6 Plate Boundaries

Plate boundaries occur where two tectonic plates move either away from one another, away from one another, or beside one another.
Convergent Plate Boundaries occur where tectonic plates move towards one another.
Divergent Plate Boundaries occur where tectonic plates move away from one another.
Transform boundaries occur when the plates move beside each other.

This chart will summarize each of the Plate boundaries.

Convergent Oceanic / Continental Type: Destructive Movement: Oceanic plate subducts underneath the continental plate Result: Earthquakes, Trenches, Volcanoes  Example: Lascar volcano located in the Andes	Convergent Oceanic / Oceanic Type: Destructive Movement: Older Oceanic plate subducts underneath the younger oceanic plate Result: Earthquakes,Trench Island Arc Example: Aleutian Islands	Convergent Continental / Continental Type: Collision Zone Movement: Continental plate and a continental plate collide into one another Result: Mountain Ranges Example: Himalayan Mountains
Divergent Oceanic / Oceanic Type: Constructive Movement: Oceanic plate moves away from another oceanic plate Result:Sea floor spreading,trench,new crust formed Example: Mid-ocean ridge	Divergent Continental / Continental Type: Constructive Movement: Continental plate moves away from another continental plate Result: Rift valley Example: East African Rift Valley	Transform Type: Conservative Plate Boundary Movement: Tectonic plates slide past each other Result: Earthquakes Example: San Andreas Fault

There are several mechanisms that cause the plates to move.
