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