6 Plate Boundaries

Sunday, February 2, 2020




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 continental plate collide into one another

Result:Mountain Ranges


Example: Himalyan 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
