Class 12 Geography - ODISHA
Mineral and Energy Resources
The chapter 'Mineral and Energy Resources' in Class 12 Geography under the Odisha BSE board explores the distribution, classification, and economic significance of various mineral and power resources in India and Odisha. Students will study metallic minerals like iron ore, bauxite, and manganese, non-metallic minerals, and conventional as well as non-conventional sources of energy like coal, petroleum, solar, and wind energy. This chapter is vital for board exams as it tests both factual map-based knowledge and analytical skills regarding sustainable resource utilization, industrial location factors, and the contribution of mineral wealth to the state and national economy.

Metallic Minerals
Minerals that contain metallic elements and provide raw materials for metallurgical and engineering industries, such as iron ore, bauxite, and copper.
Non-Metallic Minerals
Minerals that do not contain extractable metals, including limestone, mica, and dolomite, which are crucial for cement and chemical industries.
Conventional Energy Sources
Traditional, non-renewable sources of energy that have been used for a long time, such as coal, petroleum, natural gas, and hydel power.
Non-Conventional Energy Sources
Renewable and clean sources of energy like solar, wind, biomass, and tidal energy that are gaining importance due to environmental concerns.
Mineral Belts in India
Major geographical concentrations of minerals, such as the Chota Nagpur plateau region and the Odisha-Jharkhand mineral belt.

Frequently Asked Questions
Which mineral has the highest concentration in Odisha?
Odisha is famously rich in iron ore, bauxite, manganese, and coal, holding a major share of India's total bauxite and iron ore reserves.
What is the difference between metallic and non-metallic minerals?
Metallic minerals yield metals when melted (e.g., iron, copper) and are hard and lustrous, whereas non-metallic minerals do not yield new metals and lack metallic shine (e.g., limestone, mica).
Why are non-conventional energy sources becoming more important?
They are renewable, eco-friendly, inexhaustible, and help reduce dependence on depleting fossil fuels while combating global warming.
