3. Rockin’ & Rollin’$100 Q The process in which sediment is laid down is called this?

4. Rockin’ & Rollin’$100 A Deposition

5. Rockin’ & Rollin’$200 Q When magma undergoes crystallization above ground, what type of rock results?

6. Rockin’ & Rollin’$200 A Extrusive igneous rock

7. Rockin’ & Rollin’$300 Q Explain why you would find the oldest fossils at the bottom of a cliff and the youngest fossils at the top of a cliff.

8. Rockin’ & Rollin’$300 A Superpositionlayering of new material due to depostion and sedimentation/cementation

9. Rockin’ & Rollin’$400 Q Feldspar is considered a _____ because it has a characteristic chemical composition and a definite internal structure. • sedimentary rock C. igneous rock B. mineral D. metamorphic rock

10. Rockin’ & Rollin’$400 A B. mineral Minerals have a definite structure and chemical composition!

11. Rockin’ & Rollin’$500 Q Explain how the radioactive decay of isotopes is used to determine the age of rocks.

12. Rockin’ & Rollin’$500 A • Scientists measure the amount of the original radioactive material left undecayedin the rock, or parent isotope, and the amount of the product of the radioactive material’s decay, or daughter isotope. • Using the known decay rate for each type of isotope, scientists compare the proportions of the parent and daughter isotopes to determine the absolute age of the rock.

13. Give me a plate of lithosphere please!$100 Q Draw picture labeling the: • Asthenosphere • Lithosphere • Crust • Inner core • Outer core

14. Give me a plate of lithosphere please!$100 A

15. Give me a plate of lithosphere please!$200 Q Illustrate the plate boundary where a rift is formed. Include arrows depicting plate movement.

16. Give me a plate of lithosphere please!$200 A

17. Give me a plate of lithosphere please!$300 Q Differentiate between continental and oceanic crust.

18. Give me a plate of lithosphere please!$300 A Oceanic:4-7 mi. thick; dense (basalt) *sinks under continental crust Continental:12-25 mi. thick -most thick beneath mountains -less dense (granite) than oceanic crust

19. Give me a plate of lithosphere please!$400 Q Wegener has plenty of evidence to support his theory of continental drift. Why was his theory not widely accepted at that time?

20. Give me a plate of lithosphere please!$400 A He couldn’t explain how or why the continents moved. The technology needed to discover seafloor spreading and convection currents didn’t exist at that time.

21. Give me a plate of lithosphere please!$500 Q How do earthquakes help scientists learn more about Earth’s core composition?

22. Give me a plate of lithosphere please!$500 A P waves: • can travel through core but deflected • change in type of matter S waves: • can’t travel through core (outer/liquid) transverse & can’t travel through liquid

23. Shake, Rattle & Roll $100 Q Scale to measure earthquakes based on their magnitude and energy of the largest seismic wave.

24. Shake, Rattle & Roll $100 A Richter scale

25. Shake, Rattle & Roll $200 Q Arrange the 3 types of waves in order from slowest to fastest AND from least destructive to most destructive ANSWER BOTH FOR CREDIT

26. Shake, Rattle & Roll $200 A SlowFast Surface, S, P LeastMost destructive P, S, Surface

27. Shake, Rattle & Roll $300 Q Roughly, what time did the S-wave arrive at this seismic station?

28. Shake, Rattle & Roll $300 A ~38-40 minute mark

29. Shake, Rattle & Roll $400 Q How do the Richter scale and Modified Mercalliscale differ?

30. Shake, Rattle & Roll $400 A The Intensity Scale differs from the Richter Magnitude Scale in that the effects of any one earthquake vary greatly from place to place, so there may be many Intensity values (e.g.: IV, VII) measured for the same earthquake. Each earthquake, on the other hand, should have only one magnitude, although the various methods of calculating it may give slightly different values (e.g.: 4.5, 4.6).

31. Shake, Rattle & Roll $500 Q How can we calculate the epicenter of an earthquake? Be sure to be specific with steps/process

32. Shake, Rattle & Roll $500 A • Difference between P and S waves from seismogram • Plot on Travel-Time Curve graph • Locate epicentral distance (radius) • Use 3 seismic stations intersection=epicenter

33. VivaciousVolcanoes $100 Q Volcanism is fueled by this?

34. VivaciousVolcanoes $100 A Magma rising to the surface hot & less dense!

35. VivaciousVolcanoes $200 Q Why are so many volcanoes situated around the Ring of Fire?

36. VivaciousVolcanoes $200 A • Outlines the Pacific plate • Convergent subduction zones!

37. VivaciousVolcanoes $300 Q What component of the 79 AD Mt Vesuivius eruption caused the most casualities? (i.e. how did most people die?)

38. VivaciousVolcanoes $300 A Thermal energy bones cracked, etc and then later on covered by ash and material from eruption

39. VivaciousVolcanoes $400 Q Which type of volcano is the largest and has quiet eruptions? • SHIELD • CINDER CONE • COMPOSITE

40. VivaciousVolcanoes $400 A Shield

41. VivaciousVolcanoes $500 Q • How were/are the Hawaiian islands formed? • Why is there a bend in the island chain? MUST ANSWER BOTH FOR FULL CREDIT

42. VivaciousVolcanoes $500 A • HOT SPOTS • CHANGE IN PLATE DIRECTION
