Q.2. What is the significance (importance) of : (a) National Highways and (b) Border Roads?

Ans. (a) The National Highways are the primary road systems of our country. They link extreme parts of the country and provide connectivity between the different states of India. They have been planned to meet the requirement of fast movement of traffic in the country. A number of major National Highways run in north-south and east-west directions. They connect most of the important towns and cities of the country. The National Highways are laid and maintained by the Central Public Works Department (CPWD).

(b) The Border Roads are vital road links along the frontiers of our country. These roads are of strategic importance. They have improved accessibility in areas of difficult terrain mainly in the northern and notheastern border areas. They have played a major role in the economic development of these areas. The Border Roads Organisation, a government of India undertaking, was established in 1960 for the purpose of building the border roads. The organisation is in charge of construction and maintenance of these road.

Q.3. Mention four merits of road transportation with reference to India.

Ans. Roadways are the most important means of transportation in India. India has one of the largest networks of roadways in the world, aggregating to about 2.3 million km at present. Road transport has preceded railways and still have an edge over it in view of the ease with which it can be built and maintained. Other means of transport like pipelines have limited application and waterways are localised in rivers and water bodies while airways are costly and out of reach of common people.

Road transport is more useful than railways on account of its following merits :

(a) Construction and maintainence cost of roads is much lower than that of railways.

(b) Roads can traverse comparatively more dissected and undulating topography. They can negotiate higher gradients of slopes and can traverse mountainous regions such as the Himalayas. They can reach remote villages and hilly regions where railway tracks cannot be constructed.

(c) Roads provided door to door service, thus the cost of loading and unloading is much lower.

(d) Road transport is also used as a feeder to other modes of transport, for example, they provide a link between railway stations, airports and ports. They link the village, towns and cities to the railway stations. They provide linkage between ports and markets and trading centres.

Q.4. Where and why is rail transport the most convenient means of transportation?

Ans. Railways can transport larger number of goods and passengers over long distances at economical cost. Hence, Railways are the most convenient means of transport in the vast Northern Plains of India. The flat terrain, dense population, rich agricultural resources and greater industrial activity have favoured the development of railways in this region. The Northern Plains, therefore, have the densest road networks. Railways have accelerated the development of industry and agriculture in this region by providing quick availability of raw materials and distributing the finished products to the market.

 

Q.5. Why are the means of transportation and communication called the lifeline of a nation

and its economy?

Ans. Transport system is the means for movement of goods and services from their supply locations to demand locations. The means of transport provide an important link between the producers and consumers of goods. The transport routes or channels are, thus, the basic arteries of our economy. Therefore, efficient means of transport are prerequisites of fast development. They help in development of agriculture and industry by providing raw materials and distributing finished product. A well-knit transport and communication system brings people of different regions within the country and the world closer to one another. This promotes interdependencies between them.

With the development in science and technology, the area of influence of trade and transport has expanded far and wide. Different countries, geographically far from each other, are now engaged in trade relations. A product made in the USA is now available in India. Efficient, and fast-moving transport and communication system has helped to convert the world into a large, closely knit global village. India is part of this network and is well connected with the rest of the world. Its flourishing international trade has added vitality to its economy and enriched the lives of the people by raising their living standards.

A dense and efficient network of transport and communication is a prerequisite of local, national and global trade of today. Thus, modern means of transport and communication serve as lifelines of our nation and its modern enonomy.

Q.6. What is meant by trade? What is the difference between international and local trade?

Ans. Exchange of goods, commodities or services between people, states or countries is termed as trade. Trade means the exchange of products between regions of surplus and regions of deficiency.

The exchange of commodities between two or more countries is termed as international trade.

It may take place through sea, air or land routes.

While local trade is carried on within cities, towns or villages. Exchange of the items take place in local markets where items of local needs are catered to. Local trade mainly takes place through roads, railway or inland waterways.

Export and import are the components of international trade. When goods are traded out from a country to other countries, it is termed as export. When goods are traded and brought into a country from other countries, it is termed as import.

Export means earning of foreign exchange by the country while imports involve use of foreign exchange.

The difference between export and import of a country is termed as its balance of trade. When the value of exports exceeds the value of imports, it is called favourable balance of trade. If the value of imports exceeds the value of exports, it is termed as unfavourable balance of trade.

Q.7. Write a note on the changing nature of the international trade in the last fifteen years.

Ans. India has trade relations with all the major trading blocks and all geographical regions of the world. Among the commodities of export, whose share has been increasing over the last few years till 2004-05, are agriculture and allied products (2.53%), ores and minerals (9.12%), gems and jewellery (26.75%) and chemical and allied products (24.45%), engineering goods (35.63%) and petroleum products (86.12%).

The commodities imported by India included petroleum and petroleum products (41.87%), pearls and precious stones (29.26%), inorganic chemicals (29.39%), coal, coke and briquettes (94.17%) machinery (12.56%). Bulk imports as a group registered a growth accounting for 39.09% of total imports.

This group includes fertilisers (67.01%), cereals (25.53%), edible oils (7.94%) and newsprint (5.51%)

International trade has undergone a sea of change in the last fifteen years. Exchange of commodities and goods have been superseded by the exchange of information and knowledge. India has emerged as a software giant at international level and it is earning large foreign exchange through the export of Information Technology because of its fast growing Business Process Outsourcing (BPO) sector.

Class IX - Population

NCERT TEXTBOOK QUESTIONS

Questions Within The Lesson

Q.1. Find out what could be the reasons of uneven distribution of population in India.

(Page 54)

Ans. Rugged terrain and unfavourable climatic conditions are primarily responsible for sparse population in some areas. Hilly, dissected and rocky nature of the terrain, moderate to low rainfall, shallow and less fertile soils influence population in hilly areas. Flat plains with fertile soils and abundant rainfall have led a large number of people to settle in the densely populated Northern Plains.

Q.2. Table 6.1 reveals that despite the decline growth rates, the numbers of people being added every decade is steadily increasing. Why? (Page 56)

Ans. Increased facilities provided to live a comfortable life and better medical facilities that have brought down the death rate is the cause for increase in people being added every decade despite the decline in growth rate.

Q.3. Find out what could be the reasons for such (sex ratio) variations. (Page 58)

Ans. The reasons for sex ratio variations in the states of India is the social makeup of India. The people here have remained in favour of male child leading to female foeticide and dowry problems which makes people think of female children as a burden. In states like Kerala there are well educated people who also follow matriarchal society rules and sex ratio in Kerala is 1058 females per 1000 males. In Haryana female child is looked down upon and most female foeticide cases occur here. Thus it has sex ratio of 861 females per 1000 males.

Questions in the Exercise

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

(i) Migrations change the number, distribution and composition of the population in:

(a) the area of departure (b) both the area of departure and arrival

(c) the area of arrival (d) none of the above

Ans. Both the area of departure and arrival

(ii) A large proportion of children in a population is a result of

(a) high birth rates (b) high life expectancies

(c) high death rates (d) more married couples

Ans. High birth rates

(iii) The magnitude of population growth refers to :

(a) the total population of an area

(b) the number of persons added each year

(c) the rate at which the population increases

(d) the number of females per thousand males

Ans. The total population of an area

(iv) According to the Census 2001, a literate person is one who

(a) can read and write his/her name

(b) can read and write any language

(c) is 7 year old and can read and write any language with understanding

(d) knows 3 Rs (reading, writing, arithmetic)

Ans. Is seven year old and can read and write any language with understanding.

Q.2. Answer the following questions briefly.

(i) Why is the rate of population growth in India declining since 1981?

Ans. The rate of population growth has been declining as a result of greater use of birth control measures.

(ii) Discuss the major components of population growth.

Ans. The major components of population growth are Birth Rate, Death Rate and Migration. The difference between birth rate and death rate accounts for natural increase in population. Adoption of family planning measures leads to decline in birth rate. Better availability of medical facilities leads to decrease in death rate.

Internal migration only changes the pattern of population over different parts of the country. International migration affects both the magnitude and the quality of population.

(iii) Define age structure, death rate and birth rate.

Ans. Birth rate is the number of live births per thousand persons in a year. Death rate is the number of deaths per thousand persons in a year. Age structure refers to the number of people in different age groups.   The commonly adopted age groups are Children (0-14 years), Adults (15-59 years) and Aged (60 years and above)

(iv) How is migration a determinant of population change?

Ans. Internal migration determines population change across regions and territories within the country. In India there has been a significant migration from the rural areas to the cities. Apart from magnitude, migration also brings about change in terms of sex ratio and age composition. The migration from rural areas comprises only men. As such, the sex ratio in village registers a decline and so does the age composition. The number of able-bodied men in villages is reduced as a result of the rural-urban migration.

Q.3. Distinguish between population growth and population change.

Ans. Population growth is different from population change. Population growth is determined by the birth and death rates. Population change, on the other hand, is determined by the birth and death rates and also by migration.

Q.4. What is the relation between occupational structure and development?

Ans. Development is related to occupational structure of the population. Countries are less developed where a higher percentage of population is engaged in primary occupations like agriculture, animal husbandry, forestry and fishing.

As development takes place more people move into secondary occupations like manufacturing.In highly developed societies, there are a high percentage of people involved in tertiary occupations like banking, commerce, transport and administration.

Q.5. What are the advantages of having a healthy population?

Ans. Health is an important component of population composition, which affects the process of develpment. A healthy population ensures higher productive efficiency. Absenteeism is low where the workers are healthy.

Q.6. What are the significant features of the National Population Policy 2000?

Ans. (i) The National Population Policy 2000 aims at reducing infant mortal rate to below 30 per thousand live births. (ii) The policy framework provides for imparting free and compulsory school education up to 14 years of age. (iii) Some other areas of attention are promoting delayed marriages for girls and achieving universal immunisation of children against all vaccine preventable diseases. Family planning programme is to be promoted on a voluntary basis.
