ANSWER ALL QUESTIONS IN THIS SECTION



QUESTION 1



Divergent Boundary Seismicity - ANSWERS-Earthquakes that occur at mid-ocean
ridges at shallow depths, have two kinds of faults responsible for tremors:

- Strike-slip

- Normal



QUESTION 2



Transform Boundary Seismicity - ANSWERS-Earthquakes that occur along
transform boundaries.



QUESTION 3



Convergent Boundary Seismicity - ANSWERS-Earthquakes can occur at shallow,
intermediate, or deep depths.



Possibly a result from the phase change of olivine to spinel (a denser material).

QUESTION 4



Intraplate Seismicity - ANSWERS-5% of seismic energy. Earthquakes occur along
ancient, pre-existing faults. Earthquakes here are usually shallow-focus.



QUESTION 5



Intensity - ANSWERS-A measure of the degree shaking caused by an earthquake.



QUESTION 6



Modified Mercator Intensity Scale - ANSWERS-Using buildings to describe the
intensity of an earthquake. Does not measure the earthquakes actual severity.



QUESTION 7



Richter Scale (ML) - ANSWERS-Based on the amplitude of the largest seismic
wave recorded on the Seismogram. This is able to account for the decrease in wave
amplitude as distance increases.

QUESTION 8



Liquefaction - ANSWERS-occurs when an earthquake's violent shaking suddenly
turns loose, soft soil into liquid mud.



QUESTION 9



Is able to create sand volcanoes if there is a layer of loose sand beneath the
overlying bed.



QUESTION 10



Material Amplification - ANSWERS-Loose sediments allow for seismic waves to
easily pass through in contrast to hard material that weakens the amplitude.



QUESTION 11



Seiches - ANSWERS-Rhythmic sloshing of water in lakes, reservoirs, or enclosed
basins.
