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
