Plate Boundaries and Earthquakes
Note: If you forgot how the latitude and longitude coordinate system works, please
review the information provided in the Latitude and Longitude lab.
For this lab, you will be making scientific observations and interpretations about
earthquakes and plate boundaries, after plotting the locations of earthquakes given
latitude and longitude. I recommend that you print the map and table, plot the locations
on the map, and fill in the table. Then, use the map and table, to answer questions on our
online class site so that you can then get credit for the laboratory exercise.
Using the latitude and longitude coordinates provided, plot the position of each of the
locations provided in the table on the next page. To make it easier to see patterns and
make your observations, use red for plotting shallow earthquakes (from the surface to 70
km depth), blue for intermediate earthquakes (70-300 km depth), and green for deep
earthquakes (more than 300 km depth). If you don’t have colored pencils, you could also
choose to use symbols, such as circles, triangles, and squares for shallow, intermediate,
and deep earthquakes, respectively. In addition, complete the table below.
Look on the map to look for patterns and make interpretations from the data. Answer the
following questions:
Which type of plate boundaries tend to have only shallow earthquakes?
Which type of plate boundary tends to have the deepest earthquakes?
Are earthquakes found randomly across Earth’s surface, or are they more
common around plate boundaries?
Do all earthquakes happen at plate boundaries?
Use the map, the table, and your answers from the above questions in to answer the
questions on our online class site for this lab.
