Acid Rain Presentation

  1. 1. By Jason Huang, Jordan Bingham, and Meiwei Xiao
  2. 2. How is acid rain created? Factories produce bad things called sulfur dioxide and nitrogenoxide and release them into the air (yellow dots in picture)When sulfur dioxide and nitrogen oxide combine with the air acidrain is created
  3. 3. Sulfur Dioxide and Nitrogen Oxide• Sulfur dioxide and nitrogen oxide are pollutants• They escape through smokestacks, chimneys, and tailpipes• Over 20 million tons of sulfur dioxide and nitrogen oxide move into the atmosphere each year
  4. 4. Sulfuric Acid and Nitric Acid• Sulfur dioxide and nitrogen oxide can fall to earth as dust• Sulfur dioxide and nitrogen oxide can become trapped by moisture in clouds – When combined with water they form acid (sulfuric acid and nitric acid) – They then fall to earth in rain, snow, sleet, hail, or fog (acid rain)
  5. 5. Acid Rain Harms Ecosystems• A little acid rain is normal• A lot of acid rain harms a lot of ecosystems  Especially aquatic ones• Some animals are more sensitive to acid then others  Adult wood frog can live in water with a pH level of 4 but rainbow trout and smallmouth bass can’t live below pH of 5• Too much acid rain in soil might harm plants’ root systems• Acid rain damages leaves on trees and changes soil
  6. 6. Solution• Burning fossil fuels create pollutants that form acid rain• We use fossil fuels to heat, cool, and light our houses and fossil fuels run cars, cook food, and run machinery• We should walk or bike instead of drive, carpool, turn down heat in our homes, and turn off lights in our homes!
