Which pollutant is primarily responsible for acid rain?

  1. Carbon Monoxide

  2. Sulfur Dioxide

  3. Nitrogen Dioxide

  4. Ozone


Correct Option: B
Explanation:

Sulfur dioxide (SO2) is a major contributor to acid rain, which occurs when sulfur oxides and nitrogen oxides react with water vapor in the atmosphere.

How does air pollution affect crop growth and yield?

  1. Enhances photosynthesis and growth

  2. Causes stunted growth and reduced yield

  3. Improves soil fertility

  4. Increases water retention in plants


Correct Option: B
Explanation:

Air pollution, particularly ozone and sulfur dioxide, can damage plant tissues, leading to stunted growth, reduced leaf area, and decreased crop yield.

Which air pollutant is a major contributor to ground-level ozone formation?

  1. Carbon Monoxide

  2. Nitrogen Oxides

  3. Particulate Matter

  4. Volatile Organic Compounds


Correct Option: D
Explanation:

Volatile organic compounds (VOCs) react with nitrogen oxides in the presence of sunlight to form ground-level ozone, a harmful air pollutant.

How does air pollution impact soil quality and fertility?

  1. Enriches soil with essential nutrients

  2. Increases soil pH and alkalinity

  3. Degrades soil structure and nutrient content

  4. Enhances soil moisture retention


Correct Option: C
Explanation:

Air pollution can lead to soil acidification, nutrient leaching, and the accumulation of toxic substances, which can harm soil microorganisms and reduce soil fertility.

Which air pollutant is primarily responsible for the formation of smog?

  1. Carbon Monoxide

  2. Nitrogen Dioxide

  3. Particulate Matter

  4. Ozone


Correct Option: D
Explanation:

Smog is a type of air pollution characterized by high levels of ozone and other pollutants, primarily formed by the reaction of nitrogen oxides and volatile organic compounds in the presence of sunlight.

How does air pollution affect the nutritional value of crops?

  1. Enhances vitamin and mineral content

  2. Reduces protein and carbohydrate levels

  3. Improves crop flavor and aroma

  4. Increases water content and juiciness


Correct Option: B
Explanation:

Air pollution can reduce the protein and carbohydrate content of crops, as well as alter their vitamin and mineral composition.

Which air pollutant is a major contributor to respiratory problems in agricultural workers?

  1. Carbon Monoxide

  2. Nitrogen Dioxide

  3. Particulate Matter

  4. Sulfur Dioxide


Correct Option: C
Explanation:

Particulate matter, especially fine and ultrafine particles, can penetrate deep into the lungs and cause respiratory issues, particularly among agricultural workers exposed to crop dust and other airborne pollutants.

How does air pollution impact the biodiversity of agricultural ecosystems?

  1. Enhances species diversity and richness

  2. Reduces habitat fragmentation and isolation

  3. Promotes beneficial insect populations

  4. Increases soil microbial activity


Correct Option: B
Explanation:

Air pollution can contribute to habitat fragmentation and isolation, disrupting ecological interactions and reducing biodiversity in agricultural landscapes.

Which air pollutant is primarily responsible for the greenhouse effect and global warming?

  1. Carbon Dioxide

  2. Methane

  3. Nitrous Oxide

  4. Sulfur Hexafluoride


Correct Option: A
Explanation:

Carbon dioxide (CO2) is the primary greenhouse gas responsible for trapping heat in the atmosphere, leading to global warming and climate change.

How does air pollution affect the quality and safety of agricultural products?

  1. Improves food taste and texture

  2. Enhances nutritional value and shelf life

  3. Reduces the risk of foodborne illnesses

  4. Increases the presence of contaminants and toxins


Correct Option: D
Explanation:

Air pollution can lead to the accumulation of contaminants and toxins in agricultural products, such as heavy metals, pesticides, and other pollutants, posing potential health risks to consumers.

Which air pollutant is a major contributor to the formation of acid fog?

  1. Carbon Monoxide

  2. Nitrogen Oxides

  3. Sulfur Dioxide

  4. Ozone


Correct Option: C
Explanation:

Sulfur dioxide (SO2) is a major precursor to acid fog, which forms when sulfur oxides react with water vapor in the atmosphere.

How does air pollution impact the water quality of agricultural watersheds?

  1. Enhances water clarity and purity

  2. Reduces nutrient runoff and eutrophication

  3. Improves aquatic habitat and biodiversity

  4. Increases the presence of pollutants and contaminants


Correct Option: D
Explanation:

Air pollution can contribute to the deposition of pollutants and contaminants into water bodies, affecting water quality and potentially harming aquatic ecosystems.

Which air pollutant is primarily responsible for the formation of photochemical smog?

  1. Carbon Monoxide

  2. Nitrogen Oxides

  3. Particulate Matter

  4. Volatile Organic Compounds


Correct Option: D
Explanation:

Volatile organic compounds (VOCs) react with nitrogen oxides in the presence of sunlight to form photochemical smog, a type of air pollution characterized by high levels of ozone and other pollutants.

How does air pollution affect the economic viability of agricultural operations?

  1. Enhances crop yields and profitability

  2. Reduces production costs and inputs

  3. Improves market value and demand for agricultural products

  4. Increases the risk of crop losses and financial instability


Correct Option: D
Explanation:

Air pollution can lead to crop losses, reduced yields, and increased production costs, impacting the economic viability and stability of agricultural operations.

Which air pollutant is a major contributor to the formation of urban heat islands?

  1. Carbon Monoxide

  2. Nitrogen Oxides

  3. Particulate Matter

  4. Volatile Organic Compounds


Correct Option: C
Explanation:

Particulate matter, especially black carbon, can absorb and trap heat, contributing to the formation of urban heat islands, where temperatures are significantly higher than surrounding rural areas.
