Physical properties of Minerals 6th Period

Main characteristics of minerals Let´s remember some characteristics previously studiedSNIFC (Abbreviation)1. S: solid – definite volume and shape2. N: natural - processes form minerals.3. I: inorganic - Are NOT alive and NEVER were alive4. F: fixed Composition - Are elements or compounds with a unique chemical makeup5. C: crystal - Are made up of particles that are arranged in a pattern that is repeated over and over (called a CRYSTAL) Identifying Minerals What is a mineral? naturally formed definite crystalline structure inorganic solid a-c Can you match the physical properties of a mineral with its definition? Color The same mineral can come in a variety of colors. Luster The way a surface reflects light. Streak The color of mineral in powdered form Cleavage The tendency of some minerals to break along smooth, flat surfaces or unevenly along curved or irregular surfaces. Hardness A mineral's resistance to being scratched. Which of the following is not a mineral? oak tree galena salt gold True or False. You can use only color to identify a mineral. True False If a mineral scratches glass it has a hardness of 3 4 5 6 When using the terms metallic or non-metallic you are describing what property? streak luster hardness transparency If a mineral breaks randomly, such as jagged or shell shaped it has cleavage fracture When you are rubbing a mineral sample against a tile you are finding its streak hardness luster density Fill in the missing words for SNIFC: Use this word bank: crystal, natural, solid, inorganic, fixed composition.They have to be typed exactly as word bank or you will not receive credit!! S- solid: definite volume and shapeN- natural : not made by manI- inorganic: are NOT alive and NEVER were aliveF- fixed composition: are elements or compounds with a unique chemical makeupC- crystal: are made up of particles that are arranged in a pattern that is repeated over and over
