FAQs on Class 9 Science Previous Year Questions - Natural Resources (Used only for Project Work)

1. What are natural resources?
Ans. Natural resources are materials or substances that occur naturally in the environment and are used by humans to meet their needs. These resources can be categorized into renewable resources, such as sunlight and wind, which are naturally replenished, and non-renewable resources, such as fossil fuels, which are limited in quantity and cannot be easily replenished.
2. What are some examples of renewable natural resources?
Ans. Examples of renewable natural resources include sunlight, wind, water, timber, and biomass. These resources have the ability to replenish themselves over time and can be utilized without depleting their availability for future generations.
3. What are some examples of non-renewable natural resources?
Ans. Non-renewable natural resources are limited in quantity and cannot be easily replenished. Examples of non-renewable resources include fossil fuels (coal, oil, natural gas), minerals (iron, copper, gold), and nuclear energy sources (uranium). Once these resources are depleted, they cannot be replaced within a human lifespan.
4. Why is it important to conserve natural resources?
Ans. Conserving natural resources is crucial for sustainable development and the well-being of future generations. By preserving and efficiently using natural resources, we can reduce environmental degradation, prevent resource depletion, and ensure the availability of essential materials for various human needs, including food, shelter, and energy.
5. How can we conserve natural resources in our daily lives?
Ans. There are several ways individuals can contribute to the conservation of natural resources in their daily lives. Some examples include practicing energy efficiency by turning off lights and appliances when not in use, reducing water consumption, recycling and reusing materials, supporting sustainable agriculture and forestry practices, and choosing environmentally-friendly transportation options like walking, cycling, or using public transport. These small actions can collectively make a significant impact on the preservation of natural resources.
