| Pangaea | theory that all of the continents were once joined together |
| Convergent boundary | When 2 tectonic plates collide |
| Divergent Boundary | When 2 tectonic plates move away from each other |
| Transform Boundary | when 2 plates slide past each other |
| Folded mountains | created when 2 conitnental plates crash into each other |
| Volcanic Mountains | created when an oceanic plate crashes into a continental plate |
| Subduction | when the more dense plate slides under the less dens plate |
| Mid ocean ridge | created when 2 ocean plates move away from each other (underwater mountains) |
| Earthquake | caused by transform boundaries sliding past each other |
| convection currents | circular currents where hot matter rises and cool matter sinks |
| Mantle | made of magma, tectonic plates rest on it |
