Chapter 7: Transport And Communication
Source: NCERT Official Textbook
The chapter systematically covers all major Modes of Transport: Land (Roads, Railways, including detailed discussions on global highways like the Pan-American and transcontinental railways like the Trans-Siberian), Water (Sea Routes like the Northern Atlantic ‘Big Trunk Route’, and vital canals like Suez and Panama, plus key inland waterways like the Rhine), Air (its speed, cost, and strategic importance, along with major inter-continental routes), and Pipelines (for uninterrupted flow of liquids/gases).
The second half focuses on Communication, tracing its evolution from the telegraph and telephone to the modern digital age. Key developments include Optic Fiber Cables (OFC), Satellite Communication (making cost invariant to distance), and the rise of Cyberspace and the Internet.
The chapter emphasizes how these technologies, more than transport, have created a ‘global village’ by enabling instant connectivity, e-commerce, and e-governance, expanding human economic and social space exponentially.
