  2. 4. The spinning of a planet or moon on its axis
  3. 6. The condition of the atmosphere at a particular place at a particular time
  4. 9. The regions between latitude 23.5° north and latitude 66.5° north, and between latitude 23.5° south and 66.5° south, which are generally cooler than the tropics
  5. 12. The change that Earth's rotation causes in the motion of objects
  6. 13. A region of charged particles, ot ions, in Earth's atmosphere that overlaps the lower thermosphere
  7. 15. The layer of Earth's atmosphere above the troposphere
  8. 16. A day that marks the beginning of spring or autumn; a day on which the length of daylight and darkness are approximately equal
  9. 17. The lowest layer of Earth's atmosphere, where most weather occurs
  10. 19. The lower portion of Earth's mantle; the layer of Earth's atmosphere immediately above the stratosphere
  11. 20. A colorful display of light in the ionosphere, produced when charged particles from the sun are attracted to Earth's magnetic poles
  12. 21. The outermost layer of Earth's atmosphere
  13. 24. A wind that blows over a short distance

  1. 1. The movement of one body around another
  2. 2. A wind that blows over long distance from a specific direction
  3. 5. The pressure caused by the weight of a column of air in Earth's atmosphere
  4. 7. A wind system that shows a seasonal reversal of direction
  5. 8. A process in which gases in Earth's atmosphere, such as water vapor and carbon dioxide, allow visible light to pass through but absorb reradiated infrared radiation that warms the lower atmosphere
  6. 10. The layer of gases that surrounds Earth
  7. 11. The regions from latitude 66.5° north to the north pole, and from latitude 66.5° south to the south pole, which are generally cold
  8. 14. A warm region between latitude 23.5° south and latitude 23.5° north
  9. 18. A region of ozone concentration in the stratosphere
  10. 22. The day that marks the start of summer or winter; the day when the sun is directly overhead at latitude 23.5° north or latitude 23.5° south
  11. 23. The mainly horizontal movement of air from areas of higher pressure to areas of lower pressure
  12. 25. A local wind that occurs when cooler air over land moves toward water
