Understanding Minerals: Composition, Formation, and Properties

This content explores the essential characteristics of minerals, including their classification as inorganic solids with crystal structures and specific chemical compositions. It addresses common misconceptions, such as why coal is not a mineral, and highlights the five requirements for classification. The text delves into methods of mineral formation, how to identify minerals, and the significance of hardness scales and special properties. Additionally, it covers key concepts like the difference between compounds and mixtures, the role of atoms, and the economic importance of minerals like ores and gemstones.

  1. Mineral Jeopardy!

  2. Mineral Jeopardy!

  3. Minerals are always in which state of matter?

  4. Solid.

  5. What does organic mean? Are minerals organic?

  6. Living. Minerals are INORGANIC.

  7. Particles lined up in a repeating pattern form what?

  8. Crystal Structure.

  9. To be classified as a mineral, there are 5 requirements. What are they?

  10. Naturally occurring Inorganic Solid Crystal structure Chemical composition

  11. Explain why Coal could be a mineral AND why it is not.

  12. Coal is NOT a mineral. It is a naturally occurring solid, but comes from plant matter, so it is ORGANIC.

  13. Name 2 major ways minerals form.

  14. 1. By cooling of molten material 2. Evaporationwhen dissolved in solution

  15. What common mineral is found in dried lakes? What is its chemical formula?

  16. Salt. Its chemical formula is Sodium Chloride - NaCl

  17. Molten material is known by two names. What are they and why?

  18. Magma& Lava. Magmais under ground, Lavais above.

  19. Under what conditions do large crystals form? Small crystals?

  20. Large: High temperature, slow cooling. Small: Low temperature, fast cooling.

  21. What is a vein? How does it form?

  22. Channel of minerals that is different from the surrounding rock. • When solution crystallizes below the surface.

  23. There are 7 primary ways to identify a mineral. List 4 of them.

  24. Color Streak Luster Hardness Cleavage/Fracture Crystal Structure Density

  25. The scale that rates the hardness of minerals is called what?

  26. The Mohs hardness scale.

  27. Give three special properties a mineral might have.

  28. Fluorescence Magnetic Reacts to acid Generates electricity Radioactive

  29. What is the softest mineral on the Mohs hardness scale? The hardest?

  30. Talc = 1 Diamond = 10

  31. Describe the differences between Fractureand Cleavage.

  32. Fractureis when something breaks irregularly. Cleavage breaks along flat surfaces.

  33. Minerals valued primarily for their beauty are called what?

  34. Gemstones.

  35. A mineral deposit that contains a metal or is economically useful is called what?

  36. Ore.

  37. TauTona and the coal mines of Pennsylvania are what kind of mine?

  38. Shaft mine.

  39. The gold rush of 1849 brought thousands to the West.What is this search for minerals called?

  40. Prospecting.

  41. Iron is an element. Why is steel different and what is this called?

  42. Steel is an alloy – a solid mixture of two or more metals (iron and carbon).

  43. What is an atom? List the 3 subatomic particles.

  44. An atom is the smallest unit of an element. The subatomic particles are Protons, Electrons, & Neutrons.

  45. What is an element?

  46. Substance composed of a single kind of atom.

  47. What are the differences between a compound and a mixture? Give an example of each.

  48. Compounds are chemically combined whereas mixtures are not. Compound = H2O Mixture = Trail mix

  49. Define DENSITY. What is the formula for density and its units?

  50. Amount of matter in a given space. D = mass divided by volume Units are g/mL
