Question

Distinguish between the following in not more than 30 words. a) Ferrous and non-ferrous minerals b) Conventional and non-conventional sources of energy.

Answer 1

a)Ferrous and Non-ferrous minerals

Ferrous minerals:

• Out of the total value of the production of metallic minerals, around three-fourths are accounted for by Ferrous minerals.
• For the development of metallurgical industries, a strong base is provided by Ferrous minerals.
• After meeting the internal demands of India, substantial quantities of ferrous minerals are exported by India. Iron ore and Manganese are examples of ferrous minerals.

Non-Ferrous Minerals:

• The production and reserves of non-ferrous minerals in India are not up to expectations.
• Some examples of non-ferrous minerals are gold, zinc, lead, bauxite, and copper.
• These non-ferrous minerals play a vital role in the electrical, engineering, and metallurgical industries.

b) Conventional and non-conventional sources of energy

Energy sources can be classified into two types: non-conventional sources of energy and conventional sources of energy.

Conventional Sources of energy

• From different fuels like natural gas, petroleum, and coal; energy can be generated.
• Conventional sources of energy include natural gas, petroleum, coal, cattle dung cake, and firewood.

Non-Conventional Sources of Energy

• Non-conventional sources of energy include atomic energy, biogas, the geothermal, tidal, wind, and solar.
• Serious environmental problems are caused by the use of fossil fuels.
• Hence it is very important to use non-conventional sources of energy.
• India has abundant biomass, wind, water, and sunlight sources.
• To develop renewable energy resources, India has lots of programs.
