Which of the following is NOT a major source of oil pollution in the ocean?

  1. Oil spills from tankers

  2. Natural seeps from the seafloor

  3. Urban runoff

  4. Bilge water from ships


Correct Option: B
Explanation:

While natural seeps do contribute to oil pollution, they are not as significant as the other sources mentioned.

What is the primary impact of oil pollution on marine organisms?

  1. Direct toxicity

  2. Habitat destruction

  3. Food chain disruption

  4. All of the above


Correct Option: D
Explanation:

Oil pollution can have a variety of negative effects on marine organisms, including direct toxicity, habitat destruction, and food chain disruption.

Which type of marine organism is most vulnerable to oil pollution?

  1. Fish

  2. Seabirds

  3. Marine mammals

  4. Coral reefs


Correct Option: B
Explanation:

Seabirds are particularly vulnerable to oil pollution because their feathers can become coated in oil, which reduces their ability to fly and stay warm.

What is the process by which oil is broken down in the marine environment?

  1. Biodegradation

  2. Photolysis

  3. Evaporation

  4. All of the above


Correct Option: D
Explanation:

Oil is broken down in the marine environment through a combination of biodegradation, photolysis, and evaporation.

What is the long-term impact of oil pollution on marine ecosystems?

  1. Reduced biodiversity

  2. Changes in ecosystem structure and function

  3. Accumulation of toxins in the food chain

  4. All of the above


Correct Option: D
Explanation:

Oil pollution can have a number of long-term impacts on marine ecosystems, including reduced biodiversity, changes in ecosystem structure and function, and accumulation of toxins in the food chain.

What is the most effective way to prevent oil pollution in the ocean?

  1. Reduce our reliance on fossil fuels

  2. Improve oil spill response capabilities

  3. Educate the public about the dangers of oil pollution

  4. All of the above


Correct Option: D
Explanation:

Preventing oil pollution requires a combination of efforts, including reducing our reliance on fossil fuels, improving oil spill response capabilities, and educating the public about the dangers of oil pollution.

What is the name of the international convention that aims to prevent and control oil pollution from ships?

  1. MARPOL 73/78

  2. UNCLOS

  3. Kyoto Protocol

  4. Paris Agreement


Correct Option: A
Explanation:

MARPOL 73/78 is the International Convention for the Prevention of Pollution from Ships, which aims to prevent and control oil pollution from ships.

What is the purpose of an oil spill dispersant?

  1. To break up oil slicks into smaller droplets

  2. To absorb oil from the water

  3. To solidify oil so it can be removed

  4. To prevent oil from spreading


Correct Option: A
Explanation:

Oil spill dispersants are chemicals that are used to break up oil slicks into smaller droplets, which makes them easier to disperse and degrade.

What is the name of the largest oil spill in history?

  1. Deepwater Horizon oil spill

  2. Exxon Valdez oil spill

  3. BP oil spill

  4. Amoco Cadiz oil spill


Correct Option: A
Explanation:

The Deepwater Horizon oil spill was the largest oil spill in history, releasing an estimated 4.9 million barrels of oil into the Gulf of Mexico.

What is the name of the process by which oil is removed from the surface of the water?

  1. Skimming

  2. Dispersing

  3. Burning

  4. Sorbing


Correct Option: A
Explanation:

Skimming is the process by which oil is removed from the surface of the water using a variety of devices, such as booms, skimmers, and sorbents.

What is the name of the process by which oil is burned on the surface of the water?

  1. In situ burning

  2. Controlled burning

  3. Prescribed burning

  4. Wildfire


Correct Option: A
Explanation:

In situ burning is the process by which oil is burned on the surface of the water in a controlled manner.

What is the name of the process by which oil is solidified so it can be removed from the water?

  1. Solidification

  2. Gelation

  3. Coagulation

  4. Flocculation


Correct Option: A
Explanation:

Solidification is the process by which oil is solidified so it can be removed from the water using a variety of methods, such as sorbents, gels, and solidifiers.

What is the name of the process by which oil is absorbed by a material?

  1. Sorption

  2. Adsorption

  3. Absorption

  4. Desorption


Correct Option: A
Explanation:

Sorption is the process by which oil is absorbed by a material, such as a sorbent, gel, or solidifier.

What is the name of the process by which oil is released from a material?

  1. Desorption

  2. Elution

  3. Extraction

  4. Leaching


Correct Option: A
Explanation:

Desorption is the process by which oil is released from a material, such as a sorbent, gel, or solidifier.
