1. D45 Plate Boundaries

2. D45 Earthquakes & Volcanoes

3. D45 Hawaii Volcanoes

4. D45 Boundary Background
The previous map (p D42) shows locations of earthquakes and volcanoes on Earth.
Many of the most active volcanoes are on the edges of the Pacific Ocean, the “Ring of Fire”.
The theory of plate tectonics helps explain this
CHALLENGE QUESTION: HOW does plate tectonics explain the locations of earthquakes, volcanoes and mountain ranges?

5. D45 Plate Motion Vocabulary
Convergent: plates colliding (mountains)
Divergent: plates dividing (volcanoes)
Transform: plates sliding along (earthquakes)
Subduction: one plate sliding under another

6. D45 Boundary Reading In the textbook begin reading p D43 – D46.
Use separate paper to take 3 good notes for the first paragraph. This may be collected.
Discuss quietly at your table and be prepared to discuss as a class what you discovered.
Continue as directed by your teacher.
Then answer the following questions in your lab book. You will need a ruler.
