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

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 is not upto the expectations.
  • Some of the 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, coal; energy can be generated.
  • Conventional sources of energy include: natural gas, petroleum, coal, cattle dung cake, firewood.

Non Conventional Sources of Energy

  • Non-conventional sources of energy include atomic energy, biogas, geothermal, tidal, wind, solar. 
  • Serious environmental problems are caused by 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 programmes.
