| Alfred Wegener | German scientist that purposed the idea of continental drift. |
| Paleo-Climate | This is evidence of ancient swamps and glaciers that Wegener used to prove continental drift |
| Rocks and Mountains | Wegener used bands of these solid objects that seamed to connect between continents as proof of continental drift |
| Fossils | Wegener used these remains of the same animals found on distance continents to prove contiental drift |
| Continental Fit | Wegener used evidence like the coast lines appearing to match as evidence of continental drift |
| Convergent Boundary | This type of plate boundary involves plates coming together. |
| Divergent Boundary | This is the type plate boundary involes moving plates apart or splitting a single plate. |
| Transform Boundary | This type of plate boundary involves plates sliding past one another |
| Trench | This is a deep spot in the ocean that is associated with an oceanic plate subducting. |
| Subduction | The process of one plate sliding below another |
| OOC | Oceanic/Oceanic Convergent Boundary. |
| OCC | Oceanic/Continental Convergent Boundary |
| CCC | Continental/Continetal Convergent Boundary |
| OOD | Oceanic/Oceanic Divergent Boundary |
| CCD | Continental/Continental Divergent Boundary |
| Volcanic Arc | A chain of volcanoes that are created at a OCC as the subducting oceanic plate melts |
| Volcanic Island Arc | A chain of volcanoes that are created at a OOC as the subducting oceanic plate melts |
| Folded Mountains | A chain of mountains that are created as 2 continental plates converge |
| Rift Valley | This is at the center of a divergent plate boundary. It is the place where the magma rises |
| Mid-Ocean Ridge | The name for the chain of mountains located near the center of a divergent boundary |
| Oceanic | This is the more dense form of earth's crust |
| Continental | This is the less dense form of earth's crust |
| Continental Drift | This is then name for the theory that the earth's plates move. |
| Melting Crust | This is the result of the process of subduction |
| Magnetite | This is the magnetic mineral found in some magmas that is used like a paleo-compass. |
| Paleo | Ancient |
| Basalt | This dense, black, rock makes up the oceanic crust |
| Granite | This less dense, pinkish, rock makes up the continental crust |
| Convection | This is the process that is happening to release heat from the mantle. It also drives plate tectonics. |
| Sea-Floor Spreading | This is the missing "how" that Wegener needed to prove that continental drift was actually happening |
| Earthquakes | All of the plate boundaries will cause this seismic event |
| 1.1 BYA | CCD - Mid-Continental Rift |
| 1.8 BYA | OCC & CCC - Penokean Mountains |
| 2.7 BYA | CCC - Algoman Mountains |
| 2.4 BYA | CCD - Great Lakes Tectonic Zone |
| 3.5 BYA | OOC - Micro-Continental Collisions |
| Paleo-Magnetism | The work done about this with ancient lava flows and magnetic direction helped prove that sea-floor spreading was occuring |
