Conclusion

Acid rain is caused by burning coal and fossil fuels and industrial pollutants release sulfur dioxide and nitrogen in the atmosphere. These gases combine with hydrogen in the atmosphere in the form of water vapor. As they fall on the surface alters the chemical composition of soil and water affect food chains, destroying flowers and destroy forests.

 Sulphur dioxide and oxides of nitrogen are the main greenhouse gases by rain ácida.Estes oxidized in the atmosphere to form sulfuric and nitric acid. The oxidation occurs naturally in our environment. However, the emissions caused by human activity has been to equalize the levels of these gases.Na reality, humans have been exceeding the nature of this effect. Acid rain occurs when these emissions mix with sunlight and water and are then returned to Earth through rain or snow.
