Question 1: Define the term 'renewable resource' and give two examples commonly used by humans.

Answer: A renewable resource is a natural resource that can be replenished naturally at a rate comparable to its consumption. Examples include solar energy and wind energy.

Question 2: Explain one advantage and one disadvantage of using fossil fuels as a primary energy source.

Answer: Advantage: Fossil fuels provide a large amount of energy and are currently widely available. Disadvantage: They release greenhouse gases contributing to climate change.

Question 3: Describe how water scarcity can affect a country's population and economy.

Answer: Water scarcity can lead to health problems, reduce agricultural productivity, and limit industrial growth, ultimately harming the country's economy and quality of life.

Question 4: Identify three ways in which humans have increased the availability of resources in urban areas.

Answer: Building infrastructure such as dams for water supply, importing resources from other regions, and recycling materials to extend resource use.

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

Answer: Sustainable resource management involves using resources in a way that meets current needs without compromising future availability. It is important to ensure resources are available for future generations and to prevent environmental degradation.

Question 6: Draw a simple diagram of a water cycle including the processes of evaporation, condensation, and precipitation. Label each part clearly.

Answer: A diagram showing water evaporating from a body of water, forming clouds through condensation, and falling as rain or snow as precipitation.

Question 7: Describe one method that farmers in arid regions use to conserve water for irrigation.

Answer: Farmers use drip irrigation systems, which deliver water directly to the roots of plants, reducing waste and evaporation.

Question 8: Discuss the impact of overfishing on marine resources and what measures can be taken to prevent it.

Answer: Overfishing leads to the depletion of fish stocks, disrupting marine ecosystems. Measures include setting fishing quotas, establishing marine protected areas, and regulating fishing seasons.

Question 9: Explain how recycling helps in resource management and give an example of a recyclable material.

Answer: Recycling reduces the need to extract and process raw materials, conserving natural resources and energy. An example is recycling aluminum cans.
