Base your answer to the question on the map and table below and on your knowledge of Earth science. The map shows the zones of observed effects reported after a 1944 earthquake that occurred near Massena, New York. The isolines on the map are boundaries between zones of observed effects described in the Modified Mercalli Scale table. Four cities are labeled on the map.

a)
b)
c)
d)
5.

1 minute 10 seconds
b)
2 minutes 10 seconds
c)
3 minutes 20 seconds
d)
4 minutes 20 seconds
6.

East Pacific Ridge
b)
Iceland Hot Spot
c)
Aleutian Trench
d)
Peru-Chile Trench
7.
The epicenter of an earthquake was located 1800 kilometers from a seismic recording station. If the S-wave arrived at the seismic station at 10:06:40 a.m., at what time did the P-wave arrive at the same seismic station?
a)
10:03:00 a.m.
b)
10:03:40 a.m.
c)
10:09:40 a.m.

Base your answer to the question on the diagram below and on your knowledge of Earth science. The diagram represents a cut-away view of Earth’s interior and the paths of some of the seismic waves produced by an earthquake that originated below Earth’s surface. Points A, B, and C represent seismic stations on Earth’s surface. Point D represents a location at the boundary between the core and the mantle. Refer to Figure 4 and answer the following Question:
Only P-waves were recorded at seismic station C because P-waves travel
a)
only through Earth’s interior, and S-waves travel only on Earth’s surface
b)
fast enough to penetrate the core, and S-waves travel too slowly
c)
through iron and nickel, while S-waves cannot
d)
through liquids, while S-waves cannot
13.
Refer to Figure 4 and answer the following Question:
Which process prevented P-waves from arriving at seismic station B?
a)
refraction
b)
reflection
c)
convection
d)
conduction
14.
Refer to Figure 4 and answer the following Question:
Seismic station A is 5000 kilometers from the epicenter. What is the difference between the arrival time of the first P-wave and the arrival time of the first S-wave recorded at this station?
a)
2 minutes 20 seconds
b)
6 minutes 40 seconds
c)
8 minutes 20 seconds
d)
15 minutes 00 second
