  1. Soil remediation

  2. Soil restoration

  3. Soil reclamation

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

Soil remediation refers to the process of treating and cleaning up contaminated soil to reduce or eliminate its harmful effects on human health and the environment.

Multiple choice

What is the term used to describe the process of capturing and storing carbon dioxide to prevent its release into the atmosphere?

  1. Carbon sequestration

  2. Carbon capture and storage (CCS)

  3. Mitigation

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

Carbon capture and storage (CCS) involves capturing carbon dioxide from industrial processes or the atmosphere and storing it underground to reduce greenhouse gas emissions.

Multiple choice

What is the term used to describe the process by which forests absorb carbon dioxide from the atmosphere?

  1. Photosynthesis

  2. Respiration

  3. Transpiration

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

Photosynthesis is the process by which plants, including trees, absorb carbon dioxide from the atmosphere and convert it into glucose and oxygen.

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. Dilution

  4. Advection
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 Earth's surface. This can occur through wet deposition (rain or snow) or dry deposition (settling of particles).

Multiple choice

What is the name of the process by which plants absorb and break down contaminants in the soil?

  1. Phytoremediation

  2. Bioremediation

  3. In situ treatment

  4. Excavation and disposal
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Phytoremediation is the process by which plants absorb and break down contaminants in the soil. It is a natural and cost-effective way to clean up contaminated soil.

Multiple choice

  1. Bioremediation

  2. Phytoremediation

  3. In situ treatment

  4. Excavation and disposal
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bioremediation is the process by which bacteria and other microorganisms break down contaminants in the soil. It is a natural and cost-effective way to clean up contaminated soil.

Multiple choice

What is the name of the process by which contaminated soil is excavated and disposed of?

  1. Excavation and disposal

  2. In situ treatment

  3. Phytoremediation

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

Excavation and disposal is the process by which contaminated soil is excavated and disposed of. It is a common method for cleaning up contaminated soil.

Multiple choice

  1. Natural attenuation

  2. Bioremediation

  3. Phytoremediation

  4. In situ treatment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Natural attenuation is the process by which contaminants are broken down or removed from the soil by natural processes, such as biodegradation, volatilization, and adsorption.

Multiple choice

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

  1. Zero waste

  2. Waste minimization

  3. Waste recycling

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

Zero waste refers to the goal of eliminating waste production by designing products and systems that can be reused, recycled, or composted. It involves reducing consumption, reusing materials, and recycling or composting waste to minimize the amount of waste sent to landfills or incinerators.
