Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Vehicular emissions, industrial emissions, and burning of fossil fuels can all contribute to air pollution in India.

Multiple choice

Which of the following human activities is a major contributor to ozone depletion?

  1. Burning fossil fuels

  2. Planting trees

  3. Recycling materials

  4. Using public transportation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Burning fossil fuels, such as coal, oil, and natural gas, releases various pollutants, including ozone-depleting substances, into the atmosphere. These substances contribute significantly to ozone depletion.

Multiple choice

Which of the following is a major cause of air pollution?

  1. Deforestation

  2. Burning fossil fuels

  3. Overpopulation

  4. Natural disasters
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Burning fossil fuels, such as coal, oil, and natural gas, releases harmful pollutants into the air, including particulate matter, sulfur dioxide, and nitrogen oxides.

Multiple choice

Which pollutant is commonly associated with vehicle emissions?

  1. Carbon monoxide

  2. Sulfur dioxide

  3. Nitrogen dioxide

  4. Particulate matter
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon monoxide is a colorless, odorless gas that is produced by the incomplete combustion of fuels, such as those used in vehicles.

Multiple choice

Which of the following is a major source of air pollution in urban areas?

  1. Industrial emissions

  2. Vehicle emissions

  3. Construction activities

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

Vehicle emissions are a major source of air pollution in urban areas, particularly due to the high concentration of vehicles and the release of pollutants such as carbon monoxide, nitrogen dioxide, and particulate matter.

Multiple choice

What is the term used to describe the maximum concentration of a pollutant in the air that is considered safe for human health?

  1. Air quality standard

  2. Emission limit

  3. Ambient air quality guideline

  4. Threshold limit value
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Air quality standards are established by regulatory agencies to define the maximum concentration of a pollutant in the air that is considered safe for human health.

Multiple choice

Which pollutant is primarily responsible for acid rain?

  1. Sulfur dioxide

  2. Nitrogen dioxide

  3. Carbon monoxide

  4. Particulate matter
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sulfur dioxide is a major contributor to acid rain, as it reacts with water vapor in the atmosphere to form sulfuric acid.

Multiple choice

Which of the following is an example of a primary air pollutant?

  1. Ozone

  2. Carbon monoxide

  3. Nitrogen dioxide

  4. Particulate matter
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Primary air pollutants are emitted directly into the atmosphere from sources such as vehicles, industries, and power plants. Carbon monoxide is a primary air pollutant.
