Convergent Plate Boundaries Finz 2011

What are the 3 types of Convergent Plate Boundaries? Convergent Continent-Ocean Convergent Ocean-Ocean Convergent Continent- Continent

Convergent Continent-Ocean Plate 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 Continent-Ocean Boundary? New Metamorphic Mountains Ocean trenches Subduction zone for plate melting Magma chamber from melted plate Continental Volcano above magma chamber

What kinds of Earthquakes occur at an Convergent Continental-Ocean 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 Boundary 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

What forms at a Convergent Ocean-Ocean Boundary? 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

What kinds of Earthquakes occur at an Convergent Ocean-Ocean 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 Continent-Continent Plate Boundary 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

What forms at a Convergent Continent-Continent Boundary? New Metamorphic Mountains

What kinds of Earthquakes occur at an Convergent Continent-Continent Boundary? Along the collision zone there will be: –shallow EQ’s –intermediate EQ’s –deep EQ’s

Transform Fault or Side-by-side Plate Boundary Occurs along a crack in a tectonic plate Each plate will slide past one another

What forms at a Transform Fault or Side-by-side Boundary? Fault lines Rift Valleys

What kinds of Earthquakes occur at a Transform Fault or Side-by-side Plate Boundary? Along the friction zone there will be: –shallow EQ’s –intermediate EQ’s –deep EQ’s
