Across
  1. 3. boundary where two air masses meet and weather occurs
  2. 4. all of the water on Earth (lakes, oceans, clouds)
  3. 5. when warm air stretches over a cold air mass causing steady light rain or snow
  4. 8. leaves cloud as ice crystals, melts in warm layer, refreezes (32F or colder) before hitting the ground as ice
  5. 10. dry and cold air mass
  6. 11. precipitation made of white ice crystals that fall from clouds
  7. 12. wet and warm air mass
  8. 14. system where winds blow away from high pressure (generally dry weather & clear skies)
  9. 15. mixture of liquid and frozen precipitation forming a large frozen raindrop
Down
  1. 1. all of the gases surrounding Earth (five layers)
  2. 2. when a cold air mass pushes warm air mass up causing heavy rain, thunderstorms, and snow
  3. 5. is affected by air pressure and air temperature
  4. 6. liquid precipitation in the form of water droplets
  5. 7. wet and cold air mass
  6. 9. system where winds blow towards the low pressure, and the air rises in the atmosphere where they meet
  7. 13. dry and warm air mass
