How Do Scientists
Determine the Boundaries
of the Earth’s Plates
Procedure
A. Following is a list of geographic coordinates of earthquakes. Plot the location of each
earthquake on the map by placing a dot where the longitude and latitude coordinates
intersect.

1. How have earthquakes helped geologists identify major plates on the earth?
2. Why is knowing the location of plate boundaries important?
3. What might occur as a result of the sliding boundaries illustrated in diagram D?
4. Using page 285 in the text book, label each of the major plates.
• African Plate
• Pacific Plate
• Indo-Australian Plate
• North American Plate
• Antarctic Plate
• South American Plate
• Eurasian Plate
5. Draw arrows on the plates labeled in question #4 showing what direction they are moving.
6. Study diagram A. Where might this type of boundary be found?
7. Study diagram B. Where might this type of boundary be found?
8. Study diagram C. Where might this type of boundary be found?
9. Study diagram D. Where might this type of boundary be found?
