Introduction to NCERT Class 8 Geography Industries Chapter 4

Welcome to the interesting world of industries as explored in Class 8 Geography Industries Chapter 4. In this chapter, we will delve into the fascinating kingdom of industrialisation, exploring how raw materials are transformed into valuable products, the different types of industries, and the factors influencing their location. Join us on a journey to understand the significance of industries in our daily lives and their impact on global development. 

Overview

Have you ever wondered about the journey of the notebook you use every day? From its origins as part of a tree to its final form in your hands, each step involves a fascinating process of manufacturing. Let’s explore how raw materials are transformed into products of greater value through secondary activities or manufacturing.

The notebook begins its life as part of a tree:
РThe tree is cut down and transported to a pulp mill. 
– At the mill, the wood is processed into wood pulp.

Paper Production:  
РWood pulp is mixed with chemicals to create paper.  
– Machines transform the pulp into paper sheets.

Printing Process: 
– The paper is sent to a press, where lines are printed using chemical ink.

Notebook Assembly:
РPrinted pages are bound together to form a notebook.  
– The notebooks are packaged and sent to the market for sale.

Value Addition in Manufacturing:
РSecondary activities add value to raw materials.  
– Paper and notebooks are examples of value-added products.

Industry and Economic Activity:
– Industry encompasses the production of goods, the extraction of minerals, and the provision of services.
– Examples include the iron and steel industry, the coal mining industry, and the tourism industry.
