PPT-Mineral Properties Key Concepts

A pure substance such as a mineral can be identified from observations and tests performed to determine its physical properties These properties are based on the unique structure of the substance.

Color Streak Luster Hardness Heft. Cleavage. - mineral breaks evenly along a smooth, flat surface the cleavage plane. Cleavage. Minerals can have 1, 2, 3, 4 or 6 cleavage directions.. UNIT -4. They assist in the identification of minerals – . study their optical properties under the microscope. . . Minerals . are inorganic chemical compounds having a certain lattice shape, size and symmetry, being a result of the geometrical arrangement of the constituents (chemical elements such as Si, Al, O, . A . mineral. is a substance with these characteristics:. Solid. Naturally. Occurring. Inorganic. (never lived, although graphite, diamond, and calcite may be byproducts of organisms). Definite . Chemical Composition. naturally occurring, . inorganic solid . with a specific chemical composition . a definite crystalline structure. Minerals can form from the cooling of magma which is the molten material found beneath Earth’s surface as magma rises closer to the surface the molten compounds no longer move freely and they begin to interact chemically to form minerals. If you closed your eyes and tasted different foods, you could probably determine what the foods are by noting properties such as saltiness or sweetness. . You can also determine the identity of a mineral by noting different properties.. All rocks are made up of 2 or more of these minerals. . Minerals are not rocks!. Silicon and oxygen are the most abundant elements in the crust and in minerals. Oxygen is the most abundant element in minerals. Standard: S6E5b. Investigate the contribution of minerals to rock composition.. There are five characteristics of a mineral. F. ive characteristics. . of a mineral:. Solid—A mineral is always a solid, with a definite volume and shape.. A pure substance, such as a mineral, can be identified from observations and tests performed to determine its physical properties. These properties are based on the unique structure of the substance.. How do we critically evaluate web media?. The internet is home to billions of websites offering products, information and platforms to share with our fellow humans from all around the world.. As media students we need to be able to unpack these sites, evaluate what they are offering and think critically about what message the creators are trying to send us.. What is a Mineral?. Must be a solid.. Must occur in nature.. Must have a definable chemical composition (. NaCl. ).. Must have a crystalline structure.. Must be inorganic.. Video: . http://www.youtube.com/watch?v=rTXSwnkieZc. What do good scientists do?. GOOD SCIENTISTS…. work together and share their information.. observe carefully.. record their observations.. learn from their observations and continue to test, examine, and discuss..
