Question

The following choices contain densites of various materials. Based on this data, which will yield the fastest seismic velocity? O 3.0 g/cm 5.6 g/am 3.3 g/cm 27 g/am QUESTION 14 A convergent boundary is usually associated with which physical features? O Volcanic arcs O Rift valleys Submarine trenches O Horizontally displaced rocks O Volcanic arcs and submarine trenches QUESTION 15 Which of the following scenarios would best indicate that a thrust fault is present at a location? O The crust has lengthened, aloing a graben to slip down and create a pull-apart basin. O Cambrian-aged rocks have been shoved on top of Jurassic-aged rocks. O The hanging wall of the fault has slipped down. O Two parts of the same rock have been horizontally displaced by 20 feet. QUESTION 16 Lava solidifying during a period of reverse polarity will align the magnetic fields of its iron particles toward the O South O East O North O West

Explanation / Answer

1. 5.6 g/cm3 . The higher the density the faster the seismic velocity.

14 Volcanic arcs. volcanic arcs result from the subduction of an oceanic tectonic plate under another tectonic plate.

15. Cambrian-aged rocks have been shoved on top of Jurassic-aged rocks. In thrust fault younger rocks are pushed above older rocks

16. South. lava solidifying during a period of reverse polarity will align the magnetic fields of its iron particles toward the South pole
