| Pangaea is a super continent that existed 65 billion years ago. | |
| Seafloor Spreading | Is the process by which new oceanic lithosphere forms. |
| Plate Tectonics | Is the theory that the Earth lithosphere is dividing into little pieces |
| Convergent Boundaries | When two Tectonic Plates collide |
| Divergent Boundary | |
| When two Tectonic Plates separate apart from each other then cause a Mid-Ocean Ridge. | |
| Transform Boundary | The boundary between Tectonic Plates |
| Convection Currents | Are created as warm air rises and cold air sinks |
| Wegener | |
| Was the one that came up with the Continental Drift | |
| Volcano | |
| Are areas of Earthâs surface through which magma and volcanic gases pass. | |
