12. What type of sedimentary rock is Coal? Organic

13. What type of sedimentary rock is Rock Salt Chemically formed (Evaporate)

14. What type of sedimentary rock is Sandstone? Clastic

15. What type of sedimentary rock is Limestone

16. Define Lithification The process of turning sediments to stone

17. Define Bedding The way in which sediments are deposited in layers

18. Define Graded Bedding The largest sediments are on the bottom and the smallest ones are on top.

19. Define cementation The “gluing” together of sediments through natural means such as calcite build up.

20. Define evaporates Rocks that form as a result of the water that they are in evaporating (ex: salt water leaves behind the salty crust)

21. Which rock is made of particles that are 0.006 to 0.2? Sandstone

22. Which rock is made of particles that are 0.0004 to 0.006? Silt stone

23. Which rock is made of particles that are smaller than 0.0004? Shale

24. Which rock is made of pebbles and cobbles that are rounded
Which rock is made of pebbles and cobbles that are rounded? Conglomerate

25. Which rock is made of pebbles and cobbles that are angular? Breccia

26. Which rock is made of Gypsum? Rock gypsum

27. Which rock is made of Halite? Rock salt

28. Define Foliated When due to pressure a rock exhibits shininess due to mica crystals or wavy bands as a result of realigning crystals

29. Define Contact Metamorphism When a rock is changed due to coming into contact with magma or lava.

30. Define Regional Metamorphism The rock changes due to the pressure from large regions of land smashing into each other.

31. Define Hydrothermal Metamorphism Rocks chemically changing due to an exchange of minerals (some new coming in, some old going out) caused by hot water and a chemical change.

32. What causes metamorphism? Heat and pressure

33. Which rock shows bands? Gneiss

34. What is a Gneiss geology joke
What is a Gneiss geology joke? I might be gneiss but don’t take me for granite!

35. Which metamorphic rock will fizz in acid? Marble

36. Which rock is only fine grained and has regional metamorphism
Which rock is only fine grained and has regional metamorphism? Slate or Anthracite coal

37. Which rock has a platy mica surface? Schist

38. Which rock has a microscopic mica crystals on its surface? Phylite

39. Which rock is a low grade metamorphism of shale? Slate

40. Which rock is the metamorphosed version of bituminous coal
Which rock is the metamorphosed version of bituminous coal? Anthracite coal

41. Which rock is formed from contact or regional metamorphism and is made from limestone or dolostone? Marble

42. Which rock is formed from contact metamorphism and can be made from a variety of rocks? Hornfels

43. Which rock is formed from contact or regional and is made from quartz sand stone? Quartzite

44. Which rock is formed from contact or regional metamorphism is made from conglomerates? Metaconglomerate

45. Why would limestone dissolve in acid rain
Why would limestone dissolve in acid rain? It is made of calcite which dissolves in acid.

46. Why would marble dissolve in acid rain
Why would marble dissolve in acid rain? It is made of limestone which is made of calcite which dissolves in acid.

47. What does the rock cycle show you
What does the rock cycle show you? Over time, any rock can become any other rock.

48. How do igneous rocks form
How do igneous rocks form? The cooling (solidification) of magma or lava

49. How do clastic sedimentary rocks form
How do clastic sedimentary rocks form? The cementation of deposited rock fragments

50. How do chemically formed sedimentary rocks form
How do chemically formed sedimentary rocks form? They are either precipitate out of solution or are left as evaporates when the solution evaporates.

51. How do bioclastic sedimentary rocks form
How do bioclastic sedimentary rocks form? Compacted organic materials such as plants or shell fragments.

52. How do metamorphic rocks form? Heat and/or pressure
