Which human activity poses the greatest threat to coral reefs?

  1. Overfishing

  2. Pollution

  3. Climate Change

  4. Tourism


Correct Option: C
Explanation:

Climate change, particularly rising sea temperatures, leads to coral bleaching and death, causing significant damage to coral reefs.

What is the primary cause of ocean acidification?

  1. Volcanic Eruptions

  2. Deforestation

  3. Burning Fossil Fuels

  4. Agricultural Runoff


Correct Option: C
Explanation:

The burning of fossil fuels releases carbon dioxide into the atmosphere, which dissolves in the ocean and forms carbonic acid, leading to ocean acidification.

Which marine species is most vulnerable to bycatch, the accidental capture of non-target species during fishing?

  1. Tuna

  2. Sharks

  3. Dolphins

  4. Sea Turtles


Correct Option: D
Explanation:

Sea turtles are particularly susceptible to bycatch due to their slow swimming speed and tendency to inhabit areas where fishing activities are common.

What is the primary goal of marine protected areas (MPAs)?

  1. Promoting Sustainable Fishing

  2. Preserving Marine Biodiversity

  3. Facilitating Marine Research

  4. Developing Coastal Tourism


Correct Option: B
Explanation:

Marine protected areas are designated to protect and conserve marine ecosystems and biodiversity, ensuring the long-term health of these areas.

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

  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) is designed to minimize pollution from ships, including oil, chemicals, and sewage.

What is the term used to describe the process of restoring degraded marine ecosystems to their natural state?

  1. Marine Restoration

  2. Marine Conservation

  3. Marine Preservation

  4. Marine Rehabilitation


Correct Option: A
Explanation:

Marine restoration involves active efforts to restore damaged marine ecosystems, such as coral reefs and mangrove forests, to their original condition.

Which marine species is known for its ability to filter large volumes of water, removing pollutants and improving water quality?

  1. Oysters

  2. Clams

  3. Mussels

  4. Scallops


Correct Option: A
Explanation:

Oysters are filter feeders that play a crucial role in improving water quality by removing pollutants and excess nutrients from the water.

What is the main purpose of establishing marine sanctuaries?

  1. Promoting Recreational Fishing

  2. Preserving Cultural Heritage

  3. Facilitating Commercial Shipping

  4. Protecting Marine Biodiversity


Correct Option: D
Explanation:

Marine sanctuaries are designated to protect and conserve marine ecosystems and biodiversity, ensuring the long-term health of these areas.

Which fishing practice involves dragging a heavy net along the seafloor, causing significant damage to marine habitats?

  1. Trawling

  2. Gillnetting

  3. Longlining

  4. Seine Fishing


Correct Option: A
Explanation:

Trawling involves dragging a large net along the seafloor, often resulting in the destruction of marine habitats and the capture of non-target species.

What is the term used to describe the process of reducing the impact of human activities on marine ecosystems?

  1. Marine Mitigation

  2. Marine Conservation

  3. Marine Adaptation

  4. Marine Sustainability


Correct Option: A
Explanation:

Marine mitigation involves taking measures to reduce the negative impacts of human activities on marine ecosystems, such as pollution, overfishing, and habitat destruction.

Which international organization is responsible for coordinating global efforts to conserve marine biodiversity?

  1. World Health Organization (WHO)

  2. United Nations Environment Programme (UNEP)

  3. International Monetary Fund (IMF)

  4. World Trade Organization (WTO)


Correct Option: B
Explanation:

The United Nations Environment Programme (UNEP) is responsible for coordinating global efforts to protect the environment, including marine biodiversity conservation.

What is the primary cause of the decline in mangrove forests, which are important coastal ecosystems?

  1. Climate Change

  2. Deforestation

  3. Pollution

  4. Overfishing


Correct Option: B
Explanation:

Deforestation, particularly for coastal development and agriculture, is the primary cause of the decline in mangrove forests.

Which marine mammal is known for its long migrations and complex social structures?

  1. Whales

  2. Dolphins

  3. Seals

  4. Sea Lions


Correct Option: A
Explanation:

Whales, particularly humpback whales, are known for their long migrations and complex social structures, including intricate songs and cooperative feeding behaviors.

What is the term used to describe the process of introducing non-native species into a marine ecosystem?

  1. Marine Invasion

  2. Marine Adaptation

  3. Marine Colonization

  4. Marine Migration


Correct Option: A
Explanation:

Marine invasion refers to the introduction of non-native species into a marine ecosystem, often through human activities such as shipping and aquaculture.

Which international agreement aims to regulate fishing activities and prevent overfishing?
