Class 12 : Grography (English) – Lesson 15.Transport and Communication
EXPLANATION & SUMMARY
🌍 Introduction
🔵 Transport and communication are vital lifelines of modern civilization.

📚 Summary (≈300 words)
Transport is the movement of goods and people via land (road, rail), water, air, and pipelines.
Communication transmits messages through personal and mass media.
Land transport is vital for internal trade; roadways offer flexibility, railways handle bulk goods.
Water transport is the cheapest for international trade; air transport is fastest for global connectivity.
Pipelines ensure continuous and eco-friendly movement of oil and gas.
Modern communication (internet, mobile, satellite) connects every corner of the world.
Both systems are crucial for economic growth, cultural exchange, and national integration.
Challenges: uneven development, congestion, environmental impact, digital divide.
Solutions: modern technology, balanced regional planning, and sustainable policies.
📝 Quick Recap
✔️ Transport = movement; Communication = message exchange.
✔️ Types of transport: land, water, air, pipelines.
✔️ Communication: personal & mass.
✔️ Both promote globalization and development.
✔️ Need for sustainability and equitable access.
