Class 10 Social Science - PUNJAB
Geography: Minerals and Energy Resources
The chapter Minerals and Energy Resources in Class 10 Social Science under the Punjab School Education Board (PSEB) explores the rich variety of mineral wealth and power resources found in India and Punjab. Students learn about the classification of minerals into metallic, non-metallic, and energy minerals, and their significance in industrial development. The chapter covers traditional energy sources like coal, petroleum, and natural gas, alongside modern renewable sources such as solar, wind, and biogas. Understanding this chapter is crucial for board exams as it tests geographical awareness, map skills regarding mineral locations, and the importance of resource conservation.

Minerals
Naturally occurring, homogenous substances with a definable internal structure that form the basis of industries and economic development.
Metallic Minerals
Minerals that contain metal and can be processed to extract valuable elements like iron ore, copper, and bauxite.
Non-Metallic Minerals
Minerals that do not contain metals, such as limestone, mica, and gypsum, widely used in cement and chemical industries.
Conventional Energy Sources
Traditional and non-renewable sources of energy like coal, petroleum, natural gas, and electricity that have been in common use for a long time.
Non-Conventional Energy Sources
Renewable and eco-friendly sources of energy such as solar energy, wind energy, tidal energy, and biogas.
Conservation of Resources
The sustainable and judicious use of minerals and energy resources to ensure they are available for future generations without harming the environment.

Frequently Asked Questions
What is the difference between metallic and non-metallic minerals?
Metallic minerals contain metals and yield metal when melted (e.g., iron ore, copper), while non-metallic minerals do not contain metals (e.g., limestone, mica).
Why are non-conventional sources of energy becoming more important today?
Non-conventional sources like solar and wind energy are renewable, eco-friendly, and inexhaustible, helping reduce pollution and dependency on exhaustible fossil fuels.
Which mineral is considered the backbone of industrial development?
Iron ore is considered the backbone of industrial development because it provides the base for machinery, tools, and steel production.
