2.
Use one color marker to plot the earthquake data on the world map.
3.
Use a different color marker to plot the volcano data on the world map.
4.
MAKE SURE TO ADD A KEY FOR THE COLORS YOU USE AT THE BOTTOM OF YOUR MAP!!!

Data: Analysis:
1.
Observe the pattern of earthquakes and volcanoes over the surface of the Earth. Are they scattered
at random or are they concentrated in certain areas and in certain patterns? Describe your
observations.
2.
Explain our observations – Why do you think that earthquakes and volcanoes occur in these
areas?
3.
Use a pencil to roughly draw lines where the tectonic plates fit.
4.
Observe the pattern of earthquakes and volcanoes in relation to the crustal plates. Are they
scattered all over the plates or is there a pattern? Describe your observations.
5.
What is the volcano in the middle of that Pacific Ocean? Why is it not on a plate boundary?
6.
Write a summary describing what you have learned from this activity.
