  1. Minerals Test Review

  2. Question 1 • What does inorganic mean? • Something that does not arise from once living things; not from the remains of plants or animals

  3. Question 2 • What type of crystal system does halite have? • Cubic

  4. Question 3 • What is cleavage? • The way a mineral breaks in straight lines; a regular pattern that can be determined

  5. Question 4 • True or False: The faster the magma cools, the larger the mineral crystals will form. • False; smaller crystals would form

  6. Question 5 • What does it mean when we say a mineral always contains certain elements in definite proportions? • It has a definite chemical composition

  7. Question 6 • Why is coal not a mineral? • It is made from the remains of plants and animals

  8. Question 7 • True or false: An ore that is near the surface is removed by strip mining? • True

  9. Question 8 • Most minerals do not split apart evenly, instead they have a characteristic type of what? • Fracture

  10. Question 9 • A narrow channel or slab of a mineral that is different from the surrounding rock is called a what? • Vein

  11. Question 10 • Magma that cools deep within the Earth forms minerals with what type of crystals? • Large

  12. Question 11 • A solid mixture of two or metal is a what? • Alloy

  13. Question 12 • How does halite form? • From the evaporation of a water solution

  14. Question 13 • Earthmoving equipment strips away soil to expose ore in what type of mining? • Strip mining

  15. Question 14 • What is the softest mineral on the Mohs hardness scale? • Talc

  16. Question 15 • Why are metals useful as tools? • Because they can be shaped easily, but they are hard

  17. Question 16 • Why are cement, brick, steel, and glass not considered minerals? • Because they are man made (not naturally occurring)

  18. Question 17 • True or false: The process of prospecting involves mixing an ore with other substances and heating the mixture to a very high temperature. • False; smelting is the process

  19. Question 18 • True or false: Iron is separated from oxygen by cooling iron ore. • F; heating not cooling separates them

  20. Question 19 • What is the repeating pattern of a mineral’s particles called? • A crystal

  21. Question 20 • If you broke a mineral into tiny pieces, each piece would show what? • The same crystal shape

  22. Question 21 • What is the term used to describe how a mineral reflects light from its surface? • Luster

  23. Question 22 • What is the hardest known mineral? • Diamond

  24. Question 23 • When can minerals form on Earth’s surface? • When solutions evaporate

  25. Question 24 • Which type of mine often has a network of tunnels that extend deep into the ground? • Shaft mine

  26. Question 25 • What is the color of a mineral’s powder called? • Streak

  27. Question 26 • What is the term for a mineral that glows under ultraviolet light? • Fluorescence

  28. Question 27 • How do minerals form deep inside Earth’s crust? • By the crystallization of melted materials

  29. Question 28 • What is a rock called that contains a metal or other economically useful mineral? • An ore

  30. Question 29 • What type of mining involves digging a huge hole? • Open pit mining

  31. Question 30 • True or false: A mineral with a hardness of 6 will scratch a mineral with a hardness of more than 6. • False; less than 6

  32. Question 31 • True or false: The mineral quartz, which is found in sand, is used to make glass and electronic equipment. • True

  33. Question 32 • What is a gemstone? • A rare, hard, colorful mineral with a brilliant or glassy luster

  34. Question 33 • What is a solid? • A substance with a definite shape and definite volume

  35. Question 34 • What does it mean we say that a mineral must be naturally occurring? • It forms by the process that shapes the Earth; it is not man made

  36. Question 35 • What are the six crystal systems? • Cubic • Hexagonal • Tetragonal • Orthorhombic • Monoclinic • Triclinic

  37. Question 36 • How would we test to see if a mineral is chemically reactive? • By dropping an acid like vinegar or hydrochloric acid on it to see if it fizzles

  38. Question 37 • What are the three ways that minerals form? • Crystallization of molten material • Crystallization of hot water solutions • Crystallization by evaporation of solutions

  39. Question 38 • What are some of the special properties of minerals? • Fluorescence • Chemical Reactivity • Electrical Properties • Radioactivity • Double Image

  40. Question 39 • Why is color not the best way to identify a mineral? • Because minerals like quartz can come in a variety of colors, and some minerals are the same color as other minerals.

  41. Question 40 • What is a mineral? • A solid, inorganic, crystalline solid, with a definite chemical make up
