Frequently Asked Questions
What is the difference between metallic and non-metallic minerals?
Metallic minerals contain metals (e.g., iron ore, bauxite) and can be melted to extract new products, whereas non-metallic minerals do not contain metals (e.g., mica, limestone) and lack metallic luster.
Why are non-conventional sources of energy gaining importance in India?
Non-conventional sources like solar and wind energy are renewable, eco-friendly, and help reduce our heavy dependence on depleting fossil fuels like coal and petroleum.
Which state in India is a major producer of mica?
Jharkhand and Bihar are historically known for rich deposits of mica, along with Andhra Pradesh.
