Plate Tectonics

4. The process where new oceanic crust forms at mid-ocean ridges and moves outward.
5. A boundary where two continental plates push together to form mountains.
7. Magnetic patterns in rocks that show evidence of plate movement over time.
8. An island nation on a constructive plate boundary, formed by volcanic activity.
12. The liquid metal layer surrounding the Earth’s solid centre.
13. The scale used to measure the magnitude or energy released by an earthquake.
14. Boundaries within the Earth where the composition or density of materials changes.
16. The scale that measures the effects and damage caused by an earthquake.
17. The thick layer of hot, semi-molten rock beneath the crust.
18. A type of plate boundary where plates slide past each other.

1. Efforts made months or years after a disaster to aid recovery and rebuild communities.
2. Effects of a hazard on people’s lives, health, and wellbeing.
3. The effects of an event on ecosystems, habitats, and natural resources.
6. The line where two tectonic plates meet.
9. The Earth’s thin, solid outer shell where we live.
10. A type of boundary where one plate is forced under another.
11. The financial costs or benefits resulting from a natural disaster or event.
15. Actions taken right after a disaster to save lives and reduce damage.
18. A type of boundary where plates move apart and new crust is created.
19. The hottest layer at the very centre of the Earth, made mostly of iron and nickel.
