Why do earthquakes of similar size often have such large differences in their destructiveness? Why are
  they so different in the number of people they kill? What will be an ideal response?

Question 2

Compare the continental crust with oceanic crust in terms of composition and thickness. What will be an ideal response?

Answer to Question 1

Earthquakes do more damage in places where the population density is high and the structures are not
especially well built. More people are killed if they are out on the road and at work than if they are
home in bed.

Answer to Question 2

Continental crust is complex, consisting of all rock types, but is usually described as granitic. It
averages 35 km thick. Oceanic crust is comparatively simple, consisting of gabbro in its lower part and
overlain by basalt. Its thickness ranges from 5 to 10 km.
