Explanation:
1 ) The defining difference between ferrous and non-ferrous metals is in their iron content. Both types may be pure or alloys. In general, ferrous metals contain iron.
Common non-ferrous metals include aluminum, copper, tin, and precious metals like gold and silver.
2) Metallic Minerals are minerals in which metal elements are present in their raw form. Non-metallic minerals do not contain any metal substances in them. When metallic minerals are melted a new product is formed. Non-metallic minerals are often found embedded in young fold mountains and sedimentary rocks.
3 ) Conventional sources of energy are the natural energy resources which are present in a limited quantity and are being used for a long time. They are called non-renewable sources as once they are depleted, they cannot be generated at the speed which can sustain its consumption rate.
