At the beginning of this unit you agreed or disagreed with statements about earthquakes. Not all of the statements were true. Now that you have completed the unit, carefully think about each statement again then decide whether you agree or disagree with the statement based on what you have learned. How many of your responses changed?

1. Earthquakes can occur anywhere, although they are more likely in certain areas. (Agree / Disagree).
   
   Earthquakes can occur anywhere. They are most common where tectonic plates interact, but they can also occur anywhere where there is a fault. See "E1 - Earthquakes and Faults/What Causes an Earthquake?" for more information.
2. Earthquakes are caused by the rapid release of stored energy in rocks. (Agree / Disagree)
   
   See "E1 - Earthquakes and Faults/What Causes an Earthquake?" for more information.
3. Earthquake waves all travel at the same speed. (Agree / Disagree)
   
   P, S, and surface waves all travel at different speeds. See "E2 - Earthquakes and Waves/Seismic Waves" for more information.
4. Most earthquakes occur at fairly shallow depths below the Earth's surface. (Agree / Disagree)
   
   See "E3 - The Strength of Earthquakes/Depth of an Earthquake" for more information.
5. Only one data recording station is necessary in to accurately determine where an earthquake has occurred. (Agree / Disagree)
   
   A minimum of three data recording stations are necessary in order to accurately determine the location of an earthquake. See "E3 - The Strength of Earthquakes/Locating an Earthquake" for more information.
6. Most large earthquakes occur around the rim of the Pacific Ocean. (Agree / Disagree)
   
   See "E3 Ð The Strength of Earthquakes/The Largest Earthquakes" for more information.
7. The density of rocks on the Earth’s surface is less than the density of material in the Earth’s interior. (Agree / Disagree)
   
   See "E4 - Seismic Waves and the Earth's Interior/Early Indications" for more information.
8. The strongest earthquakes also cause the most fatalities. (Agree / Disagree)
   
   Many factors such as distance from hypocenter, time of day, construction materials and techniques, etc. can greatly influence the number of casualties. See "E5 - Living with Earthquakes/Factors Affecting Earthquake Damage/Activity: Fatalities and Earthquake Magnitude" for more information.
9. Indonesia has more high fatality earthquakes than any other country in the world. (Agree / Disagree)
   
   China has more high fatality earthquakes than any other country in the world. See "E5 - Living with Earthquakes/Factors Affecting Earthquake Damage/Activity: Fatalities and Earthquake Magnitude" for more information.
10. Tsunamis are large, destructive waves that can pass virtually unnoticed in the open ocean. (Agree / Disagree)
    
    See "E5 Ð Living with Earthquakes/Related Causes of Damage - Tsunamis" for more information.
11. Scientists are now able to predict when an earthquake will occur with an accuracy ranging from a few hours to a few days. (Agree / Disagree)
    
    Short-term prediction of earthquakes is not reliable or accurate at this time. See "E5 - Living with Earthquakes/Predicting Earthquakes" for more information.
