1.
You are watching: Which one of the following best characterizes the asthenosphere?
| Which of the following finest characterizes exactly how the diameter the Earths core and also the nature of the external core were discovered? | by evaluation of the P-wave and S-wave zero zones |
| by utilizing the ratio of stole meteorites to mantle-like meteorites to deduce the loved one diameters |
| crystalline steel was discovered in lavas erupted from hot spots |
| by the truth that P-wave speeds are greater in the outer core 보다 in the reduced mantle |

2. | What is a p or S tide shadow zone on the opposite side of the planet from one earthquake?the region in i beg your pardon seismic station seismographs execute not obtain P or S tide arrivals | | the region in which p waves are absorbed, yet S waves are enhanced, and seismographs room in error | | the zone in i beg your pardon seismic station seismographs execute not obtain surface tide arrivals | | the zone in which ns or S waves room enhanced, and also seismographs obtain a shadowing effect | |

3. | Match the significant Earth boundary with the proper description: Using the pulldown boxes, match each item on the left to the corresponding item in ~ right. | A. The boundary in between the crust and mantle | B. The boundary in between the inner and outer core | C. Found using the 35-degree-wide P-wave zero zone |
Choice AChoice BChoice Cthe Lehmann Discontinuity | Choice AChoice BChoice C | the Core-Mantle boundary | Choice AChoice BChoice C | the Moho | | | | | | 4. | Which of the following finest explains why over there is a P-wave shadow zone in between 105 and also 140 degrees? P waves space reflected in ~ the boundary between the inner and also outer cores. | | P waves space reflected native the inside coreouter main point boundary. | | P-wave velocities are lower in the mantle 보다 in the crust. | | P waves space refracted cross the mantleouter main point boundary. | | | | 5. | Which of the following facts about seismic waves is provided to analyze that the Earths external core is "liquid"? S-waves carry out not travel v liquids | | P-wave velocities are lower in the mantle 보다 the core | | P-waves perform not travel through solids | | P-waves space reflected native the boundary between the inner core and outer core | | | | 6. | Match the letter ~ above the diagram through the ideal description:For each item below, use the pull-down food selection to select the letter the labels the correct component of the image.Choice AChoice BChoice CChoice Dzone that no directly-received ns waves | Choice AChoice BChoice CChoice D | P-wave shadow zone | Choice AChoice BChoice CChoice D | zone of directly-received P and also S waves | Choice AChoice BChoice CChoice D | S-wave shadow zone | | | | | 7. | Which is used as proof that the inner core is solid? S waves space slower in the inside core than in the outer core. | | S waves perform not pass directly through the core. | | P waves are much faster in the inside core 보다 in the outer core. | | S waves are concentrated at the center of the P-wave shadow zone. | | | | 8. | If an earthquake epicenter is located at the Earths phibìc pole, i m sorry of the complying with is no true? choose all the apply. The seismograms in ~ the south pole would certainly not record any type of S waves. | | The seismograms in ~ the south pole would get S waves. | | The seismograms at the southern pole would get P waves. | | The seismograms at new York City would receive both P and also S waves. | | The seismograms in ~ the south pole would certainly not record any kind of P waves. | | | | 9.
