There are 4 main types of plate boundary including: convergent, divergent, subduction and transform-the type of boundary influences the features and events which occur.These pages are a good introduction: http://www.bbc.co.uk/schools/gcsebitesize/geography/natural_hazards/tectonic_plates_rev1.shtml.here are 4 main types of plate boundary including: convergent, divergent, subduction and transform-the type of boundary influences the features and events which occur.
Where the plates meet, their relative motion determines the type of boundary: convergent, divergent, or transform. Earthquakes, volcanic activity, mountain-building, and oceanic trench formation occur along these plate boundaries.The lateral relative movement of the plates typically ranges from zero to 100 mm annually. Convergent boundaries (Destructive) (or active margins) occur where two plates slide toward each other to form either a subduction zone (one plate moving underneath the other) or a continental collision.
