Multiple choice economics environmental economics acid rain air pollution - effects and control air pollution and its effects

Which of the following causes regional pollution?

  1. Smog

  2. Acid rain
  3. $O _3$ layer depletion

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Smog is formed of smoke and fog and is particularly a pressing problem for large metropolitan cities. The constituents of smog are ground-level ozone, carbon monoxide, nitrogen oxides and volatile organic compounds. The sources of these pollutants are emissions from vehicles, smokestack emission paints etc. 
Acid rain is formed when sulphur dioxide and nitrogen oxides react with water and oxygen forming more acidic pollutant. Areas having industrial abundance are prone to acid rains. The major sources are coal-fired power plants, burning of fossil fuels etc.
Hence, the correct answer is 'Both A and B'

In acid rain, $SO _2$, sulphuric acid accounts for

  1. $100\%$
  2. $30\%$
  3. $50\%$
  4. $70\%$
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Acid rain is caused by a chemical reaction. Basically, rain that has unusually low pH is called acid rain. The most common chemicals that cause acid rain are sulphur oxides and nitric oxides. These substances rise high in the atmosphere where they react with water, oxygen and other chemicals to form more acidic pollutant. Sulphur dioxide on reaction with water and oxygen forms sulphur trioxide which is rapidly converted into sulphuric acid in presence of water. It accounts for 70% volume in acid rain.

Hence, the correct answer is '70%'.

Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen, and other chemicals to form more acidic pollutants.

A Correct answer
Explanation
Acid rain is caused by a chemical reaction that begins when compounds like sulfur dioxide and nitrogen oxides are released into the air. These substances can rise very high into the atmosphere, where they mix and react with water, oxygen and other chemicals to form more acidic pollutants, known as acid rain.
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 sulfur dioxide and nitrogen oxide, which react with the water molecules in the atmosphere to produce acids.

What is an estimated damage caused by acid rain to buildings in USA?

  1. 3 billion $ a Year
  2. 4 billion $ a Year
  3. 9 billion $ a Year
  4. 5 billion $ a Year
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Estimates regarding the economic impact of acid rain on buildings vary, but 5 billion dollars per year is a commonly cited figure in environmental science textbooks for the USA.

Acid rain is capable of damaging the buildings and historic monuments which are made up of rocks such as limestone and marble. Which among the following is the end product of such reaction?

  1. Quick Lime

  2. Calcium Carbonate

  3. Calcium Hydroxide

  4. Gypsum
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

When sulfuric acid in acid rain reacts with calcium carbonate (limestone/marble), it produces calcium sulfate, commonly known as gypsum, which is water-soluble and washes away.

Burning of coal produces oxides of sulphur and nitrogen which combined with water vapor leads to

  1. acid rain

  2. brackish water

  3. forest fire

  4. soil pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sulfur dioxide and nitrogen oxides emitted from burning coal react with atmospheric moisture to form sulfuric and nitric acids, resulting in acid rain.
