Carbon dioxide and methane as greenhouse gases
Question
- A. By increasing fossil fuel consumption
- B. By capturing and storing carbon dioxide emissions
- C. By promoting the use of coal
- D. By reducing the need for energy efficiency measures
Answer
The correct option is By capturing and storing carbon dioxide emissions. This answer is correct because it matches the approved learning objective to describe how carbon capture and storage may reduce carbon dioxide emissions from power stations in the subtopic The carbon footprint and its reduction.
Explanation
The correct option is By capturing and storing carbon dioxide emissions. By capturing and storing carbon dioxide emissions is correct because it directly supports the approved learning objective to describe how carbon capture and storage may reduce carbon dioxide emissions from power stations. This belongs to the subtopic The carbon footprint and its reduction within Carbon dioxide and methane as greenhouse gases, so the explanation must stay tied to that curriculum context. The other options are incorrect because they either do not answer this learning objective, use a vague statement, or move away from The carbon footprint and its reduction.
Common mistake
Misunderstanding Carbon Capture
Students often think that carbon capture and storage completely eliminates carbon dioxide emissions from power stations.
Clarify that carbon capture and storage reduces emissions but does not eliminate them entirely; it captures a portion of CO2 for storage.
