Earthquakes

1. The point on the Earth's surface directly above the earthquake's origin.
5. A force that tends to deform rock, leading to strain.
7. The study of the processes that shape the Earth's crust, including plate movement.
10. A type of fault where plates slide past each other horizontally.
13. A measure of the total energy released by an earthquake.
14. The central part of the Earth, consisting of a solid inner part and a liquid outer part.
15. Large rigid sections of the Earth's lithosphere that move slowly.
17. The layer of the Earth between the crust and the outer core.

2. A type of reverse fault where the hanging wall moves up over the footwall due to compression.
3. The deformation or change in shape of rock resulting from stress.
4. The point within the Earth where the earthquake rupture begins.
5. Relating to or caused by earthquakes or Earth vibration.
6. An instrument used to detect and record ground motion caused by seismic waves.
8. The outermost solid layer of the Earth.
9. The process where one tectonic plate moves under another and sinks into the mantle.
11. A type of fault where the hanging wall moves down relative to the footwall due to tension.
12. A fracture in the Earth's crust where blocks of rock move past one another.
16. Molten rock found beneath the Earth's surface, often associated with volcanic activity.
