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