Plate tectonics
| Question | Answer |
|---|---|
| Seismic Wave | earthquake energy traveling in a wave |
| Lithosphere | Earth's crust |
| Asthenosphere | Earth's mantle (2nd layer from top) |
| 3 Properties that increase as you get deeper into Earth (Listed alphabetically) | Density, Pressure, Temperature |
| How do we know about the inside or Earth? | Seismic waves |
| Heat transfer | When heat travels from hot to cold |
| Convection | Heat transfer in a fluid (liquid or gas), moves in circles |
| Theory of Continental Drift | Continents were once together in a super continent, then drifted apart |
| Pangaea | supercontinent |
| Evidence of continental drift (List alphabetically) | Climate Fossils Landforms |
| How is continental drift different from plate tectonics? | HOW the continents moved |
| Plate tectonics | continental drift + Ocean plates |
| Sea floor spreading | The process of magma rising up through the ocean floor, pushing plates apart and creating new sea floor |
| Subduction | The process of more dense ocean floor sinking below less dense continental crust |
| Transform boundary | when 2 plates slip past each other |
| San Andreas | transform boundary in California |
| Volcanic eruptions affect our atmosphere by | blocking the sun, causing rain |
| Convergent Boundary | A plate boundary where two plates move toward each other. |
| Divergent Boundary | A plate boundary where two plates move away from each other. |
| Lystosaurus | Fossil evidence of continental drift |
| Glossopteris | fossil plant that helps support the theory of continental drift |
| Mesosaurus | freshwater reptile whose fossil provided evidence for Pangea |
| oil reserves | oil that has been discovered but remains unused in the ground |
| Coal beds | from North America and Europe support reconstruction into Laurasia |
| earthquake | The shaking that results from the movement of rock beneath Earth's surface. |
| Mid-ocean ridge | An underwater moutain chain where new ocean floor is formed |
| Ocean Trench | Deep valley in the ocean floor that forms along a subduction zone |
| Tsunami | A giant wave usually caused by an earthquake beneath the ocean floor. |
| Magnetic Stripes ocean ridge | magnetic reversals in rock that provide evidence for sea-floor spreading |
| age of rocks at the Mid Ocean Ridge | age increases with distance; provides evidence for sea-floor spreading |
| new volcanic material at ocean ridge | provides evidence for sea floor spreading |
| Evenly distributed | equal amounts spread everywhere |
| unevenly distributed | amounts are concentrated in a certain area, not equal |
