CONVERGENT (and divergent if you missed it yesterday) Plate Boundaries CONVERGENT (and divergent if you missed it yesterday)

CONVERGENT DAY Converge – Collide.  Moving together.

Edusmart notes – Divergent. (Show Mrs. DeLeon when you’re done) pg What is a divergent boundary? Draw a picture of what that looks like. Where are the majority located? What happens at a Mid-Ocean Ridge? What landforms are created by the movement of divergent plates? Click on Edusmart (desktop) Click on Effects of Plate Tectonics Click on Divergent Plate Boundaries

Edusmart notes – Convergent (Show Mrs. DeLeon when you’re done) pg. 83 What is a convergent boundary? Draw a picture of what that looks like. What types of landforms are created by movement of convergent plates (3)? What are the highest mountain ranges called? What happens when an oceanic plate converges with a continental plate? Where do most volcanoes form? Where do you find a lot of subduction zones? What is the Ring of Fire? Where is it located? Where is the deepest point on the planet?

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?

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

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

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

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

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

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)

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

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?

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

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

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

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? .

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

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

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

16. Land Feature: Volcanic Mountains 17. Land Feature: trench 13. Type of Boundary: Convergent (ocean crust and continental crust) 14. 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
