What is Acid Rain? First identified in 1872 in Sweden and studied in the U.S. beginning in the 1950s‚ acid rain is precipitation in the form of rain‚ snow‚ hail‚ dew‚ or fog that transports sulfur and nitrogen compounds from the high atmosphere to the ground. Sulfur dioxide (SO2) and nitrogen oxides (NO‚ NO2) are bi-products from burning fuels in electric utilities and from other industrial and natural sources. These chemicals react with water‚ oxygen‚ carbon dioxide‚ and sunlight in the atmosphere

Cause and Effect on Acid Rain Introduction Beautifully crafted statues are now worn out or severely damaged‚ aquatic wildlife population are dying off‚ forests have lost the leaves that protect their trees and produce food‚ and the rates of lung diseases in humans are rising around the world. The cause of all of these problems can be linked back to acid rain. Most people don’t understand the concept or science behind acid rain. The common belief is that it’s a natural process‚ but it’s actually

ACID RAIN Cantarelli‚ Ilaria García Díaz‚ Bianca Gressier‚ Emilie Martínez Rivas‚ Carmen What’s the acid rain? Acid rain is a rain or any other form of precipitaton that is unusually acidic. What causes acid rain? Acid rain is caused by the burning of fossil fuels. Burning oil‚ gas and coal in power statons releases Sulphur Dioxide into the atmosphere. Burning oil and petrol in motor vehicles puts nitrogen oxides into the atmosphere. These gases mix with water droplets in the atmosphere creatng

Science one world essay – Acid Rain Acid rain has been an important global issue for centuries. Although most acid rain is caused by human activities‚ some acid rain occurs naturally. An example of natural acid rain is erupting volcanos‚ they give off smoke containing water vapor‚ carbon dioxide‚ sulphur dioxide and nitrogen compounds. The sulphur dioxide and nitrogen compounds cause small amounts of acid rain near the volcano. Pure water is not an acid‚ but even clean rainwater is slightly acidic

Acid Rain Within this past century‚ acidity of the air and acid rain have become recognized as one of the leading threats to our planet’s environment. No longer limited by geographic boundaries‚ acid causing emissions are causing problems all over the world. Some laws have been passed which limit the amount of pollutants that are released into the air‚ but tougher legislation must be implemented before this problem can be overcome. Acid rain is produced‚ when automobiles‚ smelters‚ power

Acid Rain Acid rain occurs when Sulphur Dioxide (SO2) is released into the atmosphere by electricity generation‚ motor vehicles‚ factories and by wildfires and volcanoes. Once released‚ the sulphur dioxide reacts with water to produce sulphuric acid. This has a pH of approximately 2-3 pH. This has a dramatic effect on water dwelling wildlife. Most water dwelling creatures can’t withstand water more acidic than pH 5. This causes the mass loss of life of animals such as trout‚ perch‚ frogs and mayflies

Acid-a chemical substance that neutralizes alkalis‚ dissolves some metals‚ and turns litmus red; typically‚ a corrosive or sour-tasting liquid of this kind. How does acid clean copper- “The oxygen in the air and the copper in the pennies form an oxide that coats the pennies and makes them look dirty. The acids break the copper oxide free from the penny. As we have seen experimentally‚ acid alone does not clean as well as acid and salt.” Can acid kill you?-”The actual causes of death however are not

Acid Rain Acid rain is polluted rain. The pollutants go up to the atmosphere and when it rains it brings the pollution down with it. Sulfur dioxide and nitrogen oxide are the gases that form the acid rain. When these gases mix with moisture it can make rain‚ snow‚ hail‚ or even fog. The scientific term for acid rain is acid deposition which means when the acid is taken from the air and is deposited on the earth. Major industries‚ coal burning factories‚ power plants and automoble engines
