6 Most Important Questions From Minerals And Energy Resources

The 6 selected questions are given here to revise.

Moreover, you will also learn how to write answers in Board exams that is short, precise and pointwise.

Question 1

How is energy an indispensable requirement of modern life? Explain with three examples.

Ans: Energy is an indispensable requirement of modern life because:

a) modern life is governed by technology and technology is driven by energy.

Three examples are:

i) Ever sector of National economy – agriculture, industry, transport, and commerce depends on energy resources.

ii) In the domestic sector also we need energy to run our electrical and electronic gadgets.

iii) Energy is the basic requirement of economic development.

Question 2

Why is there a pressing need to use non-conventional sources of energy in India? Mention an three reasons.

Ans: There is a pressing need to use non-conventional sources of energy in India because:

i) The consumption and requirement of energy is increasing day by day and conventional sources of energy are limited.

ii) Conventional sources of energy creates pollution of air, land and water.

iii) Rising prices and shortage of petroleum and natural gas have raised uncertainties about the security of energy supply.

Because of the above mentioned reasons, there is a pressing need to use non-conventional sources of energy in India.

Question 3

Explain the use of petroleum as energy resource and as a raw material?

Ans: Use of petroleum as energy resource:

i) Firstly, It is used as a fuel in the vehicles.

ii) Secondly, it is an important fuel to run railways and aircraft.

iii) Thirdly, It is also used to generate Thermal energy.

Use of petroleum as a raw material:

i) Firstly, It is used as lubricant for machinery.

ii) Secondly, Used as a raw material in the chemical industries.

iii) Thirdly, Also used in making fertilizers, synthetic rubber, synthetic fiber, plastics etc.

Question 4

How is mining activities injurious to the health of the miners and the environment?

Ans) To begin with, Mining activities are injurious to the health of the miners and the environment in the following manner:

i) Firstly, Pulmonary diseases: The dust and noxious fumes inhaled b the miners make them vulnerable to Pulmonary diseases.

ii) Secondly, Collapsing mine roofs: The risk of collapsing mines and fire in the coal mines are a constant threat to the miners and the environment.

iii) Finally, Contaminated water: Due to mining activities, the source of water in ponds, rivers and even the underground water gets contaminated, which ultimately adversely affect the life of miners.

Question 5

Solar energy has bright future in India. Do you agree with this statement? Comment.

Ans) Yes, I agree that solar energy has a bright future in India because:

i) Firstly,  India is a tropical country and receives abundant sunshine throughout the year.

ii) Secondly, It is an inexhaustible source of energy which is freely available in nature. As most of the Indians are poor, so they can easily afford and save money.

iii) Finally, Solar energy will minimize the use of firewood and will also contribute to the environmental degradation.

Question 6

What are the main types of formations in which minerals occur?

Ans) The main types of formations in which minerals occur are:

i) Firstly, Veins and Lodes: In Igneous and Metamorphic rocks, most of the metallic minerals are found in the form of veins and lodes.

ii) Secondly, Beds or layers: In sedimentary rocks, minerals occur in beds or layers.

Moreover, They are formed as a result of deposition, accumulation and concentration in the horizontal strata. For example coal and petroleum.

iii) Thirdly, Placer deposits: Certain minerals may occur as alluvial deposits on the banks of the rivers, in sands of valley floors and the base of hills. Important minerals found are gold, silver, platinum etc.

iv) Finally, Decomposition of surface rocks: Certain minerals are formed due to the decomposition of surface rocks and the removal of soluble contents, leaving a residual mass of weathered material containing ores. For example, Bauxite is formed this way.
