{"slug":"cbse-class-10-social-science-manufacturing-industries","title":"Manufacturing Industries","description":"Why manufacturing matters, how industries are classified and located, and how industrial pollution can be controlled.","board":"CBSE","grade":"Class 10","subject":"Social Science","chapter":"Manufacturing Industries","url":"https://www.flipnlearn.app/deck/cbse-class-10-social-science-manufacturing-industries","studyUrl":"https://www.flipnlearn.app/deck/cbse-class-10-social-science-manufacturing-industries/study","cards":[{"id":"manufacturing","kind":"term-definition","front":"Manufacturing","back":"The large-scale production of goods by processing raw materials into more valuable products, such as paper from wood or aluminium from bauxite. It is a secondary-sector activity."},{"id":"why-manufacturing-is-the-backbone-of-development","kind":"concept-question","front":"Why is the manufacturing sector considered the backbone of economic development?","back":"It modernises agriculture and cuts dependence on farm income by creating jobs in the secondary and tertiary sectors. It helps remove unemployment and poverty, and reduces regional disparities when set up in backward areas. Exports bring in foreign exchange, and turning raw materials into higher-value goods brings prosperity."},{"id":"agriculture-and-industry-move-hand-in-hand","kind":"concept-question","front":"How do agriculture and industry move hand in hand?","back":"Agro-industries depend on agriculture for raw materials and in turn sell farmers irrigation pumps, fertilisers, pesticides, PVC pipes, machines and tools. This has raised farm productivity and made production more efficient."},{"id":"basic-industries-vs-consumer-industries","kind":"term-definition","front":"Basic (key) industries vs consumer industries","back":"Basic industries supply their products as raw materials for making other goods, such as iron and steel, copper smelting and aluminium smelting. Consumer industries make goods for direct use by consumers, such as sugar, toothpaste, paper, sewing machines and fans."},{"id":"industries-by-ownership","kind":"term-definition","front":"Public, private, joint and cooperative sector industries","back":"Public sector units are run by government agencies (BHEL, SAIL); private ones by individuals or groups (TISCO, Bajaj Auto). Joint sector units are run by the state and private parties together (Oil India Ltd). Cooperatives are owned by raw-material producers, workers or both, who share profits and losses, like Maharashtra's sugar mills."},{"id":"agro-based-vs-mineral-based-industries","kind":"term-definition","front":"Agro-based vs mineral-based industries","back":"Industries classified by the source of their raw material. Agro-based industries use farm produce, such as cotton, jute, silk and woollen textiles, sugar, tea, coffee and edible oil. Mineral-based industries use minerals and metals, such as iron and steel, cement, aluminium, machine tools and petrochemicals."},{"id":"why-textile-industry-is-unique","kind":"concept-question","front":"Why does the textile industry hold a unique position in the Indian economy?","back":"It contributes significantly to industrial production, employment and foreign exchange earnings. It is also the only industry in India that is self-reliant and complete across the whole value chain, from raw material to the highest value-added products."},{"id":"cotton-textile-localisation","kind":"concept-question","front":"Why was the early cotton textile industry concentrated in Maharashtra and Gujarat?","back":"These states lay in the cotton-growing belt, so they had raw cotton, a market, transport including port access, labour and a moist climate. The first successful mill opened in Mumbai in 1854."},{"id":"spinning-centralised-weaving-decentralised","kind":"concept-question","front":"Why is weaving kept decentralised while spinning is centralised in the cotton textile industry?","back":"Spinning is concentrated in Maharashtra, Gujarat and Tamil Nadu and is world class. Weaving is spread across handlooms, powerlooms and mills so that traditional skills and designs in cotton, silk, zari and embroidery can be kept alive. Handspun khadi also gives weavers large-scale home employment."},{"id":"jute-mills-in-hugli-basin","kind":"concept-question","front":"What factors explain the location of jute mills in the Hugli basin?","back":"Nearness to jute-growing areas; cheap water transport backed by rail, road and waterway links; abundant water to process raw jute; cheap labour from West Bengal, Bihar, Odisha and Uttar Pradesh; and Kolkata's banking, insurance and port facilities for exports."},{"id":"why-sugar-mills-are-shifting-south","kind":"concept-question","front":"Why are sugar mills shifting to southern and western states such as Maharashtra?","back":"Cane grown there has a higher sucrose content, the cooler climate allows a longer crushing season, and cooperatives work better in these states. Because the industry is seasonal, it suits the cooperative sector."},{"id":"why-iron-and-steel-is-a-basic-and-heavy-industry","kind":"concept-question","front":"Why is iron and steel called both a basic industry and a heavy industry?","back":"It is basic because every other industry depends on it for machinery. It is heavy because its raw materials (iron ore, coking coal and limestone in roughly a 4:2:1 ratio, plus manganese) and its finished goods are bulky, so transport costs are high."},{"id":"why-chhotanagpur-has-most-steel-plants","kind":"concept-question","front":"Why does the Chhotanagpur plateau have the greatest concentration of iron and steel plants?","back":"It offers low-cost iron ore, high-grade raw materials close together, cheap labour and a large potential home market."},{"id":"aluminium-smelting-location-factors","kind":"concept-question","front":"What makes aluminium valuable, and what decides where smelters are located?","back":"Aluminium is light, corrosion-resistant, a good heat conductor, malleable and strong when alloyed, so it replaces steel, copper, zinc and lead in many uses. Smelters need a regular supply of electricity and an assured, low-cost supply of bauxite."},{"id":"organic-vs-inorganic-chemicals","kind":"concept-question","front":"How do inorganic and organic chemical industries differ in products and location?","back":"Inorganic chemicals such as sulphuric acid, nitric acid, alkalies, soda ash and caustic soda are made in units spread widely across the country. Organic chemicals, mainly petrochemicals for synthetic fibres, rubber, plastics, dyes and drugs, are made near oil refineries or petrochemical plants."},{"id":"fertilizer-industry-and-potash","kind":"concept-question","front":"What does India's fertilizer industry produce, and why is potash imported?","back":"It makes nitrogenous fertilizers (mainly urea), phosphatic fertilizers, DAP and complex NPK fertilizers. Potash is entirely imported because India has no commercially usable reserves of potash or potassium compounds."},{"id":"it-and-electronics-industry","kind":"concept-question","front":"Why is the IT and electronics industry important to India, and where is it concentrated?","back":"It makes products from TVs and telephones to computers and telecom equipment, and its biggest impact has been on employment. Bengaluru is India's electronic capital, with major concentrations in Noida, Mumbai, Chennai, Hyderabad and Pune. Continued growth in hardware and software drives its success."},{"id":"how-industries-cause-air-pollution","kind":"concept-question","front":"How do industries cause air pollution?","back":"They release undesirable gases such as sulphur dioxide and carbon monoxide, and particles such as dust, mist and smoke from chemical and paper factories, brick kilns, refineries, smelters and fossil-fuel burning. Toxic gas leaks, as in the Bhopal tragedy, can be very hazardous."},{"id":"how-industries-cause-water-pollution","kind":"concept-question","front":"How do industries cause water pollution?","back":"Paper, pulp, chemical, textile and dyeing units, refineries, tanneries and electroplating industries discharge dyes, detergents, acids, salts, heavy metals such as lead and mercury, and synthetic chemicals into rivers."},{"id":"thermal-pollution-of-water","kind":"term-definition","front":"Thermal pollution of water","back":"Pollution caused when hot water from factories and thermal power plants is drained into rivers and ponds before it has been cooled, harming aquatic life."},{"id":"reducing-industrial-water-pollution","kind":"concept-question","front":"How can industrial pollution of freshwater be reduced?","back":"Reuse and recycle process water in successive stages, harvest rainwater, and treat hot water and effluents before release. Treatment has three phases: primary (mechanical screening, grinding, flocculation, sedimentation), secondary (biological) and tertiary (biological, chemical and physical, including recycling). Groundwater overdrawing should be regulated."},{"id":"reducing-industrial-air-and-noise-pollution","kind":"concept-question","front":"How can industries reduce air and noise pollution?","back":"Fit smoke stacks with electrostatic precipitators, fabric filters, scrubbers and inertial separators, and burn oil or gas instead of coal. Fit generators with silencers, redesign machinery for energy efficiency and less noise, use noise-absorbing material, and give workers earplugs."},{"id":"how-ntpc-protects-the-environment","kind":"concept-question","front":"How has NTPC reduced the environmental impact of its power plants?","back":"It optimises and upgrades equipment, minimises waste by maximising ash use, and provides green belts. It also manages ash ponds, recycles ash water, handles liquid waste, and runs ecological monitoring and online databases for its power stations."}]}
