LAB: Locating Patterns of Earthquake and Volcano Distribution
Problem
What is the path of earthquake and volcano distribution worldwide?
Materials (per student)
Earthquake and volcano locations
World map showing latitude and longitude
2 different colored pencils
Procedure
1. Using the information in the table on earthquakes, plot the location of each
earthquake on the map on the following page. Make a dot on the map for
each earthquake using one of the colored pencils.
2. Using the information in the table on volcanoes, plot the location of each
volcano on the map on the following page. Make a dot on the map for each
volcano using the other colored pencil.
3. If directed by your teacher, also plot the location of recent earthquakes and
volcanoes. Remember to use the same colored pencils as before.
4. Answer the questions on the back of this paper.
