Across
- 8. carbon based energy sources such as coal, oil, and natural gas
- 13. dense air sinks, causing dry and clear weather
- 14. less dense air rises, causing wet and overcast weather
- 15. tectonic plates slide past each other, causing earthquakes
- 18. the process that moves carbon between the biosphere, hydrosphere, geosphere, and atmosphere
- 19. layer of the Earth that we live on
- 20. forms over land when a cool, dry high-pressure air mass collides with a warm low-pressure air mass
- 21. brings rainstorms and leaves humid, warm weather behind
Down
- 1. burning that releases carbon dioxide into the atmosphere
- 2. soaking in, or taking greenhouse gases out of the atmosphere
- 3. day-to-day conditions in the atmosphere
- 4. continuous movement of water between the ocean, atmosphere, and land
- 5. brings thunderstorms and leaves overcast and colder weather behind
- 6. the circular motion of liquids or gases caused by density differences in the wind in the atmosphere, ocean currents, and asthenosphere
- 7. gases being released into the atmosphere can result from deforestation, meteor impacts, and cellular respiration
- 9. ocean current that brings warm water from the equator
- 10. building or expanding cities to accommodate the increasing population
- 11. tropical cyclone that forms in areas of low pressure over warm tropical oceans
- 12. tectonic plates move toward each other, volcanic islands, and trenches
- 16. tectonic plates move away from each other, creating rifts and ridges
- 17. Fast narrow air current that blows from west to east
