Class 8 Chapter 5 Human Resources
Q.1Why are people considered a resource?
Ans : 1.People are considered resources because they can produce new resources with their
demands and capabilities.
2.Nature's abundance is only valuable when people discover it and put it to good use. 3.They
gain abilities and aptitudes through education, good health, and motivation, allowing them to
become more proficient in overcoming obstacles and hurdles and carrying out more duties
effectively.
4.As a result, human resources are regarded as valuable and potentially valuable resources for
society.
Q.2 What is birth rate?
Ans : Births are usually measured using the birth rate i.e. the number of live births per thousand
people. When birth rate is more than death rate, population increases.
Q.3 What is Death rate?
Ans: Death rate is influencing factor of population change.Death share usually measured using
the death rate that is a number of deaths per thousand people.
Q4. The World Population Has Grown Very Rapidly. Why?
Ans: 1.The death rate has decreased as a result of increased food supply and improved medical
services, resulting in the rapid growth of the global population.
2.Furthermore, unlike the death rate, the birth rate has stayed relatively constant.
Thus the world population has grown very rapidly.
Q5. What is Meant by Population Composition?
Ans: 1.The basic structure of the population is referred to as population composition. 2.The
number of males and females, their age groups, ethnicity, tribe, language, religion, literacy,
occupation, income level, and health problems, among other things, are all determined by the
population composition.
Q6. What are Population Pyramids? How Do They Help in Understanding the Population of a
Country?
Ans: 1.Population pyramids are a type of graphical representation used to analyze a country's
population composition.
2.It depicts the current male and female population of a country, as well as their age categories.
3.The number of dependents and economically active individuals in the population are
determined by the age-group distribution of the population
Q7. Discuss the Role of Any Two Factors Influencing Population Change.
Ans: Population change is the phenomenon of determining whether the population has
increased, decreased, or remained constant. Natural growth and migration are the two most
important elements. The difference between the birth and death rates is the natural growth
rate. The number of live births per 1000 people is the birth rate, while the number of deaths
per 1000 people is the mortality rate. The natural reasons for population change are as follows:
(i)The population rises when the birth rate surpasses the death rate.
(ii)The population declines when the mortality rate exceeds the birth rate.
The population remains constant when the two rates are equal. As a result, birth and death
rates have an impact on population balance. People can travel both within and between
countries. Migration is another factor that influences population change.
Q8. What are the Causes for the Uneven Distribution of Population in the World?
Ans: The world's population distribution is unequal. Some parts of the city are densely
populated, while others are sparsely populated. This unequal distribution can be attributed to a
number of factors:
(i) Geographical Considerations: Topography, mineral and freshwater resources, a favourable
climate, and soil fertility are only a few of the factors that influence population dispersion. Indo
Gangetic Plains, for example.
(ii) Social and Cultural Factors: Population density is higher in areas with better housing,
education, and health care. Consider the city of Pune. People are drawn to places of religious
and cultural significance, such as Varanasi and Jerusalem.
(iii) Economic Factors: Communities with more industry, transportation, and communication
facilities have greater job prospects. People are drawn to these locations for the reasons stated
above, such as Mumbai and Osaka.
Important Points:
Emigration: Movement of people to other countries is called emigration.
Population explosion: Sudden and Rapid increase in population is considered to be a
population explosion
Population distribution: the way in which people are spread across the earth surface is known
as pattern of population distribution.
Migration: the movement of people in and out of an area is called migration
Immigration: movement of people from other countries to our countries is called immigration
Life expectancy: It is the number of years that are average person can expect to live.
