  1. Primary pollutant

  2. Secondary pollutant

  3. Criteria pollutant

  4. Hazardous pollutant
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Criteria pollutants are a type of air pollutant regulated by the Clean Air Act, but they are not a type of air pollutant in general.

  1. Carbon monoxide

  2. Particulate matter

  3. Nitrogen dioxide

  4. Sulfur dioxide
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon monoxide is the term for the gas that is produced by incomplete combustion and is a major component of vehicle exhaust.

Multiple choice

Which of the following is NOT a type of air pollution?

  1. Smog

  2. Acid rain

  3. Eutrophication

  4. Ozone depletion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Eutrophication is a type of water pollution, not air pollution.

Multiple choice

Which of the following is NOT a strategy for reducing air pollution from ships?

  1. Using cleaner fuels

  2. Installing scrubbers

  3. Reducing speed

  4. Increasing cargo weight
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Increasing cargo weight is not a strategy for reducing air pollution from ships. In fact, it can actually lead to increased emissions, as ships need to burn more fuel to move the heavier load.

Multiple choice

What is the main cause of air pollution in urban areas?

  1. Industrial emissions

  2. Vehicle emissions

  3. Power plants

  4. Residential heating
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vehicle emissions are the main cause of air pollution in urban areas. Cars, trucks, and buses release a variety of pollutants into the air, including nitrogen oxides, carbon monoxide, and particulate matter.

Multiple choice

What is the main cause of air pollution in rural areas?

  1. Industrial emissions

  2. Vehicle emissions

  3. Power plants

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

Agricultural activities are the main cause of air pollution in rural areas. These activities can release a variety of pollutants into the air, including ammonia, nitrogen oxides, and particulate matter.

Multiple choice

What is the main cause of air pollution in developing countries?

  1. Industrial emissions

  2. Vehicle emissions

  3. Power plants

  4. Cooking and heating with biomass fuels
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Cooking and heating with biomass fuels (such as wood, charcoal, and dung) is the main cause of air pollution in developing countries. These fuels release a variety of pollutants into the air, including particulate matter, carbon monoxide, and nitrogen oxides.
