Tectonics Revision

4. This type of magma occurs at destructive plate boundaries
8. This model identifies the root causes of vulnerability
10. A flow composed of rock, mud and water originating on the flanks of a volcano
11. The name given to a plate boundary where new crust is generated
12. The process whereby new oceanic plates are pushed apart by the force of the mid-ocean ridge
13. This model shows how an overlap of a natural hazard and a vulnerable population can result in a disaster
14. This type of explosive eruption occurs when magma heats ground or surface water
17. These are produced by earthquakes in the crust and travel through the Earth's layers
20. Long, curved chain of oceanic islands associated with intense volcanic and seismic activity
21. This measures the total energy released by an earthquake at the moment it occurs
22. Oceanic crust is destroyed here
23. This is increasingly seen as a major driving force for plate movement
24. A model that shows how a country or region might respond following a hazard event

1. The study of past changes in the Earth's magnetic field, determined from minerals contained in oceanic crust
2. The name given to a tsunami warning system found across the Pacific
3. A measure of the size or magnitude of a volcanic eruption
5. The name given to a plate boundary where crust is neither created or destroyed
6. A flood caused by the melting of an icecap or glacier by a volcanic eruption
7. This type of magma occurs at constructive plate boundaries
9. The name given to a plate boundary where crust is destroyed
15. The name given to smaller earthquakes that follow a large earthquake
16. The ability to protect lives, livelihoods and infrastructure from destruction, and to restore areas after a natural hazard has occurred
18. This volcano caused widespread disruption across Europe in 2010
19. The ability to anticipate, cope with, resist and recover from a natural hazard
