NCERT Class 8 Geography Chapter 5: Industries Notes & Solutions

Classification of Industries: How Do We Group Them?

Industries are classified into different categories to make their study organized and logical. Under the cbse class 8 geography chapter 5 industries syllabus, we classify them based on three major criteria:

1. Raw Materials: Depending on the type of raw materials they use, industries can be Agro-based (using plant and animal products like cotton or leather), Mineral-based (using mineral ores like iron ore to make steel), Marine-based (using products from the sea like fish oil), or Forest-based (using forest wood for paper or pharmaceutical products).
2. Size: This refers to the amount of capital invested, the number of people employed, and the volume of production. It is divided into Small-scale industries (like cottage or household industries, e.g., pottery and basket weaving) and Large-scale industries (which use heavy machinery and massive capital, e.g., automobile and iron & steel manufacturing).
3. Ownership: Industries can be owned by various entities. Private Sector industries are owned by individuals or groups. Public Sector (State-owned) industries are owned by the government (e.g., Hindustan Aeronautics Limited). Joint Sector industries are jointly run by the state and individuals (e.g., Maruti Udyog). Cooperative Sector industries are owned and operated by the producers of raw materials themselves (e.g., Amul Dairy).

Step-by-Step: Factors Affecting Industrial Location

1. Availability of Raw Materials — Industries are set up close to the source of raw materials, especially if the materials are heavy or perishable. For example, iron and steel plants are always near coal and iron ore mines.
2. Power and Water Supply — Constant electricity and abundant water are crucial. Chemical and steel plants require massive amounts of water and are usually located near major rivers or lakes.
3. Labour and Capital availability — Cheap, skilled, and semi-skilled labor is needed. Industries also require massive financial investments (capital), which are usually secured from nearby banking hubs.
4. Transport Infrastructure and Markets — Excellent connectivity via roads, railways, or ports is essential to bring raw materials in and send finished goods to the markets where they will be sold.

Exam Tip: Don't Confuse Joint and Cooperative Sectors!

Many students lose marks in their CBSE exams by mixing up Joint Sector and Cooperative Sector ownership models. Remember this simple trick:

• Joint Sector: Managed by both the Government AND private business individuals together (e.g., Maruti Suzuki/Udyog Ltd).
• Cooperative Sector: Managed exclusively by the people who produce the raw materials (e.g., Anand Milk Union Limited - AMUL, or Sudha Dairy). Here, the raw material suppliers pool resources and share profits proportionally.

Practice Questions with Solutions

• Q: What are secondary activities? Explain with an example.
  A: Step 1: Define secondary activities.
  Secondary activities, or manufacturing, are processes that convert raw materials into finished products of higher value for people.
  Step 2: Provide an example.
  For example, wood pulp (a raw material from forests) is processed and converted into paper (a high-value secondary product), which is then bound into notebooks.
  Final answer: Secondary activities add value to raw materials by transforming them into usable products, such as converting raw cotton into finished garments.

• Q: Distinguish between agro-based and mineral-based industries.
  A: Step 1: Define Agro-based industries.
  Agro-based industries use plant and animal-based products as their primary raw materials. Examples include food processing, vegetable oil production, and cotton textile manufacturing.
  Step 2: Define Mineral-based industries.
  Mineral-based industries are primary industries that use mineral ores as their raw materials. The products of these industries feed other industries. An example is the Iron and steel industry.
  Final answer: Agro-based industries rely on agricultural inputs, whereas mineral-based industries process metallic and non-metallic mineral ores.

• Q: Why is the iron and steel industry often called the backbone of modern industry?
  A: Step 1: Explain the dependency of other sectors.
  Almost everything we use is either made of iron or steel, or has been made with tools and machinery made of these metals.
  Step 2: Provide specific real-life examples.
  Ships, trains, trucks, and automobiles are made largely of steel. Safety pins, needles, oil wells, and massive farm machinery all require steel.
  Final answer: Because it provides the essential tools, machinery, and structural materials required by all other industries, the iron and steel industry is considered the backbone of modern industry.

• Q: What is an industrial region? Name three major industrial regions of the world.
  A: Step 1: Define industrial regions.
  Industrial regions emerge when several industries locate close to each other to share the mutual benefits of their close proximity.
  Step 2: Identify major global industrial regions.
  Major global regions include Eastern North America, Western and Central Europe, Eastern Europe, and Eastern Asia.
  Final answer: Industrial regions are clusters of co-located industries that share resources. Examples include Eastern North America, Western Europe, and Eastern Asia.
