Acid rain is made when sulfur dioxides mix with nitrogen oxides to form acids. The acids then can come back down out of the atmosphere in either a dry or a wet form. Both of these have proven devastating to both aquatic animals and forests. Billions of dollars have been spent to correct and try to fix what acid rain had done to buildings and monuments. Acid rain also has its toll on the health of us humans.

Acid rain is rain that is more acidic than normal. Acid rain is a complicated problem. Caused by air pollution, acid rain's spread and damage involves weather, chemistry, soil, and the life cycles of plants and animals on the land and from acid rain in the water. Scientists have discovered that air pollution from the burning of fossil fuels is the major cause of acid rain. Power plants and factories burn coal and oil.
Acid rain is the deposition of dry (acidifying gases and particles) and wet (snow, rain, fog, sleet, dew or cloud water) acidic components. Acid rain has many negative effects in the world including harm to wildlife, humans, trees, agriculture, and even architecture. If pollution, the major cause of acid rain, were reduced, the amount of acid rain would decrease significantly. Acid rain is formed when the acids from combustion are released into the atmosphere. During combustion, nitric oxides and sulfur dioxides are converted into nitric acid and sulfuric acid.
In some cases, acid rain is caused when industrial fumes mix with moisture in the atmosphere. Acids are then carried in clouds for long distances before they are deposited through rain, which indicates that forests and lakes far away from factories may be damaged by acid rain. Another significant cause of acid rain is automobile exhaust. Research has shown that although industrial emission makes up for most causes, sulfur dioxide from oil and coal combustion and nitrogen oxides produced from automobile engines have greatly intensified the problem. Electric power plants are also to blame for this issue.
One would tend to think that acid rain would greatly affect trees and plants, this based on the tree’s direct contact with the acid rain. An estimated sixty five percent of trees are effected by acid rain. The leaves of the trees are scarred by the rain, the seeds sterilized, and the immune system of entire forests are damaged, exposing them to disease infestation. The growth of forestlands can also be greatly slowed by the effects of acid rain. Lakes are also greatly affected by contaminated precipitation.
After being released into the atmosphere, sulfur dioxide settle on the land and come in contact with dew that is also known as acid rain. Acid rain affects many different ecosystems present on the Earth's surface. One of the greatly affected ecosystems is the forest and soil. Sulfuric acid is the cause of the damage to the trees. When it falls like rain it washes away the nutrients trees need to live on.
