Geology 101 UA Exam 3 Questions &
Answers (Grade A+)
Hazards Associated with Earthquakes -
correct answer ✅-Ground Shaking
-Tsunami
-Landslide
-Disease and starvation
-Liquefaction
-Fire
Causes of Earthquakes -
correct answer ✅-sudden slip on a fault
-sudden formation of a new fault
Types of Faults -
correct answer ✅-Normal Fault- hanging-wall block moves down
relative to the footwall block
-Reverse Fault- hanging wall block moves upwards
-Transform Fault- one block moves to the right relative to the other
block
,Geology 101 UA Exam 3 Questions &
Answers (Grade A+)
Seismograph -
correct answer ✅-an instrument that can record the ground
motion for an earthquake
-automatically record earthquake activity
-can detect motion not noticed by humans
-can tell us an earthquake is occurring
Hypocenter and the Epicenter -
correct answer ✅-Hypocenter- the point below the earth's surface
where the energy is produced in an earthquake
-Epicenter- directly above the surface of a focus in an earthquake
-Fault- a fracture in the Earth's surface on which sliding occurs
Fault Displacement -
correct answer ✅-the amount of movement or slip across a fault
plane
Fault Scarp -
correct answer ✅-a small step on the ground surface where one
side of a fault has moved vertically in respect to another
, Geology 101 UA Exam 3 Questions &
Answers (Grade A+)
Stress -
correct answer ✅-a push, pull, or shear applied to a material
Elastic Strain -
correct answer ✅-a change in shape of a material that disappears
instantly when stress is removed
Friction -
correct answer ✅-the force that resists sliding on a surface
Stick-Slip Behavior -
correct answer ✅-stop-start movement along a fault plane caused
by friction (stick), which prevents movement (displacement) until
stress builds up sufficiently (slip)
Elastic-rebound Theory -
correct answer ✅-the concept that earthquakes occur when rock
elastically bends until it fractures; the fracturing generates
earthquake energy and decreases the elastic energy stored in the
rock
