What is the primary cause of acid rain?

  1. Volcanic eruptions

  2. Forest fires

  3. Burning of fossil fuels

  4. Natural weathering of rocks


Correct Option: C
Explanation:

The burning of fossil fuels, such as coal and oil, releases sulfur dioxide and nitrogen oxides into the atmosphere, which react with water vapor to form sulfuric and nitric acids.

Which of the following is NOT a common pollutant that contributes to acid rain?

  1. Carbon monoxide

  2. Sulfur dioxide

  3. Nitrogen oxides

  4. Hydrocarbons


Correct Option: D
Explanation:

Hydrocarbons are not directly related to acid rain formation. They are primarily associated with photochemical smog and ozone depletion.

What is the term used to describe the process by which acids are removed from the atmosphere?

  1. Acidification

  2. Neutralization

  3. Deposition

  4. Precipitation


Correct Option: C
Explanation:

Deposition refers to the process by which acids are removed from the atmosphere through wet deposition (rain, snow, fog) or dry deposition (dust, particles).

Which of the following is NOT an effect of acid rain on aquatic ecosystems?

  1. Increased acidity of water bodies

  2. Reduced fish populations

  3. Enhanced growth of aquatic plants

  4. Damage to fish gills and eggs


Correct Option: C
Explanation:

Acid rain typically has negative effects on aquatic ecosystems, including decreased pH levels, reduced fish populations, and damage to fish gills and eggs. It does not promote the growth of aquatic plants.

What is the term used to describe the phenomenon where trees are damaged or killed due to acid rain?

  1. Acidification

  2. Deforestation

  3. Forest decline

  4. Tree mortality


Correct Option: C
Explanation:

Forest decline refers to the weakening and death of trees due to various factors, including acid rain. Acid rain can damage tree leaves, inhibit nutrient uptake, and make trees more susceptible to pests and diseases.

Which of the following is NOT a potential solution to reduce acid rain?

  1. Switching to renewable energy sources

  2. Using low-sulfur fuels

  3. Installing emission control devices

  4. Increasing the burning of fossil fuels


Correct Option: D
Explanation:

Increasing the burning of fossil fuels would exacerbate acid rain by releasing more sulfur dioxide and nitrogen oxides into the atmosphere.

What is the primary role of limestone in mitigating the effects of acid rain?

  1. Neutralizing acids in the atmosphere

  2. Absorbing sulfur dioxide from power plant emissions

  3. Reducing nitrogen oxide emissions from vehicles

  4. Promoting the growth of acid-resistant plants


Correct Option: A
Explanation:

Limestone, when crushed and spread on land or added to water bodies, can help neutralize acids and reduce the acidity of the environment.

Which country is known for its extensive use of limestone to combat acid rain?

  1. United States

  2. China

  3. Germany

  4. Sweden


Correct Option: D
Explanation:

Sweden has been a pioneer in using limestone to neutralize acid rain. The country has implemented large-scale liming programs to reduce the acidity of its lakes and forests.

What is the term used to describe the process of converting sulfur dioxide into sulfuric acid in the atmosphere?

  1. Oxidation

  2. Reduction

  3. Hydrolysis

  4. Neutralization


Correct Option: A
Explanation:

Oxidation is the process by which sulfur dioxide reacts with oxygen in the presence of sunlight to form sulfuric acid.

Which of the following is NOT a potential consequence of acid rain on human health?

  1. Respiratory problems

  2. Cardiovascular issues

  3. Increased risk of cancer

  4. Improved air quality


Correct Option: D
Explanation:

Acid rain does not directly improve air quality. It can contribute to air pollution by releasing harmful pollutants into the atmosphere.

What is the term used to describe the process of reducing the acidity of a substance?

  1. Acidification

  2. Alkalization

  3. Neutralization

  4. Deposition


Correct Option: B
Explanation:

Alkalization refers to the process of making a substance less acidic by adding a base or alkaline substance.

Which of the following is NOT a potential impact of acid rain on buildings and structures?

  1. Corrosion of metal surfaces

  2. Erosion of stone facades

  3. Increased durability of concrete structures

  4. Damage to paint and coatings


Correct Option: C
Explanation:

Acid rain can have detrimental effects on buildings and structures, such as corrosion of metal surfaces, erosion of stone facades, and damage to paint and coatings. It does not increase the durability of concrete structures.

What is the term used to describe the process of removing pollutants from the air?

  1. Deposition

  2. Neutralization

  3. Air pollution control

  4. Oxidation


Correct Option: C
Explanation:

Air pollution control refers to the various technologies and strategies used to reduce or eliminate air pollutants from industrial emissions, vehicle exhaust, and other sources.

Which of the following is NOT a common method for reducing sulfur dioxide emissions from power plants?

  1. Flue gas desulfurization

  2. Limestone injection

  3. Selective catalytic reduction

  4. Increasing the burning of coal


Correct Option: D
Explanation:

Increasing the burning of coal would increase sulfur dioxide emissions. Flue gas desulfurization, limestone injection, and selective catalytic reduction are all technologies used to reduce sulfur dioxide emissions from power plants.

What is the primary goal of the Clean Air Act in the United States regarding acid rain?

  1. Reducing greenhouse gas emissions

  2. Improving air quality in urban areas

  3. Controlling acid rain and its effects

  4. Promoting the use of renewable energy sources


Correct Option: C
Explanation:

The Clean Air Act includes provisions specifically aimed at reducing acid rain by regulating sulfur dioxide and nitrogen oxide emissions from power plants and other sources.
