Convergent plates boundaries (ocean to continent) : Is when an oceanic plate and a continental plate collide. the oceanic plate is less dense then the continental plate so the oceanic plate slides under it. magma then rises and forms volcanoes, this process is known as subduction.
this a real world event caused by convergent plate boundaries, this is MT. ST. Helens. The Type of tension is compression.
Convergent plate boundaries (continent to continent) : is when two continental plates collide because both plates are equally dense neither plate will subduct, instead both plates uplift and deform. This creates huge mountains.
This is the himalayas, it was created by continent to continent convergent plate boundaries. The type of stress is compression.
Divergent plate boundaries : is when two plates separate magma rises and creates new crust is created. this process can also occur in the middle of continents, and is referred as continental rifting.
Heres a real world example of divergent plate boundaries this is the mid ocean ridge. the type of stress is tension.
Transform Plate Boundaries: are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.
here is a real world example this is the san andreas fault
