ICSE Class 10 · Geography · Chapter 16
What this chapter covers
- Manufacturing and industry
- Importance of manufacturing industries
- Classification of industries
- Agro-based industries
- The sugar industry
- The cotton textile industry
- The silk textile industry
- Comparing the sugar, cotton and silk industries
- Common mistakes to avoid
Key points
- Manufacturing changes raw materials into more valuable finished goods; it is a secondary activity.
- Manufacturing adds value, supports agriculture, creates jobs, saves and earns foreign exchange, and spreads development to backward regions.
- By size, industries are large scale, small scale and cottage; by raw material, agro-based and mineral-based; by ownership, public and private sector, with joint and cooperative sectors as well.
- Agro-based industries obtain their raw materials from agriculture; sugar, cotton textile and silk are the main examples in the syllabus.
- Sugarcane is weight-losing and perishable, so sugar mills are located in cane-growing areas and must crush cane within about 24 hours.
- Sugar is made by crushing, clarification, evaporation, crystallisation and centrifuging; bagasse, molasses and press mud are its by-products.
- Uttar Pradesh and Maharashtra lead in sugar; the industry has shifted south because of higher yield, higher sucrose, a longer crushing season and cooperative mills.
- Problems of the sugar industry include low yield, a short season, old mills, high costs, late payment to farmers and heavy water use.
- The cotton textile industry is India's largest and oldest industry, working in the mill, powerloom and handloom sectors.
- Cotton is a pure raw material, so mills can locate in markets and ports; Mumbai grew because of cotton, humid climate, port, power, labour and capital.
- Maharashtra, Gujarat and Tamil Nadu lead in cotton textiles; Ahmedabad is the Manchester of India and Coimbatore the Manchester of South India.
- Grid power, railways and humidifiers led to the decentralisation of the cotton textile industry.
- Sericulture is the rearing of silkworms for raw silk; India produces mulberry, tasar, eri and muga silk and is second only to China.
- Karnataka leads in mulberry silk, Assam in muga and eri, and Jharkhand in tasar; Varanasi, Kanchipuram and Bhagalpur are famous weaving centres.
Questions answered
Define manufacturing and give one example of a raw material being turned into a finished product.
Manufacturing is the process of changing raw materials into more valuable finished goods, by hand or with machines. A sugar mill, for example, turns sugarcane into sugar.
Give four reasons why manufacturing industries are important for India.
They add value to raw materials, support agriculture by buying its produce, create employment, reduce imports and earn foreign exchange, and help balanced regional development.
Distinguish between large-scale and small-scale industries with one example of each.
A large-scale industry needs huge capital, many workers and heavy machinery, such as a sugar mill or steel plant. A small-scale industry needs little capital and few workers, such as a powerloom or soap-making unit.
What are agro-based industries? Name three.
Agro-based industries are industries that obtain their raw materials from agriculture. Sugar, cotton textile and silk industries are examples.
Distinguish between public sector and private sector industries.
Public sector industries are owned and managed by the government, such as the SAIL plant at Rourkela. Private sector industries are owned by individuals or companies, such as Tata Steel at Jamshedpur.
Why are sugar mills located close to the sugarcane fields?
Cane is weight-losing, giving only about 10 per cent of its weight as sugar, and perishable, losing sucrose within about a day of cutting. Carrying it far would be costly and would reduce the sugar recovered.
Name three by-products of the sugar industry and give one use of each.
Bagasse is used as fuel and for making paper; molasses is used to make alcohol and ethanol; press mud is used as fertiliser.
Give four reasons for the shift of the sugar industry from north India to the peninsular states.
Higher yield of cane per hectare, higher sucrose content, a longer crushing season because of the tropical climate, and well-run cooperative mills.

(a) Small-scale industries play a vital role in fostering economic development in India. Give a reason to support this statement. (b) State one difference between small-scale and large-scale industries.
Show answer
(a) Any one: they provide employment to skilled and unskilled workers; they need little capital; they contribute to national income; they boost exports.
(b) Small-scale industries need less capital and fewer workers, while large-scale industries need huge capital investment, employ large numbers of workers and produce goods on a large scale.

- Jute industry
- Cotton textile industry
- Sugar industry
Show answer
Sugar industry
ICSE 2026 sample paper · 2 marks
Explain any two ways in which cotton textile industry is important for the Indian economy.
Show answer
Any two: it earns valuable foreign exchange through exports; it provides employment to millions of people; it helps decentralisation of industry (mills and handlooms spread across the country); it meets the large domestic demand for cotton clothes in a tropical country.

Give one geographical reason to explain each of the following: (a) Work in sugar mills is a seasonal activity. (b) The cotton textile industry is widely distributed in India. (c) Vishakhapatnam steel plant has a unique locational advantage that enables it to procure raw materials easily and market the finished products with ease.
Show answer
(a) Sugarcane is harvested only in one season (about November to April) and has to be crushed within 24 hours of cutting before its sucrose content falls, so mills work only during the crushing season.
(b) Cotton is a pure (non weight-losing) raw material that is easy to transport, and cotton cloth is in demand everywhere; with cheap labour, power and markets available in many places, mills have come up all over India.
(c) It is a coastal (shore-based) plant beside Visakhapatnam port, so it can import coking coal and export finished steel by sea, while iron ore comes by rail from Bailadila.

Mention two points of difference between Small scale and Large scale industry.
Show answer
(1) Small-scale industries need less capital investment, whereas large-scale industries need huge capital investment.
(2) Small-scale industries employ fewer workers and produce goods in smaller quantities, whereas large-scale industries employ a large number of workers, need a large area and produce on a large scale.

Give one reason to explain each of the following: (a) Sugar production is gradually gaining importance in peninsular India. (b) Indian silk products are becoming less popular in the international market. (c) The importance of the iron and steel industry will never decline.
Show answer
(a) Peninsular India has a tropical climate giving higher sugar content and a longer crushing season; mills are modern and run largely in the cooperative sector near the plantations. (Any one)
(b) The high price of Indian silk (competition from cheaper silk and synthetic fibres from other countries).
(c) It is a basic industry: its products are needed by almost all other industries — machinery, railways, construction, automobiles, ships and infrastructure.

Classify industries on the basis of their size giving a suitable example for each.
Show answer
On the basis of size, industries are:
1. Large-scale industries — need huge capital, many workers and large output, e.g. iron and steel industry (Tata Steel, Jamshedpur), cotton textile mills.
2. Small-scale industries — need little capital and few workers, e.g. handloom weaving, pottery, footwear, toys (cottage industries are the smallest, run by the family at home).
