I. Chapter Summary

This chapter discusses the classification, distribution, conservation, and uses of minerals and energy resources in India. It explains the types of minerals (metallic and non-metallic), mode of occurrence, mining methods, and the significance of energy resources—both conventional (coal, petroleum, natural gas) and non-conventional (solar, wind, geothermal, etc.). It also touches upon the environmental consequences of overexploitation and the need for sustainable resource management.

II. Key Concepts Covered

Concept	Explanation
Minerals	Naturally occurring substances with a definite chemical composition.
Types of Minerals	Metallic (ferrous & non-ferrous) and Non-metallic minerals.
Mode of Occurrence	Found in veins, beds, sedimentary rocks, or as placer deposits.
Mining	Open-cast and shaft mining methods; environmental effects.
Conservation of Minerals	Sustainable use, recycling, and substitution.
Energy Resources	Divided into conventional (coal, oil) and non-conventional (solar, wind).
Importance of Energy	Essential for industries, agriculture, and domestic use.
Conservation of Energy	Need for efficiency, renewable sources, and future sustainability.

Exam Preparation:

• Revise NCERT diagrams and tables (e.g., types of energy resources).
• Solve PYQs and sample papers weekly.
• Use mind maps for classification-based topics.

Stress Management:

• Practice mindfulness or 5-min breathing exercises.
• Stay physically active (walks, stretching).
• Break large topics into smaller, manageable chunks.
