Question 1: Explain the difference between renewable and non-renewable resources, providing two examples of each.

Answer: Renewable resources are natural resources that can be replenished naturally over time, such as solar energy and wind power. Non-renewable resources are finite and cannot be replenished once used, such as coal and oil.

Question 2: Describe two methods used to manage water resources sustainably in a region experiencing water scarcity.

Answer: Methods include implementing water conservation measures (like fixing leaks and using water-efficient appliances) and developing alternative sources such as rainwater harvesting or desalination.

Question 3: Identify and explain one advantage and one disadvantage of exploiting non-renewable resources.

Answer: Advantage: Non-renewable resources like oil provide a large amount of energy and economic benefits. Disadvantage: Once depleted, they cannot be replaced, leading to resource exhaustion and environmental damage.

Question 4: Discuss how recycling can help conserve natural resources. Provide two specific examples.

Answer: Recycling reduces the need to extract raw materials from the environment, conserving resources. Examples include recycling paper to save trees and recycling metals to reduce mining activities.

Question 5: Explain the concept of sustainable resource management and why it is important for future generations.

Answer: Sustainable resource management involves using resources in a way that meets current needs without compromising the ability of future generations to meet theirs. It ensures long-term environmental health and resource availability.

Question 6: Describe a policy or regulation that a government might implement to promote renewable energy use in a country.

Answer: A government might offer tax incentives or subsidies to individuals and companies that install solar panels or wind turbines, encouraging the adoption of renewable energy sources.

Question 7: Sketch a simple diagram illustrating the water cycle, including at least three key processes.

Answer: A correct sketch would show evaporation from a water body, condensation forming clouds, and precipitation returning water to the ground, with arrows indicating movement.

Question 8: Identify one challenge associated with the global extraction of non-renewable resources and suggest a potential solution.

Answer: Challenge: Environmental degradation from mining activities. Solution: Implement stricter environmental regulations and promote recycling and alternative energy sources.

Question 9: Evaluate the impact of excessive resource exploitation on local ecosystems and communities.

Answer: Excessive exploitation can lead to habitat destruction, pollution, and loss of biodiversity, which negatively affects local wildlife and can also harm communities through health issues and resource depletion.

Question 10: Draw a plan diagram showing how solar panels convert sunlight into usable electricity. Label the main components involved.

Answer: A correct sketch would include solar panels capturing sunlight, arrows indicating energy flow to a battery or inverter, and labels for each component such as 'solar panel,' 'inverter,' and 'battery.'
