Distinguish between the following
(a) Ferrous and non-ferrous minerals
(b) Conventional and non-conventional sources of energy.
(a)Ferrous Minerals:
Ferrous minerals account for about three fourths of the total value of the production of metallic minerals. They provide a strong base for the development of metallurgical industries. India exports substantial quantities of ferrous minerals after meeting her internal demands.
(b)Non-ferrous Minerals:
India's reserves and production of non- ferrous minerals is not very satisfactory. However, these minerals, which include copper, bauxite, lead, zinc and gold, play a vital role in a number of metallurgical, engineering and electrical industries. Let us study the distribution of copper and bauxite.
Conventional Sources of Energy:
1. Conventional source of energy have been used since the early times.
2. Coal, Petroleum, natural gas, hydro-electricity, thermal power are the source of energy.
3. All conventional sources of energy except hydro-electricity are exhaustible.
4. These source cause environmental pollution.
5. These source require huge capital.
Non-Conventional Sources of Energy:
1. Non- conventional source of energy have came into the use only recently.
2. Wind energy, solar energy, tidal energy, geothermal, biogas are example of these source of energy.
3. Most of the non- conventional sources of energy are inexhaustible.
4. These sources do not cause environmental pollution.
5. Small amount of money is sufficient to have these sources.
