| Question | Answer |
|---|---|
| Continental drift | The continental drift is the hypothesis that the earth was once one entire continent |
| Pangea | Pangea is a super continent |
| Sea floor spreading | The sea floor spreading is the process by which new oceanic lithosphere forms as magma rises toward the surface and solidified |
| Plate tectonics | Plate tectonics are the theory of plate movement |
| Convergent boundary | Convergent boundary when the boundary when two tectonic plates collide |
| Divergent boundary | The divergent boundary when two tectonic plates separate |
| Transform boundary | The transform boundary when two tectonic plates slide across each other |
| Convection current | The convection current is the changing in density in circular motions that move the tectonic plates |
| Wagner | Wagner was the man who made the theroy that once all continents were connected |
| Volcano | A volcano is a area of earths surface through which magma and volcanic gasses pass |
| Hot spots | A hot spot is a volcanically active area of earths surface far from a tectonic plate boundary |
| Mid ocean ridges | Mid ocean ridges are a long undersea mountain chain that forms along the ocean floor |
| Subduction | Subduction is when two ocean plates collide and one folds over the other |
| Vent | A vent is an opening at the surface of the earth where volcanic material passes through |
