|---|
| Convergant Boundry | when two plates collide head on |
| Divergant Boundry | example:sea floor spreading, or the mid Atlantic Ridge |
| Transform Boundry | two plates scrape past each other |
| Conntinental Drift | theory proposed by Alfred Wegener that explained why the continents appear to fit together at one time |
| Ocean ridge | the same as a divergent boundry |
| subduction zone | when a plate "dives" under another plate |
| crustal uplift | when two plates collide and the crust is thrust upward |
| convection current | is the driving force behind Plate Tectonics |
