Q1 Why is people considered as resource?
Answer
People are considered a resource because
with their demands and capabilities they can create new resources. Nature's
bounty becomes important only when people find it and make it useful for them.
Hence, human resource is also considered an important and potential resource
for the society.
(ii) What are the causes for the uneven distribution of population
in the world?
Answer
The distribution of population in the world is uneven - some areas are
very crowded while some are sparsely populated. There are various reasons
behind uneven distribution:
Geographical factors: Favourable topography,
availability of mineral and fresh water resources, favorable climate and soil
fertility are some of the reasons affecting population distribution e.g., Indo
Gangetic Plains, Diamond Mines of South
Africa etc are densely populated.
Social and Cultural factors: Areas of better housing,
education and health facilities are more populated. Places of religious and
cultural significance also attract people e.g., Varanasi, Jerusalem etc.
Economic factors: Places having more industries,
transportation and communication facilities provide better employment
opportunities. People are attracted to these places because of the above reasons
e.g., Mumbai, Osaka etc.
Question 3: The
world population has grown very rapidly. Why?
Answer: With advancements in science
and technology, food production has increased. Development in healthcare
facilities has helped in reducing death rate. Due to this, the world population
has grown very rapidly.
(iv)
Discuss the role
of any two factors influencing population change.
The birth rate and the death rate are two
factors that influence population change. The birth rate is the number of live
births per 1000 people while the death rate is the number of deaths per 1000
people. These are the natural causes of population change. When the birth rate
is higher than the death rate, population increases. When the death rate is
more than the birth rate, population decreases. When the two rates are equal,
the population remains constant. Thus, the birth and death rates affect the
balance of population.
(v) What is meant by population composition?
Population composition refers to the
structure of the population. Population composition helps to know the number of
males or female, their age-groups, literacy, their occupation, their income
level and health conditions etc.
(vi)
What are
population pyramids? How do they help in understanding about the population of
a country?
Answer
The graphical
illustration that is used for studying the population composition of a country
is called population pyramid. It shows the present number of males and females
in a country along with their age groups. The age groups of population tell us
the number of dependent and the number of economically active individual
present in the population.
