Chapter Overview
- Minerals: Naturally occurring substances with definite chemical composition.
- Energy Resources: Conventional (coal, petroleum, natural gas) and Non-conventional (solar, wind, nuclear).
- Distribution: Minerals are unevenly distributed across India.
- Conservation: Necessary because minerals are exhaustible resources.
Types of Minerals
1. Metallic Minerals
Metallic minerals contain metals in raw form.
Examples:
- Iron ore
- Copper
- Bauxite
- Manganese
2. Non-Metallic Minerals
These minerals do not contain metals.
Examples:
- Mica
- Limestone
- Gypsum
3. Energy Minerals
These minerals are used for producing power and energy.
Examples:
- Coal
- Petroleum
- Natural Gas
Energy Resources
Conventional Energy Resources
- Coal
- Petroleum
- Natural Gas
- Electricity
These resources are widely used but are exhaustible and polluting.
Non-Conventional Energy Resources
- Solar Energy
- Wind Energy
- Tidal Energy
- Biogas
- Nuclear Energy
These resources are renewable and eco-friendly.
Distribution of Minerals in India
| Mineral | Major Producing States |
|---|---|
| Iron Ore | Odisha, Jharkhand, Chhattisgarh, Karnataka |
| Bauxite | Odisha, Gujarat, Jharkhand, Maharashtra |
| Mica | Jharkhand, Bihar, Andhra Pradesh |
| Coal | Jharkhand, West Bengal, Odisha |
| Petroleum | Assam, Gujarat, Mumbai High |
Importance of Minerals and Energy Resources
