  1. Carbon capture and storage (CCS)

  2. Carbon capture and utilization (CCU)

  3. Carbon dioxide removal (CDR)

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

Carbon capture and storage (CCS) refers to the process of capturing CO2 from industrial sources, such as power plants, and storing it underground or in geological formations to prevent its release into the atmosphere.

  1. Photochemical smog

  2. Acid rain

  3. Eutrophication

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

Photochemical smog is the term used to describe the process of VOCs reacting with sunlight to form smog.

Multiple choice

  1. Air purification

  2. Dehumidification

  3. Ventilation

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

Air purification, dehumidification, and ventilation are all methods used to remove VOCs from the air.

Multiple choice

What is the term used to describe the process of VOCs condensing into liquid droplets in the atmosphere?

  1. Condensation

  2. Evaporation

  3. Sublimation

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

Condensation is the term used to describe the process of VOCs condensing into liquid droplets in the atmosphere.

Multiple choice

What is the term for the process by which microplastics are ingested by marine organisms?

  1. Microplastic Ingestion

  2. Plastic Consumption

  3. Polymer Accumulation

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

Microplastic ingestion refers to the process by which marine organisms consume microplastics, either directly from the water or indirectly through their prey. Microplastics can accumulate in the digestive tracts of marine animals, causing physical damage, reducing nutrient absorption, and potentially leaching toxic chemicals into their bodies.

Multiple choice

What is the term for the process by which marine debris accumulates in the oceans?

  1. Ocean Dumping

  2. Marine Pollution

  3. Plastic Accumulation

  4. Ocean Garbage Patch Formation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Ocean dumping refers to the intentional disposal of waste materials into the oceans. This includes the dumping of sewage, industrial waste, and other hazardous substances. Ocean dumping is a major source of marine pollution and contributes to the accumulation of debris in the oceans, posing risks to marine life and ecosystems.

Multiple choice

What is the term for the process by which marine organisms become entangled in plastic debris?

  1. Plastic Entanglement

  2. Marine Debris Entanglement

  3. Bycatch

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

Plastic entanglement refers to the process by which marine organisms become trapped or entangled in plastic debris. This can occur when animals mistake plastic items for food or shelter, or when they become caught in discarded fishing gear. Plastic entanglement can cause injury, starvation, or death to marine organisms, and can also have negative impacts on their populations and ecosystems.

Multiple choice

What is the term used to describe the process by which nitrogen dioxide (NO2) is converted into nitrate (NO3-) in the atmosphere?

  1. Nitrification

  2. Denitrification

  3. Assimilation

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

Nitrification is the process by which NO2 is oxidized to form nitrate (NO3-) in the atmosphere.

Multiple choice

What is the term used to describe the process by which nitrogen dioxide (NO2) is converted into nitrogen monoxide (NO) in the atmosphere?

  1. Nitrification

  2. Denitrification

  3. Assimilation

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

Reduction is the process by which NO2 is converted into NO in the atmosphere.

Multiple choice

What is the primary mechanism by which plants accumulate heavy metals from the soil?

  1. Active transport

  2. Passive transport

  3. Chelation

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

Plants primarily accumulate heavy metals through passive transport, where metals enter the plant's roots along with water and nutrients.

Multiple choice

What is the process by which microorganisms convert toxic heavy metals into less harmful forms?

  1. Bioaccumulation

  2. Biotransformation

  3. Biodegradation

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

Biotransformation is the process by which microorganisms convert toxic heavy metals into less harmful forms through enzymatic reactions.

Multiple choice

Which of the following is NOT a common technique used in bioremediation of heavy metals?

  1. Phytoremediation

  2. Bioaugmentation

  3. Biosorption

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

Bioventing is a technique used to remediate volatile organic compounds, not heavy metals.

Multiple choice

What is the term used to describe the ability of certain plants to accumulate and tolerate high levels of heavy metals?

  1. Hyperaccumulation

  2. Phytoextraction

  3. Phytoremediation

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

Hyperaccumulation is the ability of certain plants to accumulate and tolerate high levels of heavy metals in their tissues.
