CBSE Class 12 Geography NCERT Solutions: Transport and Communication

(i) The correct option is (c) 16. The Indian Railways network is currently organized into 16 zones to manage its vast operations effectively across the country.

(ii) The correct option is (b) The Ganga, Haldia-Allahabad. National Waterway No. 1 is a significant inland waterway that runs along the River Ganga, connecting Haldia in West Bengal to Allahabad in Uttar Pradesh.

(iii) The correct option is (d) 1923. Radio broadcasting in India commenced in 1923, marking the beginning of this important medium for information and entertainment.

(i) Transportation conveys the fundamental human activity of mobility, which is essential for trade, economic activities, and accessing daily necessities. It facilitates the movement of goods from production sites to markets, making them available to consumers. The three major modes of transportation are Road, Rail, and Air.

(ii) Advantages of Pipeline Transportation: Pipelines offer large capacity for transporting liquids and gases, are a safer means of transport with lower energy use, and can be more environmentally friendly. They also have a shorter construction time frame compared to some other modes.

Disadvantages of Pipeline Transportation: Pipelines are primarily limited to transporting liquids and gases. Issues like illegal pilferage, wastage due to leaks, and the significant task of patrolling and maintenance are major concerns. Leakages, especially in chemical or petroleum pipelines, can also lead to accidents.

(iii) 'Communication' refers to the process of transferring information, ideas, or messages from one entity (person, group, or place) to another. It involves a sender, a message, a channel, and a receiver.

(iv) Air India and Indian (now merged into Air India) have played a vital role in India's air transport sector. Post-independence, Air India (formerly Tata Airways) expanded its international routes, while Indian Airlines focused on domestic services. Together, they have facilitated significant passenger and cargo movement, contributing to national and international connectivity.

(i) The chief means of transportation in India are Road, Rail, and Air transport, supplemented by Water transport. The development of these modes is influenced by several factors:

Historical Factors: These include the evolution of settlement patterns, historical trade routes, and the development of infrastructure over time.

Technological Factors: Advances in technology significantly impact the efficiency, speed, and capacity of transport modes, such as the development of faster trains or larger aircraft.

Physical Factors: The country's physiography, including mountains, rivers, plains, and climate, plays a crucial role in determining the feasibility and cost of establishing transport routes.

Economic Factors: The economic viability, cost of construction and operation, demand for transport services, and pricing strategies are critical economic considerations affecting development.

(ii) The development of railways in India began during the British colonial era, with the first train running in 1853. Indian Railways (IR) has since grown into the fourth-largest rail network globally and one of the busiest. Its importance lies in its capacity to transport vast numbers of passengers and large quantities of goods efficiently and relatively safely over long distances. Railways are crucial for connecting remote areas, supporting industrial growth, facilitating inter-state trade, and enabling mass mobility, making them a backbone of India's transportation system.

(iii) Roads play a pivotal role in the economic development of India. They provide essential connectivity, especially for the 'last mile' delivery, linking production centers to markets and consumers. Road transport is faster and more cost-effective for short to medium distances compared to other modes, reducing transit times and costs for goods. This improved accessibility supports agricultural and industrial development, promotes trade, facilitates tourism, and creates employment opportunities, thereby contributing significantly to the overall economic growth of the nation.
