PPT-1 – Rocks & Minerals

2 Soil 3 Landscape Lithosphere Lithosphere The lithosphere is a rigid part of the earth that includes the earths crust and part of the upper mantle Ex Mountains plains volcanoes etc. A homogenous, naturally occurring substance with definable internal structure is called mineral. .. Mode of occurrence of minerals:. (1) In igneous and metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc.. 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. 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?. Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle. TYPES OF ROCKS. ROCKS ARE DIVIDED INTO THREE GROUPS BASED ON HOW THE ROCKS . CHAPTER. 13. Mining for . . . Cell Phones?. Large reserves of the metal tantalum are found in the Democratic Republic of the Congo, in Africa.. Tantalum jumped in value in the 1990s as high-tech devices that need tantalum, such as cell phones, became common.. a. metamorphic rock. . b. sedimentary rock. . c. igneous rock. d. sediment. . #1. Which of the following processes is NOT part of the rock cycle?. a. solidification. . b. chiseling. c. erosion. d. metamorphism. 2 – Soil. 3 – Landscape. Lithosphere. Lithosphere. The lithosphere is a rigid . part of the earth . that includes the earth's crust and part of the upper mantle . Ex. . Mountains, plains, volcanoes, etc.. naturally. existing . chemical compounds.. 2)Minerals can be identified by their . physical properties. .. 3)What are the four characteristics of a mineral?. Naturally occurring. Crystal Structure/Chemical Substance. Activator How do rocks relate to minerals? Rock vs Mineral? Decide if each object shown better represents a rock or a mineral. Hold up the rock side or mineral side of your page. Example: Rock Standards:. S6E5b. Investigate the contribution of minerals to . rock composition.. S6E5c. Classify rocks by their process of formation.. S6E5d. Describe processes that change rocks and the . SCience. Mineral Qualities. What is a mineral?. To be a mineral a substance must have ALL of the following qualities. occur naturally. - . formed by nature, not by man. form from an inorganic process- . excludes synthetic minerals. inorganic. non living processes form them. chemically specific. has a unique proportion of elements. crystalline solid. atoms are arranged in specific 3-D patterns. Definition:. Which of following . is not. one of the three classes of rocks? . . Igneous. Metamorphic. Magma. What two processes change rock into sediments?. Cooling & Hardening. Heat & Pressure. Weathering & Erosion. 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.
