Exercise 2: Short Answer Questions (about 30 words)

2(i)State any three merits of roadways.Show solution
Three merits of roadways are:

1. Door-to-door service: Roads provide the advantage of door-to-door delivery of goods and passengers, which is not possible with railways or airways.

2. Construction in difficult terrain: Roads can be constructed in hilly, mountainous, and remote areas where laying railway lines is difficult and expensive.

3. Economical for short distances: Transporting goods and passengers over short distances is cheaper and more convenient by road than by any other mode of transport.
2(ii)Where and why is rail transport the most convenient means of transportation?Show solution
Rail transport is most convenient in the northern plains of India because:
- The vast level land makes construction of railway lines easy and economical.
- The high density of population and large volume of agricultural produce and goods require bulk transport over long distances.
- The extensive plain area allows a dense network of railway lines to be laid easily.
2(iii)What is the significance of the border roads?Show solution
Border roads are significant because:
- They have improved accessibility in remote and strategically important areas near international borders (e.g., in the Himalayas and North-East India).
- They are vital for the movement of defence personnel and military equipment to border areas.
- They have promoted economic development and integration of border regions with the rest of the country by connecting previously isolated areas.
2(iv)What is meant by trade? What is the difference between international and local trade?Show solution
Trade refers to the exchange (buying and selling) of goods and services between individuals, regions, or countries.

Difference between International and Local Trade:

| Basis | International Trade | Local Trade |
|---|---|---|
| Scope | Takes place between two or more countries | Takes place within a city, town, or village |
| Currency | Involves foreign exchange | Conducted in domestic currency |
| Example | India exporting software to the USA | Buying vegetables in a local market |

Local trade is conducted within a limited area, while international trade crosses national boundaries.

Exercise 3: Long Answer Questions (about 120 words)

3(i)Why are the means of transportation and communication called the lifelines of a nation and its economy?Show solution
Given: The role of transportation and communication in a nation's economy.

Answer:

Means of transportation and communication are called the lifelines of a nation and its economy because of the following reasons:

1. Movement of goods and people: Transportation networks (roads, railways, airways, waterways) carry raw materials from production centres to factories and finished goods from factories to markets. Without this, economic activity would come to a standstill.

2. Integration of markets: They link different regions of the country, integrating local, regional, and national markets. This ensures that goods produced in one part of the country are available in other parts.

3. Agricultural and industrial development: Farmers can sell their produce in distant markets, and industries can obtain raw materials from far-off places, boosting both agricultural and industrial growth.

4. Employment generation: The transport and communication sector itself provides employment to millions of people.

5. National unity and security: Roads and railways connect remote border areas with the mainland, strengthening national integration and enabling quick movement of defence forces.

6. Communication networks (telephone, internet, postal services) facilitate the exchange of information, enabling trade, governance, and social interaction.

Thus, just as blood vessels are lifelines of the human body, transportation and communication networks are the lifelines of a nation and its economy.
3(ii)Write a note on the changing nature of the international trade in the last fifteen years.Show solution
Given: Changes in international trade over the last fifteen years.

Answer:

International trade refers to the exchange of goods and services between countries. The nature of India's international trade has changed significantly in recent years:

1. Shift from raw materials to manufactured goods: Earlier, India mainly exported raw materials and agricultural products. Now, India exports a large variety of manufactured goods, engineering products, software, and services.

2. Growth of service sector exports: India has emerged as a major exporter of IT services, business process outsourcing (BPO), and software. This has transformed the composition of exports.

3. Diversification of trading partners: India's trade is no longer limited to a few countries. It now trades with a large number of countries across Asia, Europe, America, and Africa.

4. Increase in volume: The total volume of India's international trade has grown enormously due to liberalisation and globalisation policies adopted since 1991.

5. Rise of sea ports and airports: Modern ports like Jawaharlal Nehru Port (Mumbai) and airports have been developed to handle the increased volume of international trade.

6. Trade balance: India imports more than it exports in goods (trade deficit), but earns significantly through service exports and remittances.

Thus, international trade has become more diversified, technology-driven, and larger in volume, playing a crucial role in India's economic growth.
