How do humans use natural resources for materials? (1) c. Explain how natural resources are categorized based on their uses. (2) 44. Read the following text carefully and answer the questions that follow: Natural resources can be renewable or non-renewable. Renewable resources, like sunlight, rivers, forests, and soil, follow Nature’s principle of restoration and regeneration if managed sustainably. Disturbing these cycles through deforestation, industrialisation, or overfishing leads to depletion. Non-renewable resources, such as coal, petroleum, and minerals, take millions of years to form and cannot be replenished quickly. India has large coal reserves, but they may last only about 50 years, highlighting the need for judicious use. Questions: a. What makes a resource renewable? (1) b. Why are fossil fuels called non-renewable resources? (1) c. Explain how human actions disturb the renewable cycle of Nature. (2) [4]
