38. Contact #3 is both a A. conformable contact and an unconformity B. fault and an unconformity C. nonconformity and an angular unconformity D. disconformity and a nonconformity at various points 39, Which statement about contact #3 is correct? A. It and contact #2 once formed a continuous unconformity B. It was once elevated farther above contact #2, but faulting has brought them closer together C. It presents an example of an angular unconformity D. It must be younger than the conglomerate, due to the principle of baked contacts 40. Earthquake waves that pass through the interior of Earth are termed A, interior waves C. surface waves B. R-waves D. body waves . 41. Which type of earthquake waves generally travels fastest'? A. interior waves C. surface waves B. R-waves D. body waves 42. Surface waves . A. travel more rapidly than body waves B. cause most of the damage to buildings during earthquakes C. are the first waves initially produced in an earthquake D. are the first waves to arrive at a seismograph station after an earthquake

Explanation / Answer

40. Eathquake waves which travel interior of the Earth are known as Body Waves

41. Body Waves generally travel faster.

42. Surface waves causes most of the damage to the buidings during an earthquake.

43. Body Waves include both P and S waves

44. P wave travels the fastest of all the waves

45. The point within Earth where an earthqukaes takes place is known as hypocenter (focus)

46. The point on Earth's surface directly above the point where an Earthquake occurs is termed as the Epicenter

47. Three seismic stations are necessary to find the epicenter of the earthquake

48. Mericalli Scale asssess the effects of an Earthquake on humans and human made structures.

49. Earthquakes occuer along all three major types of plate boundaries

50. Intermediate and deep earthquakes occur along Convergent plate boundaries only
