Answer the following questions in 30 words.
- What is manufacturing?
Answer: Processing of raw materials to produce finished or intermediate goods is known as manufacturing. Generally, the form of raw materials gets changed in manufacturing.
- Name any three physical factors for the location of the industry.
Answer: Physical factors essential in deciding the location of an industry are − availability of rawmaterials, availability of transportation and the proximity to the market.
- Name any three human factors for the location of an industry.
Answer: Human factors essential in deciding the location of an industry are − availability of cheaplabour, availability of human resources such as consultants and financial advisor, and capital.
- What are basic industries? Give an example.
Answer: Basic or key industries are those which supply their products or raw material to other industries to manufacture goods e.g. iron and steel industries which supply raw material to automobile industries.
- Name the important raw materials used in the manufacturing of cement?
Answer: Cement industry requires bulky and heavy raw materials like lime stone, silica, alumina and gypsum. Coal and electric power are also needed.
Answer the following questions in about 120 words.
- How are integrated steel plants different from mini steel plants? What problems does theindustry face? What recent developments have led to a rise in the production capacity?
Answer: Integrated steel plants are different from mini steel plants in many aspects. An integrated steelplant is large and handles everything in one complex—from integrating raw materials to steelmaking, rolling and shaping. On the other hand, a mini steel plant is smaller, has electricfurnaces, uses steel scrap and sponge iron, and has re-rollers that use steel ingots as well. Itproduces mild and alloy steel of given specifications.
The problems faced by this industry are: (a) high costs and limited availability ofcoking coal; (b) lower productivity of labour; (c) irregular supply of energy; and (d) poorinfrastructure; (e) import of good quality steel.
Recent developments viz. liberalisation and foreign direct investments have given a boost to the industry with efforts of private entrepreneurs.
- How do industries pollute the environment?
Answer: Although industries contribute significantly to India’s economic growth and development, the increase in pollution they have caused cannot be overlooked. They are responsible for four type of pollutions: air, water, land and noise.
- Air pollution is caused by smoke released by chemical and paper factories, brick kilns, refineries andsmelting plants, and burning of fossil fuels in factories ignoring pollution norms. Also release of toxic gases directly in air causes air pollution.
- Water pollution is caused by organic and inorganic industrial wastes and effluents discharged into rivers. The main culprits of this pollution are paper, pulp, chemical, textile, dyeing, petroleumrefineries, tanneries and electroplating industries. The major solid wastes released into riversin India are fly ash, phospo-gypsum, and iron and steel slags. Also thermal pollution of water isanother form of water pollution, caused by the emission of hot water from factories and thermalpower plants into rivers and ponds.
- Soil and water pollution are closely related. Polluted water reserves like pond pollute nearby land. Besides, dumping of wastes specially glass, chemical, industrial effluents, plastics etc. renders soil useless.
- Noise pollution results from industrial and construction activities, machinery,generators, and saws, pneumatic and electric drills.
- Discuss the steps to be taken to minimise environmental degradation by industry?
Answer: With the rapid growth of industries, the problem of environment pollution is also increasing. This led to world community to adopt sustainable development model and take immediate steps to minimise environmental degradation by industries.
- To control water pollution, industrial effluents and hot water need to be treated on all three levels(primary, secondary and tertiary); the use of water for processing should be minimised viareuse and recycling; rainwater harvesting should be practised in water scarce regions, and ground waterusage should be regulated by law to check the overdrawing of ground water.
- Organic farming should be promoted and use of pesticides and chemical fertilisers should be minimised in order to check the soil and ground water pollution.
- Factories should be filleted with electrostatic precipitators, smoke filters, fabric filters, scrubbers and initial separators to minimise air pollution.
- Oil and gas should be used in industries to reduce smoke.
- Machinery and equipment should be fitted with silencers and should be redesigned to increase efficiency and reduce noise. Noise absorbing materials may also be used.
