Boundary

Foldable

Transform Boundary

• Two plates build up pressure and friction then slide past each other causing a fault.

• The shearing often causes earthquakes, but neither plate is destroyed in the sideways motion.

• Example: Pacific and North American Plates = California’s San Andreas Fault.


• New crust forms at rift valleys, where two plates diverge, or pull away from each other.

• This type of boundary is “constructive”, since it builds new materials onto the edges of the plates.

• Example: African and Indo-Australian plates = The Great African Rift Valley.

Divergent BoundaryOceanic/ Oceanic

• New ocean crust forms at rift valleys, where two plates diverge, and builds and forms huge underwater mountains, called mid-ocean ridges.

• For the last 250 million years, the Atlantic ocean has been growing wider as new crust is added to Sea-floor spreading.

• Example: Eurasian and North American Plates= the Mid-Atlantic Ocean Ridge and Iceland.

• When two plates carrying continents run into each other, the collision deforms the leading edge of both plates, creating folded mountains.

• When two continents meet head on, neither is subducted because the continental rocks are relatively the same density.

• Example: Indo-Australian and Eurasian plates = Himalayan Mountains

Convergent Boundarycontinental/ continental

• When two plates collide, destruction of the more dense plate will create a subduction zone, a trench and a volcanic mountain.

• The more dense oceanic plate will bend and slide below the continental plate.

• Example: Nazca and South American Plate the Andes Mountains

Convergent Boundaryoceanic/ continental

• When two oceanic plates collide, destruction of the older plate will create a subduction zone.

• Trenches on the ocean floor are the site where magma rises up to form volcano islands.

• Example: Philippine and Pacific Plate= the island arc of Japan
