Use the data provided to graph the Earthquakes and Volcanoes on the map.
Earthquakes Volcanoes
Longitude /Latitude Longitude/Latitude
120 W/35 N 150 W/55 N
105 W/15 N 100 W/ 2 N
80 W/ 5 S 90 W/40 S
65 W/25 S 65 W/20 S
150 W/58 S 150 W/60 S
62 E/28 N 135 E/38 N
44 E/15 N 148 E/42 N
80 W/40 N 165 E/40 S
125 E/ 2 S 75 W/15 N
148 E/10 S 150 E/ 7 S
Procedure 1. On the map, label latitude and longitude lines with North, South, East, or West.
2. Use the information in the data table to mark the location of each earthquake on the world map. Use a blue , 9 pt, circle.
3. Chage the point size to 3 pt. Click the line button, leaving the color the same (blue). Now connect the earthquakes to show a pattern. (Only connect those that appear to show a pattern.)
4. Use the information in the data table to mark the location of each volcano on the world map. Use an orange, 9 pt, circle.
Chage the point size to 3 pt. Click the line button, leaving the color the same (orange). Now connect the volcanoes to show a pattern. (Only connect those that appear to show a pattern.)
5. Place a key at the bottom of your map to show the colors used to indicate earthquakes and volcanoes.

When an oceanic crust meets a continental crust, what occurs?
A The oceanic crust moves under the continental crust, resulting in volcanoes.
B The oceanic crust moves over the continental crust, resulting in volcanoes.
C The two crusts converge, forming folded mountains, such as the Himalayas.
D The two plates separate, forming a submarine mountain range.
