Class 10 Geography Chapter 5 Question 2 :
Answer the following questions in about 30 words.
(i) 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 :
(a) Difference between Ferrous Minerals and Non Ferrous Minerals

Ferrous MineralsNon Ferrous Minerals
Ferrous Minerals Contain iron Non Ferrous minerals do not contain Iron.
India is rich in Ferrous mineralsIndia is poor in non ferrous minerals
Iron Ore and Manganese are important ferrous mineralsCopper, Bauxite , tin , lead are important non ferrous minerals

(b) Difference between Conventional and Non-Conventional Sources of Energy

Conventional Sources of EnergyNon Conventional Sources of Energy
Conventional sources of energy are used at large scale and for a long timeNon-conventional sources of energy are used at small scale and are new.
Conventional sources of energy are non-renewable source of energy. Coal, Petroleum firewood, cattle dung cake, natural gas and electricity are its example.These are renewable sources of energy. Foe example : Wind energy, Tidal Energy, Geothermal Energy, Atomic Energy, Solar Energy ,etc
These are going to last long for hundred to two hundred years.These are going to last long forever.
These cause air and water pollutionThese don’t cause and water pollution.

(ii) What is a mineral?
Answer :
Minerals is a homogenous , naturally occurring substance with a definable internal structure. For example diamond, talc ,etc

(iii) How are minerals formed in igneous and metamorphic rocks?
Answer :
In igneous and metamorphic rocks minerals may occur in the cracks, crevices, faults or joints.
The smaller occurrences are called veins and the larger are called lodes.
In most cases, they are formed when minerals in liquid/ molten and gaseous forms are forced upward through cavities towards the earth’s surface.
They cool and solidify as they rise. Major metallic minerals like tin, copper, zinc and lead etc. are obtained from veins and lodes

(iv) Why do we need to conserve mineral resources ?
Answer :
We need to conserve mineral resource because of the following reasons :
1. Minerals are integral part of our life economy .
2. Everything we use , from a tiny pin to a building or a bus or a big ship, all are made from minerals.
3. The country earns foreign exchange from the export of minerals .
4. The geological processes of mineral formation are so slow that the rates of replenishment are infinitely small in comparison to the present rates of consumption.

5. Mineral resources are, therefore, finite and non-renewable.
6. Rich mineral deposits are our country’s extremely valuable but short-lived possessions.
7. Continued extraction of ores leads to increasing costs as mineral extraction comes from greater depths along with decrease in quality
