Improved manure management practices primarily reduce emissions of ___________ Nitrogen Oxygen released Methane and nitrous oxide Carbon dioxide 2. The factor that most strongly influences comparisons of Global Warming Potential (GWP) among greenhouse gases is the ___________ Relative humidity of the atmosphere Soil type influencing emissions Selected time horizon over which warming is evaluated Wind speed affecting dispersion 3. 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 4. 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 5. The most effective long-term climate change mitigation strategy is ___________ Sustained reduction of carbon dioxide (CO₂) emissions Nitrous oxide control only Methane reduction alone Increasing atmospheric aerosols 6. Methane (CH₄) is more potent as a greenhouse gas but less abundant in the atmosphere than ___________ Ozone (O₃) Oxygen (O₂) Nitrous oxide (N₂O) Carbon dioxide (CO₂) 7. Methane (CH₄) is prioritized for near-term climate mitigation primarily because of its ___________ Very long atmospheric lifetime Low emission contribution globally Low radiative efficiency High short-term radiative forcing and warming impact 8. Which of the following best represents a biogeochemical tipping point? AMOC slowdown Permafrost carbon release Ice sheet collapse Wind circulation change 9. The effectiveness of climate mitigation strategies is primarily determined by ___________ Ambient temperature conditions only Nature of emission sources and greenhouse gas characteristics Economic cost alone Technological availability only 10. The largest anthropogenic source of carbon dioxide (CO₂) emissions globally is ___________ Combustion of fossil fuels Plant respiration Volcanic eruptions Oceanic outgassing Loading … Question 1 of 10Climate Change MCQs Set 29 (200+ Questions with Answers) Climate Change MCQs Set 29 (200+ Questions with Answers) 1.
