1 PLATE TECTONICS REVIEW GAME!!!!

2 Name the four layers of the earth

3 - crust - mantle - outer core - inner core

4 Which part of Earth s structure contains tectonic plates?

5 LITHOSPHERE

6 Name one reason why the theory of continental drift was largely rejected by the scientific community in the early 20th century

7 Many possible answers: - no evidence or proof - Wegener was not a geologist - land masses were unknown - was a stretch from existing ideas

8 At which distance from the continent is a deep trench located? Distance from Continent Ocean Depth 100 km 950 m 200 km 460 m 300 km 1000 m 400 km 5060 m

9 400 meters

10 The magma convection currents within the Earth are due primarily to the fact that fluids will rise if the surrounding fluid is a greater...

11 DENSITY

12 According to the plate tectonics theory, what are the plates sliding on?

13 The Asthenosphere

14 If the crust at the Mid-Atlantic Ridge is being produced at a regular and steady rate, name two letters below when the dating of the rocks would be the same age.

15 Position B and Position E

16 The presence of a folded mountain range is evidence of which process of mountain formation? HINT: what are the plates doing

17 Collision of two plates with one another

18 How many millions of years ago did Pangaea begin to break apart?

19 200 million years ago

20 Which one of the following would be an example of a convergent boundary?

21 Picture A is a Convergent Boundary.

22 Which of the following is something that DOES NOT produce mountains? Folding Volcanic Eruptions Weathering Faulting

23 WEATHERING

24 Volcanic island arcs are associated with this kind of boundary? Between these two kinds of plates?

25 - Convergent Boundary - between 2 oceanic plates

26 What type of geological feature occurs at a boundary when the two plates are moving away from each other?

27 Mid-Ocean Ridge

28 What is the theory that Earth s crust is broken up into large pieces that move and interact?

29 PLATE TECTONICS ( YOU BETTER KNOW THAT!!)

30 What physical property of lithospheric plates allow them to move constantly?

31 Density differences plates either float or sink

32 What natural hazard usually results when two plates scrape and slide past one another?

33 Earthquakes

34 If crustal block A, to the left of the fault in the diagram below, suddenly shifted downward several feet, what would most likely occur at Location C?

35 An earthquake would occur

36 What does sea-floor spreading do relating to plate tectonics?

37 Creates new ocean floor and pushes older lithoshperic plates away

38 How is oceanic crust forced back into the Earth's mantle?

39 It wants to sink because it is made up of a very dense material. **Dense things sink!

40 What is it called when rock is liquefied by thermal energy and pressure beneath Earth s surface?

41 MAGMA

42 Why do volcanoes sometimes form in the middle of a plate?

43 Hot spots

44 How are silly putty, glaciers, and the Earth's asthenosphere all alike?

45 All 3 are solids but act like liquids.

46 Where do earthquakes originate at a point beneath the Earth s surface?

47 FOCUS

48 What is true about the movement of lithospheric plates?

49 they are always moving

50 Name all the types of plate boundaries.

51 Convergent Divergent and Transform Fault

52 Where do volcanoes occur?

53 CONVERGENT AND DIVERGENT BOUNDARIES

54 What causes geologic events such as earthquakes, volcanic eruptions, and the creation of mountains?

55 plate movement

56 Who is the "Father" of the Theory of Continental Drift?

57 Alfred Wegener

58 What type of activity happens at the San Andreas Fault?

59 EARTHQUAKES

60 What do the "plates" of plate tectonics refer to?

61 The segments the Earth's lithosphere is broken up into.

62 How would you describe the ocean floor? What features?

63 How would you describe the ocean floor?

64 Having mountains, plains, plateaus, and valleys

65 Explain a Transform Fault Boundary

66 two plates slide past each other and create Earthquakes

67 Mid-Ocean Ridge is an example of what type of boundary?

68 Divergent Plate Boundary

69 How do the mantle's convection currents move the Earth's plates?

70 Heat currents within the mantle cause the plates to move on the asthenophere based on their density differences.
