What is the primary source of ocean pollution?

  1. Natural Causes

  2. Industrial Waste

  3. Agricultural Runoff

  4. Oil Spills


Correct Option: B
Explanation:

Industrial activities, such as manufacturing and mining, release harmful chemicals and pollutants into the ocean.

Which type of plastic pollution is most commonly found in the ocean?

  1. Microplastics

  2. Plastic Bags

  3. Fishing Nets

  4. Plastic Bottles


Correct Option: A
Explanation:

Microplastics, tiny plastic particles less than 5 millimeters in size, are a major source of plastic pollution in the ocean.

How does ocean acidification impact marine life?

  1. Coral Bleaching

  2. Shellfish Weakening

  3. Fish Population Decline

  4. All of the Above


Correct Option: D
Explanation:

Ocean acidification affects marine life in various ways, including coral bleaching, shellfish weakening, and fish population decline.

What is the main cause of ocean acidification?

  1. Volcanic Eruptions

  2. Natural Carbon Cycle

  3. Human Activities

  4. Ocean Currents


Correct Option: C
Explanation:

Human activities, particularly the burning of fossil fuels, release carbon dioxide into the atmosphere, which is absorbed by the ocean, leading to ocean acidification.

Which marine species is particularly vulnerable to ocean acidification?

  1. Jellyfish

  2. Sea Turtles

  3. Coral Reefs

  4. Dolphins


Correct Option: C
Explanation:

Coral reefs are highly susceptible to ocean acidification, as the acidic conditions hinder their ability to build and maintain their skeletons.

What is the term for the process by which marine organisms remove carbon dioxide from the ocean?

  1. Ocean Sequestration

  2. Ocean Acidification

  3. Ocean Alkalinity

  4. Ocean Carbon Capture


Correct Option: D
Explanation:

Ocean Carbon Capture refers to the process by which marine organisms, such as phytoplankton, absorb carbon dioxide from the ocean.

Which international agreement aims to reduce ocean pollution from ships?

  1. Kyoto Protocol

  2. Montreal Protocol

  3. MARPOL Convention

  4. Paris Agreement


Correct Option: C
Explanation:

The MARPOL Convention (International Convention for the Prevention of Pollution from Ships) aims to minimize pollution from ships, including oil, chemicals, and garbage.

What is the term for the accumulation of plastic debris in the ocean?

  1. Ocean Dumping

  2. Ocean Garbage Patch

  3. Ocean Pollution

  4. Ocean Acidification


Correct Option: B
Explanation:

Ocean Garbage Patch refers to the accumulation of plastic debris in certain areas of the ocean, forming large floating masses of plastic waste.

Which type of marine life is often affected by entanglement in plastic debris?

  1. Sea Turtles

  2. Whales

  3. Dolphins

  4. All of the Above


Correct Option: D
Explanation:

Sea turtles, whales, and dolphins are among the marine species that can become entangled in plastic debris, leading to injury or death.

What is the term for the process by which harmful substances in the ocean are concentrated in the tissues of marine organisms?

  1. Bioaccumulation

  2. Biomagnification

  3. Bioremediation

  4. Biodegradation


Correct Option: A
Explanation:

Bioaccumulation refers to the process by which harmful substances in the ocean, such as heavy metals and toxins, accumulate in the tissues of marine organisms.

Which marine ecosystem is particularly vulnerable to ocean acidification?

  1. Coral Reefs

  2. Mangrove Forests

  3. Seagrass Beds

  4. Kelp Forests


Correct Option: A
Explanation:

Coral reefs are highly vulnerable to ocean acidification, as the acidic conditions hinder the growth and survival of corals.

What is the term for the process by which ocean currents transport pollutants over long distances?

  1. Ocean Circulation

  2. Ocean Convection

  3. Ocean Gyres

  4. Ocean Currents


Correct Option: D
Explanation:

Ocean currents can transport pollutants over long distances, spreading the impact of pollution to different parts of the ocean.

Which type of plastic pollution is often ingested by marine animals, mistaking it for food?

  1. Plastic Bags

  2. Plastic Bottles

  3. Microplastics

  4. Fishing Nets


Correct Option: C
Explanation:

Microplastics, due to their small size, can be mistaken for food by marine animals, leading to ingestion and potential health issues.

What is the term for the process by which marine organisms break down and remove pollutants from the ocean?

  1. Bioremediation

  2. Biodegradation

  3. Bioaccumulation

  4. Biomagnification


Correct Option: B
Explanation:

Biodegradation refers to the process by which marine organisms break down and remove pollutants from the ocean through natural biological processes.

Which international organization is responsible for coordinating efforts to address ocean pollution?

  1. World Health Organization (WHO)

  2. United Nations Environment Programme (UNEP)

  3. International Monetary Fund (IMF)

  4. World Bank


Correct Option: B
Explanation:

The United Nations Environment Programme (UNEP) is the leading international organization responsible for coordinating efforts to address environmental issues, including ocean pollution.
