Science
Across
- 3. An instrument used to measure air pressure
- 4. The spinning of a planet or moon on its axis
- 6. The condition of the atmosphere at a particular place at a particular time
- 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
- 12. The change that Earth's rotation causes in the motion of objects
- 13. A region of charged particles, ot ions, in Earth's atmosphere that overlaps the lower thermosphere
- 15. The layer of Earth's atmosphere above the troposphere
- 16. A day that marks the beginning of spring or autumn; a day on which the length of daylight and darkness are approximately equal
- 17. The lowest layer of Earth's atmosphere, where most weather occurs
- 19. The lower portion of Earth's mantle; the layer of Earth's atmosphere immediately above the stratosphere
- 20. A colorful display of light in the ionosphere, produced when charged particles from the sun are attracted to Earth's magnetic poles
- 21. The outermost layer of Earth's atmosphere
- 24. A wind that blows over a short distance
- 26. A local wind that occurs when cooler air over the water flows toward the land
- 27. A belt of high-speed wind in the upper troposhere
Down
- 1. The movement of one body around another
- 2. A wind that blows over long distance from a specific direction
- 5. The pressure caused by the weight of a column of air in Earth's atmosphere
- 7. A wind system that shows a seasonal reversal of direction
- 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
- 10. The layer of gases that surrounds Earth
- 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
- 14. A warm region between latitude 23.5° south and latitude 23.5° north
- 18. A region of ozone concentration in the stratosphere
- 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
- 23. The mainly horizontal movement of air from areas of higher pressure to areas of lower pressure
- 25. A local wind that occurs when cooler air over land moves toward water
