- 1. Multiple Choice
What is the relationship between the occurrence of earthquakes and tectonic plate motion?
Tectonic plate motion causes pressure to build, leading to earthquakes.
Earthquakes cause tectonic plate motion.
Tectonic plate motion has no effect on earthquakes.
Earthquakes and tectonic plate motion are unrelated.
- 2. Multiple Choice
What causes earthquakes at convergent boundaries?
Pressure build-up as plates grind against each other.
Pressure build-up as plates push against each other.
Pressure build-up as plates move apart.
Pressure build-up as plates slide past each other.
- 3. Multiple Choice
What causes earthquakes at transform boundaries?
Pressure build-up as plates grind against each other.
Pressure build-up as plates push against each other.
Pressure build-up as plates move apart.
Pressure build-up as plates slide past each other.
- 4. Multiple Choice
How do faults cause earthquakes?
Faults release pressure by moving rocks along preexisting fault lines.
Faults cause tectonic plate motion, leading to earthquakes.
Faults create pressure by pushing against each other.
Faults have no effect on earthquakes.
- 5. Multiple Choice
What characterizes stress and strain in Earth's crust?
Stress is any force that results from gravity or plate motion, while strain is deformation caused by stress.
Stress is deformation caused by stress, while strain is any force that results from gravity or plate motion.
Stress and strain are both forces that result from gravity or plate motion.
Stress and strain have no effect on Earth's crust.
- 6. Multiple Choice
What is stress?
Stress is deformation caused by stress.
Stress is any force that results from gravity or plate motion.
Stress is the sudden release of pressure along a fault.
Stress is the movement of tectonic plates.
- 7. Multiple Choice
What is strain?
Strain is deformation caused by stress.
Strain is any force that results from gravity or plate motion.
Strain is the sudden release of pressure along a fault.
Strain is the movement of tectonic plates.
- 8. Multiple Choice
What occurs when stress that has accumulated along a fault is suddenly released?
Elastic rebound happens.
Strain is caused.
Stress is relieved.
Tectonic plate motion occurs.
- 9. Multiple Choice
How does elastic rebound happen?
Rocks along a fault are bent by pressure, then move or break suddenly and snap back to their original shape.
Rocks along a fault are stretched by tension, then move or break suddenly and snap back to their original shape.
Rocks along a fault are compressed by compression, then move or break suddenly and snap back to their original shape.
Rocks along a fault are sheared by shear stress, then move or break suddenly and snap back to their original shape.
- 10. Multiple Choice
Give an example of a type of strain that can be caused by compressional stress.
Faulting
Folding
Shearing
Extension
- 11. Multiple Choice
What causes earthquakes at divergent boundaries?
Pressure build-up as plates grind against each other.
Pressure build-up as plates push against each other.
Pressure build-up as plates move apart.
Pressure build-up as plates slide past each other.
- 12. Multiple Choice
What is liquefaction?
The sudden release of pressure along a fault.
The movement of tectonic plates.
The bending of rocks along a fault.
The process in which saturated soil temporarily loses its strength and behaves like a liquid.
- 13. Multiple Choice
What features characterize the four types of faults?
Normal faults have hanging wall moving down, reverse faults have hanging wall moving up, thrust faults have low-angle reverse movement, and strike-slip faults have horizontal movement.
Normal faults have hanging wall moving up, reverse faults have hanging wall moving down, thrust faults have low-angle reverse movement, and strike-slip faults have vertical movement.
Normal faults have hanging wall moving down, reverse faults have hanging wall moving up, thrust faults have high-angle reverse movement, and strike-slip faults have horizontal movement.
Normal faults have hanging wall moving up, reverse faults have hanging wall moving down, thrust faults have high-angle reverse movement, and strike-slip faults have vertical movement.
- 14. Multiple Choice
Explain the difference between reverse faults and thrust faults.
Reverse faults have hanging wall moving up at an angle of 45° or more, while thrust faults have hanging wall moving down at an angle of 45° or less.
Reverse faults have hanging wall moving down at an angle of 45° or more, while thrust faults have hanging wall moving up at an angle of 45° or less.
Reverse faults have hanging wall moving up at an angle of 45° or less, while thrust faults have hanging wall moving down at an angle of 45° or more.
Reverse faults have hanging wall moving down at an angle of 45° or less, while thrust faults have hanging wall moving up at an angle of 45° or more.
- 15. Multiple Choice
