Metallic Minerals
Minerals that are sources of metals, such as iron ore, bauxite, and manganese, which form the base for metallurgical industries.
Non-Metallic Minerals
Minerals that do not yield new metals, including mica, limestone, and dolomite, widely used in cement, electrical, and chemical industries.
Conventional Energy Sources
Traditional, exhaustible sources of energy like coal, petroleum, natural gas, and electricity (thermal and hydroelectric) that have been in use for a long time.
Non-Conventional Energy Sources
Renewable and eco-friendly sources of energy such as solar, wind, biomass, geothermal, and tidal energy that are gaining importance for sustainable development.
Conservation of Resources
The careful, planned, and sustainable use of finite mineral and energy resources to prevent depletion and reduce environmental degradation.

Board Exam Info
In the Bihar Board (BSEB) Class 12 Geography examination, this chapter typically carries around 5 to 8 marks. Questions usually include objective (multiple-choice) questions on specific mineral locations, short-answer questions differentiating between conventional and non-conventional energy sources, and long-answer questions focusing on the conservation and distribution of minerals in India.
Frequently Asked Questions
What is the difference between metallic and non-metallic minerals?
Metallic minerals contain metals and can be melted to extract new products (e.g., iron ore, copper), whereas non-metallic minerals do not contain extractable metals and are valued for their chemical or physical properties (e.g., limestone, mica).
Why is there a shift from conventional to non-conventional energy sources?
Conventional sources like coal and petroleum are exhaustible, cause heavy pollution, and contribute to global warming. Non-conventional sources are renewable, eco-friendly, and offer a sustainable alternative for future energy needs.
Which mineral is known as 'brown coal' and where is it found in India?
Lignite is known as brown coal. In India, important deposits are found in Neyveli (Tamil Nadu), as well as in parts of Gujarat, Jammu & Kashmir, and Rajasthan.
