Natural Resources and Their Use Class 8 PPT Free Download

Class 8 Social Science Chapter 1 – Natural Resources and Their Use

Everything we use every day — the water we drink, the air we breathe, the fuel that runs vehicles, and the soil that grows our food — comes from nature. In this chapter, "Natural Resources and Their Use," Class 8 CBSE Social Science (Geography) students learn what natural resources are, how they are classified, and why using them wisely through conservation and sustainable development is essential for the future. This free PPT and notes download covers the complete NCERT 2026–27 syllabus in a simple, exam-focused format so you can revise quickly before tests.

What are Natural Resources?

Natural resources are all the materials and substances that occur naturally in the environment and are useful to humans, such as land, water, air, minerals, forests, and sunlight. These resources form the basis of human survival and economic activities, and their availability and use vary greatly from one region to another based on climate, geography, and level of development.

Renewable and Non-Renewable Resources

Based on how quickly they can be replenished, natural resources are classified into two main categories.

• Renewable resources: Resources that can be replenished naturally within a short period of time, such as sunlight, wind, water, and forests. These do not get exhausted with continuous use if managed carefully.
• Non-renewable resources: Resources that take millions of years to form and cannot be replenished within a human lifetime, such as coal, petroleum, and minerals. Once used up, these resources cannot be quickly replaced.

Biotic and Abiotic Resources

Natural resources can also be classified based on their origin, that is, whether they come from living or non-living things.

• Biotic resources: Resources obtained from living organisms, such as forests, animals, fish, and other organic matter.
• Abiotic resources: Resources obtained from non-living things, such as land, water, air, and minerals.

Classification by Distribution and Level of Development

Natural resources are further classified based on how widely they are distributed and how much they have been used or developed.

• Ubiquitous resources: Resources found almost everywhere, such as air and sunlight.
• Localised resources: Resources found only in certain regions, such as specific minerals found only in particular areas.
• Potential resources: Resources found in a region but not yet fully surveyed or used.
• Developed resources: Resources that have been surveyed and are being used with the help of technology.

Conservation and Sustainable Development

Since many natural resources, especially non-renewable ones, are limited in supply, they must be used carefully to ensure they remain available for future generations. Conservation means the careful and planned use of natural resources to avoid wastage and depletion. Sustainable development is the idea of using resources in a way that meets the needs of the present generation without compromising the ability of future generations to meet their own needs. Overuse and exploitation of resources can lead to serious problems such as depletion, pollution, and environmental damage.

Renewable vs Non-Renewable Resources

Real-Life Applications

Understanding natural resources helps us make responsible choices in daily life, such as saving water, using energy-efficient appliances, and switching to renewable energy sources like solar panels and wind power. Governments use the classification of resources to plan mining, agriculture, and conservation policies, while industries rely on knowledge of resource availability to plan sustainable production. Awareness of resource conservation also drives everyday habits like recycling paper and plastic, carpooling to save fuel, and planting trees to protect biotic resources for future generations.

Frequently Asked Questions

Q1. What is the difference between renewable and non-renewable resources?
Renewable resources can be replenished naturally within a short time, such as sunlight and water, while non-renewable resources take millions of years to form and are limited in supply, such as coal and petroleum.

Q2. What is the difference between biotic and abiotic resources?
Biotic resources are obtained from living organisms, such as forests and animals, while abiotic resources are obtained from non-living things, such as land, water, and minerals.

Q3. What is meant by conservation of resources?
Conservation of resources means using natural resources carefully and in a planned manner to avoid wastage and depletion, ensuring they remain available for future generations.

Q4. What is sustainable development?
Sustainable development means using natural resources in a way that meets the needs of the present generation without compromising the ability of future generations to meet their own needs.

Q5. Why are non-renewable resources considered more valuable to conserve?
Non-renewable resources are more valuable to conserve because they take millions of years to form and cannot be replaced once they are used up, unlike renewable resources.
