🔍 Key Concepts

• Purpose of chemical agents (dispersants) in oil spill response • Difference between dispersing, absorbing, sinking, and dissolving oil • Environmental trade‑offs of using chemical agents on spills

💭 Think About

• Ask yourself: Do chemical agents usually make the oil float more, sink, spread out, or clump up for collection? • Which option best matches the idea of breaking oil into smaller droplets so natural processes (like bacteria and waves) can work on it? • Which choices describe things that are generally NOT allowed because they just hide the oil rather than help remove its impact?

✅ Before You Answer

• Eliminate any option that suggests simply hiding the oil (like making it sink) instead of addressing the pollution problem. • Focus on what dispersants actually do: they change the form and distribution of oil, not magically make it vanish. • Make sure the option you choose reflects assisting cleanup or natural removal, not just changing where the oil is located.
