📝 Note on Chapter Numbering
In the NCERT Geography textbook, this is "Chapter 4". However, in our SST sequence, it is listed as Chapter 13.

📖 PART 1: What is an Industry?

Industry refers to an economic activity that is concerned with production of goods (e.g., steel industry), extraction of minerals (e.g., coal mining), or the provision of services (e.g., tourism industry). Secondary activities (manufacturing) change raw materials into products of more value to people.

As paper made from pulp and cloth made from cotton have had value added to them at each stage of the manufacturing process, the finished product has more value and utility than the raw material it is made from.

🏭 PART 2: Classification of Industries

Types of Industries

Industries can be classified on the basis of raw materials, size, and ownership.

1. Based on Raw Materials

Classification Source of Raw Material Examples
Agro-based Industries Plant and animal-based products (agriculture). Food processing, vegetable oil, cotton textile, dairy products, leather industries.
Mineral-based Industries Mineral ores (heavy machinery, building materials). They are primary industries that feed other industries. Iron and Steel industry. (Iron made from iron ore is used for heavy machinery, railway coaches).
Marine-based Industries Products from the sea and oceans. Manufacturing fish oil, processing sea food.
Forest-based Industries Forest produce. Pulp and paper, pharmaceuticals, furniture, buildings.

2. Based on Size

Size refers to the amount of capital invested, number of people employed, and the volume of production.

3. Based on Ownership

📍 PART 3: Factors Affecting Location of Industries

The factors affecting the location of industries are the availability of raw material, land, water, labour, power, capital, transport, and market.

⚠️ PART 4: Industrial Disasters

The Bhopal Gas Tragedy (1984)
One of the worst industrial disasters of all time occurred in Bhopal on 3 December 1984. Highly poisonous Methyl Isocyanate (MIC) gas along with Hydrogen Cyanide leaked from the Union Carbide pesticide factory. Thousands died, and many more suffered from blindness, impaired immune systems, and neurological disorders. This highlights the need for strict risk reduction measures around industrial areas.

⚙️ PART 5: Major Industries of the World

The world's major industries are the iron and steel industry, the textile industry, and the information technology (IT) industry. The first two are older, while IT is an emerging "sunrise" industry.

Iron and Steel Industry

This is a feeder industry whose products are used as raw materials for other industries. The inputs for the industry include raw materials such as iron ore, coal, and limestone, along with labour, capital, site, and infrastructure.
