Which of the following marine organisms is most vulnerable to oil pollution?

  1. Sea turtles

  2. Fish

  3. Seabirds

  4. Coral reefs


Correct Option: C
Explanation:

Seabirds, particularly those that feed on the surface of the water, are highly susceptible to oil pollution as they can ingest oil or become coated in it, leading to impaired waterproofing, reduced buoyancy, and potential death.

How does oil pollution affect the ability of marine mammals to hunt and feed?

  1. It reduces their visibility, making it harder to find prey.

  2. It damages their sense of smell, making it harder to locate food.

  3. It coats their fur, reducing their insulation and making them more susceptible to cold.

  4. All of the above.


Correct Option: D
Explanation:

Oil pollution can impair marine mammals' ability to hunt and feed by reducing their visibility, damaging their sense of smell, and coating their fur, leading to reduced insulation and increased susceptibility to cold.

Which component of crude oil is particularly toxic to marine life?

  1. Benzene

  2. Toluene

  3. Polycyclic aromatic hydrocarbons (PAHs)

  4. All of the above


Correct Option: C
Explanation:

Polycyclic aromatic hydrocarbons (PAHs) are a group of compounds found in crude oil that are highly toxic to marine life. They can cause a range of adverse effects, including cancer, reproductive problems, and developmental abnormalities.

How does oil pollution impact the food chain in marine ecosystems?

  1. It reduces the availability of food for organisms at higher trophic levels.

  2. It can bioaccumulate and magnify as it moves up the food chain.

  3. It disrupts the balance between predators and prey.

  4. All of the above.


Correct Option: D
Explanation:

Oil pollution can impact the food chain in marine ecosystems by reducing the availability of food for organisms at higher trophic levels, bioaccumulating and magnifying as it moves up the food chain, and disrupting the balance between predators and prey.

Which of the following human health risks is associated with exposure to oil pollution?

  1. Respiratory problems

  2. Skin irritation

  3. Cancer

  4. All of the above


Correct Option:
Explanation:

Exposure to oil pollution can lead to a range of human health risks, including respiratory problems, skin irritation, and cancer. Inhalation of oil vapors can cause respiratory irritation, while skin contact with oil can lead to dermatitis and other skin conditions. Long-term exposure to certain components of oil, such as PAHs, has been linked to an increased risk of cancer.

What is the primary method used to clean up oil spills in marine environments?

  1. Dispersants

  2. Booms and skimmers

  3. Sorbents

  4. In-situ burning


Correct Option: B
Explanation:

Booms and skimmers are the primary method used to clean up oil spills in marine environments. Booms are floating barriers that contain the oil, while skimmers collect the oil from the water's surface.

Which international convention is specifically designed to address oil pollution from ships?

  1. MARPOL 73/78

  2. London Convention

  3. Basel Convention

  4. Stockholm Convention


Correct Option: A
Explanation:

MARPOL 73/78 (International Convention for the Prevention of Pollution from Ships) is the primary international convention designed to address oil pollution from ships. It sets standards for the prevention of oil pollution from ships, including requirements for oil tankers to have double hulls and for ships to have oil spill response plans.

What is the term used to describe the process by which oil becomes weathered and broken down in the marine environment?

  1. Biodegradation

  2. Photooxidation

  3. Evaporation

  4. Dispersion


Correct Option:
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.

Which type of oil spill is considered to be the most difficult to clean up?

  1. Light crude oil spill

  2. Heavy crude oil spill

  3. Emulsified oil spill

  4. Subsea oil spill


Correct Option: D
Explanation:

Subsea oil spills, which occur when oil is released underwater, are considered to be the most difficult to clean up. This is because the oil is dispersed and mixed with water, making it difficult to contain and recover.

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


Correct Option: B
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.

Which type of marine habitat is particularly vulnerable to oil pollution?

  1. Coral reefs

  2. Mangrove forests

  3. Seagrass beds

  4. All of the above


Correct Option:
Explanation:

Coral reefs, mangrove forests, and seagrass beds are all marine habitats that are particularly vulnerable to oil pollution. These habitats are highly biodiverse and provide important ecosystem services, such as food and shelter for marine life. Oil pollution can damage these habitats and the organisms that depend on them.

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


Correct Option: A
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.

Which of the following factors can affect the rate at which oil is weathered in the marine environment?

  1. Temperature

  2. Wave action

  3. Sunlight

  4. All of the above


Correct Option:
Explanation:

The rate at which oil is weathered in the marine environment can be affected by a number of factors, including temperature, wave action, and sunlight. Higher temperatures and wave action can accelerate the weathering process, while sunlight can promote photooxidation.

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


Correct Option: C
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.

Which of the following is not a potential consequence of oil pollution on marine ecosystems?

  1. Reduced biodiversity

  2. Increased productivity

  3. Habitat destruction

  4. Food chain disruption


Correct Option: B
Explanation:

Increased productivity is not a potential consequence of oil pollution on marine ecosystems. Oil pollution typically leads to reduced biodiversity, habitat destruction, and food chain disruption.
