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