Study notes focus
In the vibrant village of Green Valley, a curious student named Riya embarks on a walk with her wise grandfather to understand the essence of natural resources. The chapter "Natural Resources and Their Use" introduces students to the classification of resources into biotic and abiotic, renewable and non-renewable, and their sustainable use. As Riya learns about the impact of over-exploitation and the importance of conservation, this chapter becomes a vital guide for Class 8 students. Harshali Academy brings this engaging lesson alive, making it easier for students to grasp complex concepts and for parents and teachers to evaluate and teach effectively. These notes are built for students who want a readable explanation first and a listening path next for Class 8 Social Science.
Important exam questions with answers
What are natural resources? Explain their classification based on origin.
Natural resources are materials found in nature that are useful to humans, such as air, water, soil, plants, and minerals. They are classified based on origin into biotic (living things like plants and animals) and abiotic (non-living things like water, air, and minerals).
Describe the difference between renewable and non-renewable resources with examples.
Renewable resources can be replenished naturally and used repeatedly, such as sunlight and wind. Non-renewable resources, like coal and petroleum, take millions of years to form and cannot be replaced once used up.
What are the consequences of over-exploitation of natural resources?
Over-exploitation leads to environmental degradation, loss of biodiversity, soil erosion, water scarcity, pollution, and climate change. It also threatens the availability of resources for future generations.
