Name________________________________Date_______Period______ Investigating the Earth's crustal plates: Studying Earthquakes and Volcanoes. INTRODUCTION: The data below represent worldwide earthquake and volcano locations given by their latitude and longitude. The goal of this investigation is to map the locations of these tectonic events to see what relationships can be deduced. MATERIALS: World map, Colored Pencils (2) PROCEDURES: Using a world map and two different color pencils, plot the location of each earthquake in one color and each volcano in the other color. Be sure to make a key on your map.

Discuss the distribution of earthquakes and volcanoes over the surface of the Earth. Are they scattered at random or are they concentrated in zones? Describe your observations. 2. Discuss the distribution earthquakes and volcanoes located in relation to the continents. Are they near the middle of continents or....? Describe. 3. Using reference books, or maps, draw the major crustal plates of the Earth on your world map. Label the names of the plates neatly. 4. Discuss the distribution of earthquakes and volcanoes in relation to the crustal plates. Are they scattered all over the plates or is there a pattern? Describe. 5. Add arrows to your world map showing the direction of crustal plate movement. 6. Is there a relationship between the type of plate boundary and the distribution of earthquakes? Volcanoes? Both? Neither? Describe and explain. Earthquakes and Volcanoes 73 Earthquakes and Volcanoes 74
