| a boundary where 2 plates collide | destructive |
| a boundary where 2 plates pull apart | constructive |
| a boundary where plates appear to slide past eachother | conservative |
| the process where an oceanic plate is taken back into the mantle | subduction |
| a cleft or dip in the ocean floor where 2 plates collide | ocean trench |
| the force generated when plates slide past eachother | friction |
| the process that creates mountain ranges at a destructive margin | folding |
| the type of plate boundary found all around the Pacific ocean | Destructive |
