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