Q.1	During a school project on recycling, Emma was tasked with investigating the environmental benefits of recycling aluminium cans versus manufacturing new ones. Which of the following statements is true regarding this comparison? 1. Recycling aluminium cans saves energy but does not reduce pollution. 2. Manufacturing new aluminium cans consumes less energy than recycling them. 3. Recycling aluminium cans reduces energy consumption and environmental pollution. 4. Manufacturing new aluminium cans have no impact on energy consumption or pollution.
	a) Only 1		b) Only 2
	c) Only 3		d) Both 1 and 4

Q.2	Among the listed pollutants, which specific element poses the most significant risk to global water quality, often contributing to detrimental algal blooms?
	a) Nitrogen and phosphorous compounds		b) Substances with substantial density
	c) Disease-causing microorganisms		d) Hydrocarbon-based substances

Q.3	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.4	The government of a city wants to switch to renewable energy sources to help the environment. Which of the following strategies could the city use to promote renewable energy adoption and reduce environmental impact?
	a) Implementing tax incentives for solar energy installations		b) Developing new coal mining projects to boost energy production
	c) Encouraging the use of gasoline-powered vehicles		d) Cutting down more trees to make space for wind farms

Q.5	A group of students in a science class is conducting an experiment to demonstrate the heat-trapping properties of greenhouse gases for a school project. They want to create a compelling demonstration. Which experimental approach should they choose?
	a) Burning fossil fuels in an open space		b) Comparing the absorption of infrared radiation by different gases
	c) Measuring surface air temperatures		d) Monitoring ocean currents

Q.6	During an Earth Science field trip, students are exploring the impact of rising temperatures on the local ecosystem. The students notice a decline in the population of a particular plant species in the area compared to previous years. Which factor related to climate change is most likely influencing this decline?
	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.7	Nick installed a solar panel system on his rooftop to harness solar energy for his home. He wants to understand the practical process behind solar energy generation. Help him understand what happens when photons from sunlight strike the photovoltaic cells in a solar panel system.
	a) They generate heat energy for space heating.		b) They release electrons, creating an electric current to power appliances.

	a) Land clearing for agricultural purposes		b) Fertiliser use
	c) Livestock production		d) Irrigation practices

Q.9	A group of scientists is studying the effects of climate change on a mountain grassland ecosystem. They observe that the average temperature in the region has increased over the past few decades, and that the timing of plant flowering has shifted earlier in the spring. How might these changes impact the interactions between plants and pollinators in this ecosystem?
	a) Pollinators may have difficulty finding food sources due to the mismatch between their life cycle and the timing of plant flowering, also resulting in reduced pollination success.		b) Pollinators may benefit from the increased temperature, as it could lead to an increase in plant growth and nectar production.
	c) Earlier plant flowering may have no significant impact on pollinators as they can adapt their behaviour and life cycles accordingly.		d) The rise in temperature could decrease the number of plant species, thereby reducing the variety of resources available for pollinators, causing a decline in their populations.

	a) A temperate deciduous forest with distinct seasonal variations.		b) A vast and diverse tropical rainforest with abundant rainfall.
