Across
- 2. supercontinent formed 250 million years ago
- 6. a weaker place in the middle of a plate where magma comes up and volcanoes form
- 9. the place where the earthquake is felt at the surface
- 10. a scale that measures the strenght of an earthquake
- 13. the flow of magma in the mantle that causes plates to move
- 17. a big space filled with magma under the volcano
- 18. boundary where two plates move apart
- 20. when lava escapes the volcano via a weaker spot in the volcano
- 21. the ocean around which we can find the ring of fire
- 22. a famous example of a transform boundary in the USA
Down
- 1. the continental plate is made from this material
- 3. in this part of the mantle, convection currents take place
- 4. the combination of the crust and the solid part of the mantle
- 5. this plate is the thinnest
- 7. a big wave formed when an earthquake takes place in the water
- 8. short-term help given when a disaster took place
- 11. at this boundary one can find explosive volcanoes
- 12. this formed in the middle of the ocean at the divergent boundary
- 14. the process in which one plate goes underneath the under
- 15. magma at the earth's surface
- 16. when a volcano explodes, it is called an ...
- 19. a scale that measures the damage an earthquake causes
