1. What the board examines
In the CBSE board exam this chapter is examined only through map work: locating and labelling the ten major sea ports and six international airports below. The rest of the chapter (roadways, railways, pipelines, waterways, airways, communication, trade and tourism) is assessed through the interdisciplinary project; sections 4 and 5 of these notes support that project.
Most of India's foreign trade by volume moves through its sea ports; each port serves a hinterland, the inland area whose goods pass through it. International airports carry passengers and light, valuable or urgent cargo.
| Part | How assessed |
|---|---|
| Major sea ports and international airports (map work) | Board exam |
| Transport, communication and trade | Interdisciplinary project |
Key terms
- Hinterland
The inland area whose goods are shipped through a particular port.
- Major port
A large port administered as a major port, handling most of the country's sea trade.
2. Major sea ports (board map list)
West coast, north to south
- Kandla (Deendayal Port), Gujarat: a tidal port at the head of the Gulf of Kachchh, developed after independence to replace Karachi (which went to Pakistan) and serve north-western India.
- Mumbai, Maharashtra: the biggest port, with a large, naturally sheltered harbour.
- Marmagao, Goa: on the Zuari estuary; the main iron-ore exporting port of Goa.
- New Mangalore, Karnataka: exports iron-ore concentrate from the Kudremukh area.
- Kochi, Kerala: in the extreme south-west, at the entrance of a lagoon, with a natural harbour.
East coast, south to north
- Tuticorin (V. O. Chidambaranar Port), Tamil Nadu: in the extreme south-east; natural harbour; trade with Sri Lanka and the Maldives.
- Chennai, Tamil Nadu: one of the oldest artificial ports, on the straight Coromandel coast.
- Visakhapatnam, Andhra Pradesh: the deepest harbour almost enclosed by land (landlocked), sheltered by hills, first built for iron-ore exports.
- Paradip, Odisha: near the Mahanadi delta; known for shipping iron ore.
- Haldia, West Bengal: a subsidiary port on the Hugli estuary, developed to relieve Kolkata, an inland river port that silt makes hard for large ships to reach.
| Port | State | Clue |
|---|---|---|
| Kandla | Gujarat | Tidal; head of Gulf of Kachchh |
| Mumbai | Maharashtra | Biggest; natural harbour |
| Marmagao | Goa | Zuari; iron ore |
| New Mangalore | Karnataka | Kudremukh ore |
| Kochi | Kerala | Lagoon |
| Tuticorin | Tamil Nadu | Extreme south-east |
| Chennai | Tamil Nadu | Old artificial port |
| Visakhapatnam | Andhra Pradesh | Deepest landlocked |
| Paradip | Odisha | Mahanadi delta; iron ore |
| Haldia | West Bengal | Subsidiary to Kolkata |
Key terms
- Tidal port
A port where ship movements depend on the rise and fall of the tide, such as Kandla.
- Artificial harbour
A harbour created by building breakwaters on an open coast, such as Chennai.
- Landlocked harbour
A harbour almost enclosed by land, giving very sheltered water, such as Visakhapatnam.
3. International airports (board map list)
- Amritsar (Punjab): Sri Guru Ram Dass Jee International Airport, earlier known as Raja Sansi; near the Pakistan border.
- Delhi: Indira Gandhi International Airport.
- Mumbai (Maharashtra): Chhatrapati Shivaji Maharaj International Airport.
- Chennai (Tamil Nadu): Chennai International Airport at Meenambakkam.
- Kolkata (West Bengal): Netaji Subhas Chandra Bose International Airport.
- Hyderabad (Telangana): Rajiv Gandhi International Airport.
Mumbai and Chennai are both major sea ports and international airports; Kolkata's port on the list is Haldia.
| City | Airport |
|---|---|
| Amritsar | Sri Guru Ram Dass Jee (Raja Sansi) |
| Delhi | Indira Gandhi |
| Mumbai | Chhatrapati Shivaji Maharaj |
| Chennai | Meenambakkam |
| Kolkata | Netaji Subhas Chandra Bose |
| Hyderabad | Rajiv Gandhi |
Key terms
- International airport
An airport with customs and immigration facilities for flights to and from other countries.
4. Transport (project topic)
Not assessed in the board exam; for the interdisciplinary project.
- Roadways: door-to-door service, cheaper to build than railways, suit hilly terrain and short distances. Golden Quadrilateral super highways link Delhi–Kolkata–Chennai–Mumbai; the North–South corridor joins Srinagar and Kanyakumari, the East–West corridor joins Silchar (Assam) and Porbandar (Gujarat). Types: national highways, state highways (state PWDs), district roads (Zila Parishads), other rural roads, border roads (Border Roads Organisation, 1960), international highways.
- Railways: the main carrier of bulky goods and long-distance passengers; gauges broad 1.676 m, metre 1 m, narrow 0.762 m and 0.610 m; dense in the northern plains; difficult in the Himalayas, deserts and swampy areas.
- Pipelines: crude oil, petroleum products and gas from fields to refineries, fertiliser and power plants (e.g. the Hazira–Vijaipur–Jagdishpur gas pipeline); high initial cost, low running cost, no transshipment losses or delays.
- Waterways: cheapest, fuel-efficient and environment-friendly for heavy cargo. NW 1: Ganga, Prayagraj (Allahabad)–Haldia; NW 2: Brahmaputra, Sadiya–Dhubri; NW 3: West Coast Canal in Kerala, Kottapuram–Kollam (with Udyogamandal and Champakkara canals).
- Airways: fastest, most comfortable; reach mountains, deserts, forests and the north-east; Pawan Hans Helicopters Ltd. serves ONGC offshore operations and remote areas.
| Mode | Advantage | Limitation |
|---|---|---|
| Road | Door to door | Congestion |
| Rail | Bulky, long distance | Difficult terrain |
| Pipeline | Low running cost | High initial cost |
| Water | Cheapest | Slow; needs depth |
| Air | Fastest | Costly |
Key terms
- Golden Quadrilateral
Six-lane super highways joining Delhi, Kolkata, Chennai and Mumbai.
- Transshipment
Moving cargo from one vehicle or mode to another during a journey.
- National waterway
A river or canal stretch developed for navigation and declared of national importance.
5. Communication, trade and tourism (project topic)
Not assessed in the board exam; for the interdisciplinary project.
- Postal network: first-class mail (cards, envelopes) is airlifted between stations; second-class mail (book packets, registered newspapers, periodicals) goes by surface transport; special mail channels speed delivery in towns and cities.
- Telecommunication connects cities and villages; mass communication (radio, television, newspapers, magazines, films) informs, educates and entertains; films are certified before release.
- Trade: the exchange of goods between people, states and countries. Balance of trade = exports − imports; favourable when exports exceed imports, unfavourable when imports exceed exports.
- Tourism: promotes national integration, supports handicrafts and cultural pursuits, and earns foreign exchange.
Key terms
- Balance of trade
The difference between the value of a country's exports and imports.
- Favourable balance
When the value of exports is greater than the value of imports.
Exam tips
Common mistakes (map work)
- Placing New Mangalore in Kerala (it is in Karnataka) or Tuticorin in Kerala (it is in Tamil Nadu).
- Marking Kolkata instead of Haldia for the port on the list.
- Putting Kandla in the Gulf of Khambhat instead of the Gulf of Kachchh.
- Dots inland for ports or in the sea for airports.
How marks are awarded
- One mark per place: correct location, clear dot, correct name (either current or older name accepted, e.g. Kandla or Deendayal Port).
- Source questions on this chapter ask you to identify ports from clues; use the clue table in section 2.
- Transport, communication and trade are assessed through the project, not the board paper.
