• Convergent Continent-Ocean• Convergent Ocean-Ocean• Convergent Continent- Continent

Convergent Continent-Ocean Convergent Continent-Ocean Plate BoundaryPlate Boundary

• Occurs when an ocean plate collides with a continental plate

• The ocean plate will ALWAYS go underneath the continental plate

• The process of the ocean plate going underneath a continental plate is called - SUBDUCTION

What forms at a Convergent What forms at a Convergent Continent-Ocean Boundary?Continent-Ocean Boundary?

• New Metamorphic Mountains• Ocean trenches• Subduction zone for plate melting• Magma chamber from melted plate• Continental Volcano above magma

Boundary?Boundary?• Along the subduction zone there will

be:– shallow EQ’s– intermediate EQ’s– deep EQ’s

• All these EQ’s occur along a 45° angle

Convergent Ocean-Ocean Plate Convergent Ocean-Ocean Plate BoundaryBoundary

• Occurs when an ocean plate collides with another ocean plate

• The most dense ocean plate will ALWAYS go underneath the less dense plate

• The process of an ocean plate going underneath another ocean plate is called - SUBDUCTION

• Ocean trenches• Subduction zone for plate melting• Magma chamber from melted plate• Oceanic Volcano above magma

chamber• A series of new islands called an

Archipelago or an Island Arc– an archipelago is a chain of volcanic

islands

• Occurs when a continental plate collides with another continental plate

• The two continents deform because of the collision

• Both plates are bent up and down
