Two Mark Questions

Question 1. Why are natural resources called nature's treasures?

Answer: Natural resources provide food, water, air, energy, and raw materials essential for life. Since they are valuable and support all living organisms, they are called nature's treasures.

Question 2. Differentiate between renewable and non-renewable resources.

Answer:

Question 3. Write any two uses of forests.

Answer:

• Forests provide oxygen.
• They provide shelter to wildlife.

Question 4. Why should we conserve water?

Answer: Freshwater is limited. Conserving water ensures that enough clean water remains available for present and future generations.

Question 5. Mention any two uses of rocks and minerals.

Answer:

• Construction of buildings and roads.
• Manufacturing machines, vehicles, and household items.

Three Mark Questions

Question 1. Explain the importance of air.

Answer:

Air contains oxygen needed for respiration and carbon dioxide required for photosynthesis. It also helps in burning, supports weather changes, and provides wind energy for generating electricity.

Question 2. Describe any three methods of conserving water.

Answer:

• Practice rainwater harvesting.
• Repair leaking taps and pipelines.
• Reuse water whenever possible.

Question 3. Explain the importance of forests.

Answer:

Forests provide oxygen, conserve biodiversity, prevent soil erosion, regulate rainfall, absorb carbon dioxide, and provide food, medicines, timber, and shelter to many living organisms.

Question 4. Why should fossil fuels be used carefully?

Answer:

Fossil fuels are limited in quantity and take millions of years to form. Their excessive use causes air pollution and contributes to global warming. Therefore, they should be used wisely.

Question 5. Explain how soil is important for living organisms.

Answer:

Soil provides nutrients, water, and support to plants. It is also home to many organisms and forms the foundation of agriculture, which supplies food to humans and animals.

Long Answer Questions

Question 1. Explain the importance of natural resources in our daily life.

Answer:

Natural resources are essential for human survival and development. Air supports respiration, water is required for drinking and agriculture, sunlight provides energy, forests maintain ecological balance, soil supports crop production, rocks and minerals provide raw materials, and fossil fuels supply energy for transportation and industries. Proper use of these resources ensures sustainable development.

Question 2. Discuss the importance of conserving natural resources.

Answer:

Conservation of natural resources ensures that future generations have access to clean air, water, fertile soil, forests, and energy resources. It reduces pollution, protects biodiversity, prevents resource depletion, and supports sustainable development. Every individual should use resources responsibly and avoid unnecessary wastage.

Question 3. Explain the differences between renewable and non-renewable resources with suitable examples.

Answer:

Renewable resources can be replenished naturally within a relatively short time. Examples include sunlight, wind, and water. Non-renewable resources take millions of years to form and are available in limited quantities. Examples include coal, petroleum, natural gas, and minerals. Renewable resources should be preferred whenever possible to reduce environmental damage.

Question 4. Describe the importance of forests and suggest measures for their conservation.

Answer:

Forests provide oxygen, regulate climate, conserve biodiversity, prevent floods and soil erosion, and supply food, medicines, and timber. Forest conservation can be achieved through afforestation, preventing illegal cutting of trees, controlling forest fires, reducing deforestation, and encouraging community participation in tree plantation programmes.

Question 5. Explain how every citizen can help protect nature's treasures.

Answer:

Every citizen can protect nature by saving water and electricity, planting trees, reducing pollution, recycling materials, avoiding unnecessary use of fossil fuels, protecting wildlife, and spreading awareness about environmental conservation. Small individual efforts together create a significant positive impact on the environment.
