Continental Drift
Vocab for Continental Drift
| Question | Answer |
|---|---|
| Name Earth's layers | Inner Core, Outer Core, Mantle and the Crust |
| Which is thicker: Continental and Oceanic Crust | Continental Crust |
| What are seismic wave? | A seismic wave is a force of energy that channels though the Earth's crust and vibrates the ground when it passes. |
| What is the difference between Oceanic crust and Continental crust? | Continental crust is less dense then oceanic rust. Oceanic crust is made of water and continental crust is not. |
| What are the 2 kinds of mantle? | Lithosphere and Asthenosphere |
| What are the 2 kinds of crust? | Continental and Oceanic |
| What are the 2 layers of the core? | The Inner core and the Outer core |
| What is the crust made out of? | oxygen, silicon, aluminum, calcium, iron, sodium, potassium, magnesium |
| What is the mantle made out of? | silicon, oxygen, iron, magnesium |
| What is the Core made out of? | Iron and Nickel |
| Theory of Continental drift | The movements of the earth's continents. |
| Pangea | A hypothetical continent with all land masses. |
| Inner Core | A primarily solid ball made of iron and nickel. |
| Outer Core | A liquid layer outside the outer core made up of nickel and iron |
| Crust | A hard outer layer. |
| Lithosphere | The rigid outer part of the earth. |
| Asthenosphere | The upper layer of the earth's mantle. |
| Continental Crust | The relatively thick part of the earth's crust. |
| Oceanic Crust | A relatively thin part of the earth's crust. |
| Divergent boundary | A linear feature that exists between the two tectonic plates. |
| Convergent boundary | A destructive plate boundary. |
| Transform boundary | A conservative plate boundary |
| Mantle | more than two thousand miles thick and accounts for more than three-quarters of the volume of the Earth. |
| theory of continental drift | when a super continent called Pangaea drifted apart into 7 smaller continents |
| Pangaea | a super continent that existed 200 million years ago |
| lithosphere | the uppermost part of the mantle and a strong rigid layer |
| asthenosphere | upper mantle it is 100-660 kilometers thick |
| continental crust | 35-70 kilometers thick |
| oceanic crust | 7 kilometers thick |
| divergent boudaries | where tectonic plates move apart <-- --> |
| convergent boudaries | where two plates are coming together --> <-- |
| transform boundary | where plates slide past each other in opposite directions --> <-- |
