Class 12 Geography Chapter 7 – Overview

Chapter 7, Transport and Communication, studies the means that move goods, people and ideas from the place of their production to the place of their use. Under land transport, India has one of the largest road networks in the world (about 62.16 lakh km), classified as National Highways, State Highways, District Roads and Rural Roads, supported by projects like the Golden Quadrilateral, the North–South and East–West Corridors and Bharatmala Pariyojana. Indian Railways, introduced in 1853 (Bombay to Thane), is divided into 17 zones and carries both freight and passengers on broad, metre and narrow gauge. Water transport is the cheapest mode, split into inland waterways (National Waterways) and oceanic routes served by 12 major ports. Air transport is the fastest mode, while oil and gas pipelines move liquids and gases efficiently over long distances. The chapter closes with communication networks — personal (internet), mass (radio, television) and satellite (INSAT and IRS) — that have revolutionised the exchange of information.

Key Concepts & Terms

Transport: the means by which material goods, commodities and people are carried from the site of production or availability to the place of use or consumption.

Communication: the process of exchanging ideas, views and messages from one place or individual to another; modern means include post, telegraph, telephone, internet and satellites.

National Highways (NH): main roads built and maintained by the Central Government for inter-state transport and the movement of defence men and material; they are only about 2 per cent of total road length but carry about 40 per cent of road traffic. NHAI (1995) develops and maintains them.

Golden Quadrilateral: a 5,846-km, 4/6-lane high-density corridor connecting Delhi, Mumbai, Chennai and Kolkata.

North–South & East–West Corridors: N–S connects Srinagar to Kanniyakumari (with Cochin–Salem spur); E–W connects Silchar (Assam) to Porbandar (Gujarat).

Railway gauges: broad gauge (1.676 m), metre gauge (1 m) and narrow gauge (0.762 m or 0.610 m, mostly in hilly areas). The railway system is divided into 17 zones.

National Waterways (NW): inland water routes declared for development — e.g. NW 1 (Prayagraj–Haldia on the Ganga), NW 2 (Sadiya–Dhubri on the Brahmaputra), NW 3 (Kottapuram–Kollam, West Coast Canal).

Oceanic routes: sea routes along India’s 7,517-km coastline served by 12 major and about 200 minor ports; about 95 per cent of foreign trade by volume moves through them.

Pipelines: the most convenient mode for moving liquids and gases (and slurry) over long distances; key examples are the OIL Naharkatiya–Barauni–Kanpur pipeline and the GAIL Hazira–Vijaipur–Jagdishpur (HVJ) gas pipeline.

Satellite systems: INSAT (1983) for telecommunication and meteorology, and IRS (operational from 1988) for remote sensing of natural resources; NRSC at Hyderabad processes the data.

(i) In how many zones has the Indian Railways system been divided? (a) 9    (b) 12    (c) 17    (d) 14

ANSWER (c) 17. Because of its very large size, the Indian Railways network is managed by dividing it into 17 zones, each with its own headquarters (for example, Northern Railway at New Delhi and Central Railway at Mumbai CST).

(ii) On which river and between which two places does the National Water Way No. 1 lie? (a) The Brahmaputra, Sadiya-Dhubri (b) The Ganga, Haldia–Prayagraj (c) West Coast Canal, Kottapuram to Kollam (d) Godavari–Kakinada Puducherry

ANSWER (b) The Ganga, Haldia–Prayagraj. National Waterway No. 1 lies on the Ganga along the Prayagraj–Haldia stretch (1,620 km), one of the most important waterways in India, navigable by mechanical boats up to Patna.

(iii) In which of the following year, the first radio programme was broadcast? (a) 1911    (b) 1936    (c) 1927    (d) 1923

ANSWER (d) 1923. Radio broadcasting started in India in 1923 by the Radio Club of Bombay. It was later brought under government control as the Indian Broadcasting System (1930), renamed All India Radio (1936) and Akashwani (1957).

2. Answer the following questions in about 30 words.

(i) Which activity does transportation convey? Name three major modes of transportation.

ANSWER Transportation conveys the movement of goods, commodities and people from the place of their production or availability to the place of their use or consumption. Three major modes are land transport (roads and railways), water transport and air transport.

(ii) Discuss advantages and disadvantages of pipeline transportation.

ANSWER Advantages: pipelines are the most convenient and efficient way to move liquids and gases (and even solids as slurry) over long distances; they involve low running cost, minimal loss in transit and continuous, weather-proof supply. Disadvantages: they have a very high initial cost of construction, are difficult to repair, cannot be shifted once laid, and leakages are hard to detect.

(iii) What do you mean by ‘communication’?

ANSWER Communication means the exchange of ideas, views and messages from one place to another or from one individual to another. Human beings use various means — post, telegraph, telephone, internet and satellites — to convey messages quickly and easily.

3. Answer the following questions in about 150 words.

(i) Which are the chief means of transportation in India? Discuss the factors affecting their development.

ANSWER The chief means of transportation in India are roads, railways, waterways (inland and oceanic), airways and pipelines. Roads carry about 85 per cent of passenger and 70 per cent of freight traffic and are best for shorter distances; railways form one of the longest networks in the world, carrying bulk freight and passengers over long distances; waterways are the cheapest mode for heavy, bulky cargo; airways are the fastest; and pipelines efficiently move oil and gas. Factors affecting their development: (1) Physical relief and terrain — plains favour dense road and rail networks, while hilly, plateau and forested areas have sparse, poor-quality routes. (2) Climate — heavy snowfall and rain (as on the Srinagar–Leh highway) disrupt traffic. (3) Level of economic and industrial development — resource-rich and industrial regions and urban centres attract better networks. (4) Population and urbanisation — dense, urban areas demand more transport. (5) Technology and finance, and (6) government policy (road plans, NHAI projects, Konkan Railway) all shape their growth.

(ii) Give a detailed account of the development of railways in India and highlight their importance.

ANSWER Development: Indian Railways was introduced in 1853, when the first line was constructed from Bombay to Thane, covering 34 km. It is now the largest government undertaking in the country, with a network of about 67,956 km (Railway Year Book 2019–20) and one of the longest railway systems in the world. Because of its very large size, the system is divided into 17 zones for efficient management. On the basis of track width, lines are of three gauges — broad gauge (1.676 m), metre gauge (1 m) and narrow gauge (0.762 m or 0.610 m). Railways have launched a programme to convert metre and narrow gauges to broad gauge, replaced steam engines with diesel and electric ones (raising speed, haulage capacity and improving the environment), and built engineering marvels like the Konkan Railway (1998) linking Mumbai and Mangaluru along the western coast. Importance: Railways facilitate the long-distance movement of both freight and passengers, contribute to the growth of the economy, integrate the country, support industry and agriculture by carrying bulk goods cheaply, and remain the main means of transport for the masses. Mahatma Gandhi said the railways “brought people of diverse cultures together to contribute to India’s freedom struggle”.

(iii) Describe the role of roads in the economic development of India.

ANSWER India has one of the largest road networks in the world (about 62.16 lakh km), and roads play a central role in the country’s economic development. Roads carry about 85 per cent of passenger and 70 per cent of freight traffic every year and are especially suitable for shorter-distance travel, providing flexible door-to-door movement that railways cannot. Roads link farms to markets, raw-material sources to factories and goods to ports, so they support agriculture, industry and trade. National Highways connect state capitals, major cities, ports and railway junctions and ensure the movement of defence men and material in strategic areas. Rural roads (about 80 per cent of total road length), strengthened by the Pradhan Mantri Gram Sadak Yojana, provide vital connectivity to villages, opening up remote areas to markets, schools and health services. Major projects — the Golden Quadrilateral, the North–South and East–West Corridors and Bharatmala Pariyojana — reduce the time, distance and cost of movement, decongest cities and improve logistic efficiency, thereby boosting national economic growth and regional development.

Extra Practice Questions

Short Answer Type Questions

Q1. What are National Highways, and how important are they to road traffic?

ANSWERNational Highways are the main roads constructed and maintained by the Central Government for inter-state transport and the movement of defence men and material. Though they form only about 2 per cent of total road length, they carry about 40 per cent of road traffic. The NHAI (1995) develops and maintains them.

Q2. Name the three categories of railway gauges with the distance between their rails.

ANSWERThe three categories are: broad gauge, where the distance between rails is 1.676 m; metre gauge, where it is one metre; and narrow gauge, where it is 0.762 m or 0.610 m. Narrow gauge is generally confined to hilly areas.

Q3. Why is water transport considered the cheapest mode of transport?

ANSWERWater transport is the cheapest means because it needs no construction or maintenance of a track (the waterway is natural), is most suitable for carrying heavy and bulky material, and is fuel-efficient and eco-friendly. India has 14,500 km of navigable inland waterways besides its oceanic routes.

Q4. What is the Border Roads Organisation (BRO) and what does it do?

ANSWERThe BRO, established in May 1960, is a premier multifaceted construction agency that builds and maintains roads in strategically important border areas to strengthen defence and aid economic development. It constructs high-altitude mountain roads (e.g. Chandigarh–Manali–Leh), undertakes snow clearance and built the Atal Tunnel.

Q5. Distinguish between the two satellite systems used in India.

ANSWERIndia’s satellite systems are grouped into INSAT and IRS. The INSAT (Indian National Satellite System, 1983) is a multipurpose system for telecommunication, meteorological observation and broadcasting. The IRS (Indian Remote Sensing system, operational from 1988) collects data in several spectral bands for managing natural resources; the NRSC at Hyderabad processes this data.

Long Answer Type Questions

Q1. Explain the classification of India’s road network and the major road development projects.

ANSWERFor construction and maintenance, India’s roads are classified as National Highways (built by the Centre, linking state capitals, major cities, ports and junctions, carrying about 40 per cent of road traffic), State Highways (built and maintained by state governments, joining state capitals with district headquarters), Major District Roads (connecting district headquarters with other important nodes), and Rural Roads (about 80 per cent of total length, vital for village connectivity). Other roads include Border Roads and International Highways. Major development projects include the Golden Quadrilateral (5,846 km, linking Delhi–Mumbai–Chennai–Kolkata), the North–South Corridor (Srinagar to Kanniyakumari) and East–West Corridor (Silchar to Porbandar), the Pradhan Mantri Gram Sadak Yojana for rural roads, and Bharatmala Pariyojana, which develops about 26,000 km of economic corridors, ring roads, bypasses and elevated corridors to carry freight and decongest cities.

Q2. Describe the development of oil and gas pipelines in India.

ANSWERPipelines are the most convenient and efficient mode for transporting liquids and gases (and solids as slurry) over long distances. Oil India Limited (OIL), incorporated in 1959 under the Ministry of Petroleum and Natural Gas, constructed Asia’s first cross-country pipeline (1,157 km) from the Naharkatiya oilfield in Assam to Barauni refinery in Bihar, extended to Kanpur in 1966. GAIL (India) Ltd., set up in 1984 as a public-sector undertaking, transports, processes and markets natural gas. Its first major project, the 1,700-km Hazira–Vijaipur–Jagdishpur (HVJ) cross-country gas pipeline, linked the Mumbai High and Bassein gas fields with fertiliser, power and industrial complexes in western and northern India, giving a strong impetus to the gas market. India’s gas infrastructure has expanded more than ten times, from 1,700 km to about 18,500 km, and is expected to reach over 34,000 km as a National Gas Grid linking all gas sources and consuming markets, including the North-Eastern states.

Q3. Discuss the various modes of communication in India.

ANSWEROn the basis of scale and quality, communication in India is divided into personal, mass and satellite systems. Personal communication centres on the internet, the most advanced means, widely used in urban areas; it enables direct contact through e-mail, access to information, e-commerce and money transactions at low cost. Mass communication includes radio (broadcasting began in 1923, becoming All India Radio in 1936 and Akashwani in 1957) which spreads information, education and entertainment, and television, the most effective audio-visual medium, which began in 1959, was delinked from AIR as Doordarshan in 1976 and, after INSAT, started Common National Programmes for remote rural areas. Satellite communication (INSAT for telecommunication and meteorology, IRS for remote sensing) is vital for weather forecasting, monitoring natural calamities and border surveillance. Together these networks have revolutionised the exchange of ideas and information across the country.

Exam Tips & Common Mistakes

How to score full marks in this chapter

Memorise the key numbers — road network (62.16 lakh km), 17 railway zones, gauge distances (1.676 m / 1 m / 0.762 m), coastline (7,517 km), 12 major ports, and the road-traffic shares (85% passenger, 70% freight; NH = 2% length but 40% traffic). For 150-word answers, structure them with clear headings (development / importance, advantages / disadvantages, factors) and back each point with a textbook example such as the Golden Quadrilateral, Konkan Railway, NW 1, the HVJ pipeline, INSAT and IRS. Always name dates accurately (railways 1853, radio 1923, INSAT 1983).

Common mistakes to avoid

  • Saying Indian Railways has 16 or 18 zones — the textbook states 17 zones.
  • Confusing NW 1 (Ganga, Prayagraj–Haldia) with NW 2 (Brahmaputra, Sadiya–Dhubri).
  • Mixing up gauge widths — broad gauge is 1.676 m, not 1 m.
  • Writing 1936 for the first radio broadcast — broadcasting began in 1923; 1936 is when it became All India Radio.
  • Forgetting to give both advantages and disadvantages when the question asks for both (pipelines).
  • Confusing INSAT (telecommunication/meteorology) with IRS (remote sensing of resources).
