessive…. . pRESSURE. . AND/OR . Sedimentary-sandstone. Metamorphic- gneiss. Igneous- diorite. 1. What is a Rock?. Naturally Occurring . (not man made). Solid. Mixture of minerals other organic matter. 2. What makes a rock different from a mineral?. happen because of 1.. heat. . (but not enough to cause melting), . 2. pressure and/or 3.chemical reaction . marble. How do the grain patterns of . granite . (igneous) and . gneiss . (metamorphic) compare?. Color . Texture. Light. Dark. Fine. Coarse . Igneous rocks are classified according to their. . origin. , . texture. , and . mineral composition. .. Origin . D. id it harden inside the earth or on the earth’s surface?. S6E5. . Students will investigate the scientific view of how the earth’s surface is formed.. c. Classify rocks by their process of formation. . . Which of these BEST describes the concept of the rock cycle?. Metamorphism. Causes of Metamorphism. Elevated T & P. Fluids (H2O, CO2, CH4, etc.). Directed Stress. Types of Metamorphism. Regional: occur along convergent plate boundaries.. Contact: occurs along margin of a magma intrusion.. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals. January 2013. 3-1 What are rocks?. Rocks in Earth’s Crust. Petrologists. study rocks & minerals.. Rocks are made of minerals (2000). . Classification of Rocks. Classification is the grouping of things that are alike.. 6. What is Metamorphism. Metamorphism. (from the Greek words for “changing form”) is the process by which rising temperature and changes in other environmental conditions transform rocks and minerals.
