Answer:
Renewable resources | Non-Renewable resources |
Forests | Coal, natural gas, minerals |
Question 5. Why do we say that petroleum is a non-renewable resource?
Answer:
We say that petroleum is a non-renewable resource because it takes millions of years to form, and humans cannot make petroleum instantly once it is used.
Petroleum is made from dead plants and animals that got buried under the Earth for a very long time. When millions of years passed, the continuous effect of heat and pressure led to the formation of petroleum. After that, humans dug deep into the ground and took out the petroleum. But once this is used, we cannot make more in our entire life. For this reason, petroleum is considered a non-renewable resource.
Question 6. It is difficult to regrow forests. Justify this statement.
Answer:
Plants take several years to grow into trees and form forests. When forests are cut down because of human activities, it is not easy to bring back all the trees, plants, and animals that lived there. Without trees, the soil becomes dry, which leads to soil erosion. Due to this, new plants may not grow well on the same land. Also, the place where the forest has been removed can be used for buildings and roads, so there is no space left to plant new trees. That is why it is hard to regrow forests.
Question 7. Make a list of five daily activities in which you use natural resources. Suggest ways by which you can reduce their use.
Answer:
Five daily activities in which we use natural resources and how to reduce their use:
Brushing teeth – While we brush our teeth, we use water, which is a natural resource.
Way to reduce: Turn off the tap while brushing.
Traveling to school – Vehicles which we use to reach to school use petrol or diesel, which come from petroleum that is a natural resource.
Way to reduce: If the school is nearby, we can walk or cycle.
Using lights and fans – The Electricity that we use is either made from coal or water, and both are natural resources.
Way to reduce: Switch off lights and fans when not in use.
Eating food – Food comes from plants, animals, and water, which are all natural resources.
Way to reduce: Don’t waste food and take only what you can eat.
Using paper for homework – The Paper that we use for writing is prepared from trees.
Way to reduce: Both sides of the paper need to be used, and avoid wasting it.
Question 8. List four activities that are possible due to the presence of air.
Answer:
Four activities that are possible because of air:
Breathing – All living organisms need air for breathing and to stay alive..
Flying kites – Kites that we fly in the air are possible only due to the presence of air.
Sailing boats – Boats move forward into the water due to the air.
Burning fire – For burning fire, air is required. Without air, fire is not possible.
Question 9. How can you contribute toward enhancing the green cover of your locality? Make a list of actions to be taken.
Answer:
There are several steps that we can take to enhance the green cover around our locality, which are provided below:
1- Plant more trees in parks, gardens, and around our house.’
2- We need to stop cutting down plants and trees.
3- In our own home, on the balcony, we can grow some small plants.
4- Tree planting programs and drives can be promoted.
Question 10. In the given illustration, we see that food is being cooked. Answer the following questions—
(i) What type of energy is being used for cooking?
(ii) Name one benefit and one drawback of using this type of energy for cooking.
Answer:
(i) The above image is a woman standing beside a solar cooker. This solar cooker uses the energy from the sun to prepare a dish.
So, solar energy is the energy used for cooking.
(ii) Benefit: Solar cookers are eco-friendly and do not produce any smoke or harmful emissions, which is good for health as well as for the environment.
Drawback: This solar cooker is dependent on the sun. It can be used on cloudy or rainy days as well as at night.
Question 11. Cutting down trees on a large scale impacts the quality of the soil. Why do you think it is so?
Answer:
Cutting down trees on a large scale, known as deforestation, impacts the quality of soil to a large extent. Roots of the trees hold the soil together; when these trees are removed, the soil becomes loose and can be blown away by wind or water that causes the soil erosion. Also, without trees, the soil loses all its nutrients and becomes dry and less fertile, which decreases the growth of plants. That is why cutting down many trees makes the soil bad and weak.
Question 12. Explain two ways in which human activities pollute the air. Propose one action that can help in reducing air pollution.
Answer:
Two ways in which human activities pollute the air:
Smoke from vehicles such as cars, buses, and bikes releases harmful gases that lead to air pollution.
Burning waste and smoke from factories and industries release harmful gases into the atmosphere that cause air pollution.
Question 13. A family uses solar panels to generate electricity, a gas stove to cook food, and a windmill to pump water from a well. What would happen if there were no sunlight for a week?
Answer:
If there is no sunlight for a week, that family that uses solar panels to generate electricity would not get any electricity from the sun. They have to generate it by using different sources, like candles or batteries, for light.
But the gas stove will still work as usual, even though there is no sun, they can cook food.
The windmill will work if there is wind, and it can pump water from the well.
Question 14. Fill up the blanks using the following terms— (fossil fuels, forest, air, petroleum, coal, water and nonrenewable resource).
Answer:
Question 15. There is an increasing demand for trees to meet the requirements of industries and housing. Therefore, trees are being felled. Is it justified? Discuss and prepare a brief report.
Answer:
Given below is a brief report on Cutting Down Trees for Industries and Housing
Introduction:
Yes, there is an increasing demand for trees to meet the requirements of industries and housing. But, cutting of trees on a large scale will lead to the serious effects on environment.
Discussion:
There are some benefits and more problems due to deforestation, which are discussed below:
Benefits: Trees are cut down for wood to make furniture, paper, building materials, and many more things. The land after cutting of forests is then utilized for buildings and industries.
Problems: Cutting of trees leads to loss of various animal and plant species that are living in that forests. Apart from this, deforestation leads to soil erosion, increasing temperature, more air pollution, etc.
Conclusion:
Only the minimum amount of forests need to be cut, and to replace this loss, more and more plants should be planted by each and every person to reduce deforestation.
Question 16. Propose a plan to use less water in your school. What steps would you take to make this plan happen, and how would it help the environment?
Answer:
To use less water in school and to conserve that, various steps can be followed, which are listed below:
1- We need to make sure that all the taps are checked and fixed if they are leaking. Leaky taps will lead to a large amount of water.
2- All students and teachers need to ensure that all taps are tightly closed after use.
3- Schools can set up a system to collect rainwater, and this water can be used for watering plants and cleaning purposes.
4- Campaigns need to be conducted to teach students the importance of water and how to save it.
How It Helps the Environment:
1- If we save water, it will be useful for future generations.
2- By conserving water, we can help maintain the balance of the ecosystem and all the processes that require water.
The students can begin by carefully reading the chapter to understand the importance of natural resources and biodiversity. They should make notes of key concepts such as renewable and non-renewable sources, conservation, and examples of flora and fauna. They can use diagrams and flow charts to have a visual memory of the chapter. They can practice the exercise questions and try answering them in their own words. Finally, they can refer to the NCERT Solutions of Class 6 to relate the concepts to real-life examples, which makes their learning easier and more practical.

Natural resources are materials provided by nature that are essential for the survival of all living beings. Examples include air, water, sunlight, soil, forests, minerals, and fossil fuels.
Natural resources are classified as:
Renewable resources: Replenished naturally, like air, water, and forests.
Non-renewable resources: Limited in quantity and not quickly replenished, like fossil fuels and minerals.
Conserving natural resources is crucial to ensure their availability for future generations, maintain ecological balance, and prevent environmental degradation.
Yes, for example, fallen leaves decay and enrich the soil with nutrients, which are then used by new plants. This is an example of recycling in nature, showing how resources are reused and replenished naturally.
