PLATE BOUNDRIES

PLATE BOUNDRIES -

The boundries between the plates are the areas where most tectonic activity takes place . Three types of movement occur at the plate boundaries ,the plate can either moves towards each other ,move apart ,or slide past each other . The effect this has on earth's structure depends on wheather the margin is between two continental plates ,two oceanic plates ,or an oceanic and continental plate.
