Carbon and Fossil Fuels Questions

Multiple choice

Which type of oil spill is considered to be the most difficult to clean up?

  1. Light crude oil spill

  2. Heavy crude oil spill

  3. Emulsified oil spill

  4. Subsea oil spill
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Subsea oil spills, which occur when oil is released underwater, are considered to be the most difficult to clean up. This is because the oil is dispersed and mixed with water, making it difficult to contain and recover.
