What is the term used to describe the process by which organic matter from the water column settles to the bottom and becomes available to benthic organisms?
-
Pelagic sedimentation
-
Nektonic sedimentation
-
Benthic sedimentation
-
Planktonic sedimentation
C
Correct answer
Explanation
Benthic sedimentation is the process by which organic matter from the water column settles to the bottom and becomes available to benthic organisms.
What is the term used to describe the process by which benthic organisms recycle nutrients and contribute to the overall productivity of an ecosystem?
-
Pelagic nutrient cycling
-
Nektonic nutrient cycling
-
Benthic nutrient cycling
-
Planktonic nutrient cycling
C
Correct answer
Explanation
Benthic nutrient cycling is the process by which benthic organisms recycle nutrients and contribute to the overall productivity of an ecosystem.
What is the term used to describe the process of extracting bioactive compounds from marine organisms?
-
Bioprospecting
-
Bioremediation
-
Biodegradation
-
Bioaccumulation
A
Correct answer
Explanation
Bioprospecting refers to the exploration and extraction of bioactive compounds from marine organisms for potential use in pharmaceuticals, cosmetics, and other industries.
What is the term used to describe the process of capturing and storing atmospheric carbon dioxide?
-
Carbon sequestration
-
Carbon capture and storage
-
Carbon offsetting
-
Carbon footprint
A
Correct answer
Explanation
Carbon sequestration refers to the process of capturing and storing atmospheric carbon dioxide in various forms, including in plants, soil, and geological formations.
What is the term used to describe the process by which oil breaks down in the environment?
-
Biodegradation
-
Photodegradation
-
Evaporation
-
Dispersion
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.
What is the term used to describe the process by which air pollutants are removed from the atmosphere?
-
Deposition
-
Dispersion
-
Evaporation
-
Photolysis
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).
What is the term used to describe the process by which air pollutants are transformed into new compounds in the atmosphere?
-
Deposition
-
Dispersion
-
Evaporation
-
Chemical reactions
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.
What is the term used to describe the process of removing carbon dioxide from the atmosphere?
-
Carbon capture and storage
-
Carbon sequestration
-
Carbon offsetting
-
Carbon pricing
A
Correct answer
Explanation
Carbon capture and storage (CCS) is the process of removing carbon dioxide from the atmosphere and storing it underground.
What is the term used to describe the process of reducing the amount of waste produced?
-
Recycling.
-
Composting.
-
Landfilling.
-
Incineration.
A
Correct answer
Explanation
Recycling involves converting waste materials into new materials and objects, reducing the need for raw materials and minimizing waste disposal.
What is the term used to describe the process of reducing the amount of chemicals used in agriculture?
-
Organic farming.
-
Conventional farming.
-
Sustainable agriculture.
-
Genetically modified crops.
A
Correct answer
Explanation
Organic farming involves reducing or eliminating the use of synthetic chemicals, such as pesticides and fertilizers, in agricultural practices.
What is the term used to describe the process of reducing the amount of solid waste produced?
-
Waste reduction.
-
Recycling.
-
Composting.
-
Landfilling.
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.
What is the term used to describe the process of removing radioactive contamination from a site?
-
Decontamination
-
Remediation
-
Restoration
-
Reclamation
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.
What is the term used to describe the process of converting radioactive waste into a stable and inert form?
-
Immobilization
-
Vitrification
-
Encapsulation
-
Calcination
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.
