Explain acid rain and its effects.

Acid rain is caused when the oxides of nitrogen and sulphur are precipitated from the rain water. These oxides are present in the upper atmosphere and when rain falls these oxides get dissolved in rain water and forms nitric acid and sulfuric acid thus makes it acidic.Acid rain usually has a pH of less than 5.6.

Acid rain falls on buildings, cars, and trees and can make lakes acidic.Effect of acid rain on ecosystem is as follow:

1. Damage to animals : Most of the aquatic animals die off due to rising acidity levels in water bodies due to acid rain.

2. Material damage: It causes damage to many objects including building, historical monuments, statues and cars. The chemicals found in acid rain can cause paint to peel and stone statues to begin to look old which reduces their value and beauty. For example, the monument Taj Mahal is being slowly eaten away and the marble is getting discolored and lusterless due to acid rain effect.

3. Damage to plants and trees: Acidic water is dangerous to plants. Acid rain that seeps into ground can dissolve plants and trees nutrients that need trees and plants to be healthy which hurts their ability to survive. As a result, agricultural productivity and vegetation are also decreased.

In all over globe acid rain is heavily there in :
1. eastern Europe from Poland northward into Scandinavia,
2. the eastern third of the United States,
3. southeastern Canada
4. the southeastern coast of China and Taiwan.

Acid rain is a rain or any other form of precipitation that is unusually acidic, meaning that it possesses elevated levels of hydrogen ions (low pH). It can have harmful effects on plants, aquatic animals, and infrastructure. Acid rain is caused by emissions of carbon dioxidesulfur dioxide and nitrogen oxideswhich react with the water molecules in the atmosphere to produce acids. Governments have made efforts since the 1970s to reduce the release of sulfur dioxide into theatmosphere with positive results. Nitrogen oxides can also be produced naturally by lightning strikes and sulfur dioxide is produced by volcanic eruptions. The chemicals in acid rain can cause paint to peel, corrosion of steel structures such as bridges, and erosion of stone statues.

Acid rain causes acidification of lakes and streams and contributes to the damage of trees at high elevations (for example, red spruce trees above 2,000 feet) and many sensitive forest soils. In addition, acid rain accelerates the decay of building materials and paints, including irreplaceable buildings, statues, and sculptures that are part of our nation's cultural heritage. Prior to falling to the earth, sulfur dioxide (SO2) and nitrogen oxide (NOx) gases and their particulate matter derivatives—sulfates and nitrates—contribute to visibility degradation and harm public health.

Acid rain is a result of air pollution. When any type of fuel is burnt, lots of different chemicals are produced. The smoke that comes from a fire or the fumes that come out of a car exhaust don't just contain the sooty Grey particles that you can see - they also contains lots of invisible gases that can be even more harmful to our environment.

Power stations, factories and cars all burn fuels and therefore they all produce polluting gases. Some of these gases (especially nitrogen oxides and sulphur dioxide) react with the tiny droplets of water in clouds to form sulphuric and nitric acids. The rain from these clouds then falls as very weak acid - which is why it is known as "acid rain".

The smoke released by factoies especially  sulphu dioxide & nitrogen oxide wwhich when in contact with rain water causes acid rain.The effects of acid rain is 1]it damages the buildings

                                                        2]it damages the monuments

                                                         3]it damages the natural vegetation

                                                         4]it damages the natural habitats of living organisms

                                                         5] it damages the crops.

the factories releases poisnous gases such as sulphuroxide and nitrogen oxide when they get mixed with air they contaminates the air  and when it rains the pollutants also rains it has caused a massive dammage .THE TAJ MAHAL surface is getting yellowish. the process is called ACID RAIN

 when a fossil fuel burns it releases sulphur dioxide  n nitogen oxide which goes in the atmosphere and dissolve with water vapour present in the air to form sulphuric acid and nitric  acid. these acids then drop down with rain making the rain acidic.  this is called acid rain.

effects-

  1. it corrodes the buildings or monuments.
  2. it disturbs the aquatic life
  3. it causes skin diseases
  4. it effects the crops and forests

 the gasses like sulphur dioxide and nitrogen dioxide combine with water vapours to form acid .when rain falls the acid comes down with rain. it corrodes the object, it causes skin diseases.
