return to earth as acidic rain, snow, fog, or dust they can cause a lot of problems.

On a pH scale, a substance with a pH of less that 7 is considered an acid. The lower the number is the more acidic a substance is. If a substance has a pH of more that 7 it is call a base. The higher the number the more basic a substance is, the highest being 14. For a

substance with a Ph of 7 it is a neutral substance. Normal rainfall has a pH of 5.6 to 6.5, even though it is slightly acidic it doesn't affect the environment. With the release of more sulfur dioxide (SO2) and nitrogen oxide (NOX) into the atmosphere the pH of rainfall is dropping. The lowest recorded pH of rainwater was in Wheelin

If we don't deal with acid rain, all of the materials that we have built, cars or structures, could be in jeopardy. When acid rain falls on the surface of metals, it is responsible for the acceleration of corrosion in the metal. Acid rain can also affect the paint job on your car or house. The acid rain can damage and wear away the paint. Acid rain can wear away stone also. It can wear away stone like, marble and limestone, fairly quickly. If acid rain falls in the area where you live, the value of everything is at risk. Acid rain can decrease the value to the community all the structures in the community. Wearing away the building and

Acid rain is more of a threat than people thing. If nothing is done about it, it can

g, West Virginia in the fall of the year 1978. The rainwater then had a recorded pH of 2.0. To compare with something else, a bottle of lemon juice has a pH of 2.1. (5)

Fish are not the only ones affected by acid rain, trees are also affected by acid rain. According to the 1990 National Acid Precipitation Assessment Program report that was sent to Congress, acid rain was found to kill off trees causing a decline in the population. From the 1960s until now the population of red spruce has been cut in half in New York, Vermont, and New Hampshire. Acid deposition is the main cause to why the red spruce population has been cut in half. Also, sugar maple has seen a drop in its population. A lot of other trees are feeling the affects of acid rain and deposition. In addition to feeling the affects of acid rain a lot of trees are feeling the affects of drought and of insect infestation which also help in the decline of trees. (6)

Because of this the eastern part of the United States is the harder hit when it comes to acid rain. The western coast of the United States does not have to worry as much of acid rain because their weather comes from the Pacific Ocean. The weather pattern across the United States goes from west to east. This means that the clouds have not had a chance to mix with the sulfur dioxide and nitrogen oxide from the electrical utilities, transportation vehicles and industries yet. (6)
