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