Correct answer
Explanation

Weathering is the term used to describe the process by which oil becomes weathered and broken down in the marine environment. It includes processes such as evaporation, photooxidation, biodegradation, and dispersion.

Multiple choice

What is the term used to describe the process by which oil droplets become smaller and dispersed in the water column?

  1. Emulsification

  2. Dispersion

  3. Photooxidation

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

Dispersion is the term used to describe the process by which oil droplets become smaller and dispersed in the water column. This can occur naturally through wave action and turbulence, or it can be enhanced through the use of chemical dispersants.

Multiple choice

What is the term used to describe the process by which oil is broken down by microorganisms?

  1. Biodegradation

  2. Photooxidation

  3. Evaporation

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

Biodegradation is the term used to describe the process by which oil is broken down by microorganisms. This process can occur naturally in the marine environment, but it can be enhanced through the use of bioremediation techniques.

Multiple choice

What is the term used to describe the process by which oil is removed from the marine environment through evaporation?

  1. Biodegradation

  2. Photooxidation

  3. Evaporation

  4. Dispersion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Evaporation is the term used to describe the process by which oil is removed from the marine environment through evaporation. This process occurs when oil droplets become smaller and lighter, allowing them to rise to the surface of the water and evaporate into the atmosphere.
