Case Based Questions

Read the case/source given and answer the following questions.

The distribution pattern of the Railway network in the country has been largely influenced by Physiographic, economic and administrative factors. The Northern plains with their vast level land, high population density and rich agricultural resources provided the most favourable condition for their growth. However, a large number of rivers requiring construction of bridges across their wide beds posed some obstacles. In the hilly terrains of the peninsular region, railway tracts are laid through low hills, gaps or tunnels. The Himalayan mountainous regions too are unfavourable for the construction of railway lines due to high relief, sparse population and lack of economic opportunities. Likewise, it was difficult to lay railway lines on the sandy plain of Western Rajasthan, swamps of Gujarat, forested tracks of Madhya Pradesh, Chhattisgarh, Odisha and Jharkhand. The contiguous stretch of Sahyadri could be crossed only through gaps or passes (Ghats). In recent times, the development of the Konkan railway along the West coast has facilitated the movement of passengers and goods in this most important economic region of India.

It has also faced a number of problem such as sinking of track in some stretches and landslides.
(i) Which factors are largely responsible to influence the railway network in India? Write any one merit of railways.
(ii) Why is it difficult to construct railway lines in the Peninsular region and Himalayan region?
(iii) Although, the railways have become more important in our national economy still this transport is facing a number of problems.Why? State any two reasons.
Answer : Factors which are largely responsible to influence the railway network in India are physiographic, economic and administrative factors. An advantage or merit of railways is that they make it possible to conduct many activities like business, sightseeing, pilgrimage along with transportation of goods over longer distances.
(ii) It is difficult to construct railway lines in the Peninsular region and Himalayan region because ! The Peninsular region and the Himalayan region are hilly and mountainous regions. Peninsular region has undulating topography where railway tracts are laid through low hills, gaps or tunnels. ! On the other hand the Himalayas have high relief, sparse population and lack of economic opportunities.
(iii) It is true that railways have become more important in our national economy but still this transport is facing a number of problems which are ! Many passengers travel by trains without tickets. This incurs heavy loss of rail budget. ! People stop the trains, pull the chain unnecessarily and this causes heavy damage to the railway. 2. Read the cases/sources given and answer the following questions. Source A Golden Quadrilateral Super Highways The government has launched a major road development project linking Delhi–Kolkata– Chennai–Mumbai and Delhi by six-lane Super Highways.

Question: Read the source given below and answer the question that follows: Consequently, manufacturing activity tends to locate at the most appropriate place where all the factors of industrial location are either available or can be arranged at lower cost. After an industrial activity starts, urbanisation follows. “Industrialisation and urbanisation go hand in hand”. Explain and validate the statement.
Answer: As soon as any industrial activity starts in a town, urbanisation follows. Industry provides employment to skilled and semiskilled labourers in large numbers. Population migrates from rural hinterlands to seek jobs in these industries. Once mass migration occurs, the town develops its housing and transportation facilities to accommodate these people. Schools, colleges, markets, hospitals and other infrastructural facilities follow once the living standard of the inhabitants is capable enough to support them. Slowly, an uninhabited town becomes a fully-functional city with all kinds of facilities available for its citizens. Thus Industrialisation and Urbanisation go hand in hand.

Question: Explain the ways through which the industrial pollution of fresh water can be reduced. 
Answer: Ways to reduce industrial water pollution are –
(1) Minimising water usage for processing and other steps in various equipments by reusing the same water again and again and recycling it in two or more successive stages.
(2) Harvesting rainwater to meet household water requirements and also to help rejuvenate ground water can also reduce water pollution.
(3) Treatment of hot water and affluents before releasing them in rivers and ponds multiple times to avoid release of toxins like arsenic, lead and mercury.
(4) Segregation of wastes into various categories and appropriate treatment thereafter can also help save plastic from being dumped into water bodies. Plastics choke aquatic animals, thus killing them.
