Introduction to CBSE Class 10 Social Science Geography Chapter "Minerals and Energy Resources"
“Minerals and Energy Resources” is a comprehensive chapter that begins with an explanation of what minerals are and how they are different from rocks. It discusses various types of minerals, such as metallic, non-metallic, and energy minerals, and their distribution across the globe and in India.
The chapter delves into the methods of mineral extraction and the environmental impacts of mining. Students will explore the significance of conservation of minerals as a sustainable practice, considering their non-renewable nature. The narrative then shifts to the various sources of energy, both conventional and non-conventional, such as coal, petroleum, natural gas, solar, wind, nuclear, and hydroelectric power.
Emphasis is placed on the shift towards renewable energy sources due to the finite supply of fossil fuels and the environmental concerns associated with their use. The chapter concludes with case studies of regions rich in minerals and energy resources and discusses the economic, environmental, and political implications of resource distribution.

Questions and Answers for CBSE Class 10 Social Science Geography Chapter "Minerals and Energy Resources"
- Q1: What are minerals, and how are they categorized?
ANS: Minerals are naturally occurring substances with a definite chemical composition. They are categorized as metallic, non-metallic, and energy minerals based on their properties and uses. - Q2: Why is mining important for a country’s economy?
ANS: Mining is important as it provides raw materials for industries, generates employment, and contributes to foreign exchange earnings, thereby boosting a country’s economy. - Q3: What is the difference between conventional and non-conventional energy resources?
ANS: Conventional energy resources are those that have been traditionally used and are non-renewable, like coal and petroleum. Non-conventional energy resources are renewable and more environmentally friendly, like solar and wind energy. - Q4: How can we conserve mineral resources?
ANS: We can conserve mineral resources by using them judiciously, recycling, and adopting sustainable mining practices. - Q5: What are the environmental impacts of mineral extraction?
ANS: Mineral extraction can lead to land degradation, deforestation, soil erosion, loss of biodiversity, and pollution of air and water bodies. - Q6: Why is there a shift towards renewable energy sources?
ANS: The shift towards renewable energy sources is driven by the need to reduce dependence on depleting fossil fuels and to mitigate environmental issues like climate change. - Q7: What role does the government play in managing energy resources?
ANS: The government plays a role in managing energy resources by formulating policies for exploration, production, distribution, and promoting research in sustainable technologies. - Q8: What is sustainable development in the context of mineral and energy resources?
ANS: Sustainable development means using mineral and energy resources in a way that meets the needs of the present without compromising the ability of future generations to meet their own needs. - Q9: How do minerals affect the geopolitics of a region?
ANS: Minerals can affect the geopolitics of a region by influencing trade relationships, causing conflicts over resource control, and impacting economic stability. - Q10: What is the significance of solar energy in today’s world?
ANS: Solar energy is significant as it provides a clean, inexhaustible source of power that can reduce greenhouse
