Acid Rain

"The biggest culprit is the burning of fossil fuels by coal-burning power plants, factories, and automobiles" (National Geographic, 2013).

ACID RAIN

"Most sulfur dioxide comes from power plants that use coal as their fuel. These plants emit 100 million tons of sulfur dioxide, 70% of that in the world. Automobiles produce about half of the world's nitrogen oxide" (ThinkQuest, n.d.)."The pH of 'normal' rain has traditionally been given a value of 5.6. However scientists now believe that the pH of rain may vary from 5.6 to a low of 4.5 with the average value of 5.0" (Ophardt, 2003).

Acid Rain = "A mixture of wet and dry deposition (deposited material) from the atmosphere containing higher than normal amounts of nitric and sulfuric acids. The precursors, or chemical forerunners, of acid rain formation result from both natural sources, such as volcanoes and decaying vegetation, and man-made sources, primarily emissions of sulfur dioxide (SO2) and nitrogen oxides (NOx) resulting from fossil fuel combustion" (EPA, 2012).

YOU CAN REDUCE ACID RAIN

The effects of acid rain can be seen throughout Washington D.C.
