In this activity you will locate where some of the major volcanic and earthquake activities have occurred. You will examine if there is a relationship between the location of these volcanoes and earthquakes and the crustal plates. You will also see if there is a relationship between volcanic and earthquake activity and the major mountain ranges of the world.

MATERIALS: map of the world, data sheet, colored pencils, map of the crustal plates.

PROCEDURE:

1. On the map of the world, draw in the crustal plates; include arrows showing the directions the plates are moving. Use your text or the overhead for your reference.

2. Using the data sheet, find the location of the volcanoes. Locate volcano A. With a colored pencil, mark a on the map at that location. Remember that longitude marked is across the top and Latitude is marked along the side of the map. Continue this until you have located all 17 volcanoes marked their location on the map.

3. Using the data sheet, find the locations of the major earthquakes. Locate earthquake 1. With a different colored pencil, mark a 1 on the map at that location. Continue this until all of the earthquakes have been located and marked on the map.

   Go on-line to the IRIS 'SPYDER' to find a map of the recent earthquakes around the world. Go to Current Seismic Events (text) for the data you need for this lesson. Use a different colored pencil to mark in these earthquakes on your map.

4. Using the data sheet, find the major mountain ranges of the world. Locate their ranges and with another colored pencil mark each of their locations on your map. Use upside down Vs to mark the mountain ranges.

5. Answer the following questions:
   A. Which ocean has a ring of volcanoes around it?

   B. Where are most of the volcanoes located in relationship to the crustal plates?

   C. Which volcanoes are not located on the edge of a crustal plate? What might account for the location of these volcanoes?

   D. Where are most of the major earthquakes in relationship to the crustal plates? Does the recent earthquake data obtained from the Internet follow the same pattern? Why or why not?

   E. What is the relationship between the location of the major volcanoes with the location of the major earthquakes?

   F. Are most mountain ranges located in an area of major earthquake and or volcanic areas?

   G. Are there any major earthquakes not located on the edge of crustal plates? Can you explain the location of these earthquakes?

   H. Are all the mountain ranges listed found along the edge of crustal plates? Explain the locations of these mountains.
