Which method is commonly used to clean oil spills on water surfaces?

• A. Siphoning off or skimming
• B. Planting mangroves to absorb oil
• C. Releasing detergents into water
• D. Deep drilling to remove oil

Answer: (A)

Cleaning oil spills on water surfaces relies on physically removing the slick from the surface using skimmers. This approach target’s the problem where oil floats and can spread rapidly, so gear like skimmers and siphons can recover the oil from the water and keep it from spreading, often working alongside containment booms to corral the slick. It’s the best option here because it directly removes oil with minimal additional pollution and is scalable to spills of various sizes. The other ideas aren’t used as cleanup methods on the surface: mangroves can’t respond quickly to an oil slick and aren’t a practical cleanup tool; releasing detergents or chemical dispersants can spread the oil and harm marine life; deep drilling is an extraction activity, not a cleanup step.
