Carbon dioxide and methane as greenhouse gases
Question
- A. By using fertilizers
- B. Through anaerobic decomposition
- C. By increasing soil erosion
- D. By reducing water levels
Answer
The correct option is Through anaerobic decomposition. This answer is correct because it matches the approved learning objective to describe how cattle and rice fields can contribute to methane emissions in the subtopic Human activities which contribute to an increase in greenhouse gases in the atmosphere.
Explanation
The correct option is Through anaerobic decomposition. Through anaerobic decomposition is correct because it directly supports the approved learning objective to describe how cattle and rice fields can contribute to methane emissions. This belongs to the subtopic Human activities which contribute to an increase in greenhouse gases in the atmosphere 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 Human activities which contribute to an increase in greenhouse gases in the atmosphere.
Common mistake
Cattle and Methane Emissions
Students often confuse the sources of methane emissions, thinking only cattle contribute to it, ignoring rice fields.
Remember that both cattle and rice fields are significant sources of methane emissions; consider both when describing their contributions.
