10. Most of the material moved by volcanoes is from the few, big ones rather then from the many, little ones. Most of the material moved downhill in landslides is in the many, little ones rather than the few, big ones. In comparing the importance of the few, big earthquakesto the many, little earthquakes, are earthquakes more like volcanoes (the few big ones matter most) or like landslides (the many little ones matter most)? A) The many, little earthquakes matter most (like landslides). B) Earthquakes don’t do any damage, just like volcanoes and landslides. C) The few, big earthquakes matter most (like volcanoes). D) The few, big earthquakes are exactly as important as the many, little earthquakes (exactly halfway between volcanoes and landslides). E) All earthquakes have been retribution for the Simpsons.Feedback: An increase of 1 in earthquake magnitude increases ground shaking about 10-fold, increases energy release about 30-fold, and decreases frequency about 10-fold; the 30-fold increase in energy more than offsets the 10-fold decrease in frequency of occurrence. We wish earthquakes did no damage, but the millions of people who have been killed in earthquakes over the centuries would, if they could, testify to the damage done by earthquakes. And historical records of earthquakes clearly preceded the Simpsons.Correct Answer(s):C Points Earned: 1.0/1.0 11. The New Madrid Fault Zone in Missouri has had some surprisingly big earthquakes. A magneto-hydro-astronomer at a small university near the fault zone reports that the gravitational effects of the coming alignment of several planets, together with the weakening of the magnetic field, will cause a giant earthquake on the fault zone on Wednesday morning between 1 and 4 am.
