Science (The Dynamic of Earth)

1. a line which may be visible or not that occurs on Earth's surface
3. the point on Earth's surface directly above focus
4. geological faults where the earthquake originates
6. a fault in which the hanging wall moves down
8. first part is the area where the fault occured
11. a large wave that moves up and down
15. refers to the forces and events that lead to a large structural deformation
16. a fault in which two blocks of the crust slide past each other on the same place
17. a molten rock
19. are classified into two: surface waves and body waves
24. can detect the existence of a fault by studying the distances between rocks
26. also called ground rolls
30. a natural phenomena that is a sudden, violent shifting of massive plates underneath the Earth's surface

2. an Irish civil engineer and scientist who studied the earthquake's motion
5. a mountain that opens downward to a reservoir
7. considered as the longest mountain chain
9. traverses to the direction of the propagation but with no vertical motion
10. located with either in the PRoF or the Alpide Belt
12. refers to the blocks of crust above the fault
13. Japanese word for tidal wave or big wave
14. the process and phenomenon associated with the surficial discharge of molten rocks and other materials
16. travels approximately 2.5-4km per second and can only travel through solid materials
18. travels fastest at the speed from 4km to 8km per second
20. a crack across which the rocks have offset first
21. propagation of elastic waves through Earth and other planet-like bodies
22. He introduced the Richter Scale back in 1934
23. is the block of crust below the fault
25. are areas where heat or rocks in the mantle are rising towards the Earth's surface
27. are locations on Earth's surface that has experienced active volcano activties
28. also called thrust fault
29. occurs when matter such as magma circulates
