Metallic Minerals
Minerals that provide metallic elements and can be melted to extract new products, such as iron ore, bauxite, and manganese, mainly found in plateau regions.
Non-Metallic Minerals
Minerals that do not yield new metals when melted, including limestone, mica, and dolomite, widely used in cement and chemical industries.
Conventional Energy Sources
Traditional, non-renewable sources of energy like coal, petroleum, natural gas, and thermal electricity that take millions of years to form.
Non-Conventional Energy Sources
Renewable and eco-friendly sources of energy such as solar, wind, tidal, and geothermal energy that help reduce carbon footprints.
Sustainable Resource Management
The practice of using resources judiciously and efficiently to meet current needs without compromising the ability of future generations to meet theirs.

Frequently Asked Questions
What is the difference between metallic and non-metallic minerals?
Metallic minerals contain metals and can be melted to extract them (e.g., iron ore, copper), while non-metallic minerals do not contain metals and lack malleability (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, clean, and sustainable.
Are map-based questions from this chapter important for board exams?
Yes, locating important mineral fields (like iron ore mines in Chota Nagpur) or thermal/nuclear power plants on an outline map of India or the world is a frequent and scoring question in the HSC exam.
