Q.1	Two islands in the Pacific Ocean experience similar climates but have different levels of deforestation. Island A has lost 80% of its original forest cover, while Island B has maintained 90% of its forest. Over the past decade, Island A has experienced more frequent and intense heat waves compared to Island B. Which of the following is the most likely explanation for this difference?
	a) Island B benefits from cooler ocean currents that moderate its climate, while Island A does not.		b) Island A's proximity to volcanic activity contributes to increased heatwaves.
	c) Island A has a higher concentration of greenhouse gases in its atmosphere due to reduced carbon sequestration by forests.		d) Island B's higher elevation reduces the likelihood of extreme heatwaves.

Q.2	A small community in a remote, arid region is facing water scarcity. Their traditional farming practices are no longer sufficient to sustain the community's needs. To ensure long-term food security and water conservation, the community is considering adopting a new farming approach. Which farming practice would be the most sustainable option for the community to adopt in the long term, considering both water conservation and food production?
	a) Conventional irrigation using sprinklers		b) Organic farming with flood irrigation techniques
	c) Agroecological practices incorporating drip irrigation systems		d) Intensive farming with open furrow irrigation methods

Q.3	You are a farmer in a region with a temperate climate. You have been farming for over 20 years and have a good understanding of the growing cycles of your crops that have a narrow range of temperature tolerance. You have been keeping detailed records of your annual average temperature for the past decade. The graph below shows a clear trend in temperature change. Based on your knowledge of agriculture and environmental science, which of the following is the most likely impact of the observed temperature increase on your crops? A. Increased crop resilience and improved harvests. B. Reduced yield and delayed harvest C. Increased susceptibility to pests and diseases D. Optimal conditions for crop pollination and seed germination.

	c) B and C only		d) B, C and D only

Q.4	You are an environmental consultant hired by a local community to assess the potential environmental impacts of a proposed aquaculture farm.

Q.7	Consider the case study given below and answer the following question: Case Study: The Green Guardians of Greenhill High Greenhill High, a bustling school with over 1,000 students, faced a rising energy bill and growing concerns about its environmental impact. The principal and teachers knew they needed a change, and thus, the "Green Guardians" were born! This student-led initiative focused on three key areas: energy-efficient appliances, LED lighting, and well-insulation. Appliance Upgrade: The Green Guardians convinced the school board to replace ageing appliances with ENERGY STAR certified models. New washing machines used cold water effectively, while newer dishwashers boasted shorter cycles and automatic shut-offs. These changes resulted in a 20% reduction in kitchen and laundry energy consumption. Lighting the Way: Replacing traditional incandescent bulbs with LED lights was a game-changer. These LED bulbs lasted 25 times longer, used 80% less energy, and provided brighter, cooler light. Not only did the classrooms become more comfortable, but the school also saved 15% on its lighting costs. Insulating for Impact: The Green Guardians knew that keeping the school warm in winter and cool in summer would significantly reduce energy use. They proposed adding insulation to the attic and walls, sealing air leaks, and upgrading windows. The results showed a 10% drop in heating and cooling energy needs, creating a more comfortable and sustainable learning environment. The Green Guardians' efforts didn't stop there. They launched awareness campaigns, organised energy-saving competitions, and even convinced the cafeteria to source local, organic food. Their success story inspired other schools to join the green movement, proving that even small changes can make a big difference. Why is insulation in buildings crucial for reducing energy consumption?
	a) It directly generates electricity, lowering overall consumption.		b) It helps in regulating temperature, reducing the need for heating and cooling.
	c) It eliminates the need for appliances, thereby reducing energy usage.		d) It minimises lighting costs by reflecting natural light efficiently.

Q.8	An experiment is conducted to compare the efficiency of different rainwater harvesting systems in a specific location. System A uses rooftop collection, while System B utilises surface runoff collection. Which system is likely to yield more water in an area with infrequent but heavy rainfall?
	a) System A		b) System B
	c) Both systems will yield similar amounts of water		d) None of the systems will be effective in heavy rainfall conditions

Q.9	A region known for its dense forests undergoes significant deforestation due to increased logging activities and expansion of agricultural land. As a consequence, the landscape transforms from a lush forested area to large expanses of cleared land. How does the process of deforestation impact the water cycle in this scenario?
	a) Increases transpiration leading to higher rainfall and soil erosion.		b) Reduces transpiration, potentially leading to decreased rainfall and soil erosion.
	c) Enhances groundwater recharge due to lack of vegetation covering the ground.		d) Accelerates the water cycle, reducing the risk of floods

Q.10	Researchers conducted an experiment to assess the impact of ocean acidification on marine snail populations. They exposed snails to different pH levels in controlled environments and measured their growth rates over time. The graph below illustrates the relationship between pH levels, carbonate ion concentration. Based on this data, what is the probable outcome for marine snail populations as the H+ increases in the seawater?
	a) Snails will exhibit accelerated shell growth due to higher calcium carbonate availability.		b) Snails will exhibit reduced shell growth and vulnerability to shell dissolution.
	c) Snails will show no change in growth rates regardless of pH variations.		d) Snails will develop stronger, thicker shells to withstand changing pH conditions.
