Across
- 4. The sudden release of energy within the Earth's crust that causes shaking of the ground
- 7. The transfer of heat by the movement of fluids
- 11. An igneous rock created by low viscosity magma and high temperatures
- 12. A hill or ridge with a gentle slope on its back and a steep slope on its front
- 13. An alternative name for a composite volcano
- 14. A four-digit number that represents a certain rectangular area within a map
- 16. A fault where two tectonic plates move horizontally past each other
- 18. Rocks formed from magma with a cool, glassy appearance
- 19. One of four spheres; the sphere of rocks, dirt and soil
- 21. The point on the Earth's surface directly above the focus
- 23. They travel only through solids, not through liquids
- 26. The process where the movement of tectonic plates and the compression of rocks can create faults, volcanic mountains as well as fold and lift the Earth's crust

Down
- 1. It is called lava after reaching the Earth's surface
- 2. The breakdown and transportation of the Earth's surface caused by running water, rain and wind
- 3. Limestone and sandstone are rocks formed from the compaction of __________ material
- 5. A building technique where counterweights are used to balance shaking caused by an earthquake
- 6. A device that monitors gas emissions and heat coming from a volcano that can help predict an eruption
- 8. A lithospheric structure where material inside the Earth erupts to the surface
- 9. The point in the Earth's crust where an earthquake begins
- 10. A word that describes a volcano that is currently inactive but may erupt in the future
- 11. A building technique where the building is lifted above the ground (by a spring etc.) to prevent earthquake damage
- 15. A fast moving current of hot gas and rocks emitted from a volcano
- 17. One of numerous ways to categorise the factors that affect the Earth
- 20. A word that describes rocks changed through the heat and pressure of the Earth's crust
- 22. They travel through solids and liquids
- 24. The process where weathered rocks are carried away from their source by wind, waves or rivers and dumped elsewhere
- 25. This type of volcano is prominent in Hawaii
- 28. Dense, rocky material under the Earth's crust
- 31. A fault where the compression of rocks forces the tectonic plate on one side of the fault to move up and over the other side
