Question 1

Question 2Name the sparsely populated regions of the world.

Accepted Answer

The sparsely populated regions of the world are-The hot deserts like Sahara and Kalahari of Africa, the Arabian desert and Thar desert of Asia, Atacama and Patagonia desert of South America, Great Australian desert and Arizona desert of USA and arid areas of Western Mexico.The cold deserts of Central Asia, the Gobi and Takla Makan desert, a portion of Ladakh in India.Cold polar regions of Arctic in North America, Eurasia and AntarcticaThe dense Equatorial Rainforests of the Amazon and Zaire basin.

Question 2

Question 4How does migration of people affect the total population of a country?

Accepted Answer

People migrate with the intention of settling permanently in the new location, so migration of people leads to decrease of the population of a country i.e., shortage of skilled and competent people in a country.

Question 3

Question 5State any two problems each of overpopulation and under population.

Accepted Answer

Two problems of overpopulation are-Rapid population growth: In most of the under developed countries, population increases rapidly and family planning is not practised on a large scale due to illiteracy and ignorance.Unemployment: In many underdeveloped countries industry is not well-established and there are very few employment opportunities for unskilled workers. Unemployment is therefore high.Two problems of under population are-Uneven distribution of population: Average population densities for underpopulated countries are low, and in many areas there are practically no people at all.Slow growth of industry: The growth of industry is often slow in underpopulated countries because there is a shortage of labour, especially skilled labour

Question 4

Question 7What is meant by population pyramid? Explain with the help of examples.

Accepted Answer

A population pyramid is a graphical representation that shows the distribution of various age groups and gender in a population. Population pyramid for youthful population is shown below:For example, Niger's population pyramid has mostly aged 15 and under and the majority of the population is under 5 years old, which shows how half of the population dies before they reach 30. But in developed countries like USA, Japan, the decrease in birth rate and death rate have kept the base and top at medium level and life expectancy is higher.

Question 5

Question 8Compare and contrast the impact of overpopulation and underpopulation.

Accepted Answer

The following points compare and contrast the impact of overpopulation and underpopulation of a country-Utilisation of Resources — Overpopulation may increase the pressure on the natural resources and the food and fresh water supplies would be inadequate or insufficient which may result in depletion of natural resources while underpopulation may lead to under utilization of resources due to the shortage of labour and less demand.Impact on Environment — Overpopulation would increase the demand for area and this would result in deforestation or loss of natural habitat and increase in pollution levels while underpopulation decreases the pressure on natural resources and the pollution level would also decrease.Impact on Employment — Overpopulation would result in scarcity of jobs while underpopulation would create labour shortage which would have both positive and negative impacts.In conclusion, both overpopulation and underpopulation are not considered good for the economy.

Question 6

Question 9Give one point of difference in the population pyramid of India and Japan.

Accepted Answer

Population pyramid of India — In India, where the death rates are decreasing, the pyramid is broad at the base in the younger age group, as more infants survive to adulthood. Population pyramid of India is shown below:Population pyramid of Japan — In Japan, low birth rates make the pyramid narrow at the base, decreased death rates allow number of people to reach old age. Population pyramid of Japan is shown below:

Question 7

Question 1(a)Distinguish between distribution of population and density of population.

Accepted Answer

Sl.No.Distribution of populationDensity of population1.The number of persons living in a particular area or state is called distribution of populationThe number of persons living on one square kilometre area is called density of population.2.It can be expressed as absolute numbers or in percentage.It is expressed in number of individuals per square kilometre.3.Distribution of population may not be even for a place.Density of population has a fixed value for a given place at a given time.

Question 8

Question 3(a)Mention two impacts of overpopulation.

Accepted Answer

Two impacts of overpopulation are:Overpopulation puts pressure on natural resources such as cultivable land, freshwater and mineral resources, and result in their degradation and depletion.The increase in number of factories to meet the needs of the people results in industrial pollution.

Question 9

Question 4(b)What will happen if the death rate in a year is less than the birth rate?

Accepted Answer

If death rate in a year is less than the birth rate then their will be increase in population which may lead to overpopulation.

Question 5(a)What is a population pyramid?

Accepted Answer

A population pyramid is a graphical representation which shows the distribution of females and males in different age group, at a place. It is also known as age-sex pyramid. It is useful to understand the composition of population of any country.

Question 11

Question 5(b)What does a population pyramid with broad base tell us about the birth and death rates?

Accepted Answer

When the population pyramid is broad at the base and tapering towards the top, it depicts that the death rate as well as the birth rate are high. This type of population pyramid represents the population of underdeveloped countries. The population pyramid shows that although the birth rates are high, still many children die in their infancy, and thus very few people reach old age.

Question 12

Question 5(c)Mention two causes for the imbalance in sex ratio.

Accepted Answer

Two causes for the imbalance in sex ratio are:Migration — As mostly the young male population migrate in search of jobs, this creates an imbalance in sex ratio with high sex ratio in the place of origin and low sex ration in the place of destination.Female Infanticide — Due to poverty, illiteracy, dowry system and desire for male child, Female Infanticide is practiced in some regions which creates an imbalance in sex ratio.

Question 13

Question 3The fertility rate in many developed and developing countries has dropped to about two children per woman.

Accepted Answer

The fertility rate in many developed and developing countries has dropped to about two children per woman due to the factors like literacy, economic development or urbanization making the idea of having big families impractical.
