MANUFACTURING INDUSTRIES
NCERT TEXTBOOK QUESTIONS
Q 1 Why is iron and steel industry termed as basic industry?
Ans. Basic or key industries supply their products as raw materials to other industries to
Manufacture their goods.
 Iron and steel industry is termed as a basic industry because
(a) It produces iron and steel which in turn is used for manufacturing machines, tools and
Equipment’s. Machineries and tools are basic for any manufacturing process. Thus, iron
And steel industry plays a key role in the development of any manufacturing industry
And agriculture.
(b) Iron and steel industry provides raw materials for heavy engineering, automobiles, ship
Building, manufacturing of railway engines, locomotives, etc. The development of
These industries is dependent on the supply of iron and steel.
Many of the items used by us in our daily life, from a tiny nail to big railway
Locomotives, are made of iron.

Q 2 Describe four physical and four human factors that affect the location of an industry.
Ans. Industrial locations are complex in nature. They are influenced by a number of factors that
Determine their location in region.
The PHYSICAL FACTORS that influence that location of industries are as follows:
(a) Availability of raw materialsRaw materials for industries range from agricultural
     Products to minerals. Raw material required for the industry must be available cheaply
     And at close range or at well-linked places. In case of industries using bulky raw
     Materials like iron, bauxite, etc., the ideal location is near the sources of raw materials.
(b) Availability of  Power  Power, energy or fuel is essential for the working of any industry,
     For running machineries and as fuel for the furnaces and smelters. So, power resources
     Like coal and electricity must be available in abundance in the vicinity of the site
     Chosen for the industry.
(c) Availability of WaterWater is needed in abundance by almost all industries, e.g. cotton 
     and   jute
     Textiles for processing, cleaning and cooling of machineries. So many industries are
     Located near rivers and other water bodies.
(d) Favourable climateClimate affects production process, for example, humid
     Climate is suitable for spinning of cotton yarns. The industry must be located in an area
     Where the climate does not damage the raw materials or finished products.

HUMAN FACTORS influencing the location of industries are:
(a) Availability of Cheap Labour — Cheap and efficient labour must be available in the region surrounding the
      Industry for proper functioning of the industry.
(b) Availability of Capital — Industries require finances in large amounts. For setting up an industry in
     a chosen site, large amount of cash guarantees and banking facilities are required.
(c) Availability of Market — The goods produced must have a market for their sale. The market
      Influences the demand as well as type of goods produced in a region.
(d) Transport facilities — Well-linked road, railways or waterways must be available for
      Transfer of raw materials and manufactured products to and from the industrial area.

Q 3 How do industries Pollute the Environment?
Ans. Pollution is a negative effect of industrialization. It results in degradation of the
Environment and affects human health, animals, plants and the atmosphere as a whole.
It contributes to major environmental problems like land degradation, water scarcity, health
Hazards and, on a larger scale, global warming and climate change.
Industries are responsible for four types of pollution, namely, air, water, land and noise.
Air pollution is caused by presence of high proportion of undesirable gases, such as
Sulphur dioxide and carbon monoxide, dust, sprays, mist and smoke in the atmosphere due
To emission from industrial units. Smoke emitted by chemical and paper factories, brick
Kilns, refineries and smelting plants and burning of fossil fuels in big and small factories
That ignore pollution norms cause enormous pollution.
Toxic gas leaks from factories are extremely hazardous.
Water pollution is caused by organic and inorganic industrial wastes and affluent
Discharged into rivers and other water bodies.
The main culprits in this regard are paper, chemical textiles and dyeing, petroleum
Refineries, tanneries and electroplating industries. They let out dyes, detergents, acids, salts
And heavy metals like lead and mercury, pesticides, fertilizers, synthetic chemicals with
Carbon, plastics and rubber, etc., into water bodies. They turn big and small rivers into
Toxic streams.
Dumping of wastes specially glass, harmful chemicals, industrial effluents, packaging,
Salts and garbage renders the soil useless due to land pollution. Rainwater percolates to
Into the soil carrying these pollutants and contaminates ground water.
Noise pollution is by industrial and construction activities, machineries and factory
Equipment’s, generators, saws and pneumatic and electric drills.

Q 4 Agriculture and industry are complimentary to each other.’ Justify the statement.
Ans. A close relationship exists between agriculture and manufacturing industries. Each of them
Complement each other.
Each of them serves as market for goods produced by the other and in the process raises
Demand for each other's goods.
For example, the agro-based industries, like textiles, sugar, etc., depend upon agriculture for
Raw materials. These industries have given a major boost to agriculture by raising their demand
And hence, productivity. Manufacturing industries sell the products such as irrigation pumps,
Fertilisers, insecticides, pesticides, plastic and PVC pipes, agricultural machineries and tools,
etc., to the farmers. Agriculture serves as their market and effects their development.
These inputs from industries assists agriculturists in increasing productivity as well as have
Made the production processes very efficient.

Q.5. Why did the traditional cotton textile industry of India receive a setback during the
Colonial period?
Ans. The traditional cotton textile industry of India suffered a setback during the colonial period
Because of competition from mill-made cloth from England. In England cotton textiles were
Produced in large quantities with the help of power loom. The surplus was sold in India for
Profit as India was then a colony of England. Mill-made cloth was cheaper on account of large
Scale production. On the other hand, our traditional textiles used ancient techniques like hand spinning
And handloom weaving. Hence, its production could not compete with mill-made
Cloth of England.

Q.6. Mention any six factors responsible for the location of Jute mills in the Hugli basin.
(i) Proximity of the jute producing areas.
(ii) Cheap water transport facilities.
(iii) Good network of railways, roadways and waterways to facilitate movement of raw
       Materials to the mills.
(iv) Abundant water for processing raw jute.
(v) Cheap labour from West Bengal, Bihar, Orissa and Uttar Pradesh.
(vi) Bank, insurance Facilities Provided by Kolkata
(vii) Port facilities for export of Jute goods.

Q.7. Distinguish between an integrated steel plant and a mini steel plants stating three points
of distinction.
(i) An Integrated steel plant is larger than Mini Steel Plant.
(ii) Mini steel plant use steel scrap and sponge iron while integrated steel plant use basic raw
      Materials i.e. iron ore for making steel.
(iii) Mini steel plant produces mild and alloy steel while integrated steel plant produces only steel.

Q.8. Explain any three problems faced by cotton textile industries in India.
Three problems faced by cotton textile industries in India are as follows:
(i) Power supply is erratic and machineries are back dated.
(ii) Output of labour is low.
(iii) Facing stiff competition with the synthetic fibre industry.

Q.9. Why is cotton textile industry the largest industry in India today? Give any three reasons.
 (i) Cotton textile industry contributes 14 percent of the total industrial production.
(ii) It provides employment to 35 million persons directly – the second largest after
     Agriculture.
(iii) It earns foreign exchange of about 24.6 percent (4 percent of GDP).

Q.10. Why are most of the Iron and steel plants of India concentrated in Chhota Nagpur
Plateau region? Give three reasons.
Ans. Chhota Nagpur plateau region has the maximum concentration of steel plants because of the
        Following factors:
(i)   Low cost of iron ore and high grade raw materials in proximity.
(ii)  Cheap labour.
(iii) Vast growth potential in the home market.

Q.11. “The economic strength of a country is measured by the development of manufacturing
Industries”. Elaborate the statement.
Ans. Resource utilization cannot be made without manufacturing industry. Manufacturing industry
Transforms raw materials into finished products which added value to it. Countries having a
Good number of manufacturing industry can able to utilize resources more fruitfully and are
Therefore they considered as advanced country. India's contribution to manufacturing industry
Is 17 per cent as compared to 30 percent for Japan and 25 percent for France respectively.

Q.12. Discuss the role of NTPC in paving the way to control environmental degradation.
