  1. The Atmosphere Air Pollution

  2. Most air pollution is the result ofburning fossil fuels……. • Coal • Oil • Gasoline • Diesel fuel

  3. ½ of the air pollution comes from cars that burn gas and diesel. • ¼ comes from factories and power plants that burn coal and oil.

  4. This forms 2 main types of air pollution SMOG and ACID RAIN

  5. SMOG • Today most cities experience photochemical smog, caused by the action of sunlight on chemicals.

  6. How smog is formed….. • Nitrogen combines with Oxygen = nitrogen oxides. • Nitrogen oxides combine with hydrocarbons (from burning fossils fuels). • In the presence of sunlight they form a mix of chemicals called photochemical smog.

  7. SMOG FORMATION

  8. Harmful Effects of Photochemical Smog • Lung irritation- • Harmful to plants • Damages paint, rubber, and some plastics. • Learn more!!EFFECTS

  9. ACID RAIN • Rain is naturally slightly acidic, but rain that contains more acid than normal is known as acid rain.

  10. ACID RAIN • The smoke and fumes from burning fossil fuels rise into the atmosphere and combine with the moisture in the air to form acid rain. • The mainchemicals in air pollution that create acid rain are sulfur dioxide and nitrogen oxides. • This forms a mild solution of sulfuric acid and nitricacid. • Rainwater, snow, fog, and other forms of precipitation containing those mild acids fall to the earth as acid rain.

  11. ACID RAIN FORMATION

  12. Harmful Effects of Acid rain • Damaging to buildings and statues. • Harmful to plants, especially pine trees. • Harmful to lakes and ponds. Acid rain can make water so acidic that plants, amphibians, fish, and insects can no longer survive in it. • Can even be harmful to humanhealth.

  13. Damage done by Acid Rain

  14. In Conclusion…… • Burning fossil fuels can create both photochemical smog and acid rain. • They are both harmful to people and the environment. • Click HERE to learn more from a short video.
