2. Answer the following questions in about 30 words.

(i) Very hot and dry and very cold and wet regions of India have low density of population. In this light, explain the role of climate on the distribution of population.

Answer

Climate plays a very important role in influencing population. The two elements of climate, rainfall and temperature play the most important role in determining the population of an area.
When a place has extremes of climate, the density of population is low such as too cold climate of Himalayas, and the too hot and dry climate of the Thar Desert. When a place has moderate climate, it attracts people and has high density of population.
Rainfall supplies water for agriculture which is the main occupation of Indian people. The amount of rainfall decreases as we move from the Ganga-Brahmaputra Delta in the east towards the Thar Desert in the west.

(ii) Which states have large rural population in India? Give one reason for such large rural population.

Answer

The states like Bihar and Sikkim have very high percentage of rural population. The reason is both states Bihar and Sikkim are highly dependent on agriculture for their livelihood.

(iii) Why do some states of India have higher rates of work participation than others?

Answer

In India, the work participation rate are higher in the areas of lower levels of economic development since number of manual workers are needed to perform the subsistence or near subsistence economic activities

(iv) ‘The agricultural sector has the largest share of Indian workers.’ – Explain.

Answer

About 54.6 per cent of total working population are cultivators and agricultural labourers, whereas only 3.8% of workers are engaged in household industries and 41.6 % are other workers including nonhousehold industries, trade, commerce, construction and repair and other services.

3. Answer the following questions in about 150 words.

(i) Discuss the spatial pattern of density of population in India.

Answer

Density of population, is expressed as number of persons per unit area. It helps in getting a better understanding of the spatial distribution of population in relation to land. The density of population in India is 382 persons per sq km.

• The spatial variation of population densities in the country ranges from as low as 17 persons per sq km in Arunachal Pradesh to 11,320 persons in the National Capital Territory of Delhi.

• Among the northern Indian States, Bihar (1106), West Bengal (1028) and and Uttar Pradesh (829) have higher densities, while Kerala (860) and Tamil Nadu (555) have higher densities among the peninsular Indian states. 

• States like Assam, Gujarat, Andhra Pradesh, Haryana, Jharkhand, Odisha have moderate densities. 

• The hill states of the Himalayan region and North eastern states of India (excluding Assam) have relatively low densities while the Union Territories (excluding Andaman and Nicobar islands) have very high densities of population.

(ii) Give an account of the occupational structure of India’s population.

Answer

The occupational structure of a country refers to the division of its work force engaged in different economic activities.

• India have  a large proportion of primary sector workers compared to secondary and tertiary sectors.

• About 54.6 percent of total working population are cultivators and agricultural labourers, whereas only 3.8% of workers are engaged in household industries and 41.6 % are other workers including non-household industries, trade, commerce, construction and repair and other services.

• As far as the occupation of country’s male and female population is concerned, male workers outnumber female workers in all the three sectors.

• The number of female workers is relatively high in primary sector, though in recent years there has been some improvement in work participation of women in secondary and tertiary sectors.

• The proportion of workers in agricultural sector in India has shown a decline over the last few decades (58.2% in 2001 to 54.6% in 2011).

• Consequently, the participation rate in secondary and tertiary sector has registered an increase. This indicates a shift of dependence of workers from farm based occupations to non-farm based ones, indicating a sectoral shift in the economy of the country.

Short Answer Type Questions

Question 1.
What do you mean by ‘Dualism in Geography?
Answer:
The teaching and learning of Geography has been a matter of debate amongst geographers. Some examples are:

  • Whether geographical phenomena be theoretically interpreted or through historic-institutional approach;
  • Whether subject matter be organised and approach to study and teach geography should be regional or systematic;
  • Whether geography as a discipline should be a law making/theorising or descriptive?

Question 2.
State some examples of metaphors used to describe the physical and human phenomena.
Answer:
Some examples of metaphors used to describe the physical and human phenomena are as follows:

  • “Face’ of the earth.
  • ‘Eye’ of the storm.
  • Regions, villages, towns have been described as ‘organisms’.
  • Networks of roads, railways and water ways are described as “arteries of circulation”.
  • “Mouth’ of the river.
  • ‘Snout’ (nose) of the glacier.
  • “Neck’ of the isthmus.
  • “Profile’ of the soil.

Question 3.
When and how did Human Geography begin? Explain.
Answer:
Human Geography may be said to have originated since man has started interacting with his environment. It has its roots deep in history. Therefore, the concerns of human geography have a long temporal continuum though approaches to articulate them have changed over time. This dynamism and changes in articulation are indicator of vibrant nature of the discipline.

In the beginning, the interaction between various societies was negligible. Therefore knowledge about each other was also limited. Travelers and explorers used to gather information before a journey and navigational skills were underdeveloped. In late 15th century, Europe witnessed attempts of explorations and the myths and mysteries about countries and people started to open up.

In the colonial period, these attempts increased with an objective of getting access to resources and to obtain inventorised information. Through all this we get to know the sequential information about the development of human geography and to understand that the development of this discipline has been a steady process.

Question 4.
Make a list of elements that human beings have created through their activities on the stage provided by physical environment.
Answer:
Man creates many elements through his activities on the stage provided by physical environment with the help of technology. Houses, villages, cities, farms, ports, items of our daily use and all others So elements of material culture have been created by man using the resources provided by physical environment.

Question 5.
How do human activities help to create cultural landscape?
Answer:
On the basis of attained knowledge, technology and industries, man has been able to develop cultural landscape. The imprints of human activities are available everywhere.

For example; health resorts on highlands have been used as recreation places, huge urban sprawls, fields, orchards and pastures in plains and rolling hills have added to beauty, ports on the coasts, oceanic routes on the oceanic surface and satellites in the space have enabled man to touch the heights of the sky. This was coined the term “Possibilism.’.

Question 6.
“There is no free run without accidents.” Explain.
Answer:
In this statement, the thought of Possibilism in which man was taken as free, uncontrolled and master of unlimited powers has been criticized because as a consequence of free run of developed economies many problems are being faced today like green house effect, ozone layer depletion, global warming, receding glaciers, degrading lands, problem of pollution and incurable diseases.

Long Answer Type Question

Question 1.
Describe the fields and sub-fields of Geography and its inter-relationship with other fields.
Answer:
Nature of Human Geography is inter-disciplinary. In order to understand and describe the human elements found on the earth, human geography has established strong bond with other social sciences and their helping subjects. With the expansion of knowledge, new subjects keep on developing. These are studied with humanistic approach but because they are not free from geographical and environmental effects, they become subject matter of human geography. Fields under Human Geography include: Social Geography, Urban Geography, Political Geography, Population Geography, Settlement Geography and Economic Geography.

Sub-fields of Social Geography are: Behavioral Geography, Geography of Social Well-being, Geography of Leisure, Cultural Geography, Gender Geography, Historical Geography and Medical Geography.

Sub-fields of Political Geography are Electoral Geography and Military Geography. Sub-fields of Economic Geography are: Geography of Resources, Geography of Agriculture, Geography of Tourism, Geography of Industries, Geography of Marketing and Geography of International Trade.

Other than this, Sociology, Psychology, Welfare Economics, Demographic Studies, History, Epidemiology, Anthropology, Urban Studies and Planning, Political Science, Psephology, Military Science, Demography, Urban or Rural Planning, Agricultural Sciences, Industrial Economics, Business Studies, Commerce, Tourism 6s Travel Management and International Trade are such disciplines which study human activities and behavior. As the scope of these disciplines is expanding, it is also leading to increase in the scope of Human Geography.

Question 2.
How did man develop and expand proper technology?
Answer:
Human beings were able to develop proper technology using his knowledge and intelligence. It has taken man a long time to reach at the present level of technology. In primitive age when the level of technology was very low man was bound to follow the dictates of nature. In those times man was a slave of nature, scared of its powerful force and used to worship nature to make it happy. In these conditions the state of cultural development was also primitive.

However, the process was gradual but man developed technology and it is also to be noted that man has been able to utilize this technology only after understanding the various laws of nature. For example; understanding of laws of friction gave birth to many inventions. Similarly after understanding secrets of DNA and laws of genetics, man has overcome many diseases and aeroplanes could be invented only after understanding the laws of aerodynamics. Today the level of technology is touching the heights of sky through which man seems to get free from the natural forces. Earthquake, cyclones, landslides, volcanoes and other natural disasters keep reminding man that he is still a slave to nature.

It implies that man can’t be completely free from natural forces but with the development of technology man has become free from nature and this freedom can be expanded further. Man needs to follow Stop and Go approach. It means possibilities can be created within the limits which do not damage the environment and there is no free run without accidents.
