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