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