Class 12 Geography Chapter 6 – Overview

Chapter 6, Tertiary and Quaternary Activities, deals with the service sector, which involves the commercial output of services rather than the production of tangible goods. Tertiary activities include trade and commerce (retail and wholesale trading through rural and urban marketing centres), transport (carrying people and goods over km, time and cost distance), communication (telecommunications, mass media and the internet) and a wide range of personal and professional services, of which tourism is the world’s largest in terms of registered jobs. As economies develop, employment shifts from the primary to the tertiary sector. The chapter then explains the quaternary activities (collection, production and dissemination of information; research and development) and the highest-level quinary or ‘gold-collar’ activities of policy makers, along with outsourcing/off-shoring, the rise of call centres and the KPO industry, and the uneven spread of ICT opportunities known as the digital divide.

Key Concepts & Terms

Tertiary activities: service-sector activities that involve the commercial output of services rather than the production of tangible goods; they rely on specialised skills, experience and knowledge (e.g. plumber, teacher, doctor, lawyer, cashier).

Trade and commerce: the buying and selling of items produced elsewhere, for profit, carried out at trading centres — divided into rural marketing centres (quasi-urban, with mandis serving nearby settlements) and urban marketing centres (offering widely specialised goods and services).

Retail & wholesale trading: retail trading is the sale of goods directly to consumers (stores, plus non-store forms like peddling, mail-order, vending machines and internet); wholesale trading is bulk business through intermediary merchants and supply houses, who often extend credit to retailers.

Transport & transport distance: a service by which people, materials and goods are carried from one place to another; transport distance is measured as km distance (actual route length), time distance and cost distance. Isochrone lines join places equal in travel time.

Network and accessibility: as transport develops, places link into a network of nodes (meeting points/origins/destinations) and links (roads joining two nodes); a developed network has many links, so places are well connected.

Communication: the transmission of words, messages, facts and ideas — through telecommunications, radio and television (mass media), newspapers, satellites and the internet; mobile telephony and satellites have made communication independent of transport.

Services & their levels: low-order services (grocery shops, laundries) are common and widespread; high-order services (accountants, consultants, physicians) are specialised. Tourism is the world’s largest tertiary activity in registered jobs (250 million) and revenue (about 40% of total GDP).

Quaternary activities: knowledge-oriented services involving the collection, production and dissemination of information, and research and development; an advanced form of services requiring specialised knowledge and technical skills, and can be outsourced.

Quinary activities: the highest level of decision-making and policy-making services, often called ‘gold-collar’ professions — senior business executives, government officials, research scientists, financial and legal consultants — focusing on the creation, re-arrangement and interpretation of ideas.

Outsourcing & off-shoring: outsourcing (contracting out) is giving work to an outside agency to improve efficiency and reduce costs; when work is transferred to overseas locations it is called off-shoring. Examples include IT, customer support, call centres and BPO/KPO. KPO (knowledge process outsourcing) involves highly skilled, information-driven work and is distinct from BPO.

Digital divide: the uneven distribution of opportunities from ICT-based development across the globe and within countries — developed nations and metropolitan centres surge ahead while developing regions and peripheral rural areas lag behind.

NCERT Exercise — Full Solutions

All questions below are reproduced verbatim from the NCERT textbook’s end-of-chapter Exercises. Answers are original, written in exam-ready style.

1. Choose the right answer from the four alternatives given below.

(i) Which one of the following is a tertiary activity? (a) Farming    (b) Trading    (c) Weaving    (d) Hunting

ANSWER(b) Trading. Trading is a service-sector (tertiary) activity, while farming and hunting are primary activities and weaving is a secondary (manufacturing) activity.

(ii) Which one of the following activities is NOT a secondary sector activity? (a) Iron Smelting    (b) Catching fish    (c) Making garments    (d) Basket Weaving

ANSWER(b) Catching fish. Catching fish is a primary activity (it directly uses natural resources), whereas iron smelting, making garments and basket weaving all process raw materials and are secondary activities.

(iii) Which one of the following sectors provides most of the employment in Delhi, Mumbai, Chennai and Kolkata. (a) Primary    (b) Quaternary    (c) Secondary    (d) Service

ANSWER(d) Service. In large metropolitan cities the service (tertiary) sector — trade, transport, communication and other services — provides most of the employment.

(iv) Jobs that involve high degrees and level of innovations are known as: (a) Secondary activities    (b) Quaternary activities    (c) Quinary activities    (d) Primary activities

ANSWER(c) Quinary activities. Quinary activities involve the highest level of decision-making and innovation, focusing on the creation, re-arrangement and interpretation of new and existing ideas.

(v) Which one of the following activities is related to quaternary sector? (a) Manufacturing computers    (b) Paper and Raw pulp production    (c) University teaching    (d) Printing books

ANSWER(c) University teaching. University teaching is a knowledge-based service (quaternary activity), while manufacturing computers, paper/pulp production and printing books are secondary activities.

(vi) Which one out of the following statements is not true? (a) Outsourcing reduces costs and increases efficiency. (b) At times engineering and manufacturing jobs can also be outsourced. (c) BPOs have better business opportunities as compared to KPOs. (d) There may be dissatisfaction among job seekers in the countries that outsource the job.

ANSWER(c) BPOs have better business opportunities as compared to KPOs. This statement is not true. KPO (knowledge process outsourcing) involves highly skilled workers and information-driven work, enabling companies to create additional business opportunities; it is regarded as a more advanced and higher-value step than BPO.

2. Answer the following questions in about 30 words.

(i) Explain retail trading service.

ANSWERRetail trading is the business activity concerned with the sale of goods directly to consumers. Most retail trade takes place in fixed stores, while street peddling, handcarts, mail-order, vending machines and the internet are forms of non-store retailing.

(ii) Describe quaternary services.

ANSWERQuaternary services are knowledge-oriented services involving the collection, production and dissemination of information, centred around research and development. They are an advanced form of services requiring specialised knowledge and technical skills, and like other services they can be outsourced.

(iii) Name the fast emerging countries of medical tourism in the world.

ANSWERIndia has emerged as the leading country of medical tourism. Other fast-emerging countries of medical tourism are Thailand, Singapore and Malaysia, which offer world-class treatment at lower cost to overseas patients.

(iv) What is digital divide?

ANSWERThe digital divide is the uneven distribution of opportunities arising from ICT-based development. Developed countries and metropolitan centres surge ahead in connectivity and access, while developing countries and peripheral rural areas lag behind.

3. Answer the following questions in not more than 150 words.

(i) Discuss the significance and growth of the service sector in modern economic development.

ANSWER The service (tertiary) sector involves the commercial output of services rather than the production of tangible goods, relying on the specialised skills, experience and knowledge of workers. It includes trade and commerce, transport, communication and a wide range of personal and professional services such as health, education, law, governance and recreation. Significance: services overcome distance (transport, communication), facilitate the production, distribution and consumption of goods, and meet people’s daily and specialised needs. They generate large-scale employment — today most people are service workers — and activities like tourism have become the world’s single largest tertiary activity in registered jobs and revenue. Growth: in the early stages of development most people worked in the primary sector, but in a developed economy the majority of workers find employment in tertiary activity, with a moderate share in the secondary sector. Employment in services has been steadily increasing, while it has remained unchanged or declined in the primary and secondary sectors — making the service sector the basis for modern economic growth.

(ii) Explain in detail the significance of transport and communication services.

ANSWER Transport is a service by which people, materials and manufactured goods are physically carried from one location to another. It is an organised industry created to satisfy the basic human need of mobility, and modern society needs speedy, efficient transport to assist in the production, distribution and consumption of goods. At every stage the value of materials is significantly enhanced by transportation. Transport distance can be measured as km distance, time distance or cost distance, and developed networks of nodes and links keep places well connected. Communication services involve the transmission of words, messages, facts and ideas. Earlier, communication depended on means of transport, which is why all forms of transport are called lines of communication. Developments such as telecommunications, mobile telephony and satellites have made communication direct, instantaneous and largely independent of transport, reducing the time taken from weeks to minutes. Significance: together, transport and communication overcome distance, link producers and consumers, support trade and industry, spread news, knowledge and entertainment through mass media, and bind regions and nations together — making them vital to the working of a modern economy.

Extra Practice Questions

Short Answer Type Questions

Q1. What is the main difference between secondary and tertiary activities?

ANSWERThe main difference is that tertiary activities rely more heavily on the specialised skills, experience and knowledge of workers, whereas secondary activities depend on production techniques, machinery and factory processes to transform physical raw materials.

Q2. Distinguish between rural and urban marketing centres.

ANSWERRural marketing centres are quasi-urban centres of a rudimentary type that cater to nearby settlements, mostly through mandis and retail areas. Urban marketing centres offer widely specialised goods and services, including markets for labour, housing and professional services.

Q3. What are periodic markets?

ANSWERPeriodic markets are local markets found in rural areas without regular markets. They are held on specified dates — weekly or bi-weekly — and move from one place to another, so shopkeepers stay busy on all days while serving a large area.

Q4. What are isochrone lines?

ANSWERIsochrone lines are lines drawn on a map to join places that are equal in terms of the time taken to reach them. They are useful because, in selecting a mode of transport, distance in terms of time or cost is often the determining factor.

Q5. What is medical tourism?

ANSWERMedical tourism is when medical treatment is combined with international tourism activity. Patients travel abroad for affordable, world-class treatment; India is the leading country of medical tourism, along with Thailand, Singapore and Malaysia.

Long Answer Type Questions

Q1. Explain the factors that affect transport and the ways in which transport distance is measured.

ANSWERThe demand for transport is influenced by the size of population — the larger the population, the greater the demand. Transport routes depend on the location of cities, towns, villages, industrial centres and raw materials, the pattern of trade between them, the nature of the landscape, the type of climate, and the funds available to overcome obstacles along the route. Transport distance can be measured in three ways: km distance, the actual length of the route; time distance, the time taken to travel a particular route; and cost distance, the expense of travelling on a route. In choosing a mode of transport, distance in terms of time or cost is the determining factor, and isochrone lines are drawn on maps to join places equal in travel time. As transport systems develop, places link into networks of nodes and links, and a network with many links indicates well-connected places.

Q2. Describe outsourcing, off-shoring and the growth of the KPO industry, with the new trends in quinary services.

ANSWEROutsourcing, or contracting out, means giving work to an outside agency to improve efficiency and reduce costs. When outsourcing involves transferring work to overseas locations it is called off-shoring, though both terms are often used together. Business activities that are outsourced include information technology (IT), human resources, customer support and call-centre services, and at times manufacturing and engineering. Outsourcing has led to the opening of many call centres in India, China, Eastern Europe, Israel, the Philippines and Costa Rica, creating new jobs in countries where cheap and skilled workers are available. The main reason for continuing outsourcing is comparative advantage — lower wages and overhead costs make it profitable to get job-work done overseas. New trends in quinary services include knowledge process outsourcing (KPO) and home-shoring (an alternative to outsourcing). KPO is distinct from BPO because it involves highly skilled, information-driven knowledge work that creates additional business opportunities; examples include research and development, e-learning, business research, intellectual property research, the legal profession and the banking sector.

Q3. Discuss tourism as a tertiary activity, explaining its importance and the main tourist attractions.

ANSWERTourism is travel undertaken for purposes of recreation rather than business. It has become the world’s single largest tertiary activity in terms of total registered jobs (about 250 million) and total revenue (around 40 per cent of total GDP). Many local people are employed to provide services such as accommodation, meals, transport, entertainment and special shops, and tourism fosters the growth of infrastructure industries, retail trading and craft industries. In some regions tourism is seasonal, depending on favourable weather, while others attract visitors all year round. The main tourist attractions are: climate — people from colder regions seek warm, sunny weather (as in Southern Europe and the Mediterranean) or snow cover for skiing; landscape — attractive mountains, lakes and sea coasts; history and art — ancient towns, archaeological sites, castles, palaces and churches; and culture and economy — ethnic and local customs and low costs, with home-stays such as heritage homes in Goa and Coorg emerging as profitable businesses.

Exam Tips & Common Mistakes

How to score full marks in this chapter

Be clear about the sector hierarchy: primary, secondary, tertiary, quaternary and quinary — and be able to classify examples (trading is tertiary, university teaching is quaternary, policy-making is quinary). Memorise the three measures of transport distance (km, time, cost) and the meaning of nodes, links and isochrone lines. For long answers on services, transport, communication, tourism and outsourcing, use the textbook’s own facts — tourism’s 250 million jobs and ~40% of GDP, India as the leader in medical tourism, the difference between BPO and KPO, and the meaning of off-shoring and the digital divide.

Common mistakes to avoid

  • Calling trading a secondary activity — trade and commerce are tertiary (service) activities.
  • Confusing quaternary (information and R&D) with quinary (highest-level decision-making) activities.
  • Thinking BPO has better business opportunities than KPO — KPO involves higher-skilled, information-driven work.
  • Mixing up outsourcing (contracting out work) with off-shoring (transferring it overseas).
  • Confusing retail trading (sale to consumers) with wholesale trading (bulk business through intermediaries).
  • Assuming the digital divide exists only between countries — it also exists within countries.

Frequently Asked Questions

What is Chapter 6 of Class 12 Geography (Fundamentals of Human Geography) about?
