Focused last-minute revision with clear concepts, high-yield comparisons, diagrams, exam traps and compact practice.
Chapter Snapshot
- Industry converts raw materials into more useful goods or provides specialised services.
- Industries can be classified by raw material, size and ownership.
- Location depends on raw materials, power, labour, capital, transport, market and government policies.
- An industrial system has inputs, processes and outputs.
- Industrial regions develop where several favourable factors combine.
- Industrial growth must be managed to reduce air, water, land and noise pollution.
What You Will Learn

Last-Minute Chapter Map
Revise this chapter in three passes:
- Understand the key geographical idea.
- Memorise comparisons, terms and cause–effect links.
- Attempt the compact questions without looking at the answers.
1. Meaning of Industry
2. Classification by Raw Material
Agro-based industries use agricultural products, such as cotton textiles and sugar. Mineral-based industries use mineral ores and rocks, such as iron and steel. Marine-based industries use products from seas and oceans. Forest-based industries use forest products such as timber and pulp.
3. Classification by Size and Ownership
By size, industries may be small-scale or large-scale according to investment, labour, technology and output. By ownership, they may be private-sector, public-sector, joint-sector or cooperative. The exact legal definitions of size can change, so geographical understanding should focus on relative scale and organisation.
4. Industrial Location
Industries choose locations where total costs and risks are manageable. Important factors include raw materials, land, water, labour, power, capital, transport, markets and government support. No single factor explains every industry.
5. Industrial System
Industrial activity can be viewed as a system. Inputs include raw materials, labour, capital, power and information. Processes transform inputs through manufacturing. Outputs include finished goods, income and also waste materials.
6. Industrial Regions
Industrial regions emerge when many industries cluster in one area because of transport networks, markets, skilled labour, power supply and supporting services. Examples occur around major urban-industrial belts in India and other parts of the world.
7. Iron and Steel Industry
Iron and steel is often called a basic industry because its products support machinery, construction, transport and many other industries. Location historically depended strongly on bulky raw materials such as iron ore and coal, though modern transport and technology can change this pattern.
8. Textile and Information Technology Industries
Cotton textile production may locate near raw materials, labour, markets and ports. Information-technology industries depend more strongly on skilled labour, communication networks, reliable power and urban services than on bulky raw materials.
9. Industrial Pollution
Industry can cause air, water, land and noise pollution. Control measures include cleaner fuels, treatment of wastewater, recycling, efficient machines, safe waste disposal, filters, green belts and strict environmental standards.
Industry Classification
| Basis | Types | Example |
|---|---|---|
| Raw material | Agro / Mineral / Marine / Forest | Cotton textiles / steel / fish processing / paper |
| Size | Small / Large | Workshop / large integrated plant |
| Ownership | Private / Public / Joint / Cooperative | Different management and capital structures |
Location Factors
| Factor | Why It Matters |
|---|---|
| Raw material | Supply and transport cost |
| Power | Runs machinery and processing |
| Labour | Provides skills and work force |
| Transport | Moves inputs and finished goods |
| Market | Creates demand and sales access |
| Capital | Finances land, machines and operations |
Industry works as a system of inputs, processes and outputs.

Compact Practice
Sugar industry is mainly which type by raw material?
View Solution
Agro-based
Iron and steel is commonly called what kind of industry because many others depend on it?
View Solution
Basic industry
Name four industrial-location factors.
View Solution
Any four of raw materials, labour, power, transport, market, capital, land, water and government policy.
What are the three parts of an industrial system?
View Solution
Inputs, processes and outputs.
Why can a port city attract industries even if raw materials come from far away?
View Solution
Ports and transport networks reduce import-export costs and provide access to markets and inputs.
