Additional Practice Questions
Explain the difference between renewable and non-renewable resources.
mediumAnswer: Renewable resources are those that can be replenished naturally over time, such as sunlight, wind, and water. Non-renewable resources, on the other hand, are those that exist in limited quantities and cannot be replaced once depleted, such as fossil fuels and minerals.
Discuss the role of technology in resource development.
mediumAnswer: Technology plays a crucial role in resource development as it enables the transformation of natural substances into usable forms. With advancements in technology, we can extract resources more efficiently and use them in ways that were not possible before. For instance, the invention of machinery to extract iron from ore converted it into a usable resource.
Why is sustainable development necessary for future generations?
easyAnswer: Sustainable development is essential to ensure that the needs of the present do not compromise the ability of future generations to meet their own needs. It balances resource usage with conservation, maintaining ecological balance and preventing resource depletion.
List five human-made resources and explain how they depend on natural resources.
mediumAnswer: 1. Buildings: Depend on natural resources like stone, wood, and metals. 2. Vehicles: Require metals and fossil fuels. 3. Roads: Made from aggregates and bitumen derived from natural sources. 4. Electronics: Use minerals like silicon and copper. 5. Clothing: Fabrics may be derived from cotton plants or petroleum-based synthetic fibers.
What steps can individuals take to conserve resources in their daily lives?
easyAnswer: Individuals can conserve resources by recycling materials, reducing energy consumption, using public transport, adopting renewable energy sources like solar, conserving water, and supporting sustainable products.
