A Correct answer
Explanation

Mineralization is the process by which nutrients are released from organic matter into a form usable by plants.

Multiple choice

What is the term for the process by which air pollutants are removed from the atmosphere?

  1. Deposition

  2. Diffusion

  3. Advection

  4. Volatilization
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 surfaces such as the ground, vegetation, and water bodies. This can occur through wet deposition (rain, snow, sleet, or fog) or dry deposition (direct contact with surfaces).

Multiple choice

What is the term for the process by which pollutants are removed from water through the use of plants?

  1. Bioremediation

  2. Phytoremediation

  3. Natural attenuation

  4. Self-purification
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Phytoremediation is the process by which pollutants are removed from water through the use of plants. Plants can absorb and accumulate pollutants from the water, helping to clean and restore contaminated water bodies.

Multiple choice

What is the term for the process by which air pollutants are converted into less harmful substances?

  1. Deposition

  2. Diffusion

  3. Advection

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

Transformation is the process by which air pollutants are converted into less harmful substances through chemical reactions in the atmosphere. This can occur through reactions with sunlight, oxygen, or other pollutants.

Multiple choice

What is the term for the process by which pollutants are removed from water through the use of microorganisms?

  1. Bioremediation

  2. Phytoremediation

  3. Natural attenuation

  4. Self-purification
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bioremediation is the process by which pollutants are removed from water through the use of microorganisms. Microorganisms can break down and degrade pollutants, converting them into less harmful substances.

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

Air purification, air filtration, and air scrubbing are all terms used to describe the process of removing pollutants from the air, improving air quality.

Multiple choice

What is the term used to describe the process of reducing the amount of pollutants released into the air?

  1. Pollution prevention

  2. Emission reduction

  3. Source control

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pollution prevention, emission reduction, and source control are all terms used to describe the process of reducing the amount of pollutants released into the air.

Multiple choice

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

Recycling involves the collection and processing of waste materials to convert them into usable materials.

Multiple choice

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

  1. Waste reduction

  2. Waste management

  3. Waste disposal

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

Waste reduction involves minimizing the amount of waste generated at the source.
