When you are finished with this topic, you should be able to answer these questions:

  1. What latitudinal factors can affect the amount of solar radiation arriving at the surface of the earth?
  2. How does uneven heating of the earth's surface lead to development of large-scale wind belts?
  3. What is the Coriolis effect and what causes it?
  4. What causes air to be unstable?
  5. What are the differences between warm and cold fronts?
  6. How are tornadoes formed?
  7. Why does the greatest concentration of tornadoes occur in the central U.S.?
  8. What conditions are necessary for the formation of a hurricane?
