Convergent Boundries : Volcanic Activiy?
Yes!
Convergent Boundry Process
Oceanic subducted. -subduction = oceanic crust destroyedContinental crust is forced upward, forming mountains and leading to volcanic activity.
Divergent Boundry Process
Seafloor spreading = oceanic crust created as tectonic plates move apart, magma rises to form new crust.
Divergent Boundry Features
Mid-ocean ridges, rift valleys, earthquakes
Divergent Boundry: Volcanic Activity?
Yes!
Divergent Examples:
Mid- Atlantic Ridge, East African Rift, East Pacific Rise
Transform Boundry Process
Crust is neither created or destroyed, but broken
Transform Boundry Features
Earthquakes (only!)
Transform Boundry Examples
San Andreas Fault, Alpine Fault (New Zealand), A long the Mid- Atlanic Ridge
