GLY1880 EXAM QUESTIONS AND
ANSWERS GRADED A+ 2025/2026
A reccurence interval, (or return period) is: - ANS The length of time between events of the
same magnitude
In general the relationship between frequency and severity of Any Given natural Hazard is -
ANS An inverse relationship when one goes down the other goes up
The rapid rise in global population mostly crowded into increasingly large population centers
sets the stage for ever more destructive disasters world population is growing exponentially at a
rate of about 1.2% per year using the estimator formula for doubling time found in your book
how often does world population double - ANS Roughly every 60 years
The lithosphere which is the outermost layer of the Earth averages out to be roughly blank
kilometers thick - ANS 100
True or false continental crust is much thicker than oceanic crust - ANS True
If a rock returns to its original size and shape after a stress is removed Its Behavior is blank -
ANS Elastic

, Paleomagnetic data from the seafloor was a key piece of evidence supporting the idea of
seafloor spreading the symmetrical patterns of paleomagnetic stripes on either side of the mid-
ocean ridge indicated - ANS New ocean crust is formed at ridges and spread out in both
directions from the ridge
Earthquakes happen at ocean trenches convergent boundaries and ocean ridges divergent
boundaries but earthquakes at ocean ridges are much more blank than those at ocean trenches
- ANS shallow closer to the surface
Examine the map and figure 2.13 due to the production of new crust and rift valleys which plate
should be slowly growing larger over time - ANS African
Which of the following statements is true about the location of earthquakes and volcanoes
worldwide - ANS Most earthquakes and volcanoes are located along plate boundaries
The figure below shows a cross-section view of layers that have been disrupted by a fault this
fault is a - ANS Normal fault
If the hanging wall moves downward relative to the footwall the fault is blank - ANS Normal
A fault is an example of blank Behavior - ANS Brittle
The Shadow Zone occurs because s-waves won't pass through the - ANS Outer core
The most damaging shaking during earthquakes generally results from - ANS Surface waves
On a seismograph the blank waves will arrive first then the blank waves and then the blank
waves - ANS PS surface
