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

  1. Oil spills

  2. Plastic waste

  3. Agricultural runoff

  4. Volcanic eruptions


Correct Option: D
Explanation:

Volcanic eruptions are not a major source of ocean pollution, unlike oil spills, plastic waste, and agricultural runoff.

How does ocean pollution contribute to climate change?

  1. By releasing greenhouse gases

  2. By altering ocean currents

  3. By reducing biodiversity

  4. All of the above


Correct Option: D
Explanation:

Ocean pollution contributes to climate change by releasing greenhouse gases, altering ocean currents, and reducing biodiversity, all of which have significant impacts on the global climate system.

Which type of plastic pollution is particularly harmful to marine life?

  1. Microplastics

  2. Single-use plastics

  3. Large plastic debris

  4. All of the above


Correct Option: D
Explanation:

All types of plastic pollution, including microplastics, single-use plastics, and large plastic debris, can harm marine life through ingestion, entanglement, and habitat degradation.

What is the primary cause of ocean acidification?

  1. Increased carbon dioxide levels in the atmosphere

  2. Oil spills

  3. Agricultural runoff

  4. Volcanic eruptions


Correct Option: A
Explanation:

Ocean acidification is primarily caused by increased carbon dioxide levels in the atmosphere, which dissolve in seawater and form carbonic acid.

How does ocean acidification affect marine ecosystems?

  1. It harms coral reefs and shellfish

  2. It disrupts the food chain

  3. It reduces biodiversity

  4. All of the above


Correct Option: D
Explanation:

Ocean acidification harms coral reefs and shellfish, disrupts the food chain, and reduces biodiversity, posing significant threats to marine ecosystems.

What is the main cause of coral bleaching?

  1. Increased ocean temperatures

  2. Pollution

  3. Overfishing

  4. Habitat destruction


Correct Option: A
Explanation:

Coral bleaching is primarily caused by increased ocean temperatures, which stress corals and cause them to expel their symbiotic algae, leading to loss of color and vulnerability to disease.

How does climate change affect ocean currents?

  1. It can alter their direction and strength

  2. It can lead to the formation of new currents

  3. It can disrupt marine ecosystems

  4. All of the above


Correct Option: D
Explanation:

Climate change can alter the direction and strength of ocean currents, lead to the formation of new currents, and disrupt marine ecosystems, impacting weather patterns and marine life distribution.

What is the term for the phenomenon where warmer waters move towards the poles?

  1. Ocean acidification

  2. Ocean warming

  3. Ocean circulation

  4. Polar amplification


Correct Option: D
Explanation:

Polar amplification refers to the phenomenon where warmer waters move towards the poles, resulting in more rapid warming in polar regions compared to other parts of the globe.

How does ocean pollution affect human health?

  1. It can contaminate seafood

  2. It can cause respiratory problems

  3. It can lead to skin irritation

  4. All of the above


Correct Option: D
Explanation:

Ocean pollution can contaminate seafood, causing health risks to humans who consume it. It can also cause respiratory problems and skin irritation due to exposure to pollutants in the air and water.

What is the term for the process of removing carbon dioxide from the atmosphere?

  1. Carbon sequestration

  2. Carbon capture

  3. Carbon storage

  4. All of the above


Correct Option: D
Explanation:

Carbon sequestration, carbon capture, and carbon storage are all terms used to describe the process of removing carbon dioxide from the atmosphere, typically through natural or technological means.

Which of the following is NOT a potential solution to reduce ocean pollution?

  1. Reducing plastic production

  2. Improving waste management

  3. Encouraging sustainable fishing practices

  4. Planting trees


Correct Option: D
Explanation:

Planting trees is not directly related to reducing ocean pollution, although it can contribute to climate change mitigation by absorbing carbon dioxide from the atmosphere.

What is the term for the phenomenon where the ocean absorbs heat from the atmosphere?

  1. Ocean warming

  2. Ocean heat uptake

  3. Ocean circulation

  4. Ocean acidification


Correct Option: B
Explanation:

Ocean heat uptake refers to the phenomenon where the ocean absorbs heat from the atmosphere, playing a crucial role in regulating Earth's climate.

How does climate change affect sea levels?

  1. It causes sea levels to rise

  2. It causes sea levels to fall

  3. It has no effect on sea levels

  4. It depends on the region


Correct Option: A
Explanation:

Climate change causes sea levels to rise primarily due to thermal expansion of ocean water as it warms and the melting of glaciers and ice sheets.

What is the term for the phenomenon where ocean acidification reduces the ability of marine organisms to build their shells and skeletons?

  1. Ocean acidification

  2. Ocean warming

  3. Ocean circulation

  4. Ocean deoxygenation


Correct Option: A
Explanation:

Ocean acidification refers to the phenomenon where increased carbon dioxide levels in the atmosphere lead to a decrease in the pH of ocean water, making it more acidic and affecting the ability of marine organisms to build their shells and skeletons.

What is the term for the phenomenon where the ocean loses oxygen?

  1. Ocean acidification

  2. Ocean warming

  3. Ocean circulation

  4. Ocean deoxygenation


Correct Option: D
Explanation:

Ocean deoxygenation refers to the phenomenon where the ocean loses oxygen, primarily due to climate change-induced warming and changes in ocean circulation patterns.
