  1. Opening quiz for unit 2 • Get out you ESRT and a piece of paper • The following questions are from your ESRT. • You’ll have a minute per question…

  2. Question 1 • On page 16 of your ESRT what are the two main types of Luster?

  3. Question 2 • I am a mineral that in nonmetallic, has a hardness of around 3 and my chemical formula is CaCO3.

  4. Question 3 • On page 6 of your ESRT What two types of environments of igneous rocks are there.

  5. Question 4 • Looking at page 7 in your ESRT what is the grainsize of Sandstone?

  6. Answers • what are the two main types of Luster? • Nonmetallic and metallic • nonmetallic, has a hardness of around 3 and my chemical formula is CaCO3 • Calcite • What two types of environments of igneous rocks • Intrusive and extrusive • what is the grain size of Sandstone • 0.2-0.006cm

  7. Rocks & Minerals The Building Blocks of society

  8. MineralsLesson 1 Jewelry, computers, walls, and more

  9. MineralsLesson 1 • What is a mineral? • How are Minerals different from rocks? • How are minerals formed? • How are minerals identified?

  10. What is a mineral? • Object that’s: • formed naturally • Solid • internal arrangement of atoms • inorganic

  11. Minerals • There are 1000’s of minerals out there but only a few dozen common ones.

  12. How are minerals different from rocks? • Atoms form minerals • Minerals form rocks • Organized Internal Arrangement Of atomsIAOA

  13. Crystals StructureTetrahedron

  14. How are minerals formed? • Minerals from solution • Cooling of magma • Heat and Pressure

  15. How are minerals formed? • Precipitation from solution

  16. How are minerals formed? • Evaporation from solution

  17. How are minerals formed? • Cooling of magma

  18. How are Minerals identified? • physical properties: color, hardness, cleavage, fracture, streak, and luster • chemical properties: reaction to acid

  19. Mineral properties • Color • Luster • Texture • Streak • Hardness • Cleavage / Fracture • Density • Other

  20. How are Minerals identified? • Color not a good identifier. • Some minerals have different colors • Different minerals can have the same color

  21. How are Minerals identified? • Luster how the mineral reflects light. • Metallic • Nonmetallic

  22. How are Minerals identified? • streak color of a mineral in its powdered form

  23. Diamond = 10 Talc = 1 How are Minerals identified? • Hardness is based on the internal arrangement of atoms • Strong bonds mean hard minerals

  24. How are Minerals identified? • Cleavage flat, smooth, shiny, surfaces occur along weak atomic bonds • How it breaks (in shapes)

  25. How are Minerals identified? • fracture uneven, rough surfaces • Breaks randomly

  26. How are Minerals identified? • Reaction to acid chemical reaction to acid confirms calcite • Feel Soapy, greasy, etc. • Magnetism magnetic properties • Reacts to Ultraviolet light

  27. Some minerals that glow?

  28. Let’s make some minerals • We will melt down some bismuth into lava. • Then I will cool it down slowly. • Last I will drain away any extra lava
