This document contains a review of earth science vocabulary terms and concepts for a student named Rabbi Goldberg. It includes 15 vocabulary terms with blank spaces for definitions. It also includes 9 sections reviewing various topics: the crust, evidence of crustal changes, earthquake waves, measuring earthquake strength, tsunamis, and using graphs to solve earthquake-related problems. It provides 6 examples of graph-based problems and their step-by-step solutions. The goal is to help the student learn key earth science concepts and practice using graphs to analyze earthquake data.

4. X. How do we use a graph ?
Example Question # 1
If the P wave hits a location at 7 min 30 seconds where is this location?
Step #1 Locate 7 Minutes 30 Seconds
Step # 2 Take a straight piece of paper and draw a line until you hit the P wave
Step # 3 Using a ruler or your piece of paper draw a straight line down
Step 4 The line hits the distance at 5.2 multiply that by 1000 = 5,200
Answer = 5, 200

5. Example Question #2
An earthquake occurred at 5:00:00 a.m. According to the Earth Science
Reference Tables, at what time would the P-wave reach a seismic station
3,000 kilometers from the epicenter?
STEP #1 - LOCATE 3,OOO Kilometers on the graph
Step #2 Move up until you hit the p wave
Step #3 the move to the left and mark down how many minutes it
took the earthquake to hit the location
In our case it is around 5 minutes and 40 seconds
Step # 4 Add 5:40 minutes to 5 am = 5:05 and 40 Seconds
Example question #3

6. If the difference between the p wave and S wave is 6 minutes 20 seconds, how
far away is the location from the epicenter?
Step # 1 Put a piece of paper and measure 6minutes 45 seconds
Step #2 Drag the marked index card up the P wave line until your marking hits
the s wave and the bottom of your card or paper is on the P wave
Step #3 Draw a straight line down and mark the distance in our example it goes
to 5 x1000 = 5,000 km
Example # 4

7. If it takes the S wave 17 minutes to reach Position x How long would it take the
p-wave to get to position x ?
Step # 1 Locate 17 minutes
Step #2 Using a piece of paper or an index card draw a straight line from the 17
until you hit the S wave
Step # 3 draw a straight line down from the point of the S wave until the distance
number
Step #4 Mark off the number ( remember each box is 200 km)
Our answer is 6,000

8. Where is the Epicenter? NYS Lab
Step 1 Look at the graph above it shops three different seismograms at three
different locations The first set of zigzags with the P is the P wave the second set
and larger is the S wave. Subtract the p wave time from the S wave time.
San Jose New York San Francisco
P wave = 21
S wave began 30:30
30:30
- 21:00
8:30 Minutes
Step #2 Take each time difference and do the same thing you did in example #3
and determine the distance for each location.
San Jose New York San Francisco

9. Step #3 On the bottom of your map below there are measurements
using your protractor measure out the distance .

10. Step #4 Without moving your measurement put the point on the correct location
and make a circle
Step # 5 Do this for each location
Step 6 the place where the circles meet mark with an X (or if there is a large over
gap color it in and them mark it.
You are done the X is your epicenter GOOD JOB!!!!!!!!!!!

11. Example #5
Question: If it takes the S wave 18 minute to get to location Y, How long does it
take the p wave to get to the same location?
Step # 1 Locate 18 minutes
Step #2 Using a piece of paper or an index card draw a straight line from the 18
until you hit the S wave
Step # 3 Then draw using a piece of paper or a card a straight line down from the
point of the S wave until the you HIT THE P WAVE
Step #4 From the point on the P wave draw a straight line to the left until you hit
the time line
Step #4 Mark off the time to the nearest 00:10
Our answer is !0 minutes
