Questions and Solutions
Question 1
- Which is not a factor of industrial location?
- Market (c) Population Density
- Capital (d) Power
- The earliest Iron and Steel Company to be established in India was:
- IISCO (c) Visvesvaraiya Iron and Steel Works
- TISCO (d) Mysore Iron and Steel Works
- The first modern cotton mill was established in Mumbai because:
- Mumbai is a port (c) Mumbai was the financial centre
- It is located near cotton growing area (d) All of the above
- The nucleus of the Hugli Industrial region is:
- Kolkata-Haora (c) Kolkata-Medinipur
- Kolkata-Rishra (d) Kolkata-Konnagar
- Which one of the following is the second largest producer of sugar:
- Maharashtra (c) Punjab
- Uttar Pradesh (d) Tamil Nadu
- The correct answer is (c) Population Density. While population density can indirectly affect labor supply and market size, it is not considered a primary direct factor for industrial location compared to market access, capital, and power availability.
- The correct answer is (b) TISCO. The Tata Iron and Steel Company (TISCO), established in 1907, was the earliest major iron and steel company in India.
- The correct answer is (d) All of the above. Mumbai's strategic advantages, including its port facilities for trade, its role as a financial center, and its proximity to cotton-growing regions, all contributed to the establishment of the first modern cotton mill there.
- The correct answer is (a) Kolkata-Haora. This conurbation forms the core or nucleus of the Hugli industrial region, a significant manufacturing belt in West Bengal.
- The correct answer is (b) Uttar Pradesh. While Maharashtra is a major producer, Uttar Pradesh is historically the second-largest producer of sugar in India, following Maharashtra.
Question 2
- Why do you think that the iron and steel industry is basic to the industrial development of any country?
- Name the two sectors of the cotton textile industries. How are they different?
- Why is the sugar industry a seasonal industry?
- What is the raw material base for the petrochemical industry? Name some of the products of this industry?
- The iron and steel industry is fundamental because it supplies essential materials for manufacturing countless products, from machinery and infrastructure to defense equipment and consumer goods. It acts as a mother industry, supporting the growth of numerous other sectors and driving national economic development.
- The two sectors are the Organized Sector and the Unorganized Sector. The organized sector utilizes modern machinery for spinning and garment production, whereas the unorganized sector employs traditional tools for handloom weaving, handicrafts, and sericulture.
- The sugar industry is seasonal because its primary raw material, sugarcane, is a seasonal crop. The availability of sugarcane fluctuates throughout the year, impacting the continuous operation of sugar mills.
- The raw material base for the petrochemical industry is crude petroleum and natural gas. Key products include plastics, synthetic fibers, resins, detergents, dyes, adhesives, and pesticides.
Question 3
- How did the Swadeshi movement give a major impetus to the cotton textiles industry?
- What do you understand by liberalisation, privatisation and globalisation. How have they helped industrial development in India?
- The Swadeshi movement, initiated in 1905, significantly boosted the Indian cotton textile industry by promoting the use of domestically produced goods. It encouraged a boycott of foreign textiles and fostered the growth of local mills, handlooms, and power looms. This movement aligned with the goal of 'swaraj' (self-rule) by strengthening indigenous production capabilities and reducing reliance on British imports, thereby fostering self-sufficiency and economic independence in the textile sector.
- Liberalisation, Privatisation, and Globalisation (LPG) refer to economic reforms introduced in India in the early 1990s. Liberalisation involved reducing government controls and regulations on industries, allowing greater autonomy in decision-making. Privatisation involved transferring ownership of state-owned enterprises to the private sector. Globalisation aimed at integrating the Indian economy with the world economy through increased foreign trade and investment. These reforms helped industrial development by fostering competition, improving efficiency, attracting foreign capital and technology, and expanding market access, ultimately leading to faster economic growth and modernization of industries.
Common mistakes
- Confusing factors of industrial location.
- Incomplete understanding of the 'basic industry' concept.
- Not clearly differentiating between organized and unorganized sectors.
- Overlooking the role of raw material seasonality in industry.
- Failing to connect historical movements (Swadeshi) to industrial growth.
Revision tips
- Focus on understanding the 'why' behind industrial locations and development.
- Create a table comparing the organized and unorganized cotton textile sectors.
- Map out major industrial regions and their key industries.
- Review the impact of economic policies like LPG on different industries.
- Practice explaining the foundational role of iron and steel with examples.
Practice MCQs
