Types of Plate Boundaries • Scientists identify the boundaries between two plates by the plate movement. • There are three types of plate boundaries: • Divergent • Convergent • Transform
Divergent Boundaries A divergent boundary is a boundary where two plates are moving away from each other.
Divergent Boundaries This is an example of a divergent boundary. Bridge across theAlfagaria Rift Valley in southwest Iceland, that is part of the boundary between the Eurasian and North American continental tectonic plates.
Divergent Boundaries A Rift Valley is a deep valley located on divergent boundaries. Remember the mid-ocean ridge? The middle part of the mid-ocean ridge is called a rift valley. Rift = crack
Divergent Boundaries As divergent boundaries widen rift valleys form and create new crust from magma that makes its way to the surface.
Convergent Boundaries A Convergent Boundary is a boundary between two plates that are moving toward each other.
Convergent Boundaries One important feature is a deep-sea trench. These form along the subduction zone. Subduction Boundary – When an oceanic plate plunges beneath another plate it is said to be sub-ducting beneath the overriding plate. This boundary between the two plates is a subduction boundary. These boundaries can occur between two ocean plates or and ocean and continental plate.
Convergent Boundaries Collision Boundary – The boundary that forms when two continents collide is called a collision boundary. Mountain ranges are usually formed along such boundaries.
The Himalayan Mountains are an example of a collision boundary.
Transform Boundary A Transform Boundary is a boundary between two plates that are sliding past each other.
Transform Boundaries The San Andreas Fault in North America is an example of a Transform Boundary. Movement along transform boundaries is not uniform and can sometimes cause earthquakes.
