What is the primary source of ocean pollution?

  1. Natural Disasters

  2. Industrial Waste

  3. Agricultural Runoff

  4. Volcanic Eruptions


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 particularly harmful to marine life?

  1. Microplastics

  2. Plastic Bags

  3. Plastic Bottles

  4. Plastic Straws


Correct Option: A
Explanation:

Microplastics, tiny plastic particles less than 5mm in size, can be ingested by marine organisms and accumulate in their tissues, causing health problems.

What is the term used to describe the accumulation of plastic waste in the ocean?

  1. Ocean Acidification

  2. Ocean Gyres

  3. Plastic Soup

  4. Ocean Desertification


Correct Option: C
Explanation:

Plastic Soup refers to the vast collection of plastic debris floating in the ocean, particularly in areas known as ocean gyres.

Which marine species is most affected by entanglement in plastic waste?

  1. Sea Turtles

  2. Whales

  3. Dolphins

  4. Fish


Correct Option: A
Explanation:

Sea turtles are particularly vulnerable to entanglement in plastic debris, which can restrict their movement, cause injury, and lead to death.

What is the primary cause of coral reef degradation?

  1. Climate Change

  2. Overfishing

  3. Pollution

  4. Coastal Development


Correct Option: A
Explanation:

Climate change, particularly rising sea temperatures, is the primary cause of coral reef degradation, leading to coral bleaching and death.

Which fishing practice is known for its indiscriminate catch and bycatch of marine life?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Spearfishing


Correct Option: A
Explanation:

Trawling involves dragging a large net along the seafloor, capturing a wide range of marine life, including non-target species and juveniles.

What is the term used to describe the process of restoring damaged marine ecosystems?

  1. Ocean Restoration

  2. Marine Conservation

  3. Ocean Cleanup

  4. Marine Rehabilitation


Correct Option: A
Explanation:

Ocean Restoration refers to the active efforts to restore degraded marine ecosystems to their natural state, often involving habitat restoration and species reintroduction.

Which international agreement aims to prevent pollution from ships and protect the marine environment?

  1. MARPOL Convention

  2. Kyoto Protocol

  3. Paris Agreement

  4. Ramsar Convention


Correct Option: A
Explanation:

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

What is the term used to describe the process of reducing the amount of waste produced?

  1. Waste Reduction

  2. Recycling

  3. Composting

  4. Landfilling


Correct Option: A
Explanation:

Waste Reduction refers to efforts to minimize the amount of waste generated at the source, reducing the burden on waste management systems and the environment.

Which marine species is known for its ability to filter large volumes of water and remove pollutants?

  1. Oysters

  2. Clams

  3. Mussels

  4. Sea Urchins


Correct Option: A
Explanation:

Oysters are filter feeders that can remove pollutants and excess nutrients from the water, helping to improve water quality.

What is the term used to describe the process of converting waste into reusable materials?

  1. Recycling

  2. Composting

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Recycling involves converting waste materials into new materials and objects, reducing the need for raw materials and minimizing waste.

Which marine mammal is known for its role in controlling jellyfish populations?

  1. Dolphins

  2. Sea Lions

  3. Whales

  4. Manatees


Correct Option: A
Explanation:

Dolphins are known to prey on jellyfish, helping to control their populations and maintain a balance in marine ecosystems.

What is the term used to describe the process of breaking down organic waste into a nutrient-rich soil amendment?

  1. Composting

  2. Recycling

  3. Incineration

  4. Landfilling


Correct Option: A
Explanation:

Composting involves breaking down organic waste, such as food scraps and yard waste, into a nutrient-rich soil amendment that can be used in gardening and agriculture.

Which marine species is known for its ability to clean up oil spills and other pollutants?

  1. Sea Turtles

  2. Whales

  3. Dolphins

  4. Mussels


Correct Option: D
Explanation:

Mussels are filter feeders that can remove pollutants, including oil, from the water, helping to clean up oil spills and improve water quality.

What is the term used to describe the process of disposing of waste by burying it in the ground?

  1. Landfilling

  2. Recycling

  3. Composting

  4. Incineration


Correct Option: A
Explanation:

Landfilling involves burying waste in the ground, typically in a designated area called a landfill, where it is compacted and covered to minimize environmental impacts.
