The San Andreas fault is a
a.
Right-lateral strike slip fault

The weak rock layer upon which the crust and upper mantle “float” is called the:
a.
Asthenosphere
7.
The location within the earth where rupture first starts in an earthquake is called the:
a.
Hypocenter
8.
As the confining pressure on a rock increases, the strength of the rock:
a.
Increases
9.
The boundary between the crust and the mantle is called:
a.
The moho
10. The number of natural disasters associated with earthquakes appears to be:
a.
Staying about the same
11. Continental crust is generated in:
a.
Subduction zones
12. Oceanic crust is generated in:
a.
Ocean spreading centers
13. Which of the following is characteristic of convergent plate boundaries:
a.
Deep earthquakes
b.
Large-scale thrust faulting
c.
Volcanism
14. The thickness of the lithosphere:
a.
Increases with increasing distance from a mid-ocean ridge
15. The fault indicated by the red line is a:
a.
b.
Thrust fault
16. The topography shown here is indicative of:
a.
b.
Normal faulting
c.
A continental hot spot
d.
A triple junction
17. Which of the following is NOT associated with a mantle hot spot
a.
Andes
18. The location of the earth’s surface directly above where the rupture first starts in an
earthquake is called:
a.
Epicenter
19. As the temperature of a rock increases, the strength of the rock:
a.
Decreases
20. The fault indicated below can be described as:
a.
b.
Left lateral strike slip fault
21. Which of the following is NOT a major contribution of seismology to the development of
plate tectonic theory:
a.
The observation of magnetic stripes on the seafloor
Types of faults
1.
Dip-slip fault movements
i.
Identify the hanging wall by placing a finger on the fault and moving up.
That would be the hanging wall.
b.
Normal fault
i.
When the hanging wall moves down relative to the footwall
1.
Tension (Rocks move apart or diverge)
c.
Reverse fault
i.
When the hanging wall moves up relative to the footwall
1.
Compression (rocks move towards each other or converge)
2.
Strike-slip fault movements
a.
Rocks move horizontally
b.
Usually found at transform plate boundaries
i.
Left lateral strike slip fault
1.
If you straddle the fault the left side is closest to you
ii.
Right lateral strike slip fault
1.
If you straddle the fault the right side is closest to you
3.
Thrust faults
a.
Same movement as a reverse fault but it is a low dip angle.
Potential Prelim Questions
1.
The presence of water
a.
Tends to weaken a fault
2.
Hawaii DOES NOT lie on:
a.
A divergent plate or a convergent plate or a transform fault (It lies on a hot spot)
3.
The Afar region of NE Africa is an example of tectonic plate triple junction where:
a.
Three plate boundaries converge
