Down
- 1. A sleeping but very active volcano.
- 2. When two lithospheric plates collide.
- 4. Scientist who study the formation of Earth's physical structure.
- 6. A device the measures the intensity of an earthquake.
- 7. Once magma hits the Earth's surface it becomes ________.
- 9. A theory explaining the structure of the earth's crust and many associated phenomena as resulting from the interaction of rigid lithospheric plates which move slowly over the underlying mantle.
- 11. A crack in the Earth's surface
- 12. the rigid outer part of the earth, consisting of the crust and upper mantle.
- 15. Giant waves caused by earthquakes or volcanic eruptions under the sea.
- 16. the upper layer of the earth's mantle, below the lithosphere that plate move on.
- 17. The edges around tectonic plates where plates meet.

- 21. the location on the surface of the Earth directly above where the earthquake starts.
- 22. The study of movement underneath the Earth's crust.
- 25. volcanoes that have a recent history of eruptions; likely to erupt again.
