Short Answer Type Questions [3 Marks]

Question 1.
Classify industries on the basis of capital investment. How are they different from one another? Explain with examples.
Answer:
On the basis of capital investment, the industries are classified into small scale industry and large scale industry.

· The maximum investment in small scale industry is upto ? 1 crore, e.g., toy industry.

· If the investment is more than one crore rupees, then it is known as large scale industry, e.g., iron and steel industry.

Question 2.
“The textile industry is the only industry in the country which is self-reliant and complete in the value chain”. Justify the statement.
Answer:
The textile industry is the only industry in the country which is self-relaint and complete in the value chain i.e. from raw materials to the highest value added products.
The statement can be justified as follows:

· Textile industry is dependent on agriculture and provides jobs to farmers, cotton boll pluckers and workers engaged in ginning, spinning, weaving, dying, packaging, tailoring and sewing. The industry by creating demand support industries like dyeing.

· It contributes significantly to industrial production. India h^s world-class production in spinning and capable of using all the fibers that are produced.

· Textile industry has been a major foreign exchange earner with increase in foreign trade across the world.

· It contributes significantly to the National GDP.

Question 3.
Classify industries on the basis of source of raw material. How are they different
from each other?
Answer:
On the basis of the sources of raw materials used industries are classified into agro-based industries eg cotton, silk, rubber, tea etc. and mineral based industries, e.g., iron and steel, cement etc.
They are different from each other in the following ways:

· Agro based industries are based on agricultural raw materials, e.g. cotton, wool, sugarcane etc. Mineral based industries use minerals and metals as raw materials e.g. iron ore, bauxite etc.

· Agro based industries depend on manufacturing industries for machinery, tools and implements. On the other hand, mineral based industries feed manufacturing industries

Question 4.
Suggest any three steps to minimise the environmental degradation caused by the industrial development in India.
Answer:
Environmental degradation can be minimised by

· Proper fuel selection and utilisation, e.g., CNG should be used in automobiles instead of diesel or petrol.

· Equipments to control aerosol emissions like inertial seprators, filters, precipitators and scrubbers should be used.

· Smoke can be prevented by the use of oil instead of coal in industries.

Question 5.
India is an important iron and steel producing country in the world. Yet we
are not able to perform to our full potential”. Suggest and explain any three measures to get full potential.
Answer:
The following measures can enable us to perform to our full potential:

· Resources need to be allocated for research and development to add up steel production.

· Apart from this regular supply of coking coal and electricity has to be dealt with.

· Productivity of labour needs to be increased through proper training.

· Efficient system of roadways and railways has to be maintained for quick delivery of raw material and finished goods.

· Moreover domestic demand of iron and steel has to be increased

Question 6.
Classify industries on the basis of their main role. How are they different from each other?
Answer:
According to their main role the industries are classfied as:

· Basic or key industries. These industries supply their raw materials to manu¬facture other goods, e.g., iron and steel, copper smelting etc.

· Consumer industries. These industries produce goods for direct consumption by consumers, e.g., sugar, fans paper, toothpaste, etc.

Question 38.
Explain any five measures to control industrial pollution in India.
Answer:
Industries are responsible for four kinds of pollution-air, water, land and noise
pollution. Industrial pollution can be controlled by:

· Industries should be set up in distant areas away from human settlements.

· Minimise the use of water processing through reusing and recycling.

· Treating hot water and effluents before releasing them in rivers and ponds.

· Particulate matter in the air can be reduced by fitting smoke stacks to factories with electrostatic precipitators. Smoke can be reduced in factories by using gas or oil instead of coal.

· Machinery can be redesigned to increase energy efficiency and reduce noise.

Question 39.
How do industries pollute environment? Explain with five examples.
Answer:
Industries pollute the environment in many ways. They cause pollution in four
ways-air, water, land and noise.

· Water pollution is caused by the discharge of industrial effluents into the water bodies with treating it.

· Dumping of wastes, harmful chemicals and industrial effluents e.g. packaging, and garbage makes soil useless. It also results in contamination of groundwater through seepage of rainwater.

· Air pollution is caused by release of undesirable gases and smoke like sulphur dioxide, carbon monoxide, air-borne particulate materials like dust, sprays, mist and smoke. Smoke is emitted from paper mills, burning of fossil fuels, smelting plants etc.

· Factory equipments, generators, saws cause noise pollution.

· Thermal pollution of water occurs when hot water from factories and thermal plants is drained into rivers and ponds before cooling.

Question 40.
How do industries pollute water? Suggest any four measures to control water pollution.
Answer:

· Water pollution is caused by the discharge of industrial effluents into the water bodies.

· Thermal pollution occurs when hot water from factories and thermal power plant is drained into rivers and ponds, before cooling. Aquatic life is effected by it.

· Rainwater percolates into the soil carrying pollutants to the ground and leading to contamination of ground water.

· The major industries causingwater pollution are paper pulp, textitle, chemical, tanneries, petroleum, refineries and electroplating industries give out dyes, detergent, acids, salts, heavy metals like lead, synthetic chemicals, plastics and rubber. Fly ash phospo-gypsum and iron and steel slags are the solid wastes discharged into the water.
Measures to control water pollution are:

· Minimising the use of water by reusing or recycling it in two or more stages.

· Harvesting of rainwater to meet water needs.

· Treatment of industrial effluents and hot water before releasing them in rivers and ponds.

· Overdrawing of ground water reserves by industries should be minimised.

Short Answer Type Questions [3 Marks]

Question 42.
How do industries pollute air? Explain the effects of pollution.
Answer:
Industries cause different types of pollution—land, air and water.

· Air pollution is caused by the release of undesirable gases and smoke like sulphur dioxide, carbon monoxide.

· Air-borne particulate materials like dust, sprays, mist and smoke cause air pollution.

· Smoke is emitted from chemical and paper mills, brick kilns, refineries, smelting plants.

· Burning of fossil fuels in big and small factories which do not follow pollution norms. Toxic gas leaks can be very hazardous with long-term effects.

· Air pollution adversely affects human health, plants and animals. In human beings, air pollution can cause respiratory problems. Smog in the atmosphere cause respiratory problems.

Question 43.
Why was cotton textile industry concentrated in the cotton growing belt of Maharashtra and Gujarat in the early years? Explain any three reasons.
Answer:
The cotton textile industry was mainly concentrated in the cotton growing areas because of the following reasons:

· Abundant availability of raw cotton due to favourable climate and presence
of black soil.

· Huge market for cotton textile in and around Mumbai.

· Well-developed means of transport including the port facilities in Mumbai.

· Cheap labour from the adjoining areas.

· Mild and moist climate is favourable for spinning the cotton yarn.

Question 44.
