What are the plate boundaries?
|
Transform, Divergent, and Convergent
|
|
|
When two plates slide past each other. Both plates move in opposite directions. Crust is neither created or destroyed.
|
Transform Boundary
|
|
|
Also known as seafloor spreading.
|
Divergent Boundary
|
|
|
Plates are separating from each other as a new land mass forms. Is seen as mid-ocean ridges and rifts.
|
Divergent Boundary
|
|
|
Two continental plates collide and crumble the edges of the plates and form mountains. Crust is destroyed.
|
Convergent Boundary
|
|
|
When an oceanic plate goes underneath a continental plate
|
Subduction
