Across
- 1. temperature, precipitation, and wind.
- 3. Organic chemicals that easily become vapors, contributing to air pollution.
- 6. pollution found inside buildings, comes from sources like chemicals or poor ventilation.
- 8. weather patterns in an area.
- 10. Pollutants emitted directly from a source.
- 13. air pollution from burning coal, has soot and sulfur compounds. (Gray-Air Smog)
- 15. U.S. legislation aimed at reducing air pollution and protecting air quality.
- 16. acidic particles or gases (dry) or acidic rain/snow (wet) falling to the ground.
- 17. The thinning of the ozone layer caused by chemicals like CFCs. (Stratospheric)
- 18. radioactive gas that comes from the ground and can cause lung cancer.
- 20. acid formed when sulfur dioxide reacts with water in the atmosphere.
- 21. layer of the atmosphere above the troposphere.
- 22. system that lets companies to trade permits for pollution emissions.
- 23. layers of gases surrounding Earth.
- 24. Smog made from sunlight reacting with pollutants like emissions that come from cars. (Brown-Air Smog)
Down
- 2. weather conditions when warm air traps cooler air below, concentrates pollution.
- 4. made from nitrogen oxides and water, leads to acid rain.
- 5. toxic chemicals in photochemical smog that affect the health of plants and humans.
- 7. area in the stratosphere with high ozone concentrations that absorb UV radiation.
- 9. harmful substances in the air.
- 11. lowest layer of the atmosphere, this is where weather occurs
- 12. gas released from burning fossil fuels, leads to acid rain.
- 14. solid or liquid particles that are suspended in the air.
- 19. Pollutants made when primary pollutants react in the atmosphere.
