Explanation:

Industrial activities, including the discharge of untreated wastewater and chemicals, are the leading cause of marine pollution.

Which type of marine pollution is caused by the accumulation of plastic waste in the ocean?

  1. Oil Spills

  2. Eutrophication

  3. Ocean Acidification

  4. Plastic Pollution


Correct Option: D
Explanation:

Plastic pollution refers to the accumulation of plastic waste in the marine environment, posing a significant threat to marine life and ecosystems.

What is the process by which excess nutrients, such as nitrogen and phosphorus, enter coastal waters, leading to algal blooms and oxygen depletion?

  1. Ocean Acidification

  2. Eutrophication

  3. Oil Spills

  4. Plastic Pollution


Correct Option: B
Explanation:

Eutrophication is the process where excessive nutrients, often from agricultural runoff, cause algal blooms and oxygen depletion in coastal waters.

Which marine species is particularly vulnerable to entanglement in fishing gear, leading to bycatch and population decline?

  1. Sea Turtles

  2. Sharks

  3. Whales

  4. Dolphins


Correct Option: A
Explanation:

Sea turtles are highly susceptible to entanglement in fishing gear, resulting in bycatch and contributing to their population decline.

What is the term used to describe the gradual increase in the acidity of the ocean due to the absorption of carbon dioxide from the atmosphere?

  1. Ocean Acidification

  2. Eutrophication

  3. Oil Spills

  4. Plastic Pollution


Correct Option: A
Explanation:

Ocean acidification refers to the ongoing decrease in the pH of the ocean, caused by the absorption of carbon dioxide from the atmosphere.
