  1. Biodegradation

  2. Photodegradation

  3. Evaporation

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

Biodegradation is the process by which oil is broken down by microorganisms in the environment. This is a natural process that can take several months or years to complete.

Multiple choice

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

  1. Deposition

  2. Dispersion

  3. Evaporation

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

Deposition is the process by which air pollutants are removed from the atmosphere and deposited on the ground or water. This can occur through wet deposition (rain or snow) or dry deposition (settling of particles).

Multiple choice

What is the term used to describe the process by which air pollutants are transformed into new compounds in the atmosphere?

  1. Deposition

  2. Dispersion

  3. Evaporation

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

Chemical reactions are the process by which air pollutants are transformed into new compounds in the atmosphere. These reactions can occur between pollutants themselves or between pollutants and other compounds in the air.

Multiple choice

What is the term used to describe the process of removing carbon dioxide from the atmosphere?

  1. Carbon capture and storage

  2. Carbon sequestration

  3. Carbon offsetting

  4. Carbon pricing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon capture and storage (CCS) is the process of removing carbon dioxide from the atmosphere and storing it underground.

Multiple choice

What is the term used to describe the process of reducing the amount of waste produced?

  1. Recycling.

  2. Composting.

  3. Landfilling.

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

Recycling involves converting waste materials into new materials and objects, reducing the need for raw materials and minimizing waste disposal.

Multiple choice

  1. Organic farming.

  2. Conventional farming.

  3. Sustainable agriculture.

  4. Genetically modified crops.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Organic farming involves reducing or eliminating the use of synthetic chemicals, such as pesticides and fertilizers, in agricultural practices.

Multiple choice

What is the term used to describe the process of reducing the amount of solid waste produced?

  1. Waste reduction.

  2. Recycling.

  3. Composting.

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

Waste reduction involves reducing the amount of waste generated at the source, such as by using reusable products, buying less packaging, and avoiding single-use items.

Multiple choice

Which of the following is NOT a commonly used method for sampling gaseous air pollutants?

  1. Grab sampling

  2. Continuous monitoring

  3. Passive sampling

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

Chromatography is a laboratory technique used to separate and analyze chemical compounds in a sample. It is not commonly used for sampling air pollutants in the field.

Multiple choice

  1. Gravimetric analysis

  2. Nephelometry

  3. Gas chromatography

  4. Beta attenuation
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Gas chromatography is a laboratory technique used to separate and analyze chemical compounds in a sample. It is not commonly used for sampling particulate matter in air.

Multiple choice

What is the term used to describe the process of removing radioactive contamination from a site?

  1. Decontamination

  2. Remediation

  3. Restoration

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

Decontamination is the term used to describe the process of removing radioactive contamination from a site, which involves removing or reducing the levels of radioactive materials present.

Multiple choice

What is the term used to describe the process of converting radioactive waste into a stable and inert form?

  1. Immobilization

  2. Vitrification

  3. Encapsulation

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

Immobilization is the term used to describe the process of converting radioactive waste into a stable and inert form, which involves trapping the radioactive materials in a solid matrix to prevent their release into the environment.
