Precision agriculture can mitigate high global warming potential (GWP) emissions primarily by ________ Increasing methane emissions Increasing fertilizer use Reducing crop yield Optimizing nitrogen application to reduce N₂O emissions 2. Carbon budgets are primarily determined based on __________ Annual emissions Cumulative CO₂ emissions Temperature Rainfall 3. Which factor primarily influences surface albedo? Atmospheric pressure Wind speed Surface characteristics Latitude only 4. Which gas has the highest GWP over 100 years among common GHGs? O₂ CH₄ CO₂ N₂O 5. Methane (CH₄) mitigation policies can produce rapid climate benefits primarily because methane has a ___________ Low global warming potential Low radiative forcing High emission rate Short atmospheric lifetime 6. Why is CO₂ assigned a GWP of 1? It is most abundant It has the shortest lifetime It serves as the baseline reference gas It has no warming effect 7. Which factor directly determines the accumulation of Growing Degree Days (GDD) in crop growth analysis? Temperature above the base (threshold) temperature Crop growth habit (C3, C4, CAM) Root depth and type Frost-free days 8. A climate mitigation strategy focusing only on CO₂ may be insufficient because:__________ CO₂ concentration is low in the atmosphere Ozone dominates in the stratosphere Methane is absent in the troposphere Non-CO₂ gases also contribute significantly 9. Which combination is correctly matched? DTR – annual variation GDD – rainfall index Q₁₀ – temperature sensitivity of biological processes ATR – daily variation 10. Which agricultural approach is most effective in reducing the carbon footprint while maintaining productivity? Afforestation More irrigation More fertilizer application Precision nutrient and water management Loading … Question 1 of 10 Climate Change MCQs Set 6 (200+ Questions with Answers)
