Question 1: Explain the concept of renewable and non-renewable resources. Provide two examples of each.

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

Question 2: Describe how urbanization can lead to increased demand for water resources in a city.

Answer: Urbanization increases the population density in cities, leading to higher water consumption for domestic, industrial, and recreational purposes. This can strain existing water supplies and cause shortages.

Question 3: Identify and explain two methods used in resource management to ensure sustainable use of water.

Answer: Methods include water recycling, which reuses wastewater for irrigation or industrial processes, and rainwater harvesting, which collects and stores rainwater for later use, reducing dependence on groundwater.

Question 4: Discuss the environmental and social impacts of overfishing on marine resources.

Answer: Overfishing depletes fish populations, disrupting marine ecosystems and reducing biodiversity. It also affects fishing communities economically and can lead to the collapse of local fisheries.

Question 5: Draw a simple diagram of a water cycle, labeling all key stages involved.

Answer: A correct diagram would show evaporation from a water body, condensation forming clouds, precipitation returning water to the ground, collection in rivers and lakes, and runoff returning to the water body.

Question 6: Explain the term 'resource depletion' and give an example related to fossil fuels.

Answer: Resource depletion refers to the consumption of resources faster than they can be replenished, leading to scarcity. An example is the overuse of coal, which is a non-renewable fossil fuel, leading to its eventual exhaustion.

Question 7: Describe two ways in which technology can help in managing natural resources more sustainably.

Answer: Technology such as satellite imaging helps monitor resource use and environmental changes, aiding better management. Additionally, advances in renewable energy technology reduce reliance on finite resources like coal and oil.

Question 8: Sketch a diagram illustrating the concept of sustainable resource management. Include key components such as monitoring, conservation, and renewable resources.

Answer: A correct sketch would include interconnected elements like a monitoring station, renewable resource icons (solar panel, wind turbine), conservation practices (recycling bins, protected areas), illustrating a cycle of sustainable management.

Question 9: Evaluate the advantages and disadvantages of relying on renewable energy sources in resource management.

Answer: Advantages include reduced pollution, sustainability, and lower long-term costs. Disadvantages include high initial investment, intermittent supply (e.g., sunlight, wind), and current technological limitations.

Question 10: Identify one global challenge related to resource management and propose a possible solution.

Answer: Challenge: Water scarcity in arid regions. Solution: Implementing large-scale water conservation measures and developing desalination plants to increase freshwater supply.
