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