1 ROCKS AND MINERALS UNIT ONE

2 WARM-UP #1 A mineral is inorganic, which means that it contains

3 ANSWER no materials that were once part of living things.

4 WARM-UP #2 The repeating pattern of a mineral’s particles forms a solid called a(an)

5 ANSWER crystal.

6 VOCABULARY mineral inorganic crystal streak

7 VOCABULARY Mineral A naturally occurring inorganic solid that has a crystal structure and definite chemical composition. Inorganic Not formed from living things or the remains of living things

8 VOCABULARY Crystal A solid in which the atoms are arranged in a pattern that repeats over and over again Streak The color of the minerals powder

9 WARM-UP #3 Although brick, steel, and glass all come from substances found in Earth’s crust, they are not classified as minerals because

10 ANSWER They are not naturally occurring

11 WARM-UP #4 Most minerals do NOT split apart evenly. Instead, they have a characteristic type of

12 ANSWER fracture

13 VOCABULARY luster Mohs hardness scale cleavage, fracture

14 VOCABULARY luster The way a mineral reflects light from its surface Mohs hardness scale A chart, with numbers, that ranks the hardness of the mineral as it relates to other minerals

15 VOCABULARY cleavage The minerals ability to split easily along flat surfaces fracture The way a mineral looks when it breaks apart in an irregular way

16 WARM-UP #5 The softest mineral on the Mohs hardness scale is

17 ANSWER talc

18 WARM-UP #6 Igneous rock that cools very quickly when it forms may have a texture that is

19 ANSWER smooth and shiny with no visible grain

20 VOCABULARY granite basalt grains texture

21 VOCABULARY Granite A usually light colored igneous rock that is found in the continental crust Basalt A dark dense igneous rock with a fine grain that is found in the oceanic crust

22 VOCABULARY grains The particles o f minerals and other rocks that give a rock its texture texture The look and feel of a rocks surface, determined by the size, shape, ad patterns of the rocks grains

23 WARM-UP #7 When all the grains in a rock are large and easy to see, the rock is described as

24 ANSWER coarse grained

25 WARM-UP #8 Rock that forms from the cooling of magma below the surface or lava at the surface is called

26 ANSWER igneous rock

27 VOCABULARY Igneous sedimentary metamorphic

28 VOCABULARY Igneous A type of rock that forms from cooling of molten rock at or below the surface

29 VOCABULARY sedimentary, A type of rock that forms when the particle of other rocks or the remains of plants and animals are pressed and cemented together

30 VOCABULARY Metamorphic A type of rock that forms from an existing rock that is changed by heat, pressure or chemical reaction

31 WARM-UP #9 Where does most metamorphic rock form?

32 ANSWER Deep underground

33 WARM-UP #10 The most abundant intrusive, igneous rock in the continental crust is

34 ANSWER granite

35 WARM-UP #11 The process by which sediment settles out of the water or wind carrying it is

36 ANSWER deposition

37 VOCABULARY Extrusive intrusive

38 VOCABULARY Extrusive Igneous rock that forms from lava at the Earth’s surface

39 VOCABULARY Intrusive Igneous rock that forms When magma hardens beneath Earth’s surface

40 WARM-UP #12 A sedimentary rock made up of rock fragments with rounded edges is called

41 ANSWER conglomerate

42 WARM-UP #13 Chalk formed from sediments made of skeletons of microscopic living things in the ocean must be a(an)

43 ANSWER Organic rock

44 WARM-UP #14 The texture of a metamorphic rock that has grains arranged in parallel layers is described as

45 ANSWER foliated

46 VOCABULARY sediment erosion compaction cementation

47 VOCABULARY Sediment Small solid pieces of material that comes from rocks or organisms Erosion The process by which water, wind, ice or gravity moves weathered rocks or soil

48 VOCABULARY cementation The process by which dissolved minerals crystallize and glue particles of sediment together into one mass compaction The process by which sediments are pressed together by their own weight

49 WARM-UP #15 Erosion on a mountain range that was pushed up as a result of two continental plates colliding will lead to the formation of

50 ANSWER Sedimentary rock

51 WARM-UP #16 During the rock cycle, a collision between two continental plates could force one plate down toward the heat of the mantle, producing

52 ANSWER Metamorphic rock

53 WARM-UP #17 The heat that changes a rock into metamorphic rock comes from

54 ANSWER The heat of the mantle

55 VOCABUALRY Clastic rock Organic rock Chemical rock

56 VOCABUALRY Clastic rock – Sedimentary rocks that are formed when rock fragments are squeezed together under high pressure

57 VOCABUALRY Organic rock- Sedimentary rocks that are formed when the remains of organisms are deposited into thick layers– coal & limestone

58 VOCABUALRY Chemical rock – Sedimentary rocks that are formed when minerals crystal from a solution

59 WARM-UP #18 A series of processes on Earth’s surface and in the crust and mantle that slowly changes rocks from one kind to another is called

60 ANSWER The rock cycle

61 WARM-UP #19 If you broke a mineral into tiny pieces, each piece would

62 ANSWER Still show the same crystal structure

63 VOCABULARY Foliated Rock Cycle

64 VOCABULARY Foliated Terms used to describe metamorphic rocks that have grains arranged in parallel layers or bands Rock cycle A series of processes on the surface and inside Earth that slowly changes rock from one kind into another

65 WARM-UP #20 The process in which dissolved minerals crystallize and glue particles of sediment together is

66 ANSWER cementation

67 WARM-UP #21 A mineral with a hardness of 6 will scratch a mineral with a hardness of ________ than 6.

68 ANSWER less

69 WARM-UP #22 Particles of minerals called ___________ give a rock its texture.

70 ANSWER grains

71 WARM-UP #23 The small particles of rock or the remains of living things that make up sedimentary rocks are called _________________.

72 ANSWER sediment

73 WARM-UP #24 High pressure can change an igneous rock into a(an) _____________________ rock.

74 ANSWER metamorphic

75 WARM-UP #25 Each major group of rocks follows ___________________ in the rock cycle.

76 ANSWER Many pathways
