Tectonic Plate Movement
Convergent Boundaries
A __________________________ is a location where two plates are ____________________________________________.
Plate collisions occur _________________________________________________________________.
There are three possible scenarios that can occur at a convergent plate boundary:
1. ___________________________________________
Ocean plate collides with a Continental plate.
2. ___________________________________________
Ocean plate collides with an Ocean plate.
3. ___________________________________________
Continental plate collides with a Continental plate.
Oceanic-Continental Convergence
An ocean and continental plate collide.
The __________________________________ is made of __________________________ materials as thus _____________ over the ocean crust.
The ________________________________________ sinks, or ____________________ under the continental crust and ____________________________
The location where this occurs is called a _________________________________________.
V-shaped
The subducting ocean plate creates a _______________________ as it sinks under the continental plate.
Trench
As the ________________________________________________________________________________________________________________________.
The __________________________________________________________________________________ at a lower temperature than they normally would.
The ___________________________________________________________________________________________, where it continues to melt more rock.
Eventually the magma will _______________________________________________The ______________________________________________________
Volcanic _______________________________________________________________________________ (along the entire length of the subducting plate).
This forms a ___________________________________________.
EXAMPLES: ___________________________________________________________________________________________________
Oceanic-Oceanic Convergence
An ocean and another ocean plate collide.
The ocean plate that is ________________________________________________________________________________________ into the asthenosphere.
Typically the ___________________ the rock on the plate, the ________________________________ it will be.
Once the plate __________________________________________________, giving off water, thus causing even more rock to melt in the mantle and crust.
The ___________________________________________________________________________________________________________________________
As the volcanic mountains grow, they will ____________________________________________________________________________________________
These islands are called ___________________________________.
EXAMPLES: ___________________________________________________________________________________________________
Continental – Continental Convergence
Two continental plates collide with one another.
__________________________ of the continental plates ______________________________ because they are both ____________________________.

as both plates are ______________________________________________________________________________________________________________
EXAMPLES: ___________________________________________________________________________________________________
