Fossil fuel extraction activities contribute to greenhouse gas emissions primarily through ___________ Methane leakage from oil and natural gas systems Release of oxygen during drilling processes Nitrogen emissions from geological formations Carbon dioxide emissions only during extraction 2. Deforestation is considered a “double impact” on climate change because it ___________ Affects only soil properties without atmospheric consequences Increases atmospheric oxygen concentrations Releases stored carbon and simultaneously reduces carbon sink capacity Influences only hydrological processes 3. Improved manure management practices primarily reduce emissions of ___________ Oxygen released Nitrogen Carbon dioxide Methane and nitrous oxide 4. The largest anthropogenic source of carbon dioxide (CO₂) emissions globally is ___________ Plant respiration Volcanic eruptions Combustion of fossil fuels Oceanic outgassing 5. The most effective long-term climate change mitigation strategy is ___________ Increasing atmospheric aerosols Nitrous oxide control only Methane reduction alone Sustained reduction of carbon dioxide (CO₂) emissions 6. The factor that most strongly influences comparisons of Global Warming Potential (GWP) among greenhouse gases is the ___________ Wind speed affecting dispersion Selected time horizon over which warming is evaluated Soil type influencing emissions Relative humidity of the atmosphere 7. Which of the following best represents a biogeochemical tipping point? Wind circulation change AMOC slowdown Ice sheet collapse Permafrost carbon release 8. The effectiveness of climate mitigation strategies is primarily determined by ___________ Economic cost alone Ambient temperature conditions only Nature of emission sources and greenhouse gas characteristics Technological availability only 9. Methane (CH₄) is more potent as a greenhouse gas but less abundant in the atmosphere than ___________ Ozone (O₃) Oxygen (O₂) Carbon dioxide (CO₂) Nitrous oxide (N₂O) 10. Methane (CH₄) is prioritized for near-term climate mitigation primarily because of its ___________ Low emission contribution globally Low radiative efficiency Very long atmospheric lifetime High short-term radiative forcing and warming impact Loading … Question 1 of 10Climate Change MCQs Set 29 (200+ Questions with Answers) Climate Change MCQs Set 29 (200+ Questions with Answers) 1.
