13 What is the lithosphere 1

14 What type of fault usually occurs because of tension? ______________________ 1 1 2

15 What is normal 2

16 What type of fault usually occurs because of compression? ______________________ 3

17 What is reverse ? 3

23 What is Pangaea ? 1

24 Where does sea-floor spreading take place? ______________________ 2

25 What are the mid-ocean ridges 2

26 The mantle is denser than the crust because it contains more______________________ 3

27 What is magnesium 3

28 Seismic waves travel through Earth’s layers at different speeds depending on the______________________ 4

29 What is density 4

30 The fact that similar fossils are found on both sides of the ocean is evidence of______________________ 5

31 What is continental drift. 5

32 What do scientists use the global positioning system for? ______________________ 1

33 What is to measure tectonic plate motion 1

34 What is it called when Earth’s magnetic poles change places? ______________________ 2

35 What is Magnetic reversal 2

36 The layer of rock that comprises 67% of Earth’s mass ____________________. 3

37 What is the mantle ? 3

38 What is the major evidence that sea- floor spreading creates new lithosphere? Explain your answer. 4

39 What is -Molten rock at mid-ocean ridges has magnetized minerals that align with Earth’s magnetic field -When the Earth’s magnetic field reverses, the magnetized minerals align in the opposite direction -The record of magnetic reversals is carried away from each side of the spreading center of a mid-ocean ridge, showing that the molten rock is creating new lithosphere. 4

40 What is the order of the layers of the Earth from the surface to the center? ______________________ 5

41 What are Lithosphere, Asthenosphere, Mesosphere, Outer core, Inner core 5

42 Tectonic plates “float” on what ? ______________________ 1

43 What is Gondwana 1

44 The San Andreas Fault is an example of a ______________________ 2

45 What is a strike-slip fault. 2

46 Earth’s liquid layer ____________________. 3

47 What is outer core 3

48 Stress that stretches a rock layer____________________. 4

49 What is tension 4

50 Explain the process of subduction. 5

51 -oceanic plate is forced beneath a less dense oceanic or continental plate at a convergent boundary -Gravity pulls the oceanic plate into the hot asthenosphere, which causes melting. 5
