7. These are the questions you will answer in each the boxes
 These are the questions you will answer in each the boxes.  Answers are shown on the following slides.
7.  TYPE OF BOUNDARY
8.  Motion at Boundary.  What kinds of plates move?
9.  Motion at Boundary.   What happens to the plates?
10.  Land Feature formed.  What is made here?
11.  Land Feature Formed.  What else is made here?
12.  Actual examples.  Where is this located in          the Real world         What is the name of the example?

8. As you click through these slides, please read them
As you click through these slides, please read them.  Look at the pictures.  Try to understand the pictures and information about a convergent boundary.

9. Type of Boundary: Convergent Boundary ocean – ocean with Subduction
Examples:

10. Draw this diagram of ocean to ocean crust second box down on left (cross-section view)

11. Type of Boundary: 7. Convergent Boundary
Oceanic crust / oceanic crust 

12. Motion at Boundary: Convergent Boundary ocean/ocean with Subduction
8.  The plates move toward each other - Collide
AND 9.  The older more dense ocean crust subducts (sinks) or goes down below the other less dense crust

13. Convergent Boundary with ocean crust and ocean crust
When 1 subducts, This land feature
Forms. TRENCH

14. Convergent Boundary with ocean crust and ocean crust
When 1 plate subducts, the   
Land feature formed is an
Island volcano arc (a curved line
Volcanic islands)

15. Real world Example of Island Arcs and trenchs:
The Aleutian Islands and Japan
Real world Example of trenches:  Marianas Trench, Peru-Chile Trench

16. 13. Type of Boundary: Convergent (ocean crust and continental crust)
These are the questions you will answer in each the boxes.  Answers are shown on the following slides.
13.   Type of Boundary:  Convergent   (ocean crust and continental crust)
14.  Motion at boundary....  What kinds of plates move? 
15.  Motion at boundary...  What happens at the 2 plates?
16.  Land Feature Formed...What is made here?
17.  Land Feature Formed....What else is made here?
18.  Actual Examples... Where are these boundaries in the Real world?
         What is the name of this example?

17. As you click through these slides, please read them
As you click through these slides, please read them.  Look at the pictures.  Try to understand the pictures and information about a convergent boundary.

18. Draw this in the diagram box (3rd box down on left  (cross-section view)

19. 13.   Type of Boundary: 
 Convergent  with subduction (continental and ocean crust)

20. Motion at Boundary: Convergent Boundary ocean/ocean with Subduction
14. The plates move toward each other - Collide
AND 15. The more dense ocean crust subducts (sinks) under the less dense continental crust

21. Convergent boundary with subduction. Ocean crust and continental crust
Convergent boundary with subduction.  Ocean crust and continental crust.  The more dense plate subducts.  What do you see forming? .

22. The land feature formed at the subduction zone is a trench (16).

23. When  the more dense plate subducts and reaches asthenosphere it begins to melt into magma. It will eventually build up  pressure, until it forms a volcanic mountain range (17). .
Plate melts
 into magma

24. 18. Real world Example of volcanic mountain ranges with a trench
Cascade Mountains – Oregon & Washington
Andes Mountain Range, South America
18. Real world Example of volcanic mountain ranges with a trench

25. 16. Land Feature: Volcanic Mountains 17. Land Feature: trench
13. Type of Boundary: Convergent (ocean crust and continental crust)
Motion: collide & Subduction (ocean crust is more dense than continental )
15. Subduction (sinking) & earthquakes
16. Land Feature: Volcanic Mountains
17. Land Feature: trench
18. Actual Examples: Cascade Mountain Range Andes Mountain Range BOTH part of Ring of Fire – around the PACIFIC PLATE

27. END SUBDUCTION

28. Coming together - colliding
19. Type of Boundary?
20. Motion at boundary?
21. Land feature formed?
22. Real world example?

29. Convergent Boundary
continent crust / continent crust convergent = mountain building / uplift. The crust lifts up.
Himalayan Mountains
