1. Do Now:
In the poem, The Road Not Taken, what does Robert Frost mean by the word diverged?
Two Roads diverged in a yellow wood,
And sorry I could not travel both
And be the one traveler, long I stood
And looked down one as far as I could
To where it bent in the undergrowth;

2. Do Now: While watching the following clip, answer the following:
What happens at:
Convergent boundaries:
Divergent boundaries:
Transform boundaries:
What features can you find at:

3. Turn and Talk: If the word was converge, what might the meaning be?
Example: The crowd converged on the movie star”.

4. Learning Objective:
I will be able to identify and explain the 3 types of plate boundaries.

5. Success Criteria: I can use the ESRT to identify plate boundaries.
I can explain the 3 types of plate boundaries.
I can provide real world examples for each plate boundary.

6. When 2 plates meet… On what page of the ESRT can we find this
information?

7. Convergent Boundaries
Two types of Convergent Boundaries:
1. Subduction: more dense plate goes underneath the less dense plate.
Subduction
Subduction

8. Convergent Boundaries: Subduction
Features that occur:
Earthquakes, Volcanoes, Ocean Trench
Remember:
“The Ocean floor is going DOWN!!!!”

9. Example
Mt. St. Helens- Juan de Fuca plate goes under the North American Plate.

10. Convergent Boundaries
2. Collision: 2 plates are the same material. When they hit, they both buckle up.
THIS MAKES MOUNTAINS!
Features: Earthquakes, Folded Mountains

11. Example Mt. Everest, Himalayas
The plates are still colliding and gaining Elevation
What are some forces of nature that keep Everest from getting much higher?

12. Did we get it?
The block diagram below shows the boundary between two tectonic plates.
Which type of plate boundary is shown? (1) divergent (2) convergent (3) transform
(4) complex 

13. Divergent Boundaries
When two plates move apart.

14. Divergent Boundary Features: On continents: In oceans:
Rift Valley, Volcanoes, Earthquakes
In oceans:
Mid-Ocean Ridge, Volcanoes, Earthquakes

15. Examples:
Great Rift Valley, Africa
Mid-Atlantic Ridge, Atlantic Ocean

16. Example: Great Rift Valley, Africa

17. Did we get it?
The block diagram below shows the boundary between two tectonic plates.
Which type of plate boundary is shown? (1) divergent (2) convergent (3) transform
(4) complex 

18. Sliding/Transform Boundary
When two plates slide past each other.
Features: Earthquakes

19. Example:
California- Pacific Plate slides past the North American Plate at the San Andreas Fault.

20. Example: San Andreas Fault Where is it?

21. Did we get it?
The block diagram below shows the boundary between two tectonic plates.
Which type of plate boundary is shown? (1) divergent (2) convergent (3) transform
(4) complex 

22. Summary:
Describe the 3 types of plate boundaries.
