ESS 105 - quiz 1 Answered Correctly Graded A+
natural hazard - Answers a natural process that poses a threat to human life or property
risk - Answers the probability that a community will be subject to injury or loss due to hazardous events
natural disaster - Answers natural event that causes significant damage to life or property
factors making disasters more prevalent - Answers population and infrastructure
earthquake - Answers The shaking that results from the movement of rock beneath Earth's surface.
Hypocenter - Answers the point within the earth where an earthquake rupture starts
focus - Answers The point beneath Earth's surface where rock breaks under stress and causes an
earthquake
Epicenter - Answers Point on Earth's surface directly above an earthquake's focus
fault plane - Answers surface of contact along which blocks on either side of a fault move
fault scarp - Answers a cliff created by movement along a fault. it represents the exposed surface of the
fault prior to modification by weathering and erosion
elastic rebound theory - Answers theory that rocks that are strained past a certain point will fracture
and spring back to their original shape
divergent boundary - Answers A plate boundary where two plates move away from each other.
convergent boundary - Answers A plate boundary where two plates move toward each other.
transform boundary - Answers A plate boundary where two plates move past each other in opposite
directions
normal fault - Answers a fault in which the hanging wall moves down relative to the footwall
reverse/thrust fault - Answers a type of fault where the hanging wall slides upward; caused by
compression in the crust
strike-slip fault - Answers a type of fault where rocks on either side move past each other sideways with
little up or down motion
Compressional Waves (P waves) - Answers fastest waves, small amplitude
Shear Waves (S waves) - Answers large amplitude and high frequency
surface waves - Answers slowest but largest amplitude
