What is the term used to describe the process by which salt marshes trap and store carbon dioxide?
-
Carbon sequestration
-
Carbon fixation
-
Carbon cycling
-
Carbon release
A
Correct answer
Explanation

What is the term used to describe the process of breaking down textile waste into its constituent materials, which can then be used to create new products?
-
Recycling
-
Upcycling
-
Downcycling
-
Composting
A
Correct answer
Explanation
Recycling in the context of textiles involves breaking down textile waste into its constituent materials, such as fibers, which can then be used to create new products. This process helps to reduce the amount of waste sent to landfills and promotes the circularity of materials in the fashion industry.

-
Carbon Sequestration
-
Carbon Offsetting
A
Correct answer
Explanation
Carbon Capture and Storage (CCS) refers to the process of capturing carbon dioxide from industrial sources and storing it underground or in geological formations.
What is the term used to describe the process of capturing and storing carbon dioxide from the atmosphere?
-

Bioremediation is a process that uses microorganisms to:
-
Clean up contaminated environments
-
Produce biofuels
-
Create new drugs
-
Generate electricity
A
Correct answer
Explanation
Bioremediation is a process that uses microorganisms, such as bacteria and fungi, to break down and remove contaminants from the environment.
In situ bioremediation is a process that:
-
Treats contaminants in place
-
Requires the excavation of contaminated soil
-
Uses microorganisms to break down contaminants
-
All of the above
A
Correct answer
Explanation
In situ bioremediation treats contaminants in place, without the need to excavate the contaminated soil.
Ex situ bioremediation is a process that:
-
Treats contaminants in place
-
Requires the excavation of contaminated soil
-
Uses microorganisms to break down contaminants
-
All of the above
B
Correct answer
Explanation
Ex situ bioremediation requires the excavation of contaminated soil, which is then treated in a controlled environment.
