Which type of marine debris is most commonly found in oceans?

  1. Plastic

  2. Metal

  3. Paper

  4. Glass


Correct Option: A
Explanation:

Plastic is the most common type of marine debris, accounting for over 80% of all ocean pollution.

What is the primary source of plastic pollution in oceans?

  1. Industrial Waste

  2. Agricultural Runoff

  3. Shipping Activities

  4. Land-based Litter


Correct Option: D
Explanation:

Land-based litter, such as plastic bags, bottles, and straws, is the primary source of plastic pollution in oceans.

How long does it take for plastic to decompose in the ocean?

  1. 10 years

  2. 100 years

  3. 1,000 years

  4. Never


Correct Option: D
Explanation:

Plastic does not decompose in the ocean; instead, it breaks down into smaller pieces called microplastics, which can persist for centuries.

What are the primary impacts of ocean pollution on marine life?

  1. Habitat Destruction

  2. Ingestion of Plastic

  3. Entanglement

  4. All of the above


Correct Option: D
Explanation:

Ocean pollution can cause habitat destruction, ingestion of plastic by marine animals, entanglement in plastic debris, and other negative impacts on marine life.

Which marine species is most affected by plastic pollution?

  1. Sea Turtles

  2. Whales

  3. Dolphins

  4. Seabirds


Correct Option: A
Explanation:

Sea turtles are particularly vulnerable to plastic pollution, as they often mistake plastic bags and other debris for food.

What is the Great Pacific Garbage Patch?

  1. A large accumulation of plastic debris in the North Pacific Ocean

  2. A type of marine organism

  3. A deep-sea trench

  4. A coral reef


Correct Option: A
Explanation:

The Great Pacific Garbage Patch is a vast accumulation of plastic debris in the North Pacific Ocean, estimated to cover an area twice the size of Texas.

What is the primary solution to address ocean pollution and marine debris?

  1. Reduce Plastic Production

  2. Improve Waste Management

  3. Promote Recycling

  4. All of the above


Correct Option: D
Explanation:

To effectively address ocean pollution and marine debris, a combination of reducing plastic production, improving waste management, and promoting recycling is necessary.

What is the role of international cooperation in combating ocean pollution?

  1. Encouraging Global Action

  2. Setting International Standards

  3. Facilitating Knowledge Sharing

  4. All of the above


Correct Option: D
