Class 10 Social Science - KERALA
Geography: Minerals and Energy Resources
The Class 10 Kerala SCERT Social Science chapter 'Geography: Minerals and Energy Resources' explores the vital natural resources that drive modern industrial development and daily life. Students learn about the classification of minerals into metallic and non-metallic, their distribution across India, and the importance of conservation. The chapter also covers conventional energy sources like coal, petroleum, and electricity, alongside renewable, eco-friendly non-conventional sources like solar, wind, and biogas. Understanding this chapter is crucial for board exams as it links resource distribution with economic growth and sustainable development, frequently featuring map-marking questions and short answers.

Minerals
Naturally occurring, homogeneous substances with a definite internal structure, found in ores within rocks.
Metallic Minerals
Minerals that contain metal and are sources of metal, such as iron ore, bauxite, and manganese.
Non-Metallic Minerals
Minerals that do not contain metals, such as mica, limestone, and gypsum.
Conventional Energy Resources
Traditional sources of energy that are exhaustible with prolonged use, including coal, petroleum, natural gas, and thermal electricity.
Non-Conventional Energy Resources

Frequently Asked Questions
What is the difference between metallic and non-metallic minerals?
Metallic minerals contain metals and yield them when processed (e.g., iron ore, copper), while non-metallic minerals do not contain metals (e.g., limestone, mica).
Why are non-conventional energy sources becoming more popular?
They are eco-friendly, renewable, inexhaustible, and help reduce our dependence on exhaustible fossil fuels like coal and petroleum.
Why is the conservation of minerals necessary?
Minerals are non-renewable resources that take millions of years to form. Rapid consumption depletes reserves, making conservation essential for sustainable economic development.
