The epicenter of an earthquake is located near Massena, New York. According to the Reference Tables, the greatest difference in arrival times of the P and S waves for this earthquake would be recorded in
Albany, NY
Utica, NY
Plattsburgh, NY
Binghamton, NY
Base your answer on the ESRT the table and your knowledge of Earth Science. The table shows some of the data collected at two seismic stations, A and B. Some data have been omitted. Which seismogram most accurately represents the arrival of the P and S waves at station A ?

1,400 km
1,900 km
3,000 km
4,000 km
Base your answer on the ESRT the table and your knowledge of Earth Science. The table shows some of the data collected at two seismic stations, A and B. Some data have been omitted. Which statement best describes the seismic waves received at station B ?
The P-wave arrived at 6:12 pm
The S-wave arrived before the P-wave
The P-wave had the greater velocity
The S-wave passed through a fluid before reaching station B
Base your answer on the ESRT the table and your knowledge of Earth Science. The table shows some of the data collected at two seismic stations, A and B. Some data have been omitted. What is the minimum number of additional stations from which scientists must collect data in order to locate the epicenter of this earthquake?
1
2
3

Base your answer on the diagram of the Earth showing the observed pattern of waves recorded after an earthquake. The lack of S-waves in Zone 3 can best be explained by the presence within the Earth of
density changes
mantle convection cells
a liquid outer core
a solid inner core
Base your answer on the diagram of the Earth showing the observed pattern of waves recorded after an earthquake. The location of the epicenter of the earthquake that produced the observed wave pattern most likely is in the
crust in Zone 1
mantle in Zone 2
crust in Zone 3
core of the Earth
The circles n the map show the distances from three seismic stations, X, Y, and Z to the epicenter of an earthquake. Which location is closest to the earthquake epicenter?
A
B
C
D
Base your answer on your knowledge of Earth Science, the Reference Tables and the map which shows three circles used to locate an earthquake epicenter. Five lettered locations, A, B, C, D and E are shown as reference points. Epicenter distances from three locations are represented by r1, r2 and r3. Location D is about 3,600 kilometers from the epicenter. What was the S-wave travel time to location D ?
5 minutes 10 seconds
6 minutes 20 seconds
7 minutes 30 seconds
11 minutes 40 seconds

The cross-sectional diagram of the Earth shows the paths of seismic waves from an earthquake. Letter X represents the location of a seismic station. Which statement best explains why station X received only P-waves?
S-wave traveled too slowly for seismographs to detect them
Station X is too far from the focus for S-waves to reach
A liquid zone within the Earth stops S-waves
P-waves and S-waves are refracted by the Earth's core.
