Question - 5 : - What is manufacturing?
Answer - 5 : - Manufacturing is the production of goods in large quantities after processing from raw materials to more valuable products. For e.g.,- paper is manufactured from wood, sugar from sugarcane, iron and steel from iron ore and aluminium from bauxite.
Question - 6 : - Name any three physical factors for the location of the industry.
Answer - 6 : -
Three physical factors for the location of the industry are:
1. Availability of raw materials
2. Closeness to market
3. Availability of power
For e.g., тАУ Jute textile industry is concentrated in West Bengal as the jute producing areas lie in the Hugli basin and there is cheap water transport for transportation and for processing of jute.
Question - 7 : - Name any three human factors for the location of an industry
Answer - 7 : -
Three human factors for the location of an industry are:
1. Labour
2. Capital

Question - 10 : - How are integrated steel plants different from mini steel plants? What problems does the industry face?
Answer - 10 : - What recent developments have led to a rise in the production capacity?
Answer
Integrated steel plants are large and handle everything in one complex тАУ from putting together raw material to steel making, rolling and shaping.
Mini steel plants are smaller, have electric furnaces, use steel scrap and sponge iron. They have re-rollers that use steel ingots as well. They produce mild and alloy steel of given specifications.
The challenges faced by the steel industry are:
1. High cost and limited availability of coking coal
2. Lower productivity of labour
3. Irregular supply of energy
4. Poor infrastructure
Recent developments such as liberalisation and foreign direct investment (FDI) have given a boost to the industry with the efforts of private entrepreneurs.
