• (a) Oxygen
• (b) Rainwater harvesting
• (c) The Sun
• (d) Fossil fuels
• (e) Renewable resources

Explanation: These are important scientific terms introduced in the chapter and form the basis for understanding natural resources.

Question 2. Why is air considered an essential natural resource?

Answer:

Air is essential because it contains oxygen required for respiration. Plants also use carbon dioxide from the air to prepare food through photosynthesis. Air supports life, helps in burning, and plays an important role in weather and climate.

Question 3. Why should we conserve water?

Answer:

Only a small portion of Earth's water is available as freshwater for human use. Water is needed for drinking, cooking, farming, industries, and sanitation. Conserving water ensures that enough freshwater remains available for present and future generations.

Question 4. Mention any four methods of saving water.

Answer:

• Turn off taps when not in use.
• Repair leaking taps and pipes.
• Practice rainwater harvesting.
• Reuse water whenever possible.

Question 5. Why is the Sun called the ultimate source of energy?

Answer:

Plants prepare food using sunlight through photosynthesis. Animals depend on plants either directly or indirectly for food. Solar energy is also used to generate electricity and heat. Therefore, almost all life on Earth ultimately depends on the Sun.

Question 6. State any four benefits of forests.

Answer:

• Provide oxygen.
• Offer food and shelter to wildlife.
• Prevent soil erosion.
• Help maintain ecological balance and biodiversity.

Question 7. Why are forests called the natural home of wildlife?

Answer:

Forests provide food, water, shelter, and suitable living conditions for a wide variety of animals, birds, insects, and microorganisms. Therefore, they are considered the natural habitat of wildlife.

Question 8. Explain how soil is formed.

Answer:

Soil forms over thousands of years through the weathering of rocks caused by wind, water, heat, and living organisms. Decayed plants and animals mix with rock particles to make fertile soil.

Question 9. What are minerals?

Answer:

Minerals are naturally occurring substances found in rocks. They provide valuable metals such as iron, copper, aluminium, and gold, which are used to manufacture many useful products.

Question 10. What are fossil fuels?

Answer:

Fossil fuels are natural fuels such as coal, petroleum, and natural gas that were formed from the remains of ancient plants and animals over millions of years.

Question 11. Differentiate between renewable and non-renewable resources.

Answer:

Question 12. Why should fossil fuels be used carefully?

Answer:

Fossil fuels take millions of years to form and cannot be replaced quickly. Their excessive use also causes air pollution and contributes to global warming. Therefore, they should be used wisely and alternative energy sources should be encouraged.

Question 13. Explain the importance of rainwater harvesting.

Answer:

Rainwater harvesting collects and stores rainwater for future use. It helps recharge groundwater, reduces water shortage, prevents wastage of rainwater, and supports sustainable water management.

Question 14. How do forests help in maintaining environmental balance?

Answer:

Forests absorb carbon dioxide, release oxygen, regulate climate, prevent floods and soil erosion, conserve biodiversity, and maintain the water cycle. Thus, they play a vital role in protecting the environment.

Question 15. Write any five ways by which we can conserve natural resources.

Answer:

• Plant more trees.
• Save electricity.
• Use water carefully.
• Reduce, Reuse and Recycle materials.
• Use renewable sources of energy whenever possible.

Question 16. Explain why every citizen should protect nature's treasures.

Answer:

Nature's treasures support all forms of life. If these resources are overused or polluted, future generations may face shortages of food, water, clean air, and energy. Protecting natural resources helps maintain ecological balance and ensures sustainable development.
