Chapter 4, Sec. 4

2. Amount of force per area put on an object
Stress
Amount of force per area put on an object

3. Rocks can change shape due to stress

4. Three types of stress:
Compression
Tension
Shear

8. FOLDING Rock layers bend due to stress
Assume most rocks are laid down horizontal

12. The line along which rocks break and move
FAULTS
The line along which rocks break and move

13. Caused by tension forces Hanging wall moves down
Normal Faults
Caused by tension forces
Hanging wall moves down

20. Reverse Faults
Caused by compression forces
Hanging wall moves up

25. Opposing forces cause rock to break
Strike-slip Faults
Opposing forces cause rock to break
Move horizontally
