Geology Criss-Cross puzzle

2. Fluid flow that occurs spontaneously in the mantle which carries heat from the interior to the Earth’s surface.
4. Secondary waves which are slower but much stronger.
6. Polymeric material that has the capability of being shaped or molded.
7. High wave caused by a displacement of a large volume of water. Generally produced by earthquakes or volcanic eruptions.
8. The idea of an earthquake magnitude scale was first developed by Charles…
9. The study of magnetic rocks and sediments to record the history of the magnetic field. Was used to prove the spreading of tectonic plates.
12. Primary wave which is the fastest seismic wave.
16. Rocky outer part of the Earth. Made up of the crust and the top part of the upper mantle.
17. Graph output by a seismograph.
20. When all the continents used to be together forming one supercontinent.
21. The most rigid part of the mantle.

1. When two plates move away from each other.
3. When two tectonic plates slide past each other.
5. When plates are pushed together.
10. Proposed the theory of continental drift.
11. Device that responds to ground noises which helps to detect and record data of an earthquake.
13. Ductile, less rigid, upper part of the mantle.
14. Place inside the Earth's crust where an earthquake originates.
15. Most dense, solid part of the core.
18. Made up of two layers, it's found between the core and the crust.
19. Point found above the focus.
