Item CL021002: The rising and falling of warm and cold air causes the circulation of air that causes wind to blow along the surface of the earth.

Which of the following describes the relationship between temperature differences, circulation of air, and wind blowing along the surface of the earth?

  1. Temperature differences cause warm air to rise and cold air to sink, which leads to circulation of the air that causes wind to blow along the surface of the earth.
  2. Temperature differences cause warm air to rise and cold air to sink, but this movement does not lead to circulation of the air, and therefore does not cause wind to blow along the surface of the earth.
  3. Circulation of the air causes the wind to blow along the surface of the earth, but the circulation is not caused by temperature differences.
  4. There is no relationship between temperature differences, circulation of air, and wind. The only cause of air moving along the surface of the earth is the rotation of the earth.
