3. Give reasons – Why?
(i) Environmental aspects must be carefully looked into before building huge dams;
Ans. Dams help in creating hydroelectric power, which solves the energy problems of a region. They also help farmers as the water released from dams is used for irrigation. However, dams have a negative impact on the environment as well. They adversely affect the surrounding ecosystems by destroying the local flora and fauna, by displacing the local community, by changing the natural course of rivers, etc. Therefore, before a dam is built at a site, it should be ascertained whether its benefits justify the damages that it would inevitably cause to the various ecosystems. If they do justify, then steps should be taken to minimise the damages to the flora and fauna, and to relocate the local community. But if they don’t, then environmental conservation should be given the priority over the building of the dam.
(ii) Most industries are concentrated around coal mines.
Ans. Coal is the most abundant fossil fuel. It is widely used as a source of energy. It is also used as a raw material in several industries. Most industries are located around coal mines as being situated close to coal mines proves to be cost effective. Coal can easily be transported from the mines to the industries, and this reduces both time and cost of transportation.
(iii) Petroleum is referred to as “black gold”?
Ans. )The term “black gold” is used with reference to petroleum and its various derivatives. The word ‘black’ refers to the colour of petroleum in its crude form. The word ‘gold’ implies that petroleum and all the various products of petroleum (like diesel, petrol, kerosene, wax, plastics and lubricants) are as valuable to human society as the metal gold.
(iv) Quarrying can become a major environmental concern.
Ans. Quarrying is an extraction process by which minerals lying near the Earth’s surface are dug out. This process can adversely affect the environment in different ways. The digging involves clearing of vegetation. This destroys the top soil, which contains the humus required for plant growth. The quarrying process involves the use of explosives and earth-moving equipment. These cause noise pollution, and may also damage nearby buildings, dams or other such structures. The dust generated during quarrying and the fossil fuels burnt while operating the equipment contribute to air pollution, which in turn affects the health of the miners and the local population.

a. Geographical factors – Favourable topography, availability of mineral and fresh water resources, favourable 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.
b. 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
c. 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.
(iii) The world population has grown very rapidly. Why?
Ans.  The world population has grown very rapidly particularly after 1800s. The reasons are growth in food supplies, improvement in medical facilities, reduced death rate while the birth rate remained the same.
(iv) Discuss the role of any two factors influencing population change.
Ans. 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?
Ans. Population composition refers to the structure of the population of a particular region. The composition of a population helps us to know the number of males and females comprising the population, their age groups, educational and technological skills, occupations, income levels, health conditions, etc
(vi). What are population pyramids? How do they help in understanding about the population of a country?
Ans. The population pyramid or the age sex pyramid is a graphical illustration that is used for studying the population composition of a country. It shows the present number of males and females in a country along with their age groups. The age-group distribution of population tells us the number of dependents and the number of economically active individuals present in the population.
