Q.1	In your research on marine ecosystems, you've found evidence suggesting shifts in the distribution of certain fish species. Fish that were once abundant in cooler waters are now migrating to different regions. What is the primary factor influencing this phenomenon?
	a) Changes in ocean salinity		b) Reduced predation in the new habitats
	c) Increasing acidity in the oceans		d) Rising ocean temperatures

Q.2	Max was studying the Earth's atmosphere in class. He learned about a special layer that shields us from harmful solar radiation. While explaining it to his friend, Sarah, she asked, "What's the name of this protective layer?"
	a) Ionosphere		b) Exosphere
	c) Troposphere		d) Stratosphere

Q.3	In a remote village, access to electricity is limited. The government aims to introduce affordable and clean energy sources to improve living conditions. Considering the village's geographical isolation, unreliable grid connections, and the need for sustainable solutions, which approach would be the most effective and practical for providing immediate access to clean energy?
	a) Establishing a small-scale wind turbine farm to harness local wind resources.		b) Implementing solar microgrids tailored to the village's energy needs.
	c) Introducing biogas digesters to convert organic waste into usable energy.		d) Installing small-scale hydroelectric systems using nearby streams or rivers.

Q.4	A farmer observed that the soil in his fields was becoming increasingly dry, even after heavy rainfall. The farmer suspected that the dry soil was due to increased runoff, preventing water from infiltrating the ground. Which of the following practices could help the farmer improve soil moisture? A. Tilling the soil to increase its water-holding capacity B. Planting cover crops to protect the soil from erosion C. Creating channels and other structures to slow down runoff
	a) A only		b) A and B only
	c) B and C only		d) A, B and C

Q.5	Sarah is a teacher at an elementary school. She collects scrap paper from her students and uses the blank sides for drawing, thereby extending the life of the paper before recycling it. What is Sarah doing in this scenario to contribute to waste reduction and sustainability?
	a) Throwing scrap paper away		b) Promoting the use of new paper
	c) Reusing paper before recycling it		d) Increasing paper waste

Q.6	The Johnson family wants to reduce food waste at home. They usually end up throwing away a considerable amount of food each week. They decide to implement changes to address this issue. Which action would be the most effective for the Johnson family to reduce food waste at home?
	a) Buying groceries in large quantities to minimise shopping trips		b) Planning meals in advance based on a weekly menu and creating a shopping list
	c) Storing all food items in the refrigerator to prolong their shelf life		d) Discarding leftovers promptly after meals to prevent spoilage

Q.7	During an Earth Science field trip, students are exploring the impact of rising temperatures on the local ecosystem.

	a) Reduced levels of precipitation and increased drought conditions.		b) Increased availability of nutrients in the soil.
	c) Decreased levels of carbon dioxide in the atmosphere.		d) Rising sea levels affecting the soil composition.

Q.8	A school implemented water-saving methods, reducing daily usage by 15%. If the school previously consumed 500 liters of water per day, what is the new daily consumption after applying these strategies?
	a) 425 liters		b) 575 liters
	c) 75 liters		d) 4250 liters

Q.9	In a coastal city, students investigated the impact of nutrient runoff on marine ecosystems. They discovered that agricultural practices contributed to excess nutrients reaching the ocean. How do nutrient runoff and eutrophication affect marine life?

	c) Eutrophication leads to increased oxygen levels, supporting marine species.		d) Introducing more fishing activities can balance the effects of nutrient runoff.

Q.10	In the following question, you will find an assertion and a reason. Select the appropriate option that applies. Assertion: While deserts like the Sahara are notoriously arid, some coastal regions also experience water scarcity. Reason: Rising sea levels due to climate change can contaminate freshwater sources with saltwater intrusion.
	a) Both assertion and reason are true, and the reason is the correct explanation of the assertion.		b) Both assertion and reason are true, but the reason is not the correct explanation of the assertion.
	c) The assertion is true, but the reason is false.		d) The assertion is false, but the reason is true.
