GSEB Class 10 Social Science Solutions Chapter 13 Manufacturing Industries

I. Answer the Following Questions in Details.

Question 1. Where are sugar factories located? Why?
Answer: Sugar comes from sugarcane. We need to get the juice from sugarcane within 24 hours of cutting it. If this does not happen, the sugarcane's water content goes down. When sugarcane loses water, or dehydrates, it gives less sugar. Because of this, sugar factories are found close to where sugarcane is grown.
In simple words: Sugar factories are located near sugarcane farms because sugarcane must be processed quickly after harvest to get the most sugar, as its water content decreases over time.

Exam Tip: Remember to link the location of sugar factories directly to the perishable nature of sugarcane and the need for immediate processing to maximize sugar yield.

Question 2. Write a note on the iron and steel industry of India.
Answer: Iron is the foundation of modern industries and economic progress. It is also a basic industry that helps in the development of machines, buildings, and other similar industries. The method of making iron has a long history in India. Long ago, people from Damasca would purchase iron from India to make swords. Currently, India is fifth globally in producing iron and steel. The first factory in India to make iron was set up in Portonovo, Tamil Nadu. But, it was shut down for various reasons. In 1874, India got its first blast furnace in Kulti, West Bengal, for processing iron ore. In 1907, Jamshedji Tata launched the Tata Iron and Steel Company (TISCO) at Jamshedpur to produce iron and steel on a large scale. Later, other big iron and steel factories were set up in places like Durgapur (West Bengal), Bhadravati (Karnataka), Bhilai, Rourkela, Bokaro, Vishakhapatnam, and Salem. A smaller steel plant exists near Hajira in Gujarat. Iron ore, coal, limestone, and manganese serve as the basic materials for making iron and steel. All iron and steel factories, apart from Tata's, are managed by the 'Steel Authority of India Limited' (SAIL).
In simple words: India's iron and steel industry is crucial for modern development and has a long history. It ranks fifth globally in production, with key plants established by Tata and others, using raw materials like iron ore and coal. SAIL manages most factories except Tata's.

Exam Tip: When writing about industries, include historical context, current global standing, key raw materials, important production centers, and significant managing bodies.

Question 3. Write short note on the importance of industries.
Answer: Industry is the process where humans transform natural resources into useful forms, based on their knowledge, culture, and financial ability. Importance of Industries: Nowadays, countries greatly rely on industries to thrive. A country cannot reach economic growth without growing its industries. Nations that have prioritized industrial growth have seen strong economic progress. Countries such as the US, Russia, Japan, and South Korea are wealthy and advanced because of their strong industrial growth. Conversely, nations with underdeveloped or less developed industries struggle to fully and properly use their natural resources. So, they must sell their natural resources cheaply and buy finished goods made from the same raw materials from other countries at a higher cost. Manufacturing industries contribute approximately 29% to the country's total output.
In simple words: Industries are vital for a nation's wealth and progress, turning natural resources into useful items. Countries with strong industries achieve economic growth, while those without struggle to use their resources effectively and often end up buying finished goods at higher prices.

Exam Tip: Focus on how industries drive economic development, create value from raw materials, and contribute to national income, citing examples of developed nations.

Question 4. Write a short note on cotton textile industry of Indian
Answer: The cotton textile industry is extremely important for India's economy. Of all industries, this one hires the most people in India, roughly 3.5 crore individuals. India is second only to China in exporting cotton textiles. Therefore, the cotton textile sector is crucial for both job creation and output. Initially, cotton textile factories were primarily set up in Mumbai and Ahmedabad. Mumbai saw the launch of India's first cotton mill. After that, Shahpur Mills and Calico Mills were built in Ahmedabad, Gujarat. Affordable cotton, available workforce, transportation, export ports, and good markets were key factors in setting up these industries. Now, cotton textile factories are spread throughout the nation. They are now found in roughly 100 Indian cities. But, the main hubs include Mumbai, Ahmedabad, Bhiwandi, Sholapur, Kolhapur, Nagpur, Indore, and Ujjain. Mumbai has many cotton mills and is therefore known as India's 'Cottonopolis'. Cotton textile production also happens in other Maharashtra cities like Pune, Kolhapur, Aurangabad, and Jalgaon. Ahmedabad has a huge number of cotton textile industries. Hence, it is known as the 'Manchester of the East' and also 'Denim City of India'. Cities such as Vadodara, Kalol, Bharuch, Surat, Porbandar, Bhavnagar, and Rajkot also have many textile units. Coimbatore is Tamil Nadu's main center, while Chennai and Madurai are other key textile hubs in the state. Kanpur, Itawah, Agra, and Lucknow are major cotton textile centers in Uttar Pradesh. Indore, Gwalior, Ujjain, and Devas are key centers in Madhya Pradesh. Kolkata, Howrah, and Murshidabad are big cotton textile centers in West Bengal. The cotton textile industry is also found in Rajasthan, Punjab, and Haryana. It is clear that the cotton industry is not limited to certain states but is spread throughout India. This is because of the large Indian market and strong infrastructure like transport and banks. Currently, India's cotton textile sector has grown significantly, sending cloth to Russia, the UK, the US, Sudan, Nepal, Australia, France, and South Africa. The drawback of this industry is facing strong rivalry because of issues like not enough high-quality cotton, outdated machines, inconsistent electricity, competition from synthetic fabrics, and global brands.
In simple words: The cotton textile industry is vital for India, employing many people and ranking second in exports. Key centers include Mumbai (Cottonopolis), Ahmedabad (Manchester of the East), and others across states, thanks to cheap cotton and good infrastructure. However, it faces challenges from old machinery, power issues, and competition from artificial fibers and global brands.

Exam Tip: Outline the importance of the industry, mention key historical and current centers, list factors aiding its growth, and identify the main challenges it faces today.

II. Write to the Point Answer of the Following Questions.

Question 1. Mention the steps to curb environmental degradation.
Answer: Ways to reduce environmental damage: Industries form the core of a nation's economy. They ought to be grown to fix many issues facing the country. The nation should advance its industries so that economic growth and development do not greatly harm the environment. Pollution levels and impact can be lessened through good planning, techniques, and tools. Pollution can also be decreased by using appropriate raw materials and fuel. Air pollution in factories can be managed with filters, scrubbers, and precipitators. Water pollution can be stopped by releasing industrial waste only after it has been correctly treated. Furthermore, industrial water can be cleaned and reused after processing.

III. Short Answer Type Questions

Question 1. Industrial development started very late in India. Give reason.
Answer: During the Industrial Revolution, India was under British Rule. The British implemented unfair policies that prevented Indians from starting or growing industries. For instance, the first charcoal-based iron melting industry began in 1853 but failed due to British policies. The British would buy raw materials cheaply from India, produce goods in England, and then sell those goods back in India. As a result, local industries could not flourish, and several restrictions were placed on Indians producing goods and setting up businesses. Because of these reasons, India's industrial foundation broke down during British Rule, preventing it from achieving industrial development as early as other developed nations.
In simple words: India's industrial growth was slow because the British ruled with unfair policies. They bought cheap raw materials, made goods in England, and sold them back, stopping Indian businesses from growing.

Exam Tip: When explaining historical reasons, focus on key events like the Industrial Revolution and the impact of colonial policies (e.g., British Rule) to build a strong argument.

Question 2. Enlist first few Industries of India and their set-ups.
Answer: The first charcoal-based iron melting industry was established as early as 1853, but it did not succeed due to British policies. The first cotton textile industry began in 1854. A jute mill was set up in 1855 at Risra near Kolkata. In 1874, India's first blast furnace was established at Kulti in West Bengal for making iron ore, which later closed but was restarted in 1881. In 1907, Jamshedji Tata launched the Tata Iron and Steel Company (TISCO) at Jamshedpur, opening new opportunities for India.
In simple words: Early Indian industries included a failed iron melting plant in 1853, the first cotton textile industry in 1854, a jute mill in 1855, and a blast furnace in 1874 that restarted in 1881. Tata Steel began in 1907.

Question 3. How do industries pollute the environment? Explain. What are its effects?
Answer: There is no doubt that industries form the base of our economy. We cannot imagine a nation without industries. However, the downside is that industries have increased pollution, harming the environment. Environmental degradation refers to the reduced environmental quality caused by human-induced factors. Industries mainly cause four types of pollution: 1. Air pollution, 2. Water pollution, 3. Land pollution and 4. Noise pollution. Effect of Industrial pollution: Industries have severely polluted the air and water. The air has become polluted due to very harmful gases like carbon monoxide and sulphur dioxide that industries release. Many factories break rules and discharge their industrial waste into rivers, lakes, and streams, greatly polluting the water. The sound of machines causes noise pollution. Noise pollution is one reason for hearing loss in older machinery in industries, and means of transportation also create a lot of noise.
In simple words: Industries are vital for the economy but cause much pollution. Environmental degradation happens due to human activity, leading to four types of pollution: air, water, land, and noise. Air pollution comes from harmful gases like carbon monoxide. Water pollution results from factories dumping waste. Noise pollution from machines can cause hearing problems.
