In many respects, radio, film, television, newspapers, aeroplanes, rivers, railroads, and the internet have all aided in the socioeconomic development of the country.

International trade is defined as trade between nations. Over the past fifteen years, there has been a significant shift in international trade.

For example, India has become a global software powerhouse and is generating significant foreign exchange profits from the export of information technology. In addition to external variables like taxes and levies on the movement of commodities, international trade is also influenced by the relationships between the nations. The emergence of several trade blocs over the past fifteen years has altered the old methods of conducting international trade.

Why Roadways is an Important Network

India has one of the largest road networks in the world. Road transport preceded rail transport and still has an edge over it because of the ease of construction and ability to negotiate higher gradients of slopes like the Himalayas. According to the lifelines of national economy class 10 curriculum, roads are classified into six classes:

1. Golden Quadrilateral Super Highways: A major project linking Delhi-Kolkata-Chennai-Mumbai by six-lane super highways.

2. National Highways: Primary road systems maintained by the CPWD. The historical Sher Shah Suri Marg is National Highway No. 1.

3. State Highways: Roads linking a state capital with different district headquarters.

4. District Roads: Connect district headquarters with other places of the district.

5. Other Roads: Rural roads which received a boost under the Pradhan Mantri Grameen Sadak Yojana.

6. Border Roads: Maintained by the Border Roads Organisation (BRO) in the bordering areas of the country.

Why Railways is the Backbone of Domestic Transport

Railways are the principal mode of transportation for freight and passengers in India. They make it possible to conduct multifarious activities like business, sightseeing, and pilgrimage over long distances. As noted in the lifelines of national economy class 10 notes, the Indian Railway network is one of the largest in the world.

However, the distribution pattern of the railway network is influenced by physiographic, economic, and administrative factors. For example, the level northern plains with high population density and rich agricultural resources provide the most favorable condition for their growth, whereas the hilly terrains of the peninsular region make construction difficult.

Pipelines and Waterways for Specialized Movement

A relatively new arrival on the transport map of India is the pipeline network. In the past, these were used to transport water to cities and industries. Now, they are used for transporting crude oil, petroleum products, and natural gas.

Waterways are the cheapest means of transport. They are most suitable for carrying heavy and bulky goods. India has several National Waterways, such as:

• NW No. 1: The Ganga river between Allahabad and Haldia.

• NW No. 2: The Brahmaputra river between Sadiya and Dhubri.

Major Sea Ports and Airways

With a long coastline of 7,516.6 km, India is dotted with 12 major and 200 notified non-major ports. According to the lifelines of national economy class 10 questions and answers, these ports handle 95% of India's foreign trade. Key ports include Kandla (the first port developed soon after Independence), Mumbai (the biggest port), and Vishakhapatnam (the deepest landlocked and well-protected port).

Airways represent the fastest, most comfortable, and prestigious mode of transport. It can cover very difficult terrains like high mountains, dreary deserts, and dense forests with great ease. In India, air transport was nationalized in 1953. Pawanhans Helicopters Ltd. provides services to oil and natural gas sectors and inaccessible areas.

Transport as "Economic lifeline"

A unique way to view the concepts in Chapter 7 is to see the transport network as "Economic Arteries." Just as arteries carry oxygenated blood to every cell in the human body to keep it alive and functioning, the transport system carries the "oxygen" of resources, food, and finished products to every corner of the nation. Without these lifelines, the body of the national economy would become stagnant. This framing helps students realize that infrastructure is not just about concrete and steel; it is about the living, breathing circulation of a country's wealth and survival.
