When two tectonic plates move away from each other, it is called? |
| 6. |
What type of boundary is this: two tectonic plates slide past each other. |
| 7. |
When magma rises through the lithosphere to the bottom of the ocean and forms a undersea volcano which eventually rises to the surface of the Earth, creating a volcanic island. |
| 8. |
Conventional currents flow in the mantle, and a product of this is Earth's magnetic field. What is this idea called? |

| 4. |
Something which is formed when Earth's lithosphere pulls apart. |
| 9. |
The idea that the lithosphere is split up into large, moving plates (consisting of both continental and oceanic crust). |
| 10. |
This is formed where one tectonic plate goes under another. They are also the deepest parts of the ocean. |
| 11. |
