D. Answer the following questions in brief.

  1. What is meant by the growth rate of population?

Answer – The growth rate of population refers to the change in the number of people in a population over a specific period of time. It is usually expressed as a percentage and is influenced by birth rate, death rate, and migration.

  1. What are the three important attributes of population composition?

Answer – The three important attributes of population composition are:

Sex ratio

Age structure

Literacy level

  1. What makes the human beings the most valuable resource?

  1. Which regions of the world have high concentration of population and why?

Answer – Regions like the Ganga-Brahmaputra plains, Eastern China, Europe, and Southeast Asia have high population concentration due to fertile soil, availability of water, favorable climate, and development of agriculture and industries.

  1. Highlight the characteristics of the sparsely population regions of the world.

Answer – Sparsely populated regions like deserts, mountains, polar areas, and dense forests have extreme climates, poor soil fertility, difficult terrain, and lack of infrastructure, which make human habitation and development difficult.

 

 

 

E. Answer the following questions.

  1. Explain relief and climate as factors affecting the distribution of population.

Answer – Relief refers to the physical features of the land such as mountains, plains, and plateaus. People prefer to live in plains because they are flat, fertile, and suitable for agriculture, transport, and settlements. Mountainous and hilly areas have rugged terrain, making agriculture and transport difficult, resulting in sparse population.

Climate plays a vital role in population distribution. Areas with moderate climate, adequate rainfall, and comfortable temperatures are densely populated (e.g., the Ganga Plains). On the other hand, extreme climates, such as very hot deserts, cold polar regions, or high-rainfall equatorial forests, discourage dense human settlement.

  1. How do minerals and industries affect the distribution of population? Explain.

Answer – Minerals attract people because they provide raw materials for industries and employment opportunities. Areas rich in minerals like coal, iron, and petroleum tend to have dense populations due to the development of mining and associated industries.

Industries provide employment, better infrastructure, and improved standard of living. Industrial areas like Mumbai, Delhi, and Kolkata have high population density because people migrate there in search of jobs and better livelihoods.

  1. What is meant by literacy rate? Why is it considered an important indicator in population composition?

Answer – Literacy rate is the percentage of people above a certain age (usually 7 years and above in India) who can read and write with understanding in any language.

It is considered an important indicator because it reflects the educational level of the population. A higher literacy rate indicates a better skilled and knowledgeable workforce, which contributes more effectively to economic development and nation-building. It also impacts health, productivity, and civic responsibility.

  1. Define sex-ratio. What are the reasons for the declining sex-ratio in India?

Answer – Sex-ratio is the number of females per 1000 males in a population.

In India, the sex-ratio has been declining due to several reasons such as:

Female foeticide and infanticide

Discrimination against girl children in terms of nutrition, education, and healthcare

Cultural preference for sons in many communities

Neglect of women’s health and safety

  1. Which states of India have high density of population and why? Suggest ways and means to check it.

Answer – States like Bihar, West Bengal, Uttar Pradesh, and Kerala have high population density due to:

Fertile plains

Availability of water

Favourable climate

Development of agriculture and trade

Urbanisation and industrialisation (in some areas)

Ways to check high population density include:

Promoting family planning and awareness programs

Improving education, especially of women

Creating job opportunities in rural areas to reduce migration

Developing infrastructure in less populated areas to balance distribution

 

 

Value Based Question

The main goal of ‘Ski 11 India Programme’ is to create opportunities, space and scope for the development of the talents of Indian youth. The emphasis is to equip the youth in such a way so that they get employment and also improve entrepreneurship. The idea is to raise confidence, improve productivity and give direction through development of skills right at the school level.

India is one of the few countries all across the world where working age population will be very high due to high growth rate of population in the coming years. It is time to open up avenues for job creation and social security schemes in the Indian economy.

(1)  Give any three arguments to support the idea of introducing programmes for the development of skills, right at the school level.

Answer – Early Exposure and Career Readiness – Skill development at the school level helps students identify their strengths and interests early, making them better prepared for future careers and reducing dependency on higher education alone for employment.

Boost to Employment and Entrepreneurship – Equipping students with practical skills (like IT, communication, carpentry, coding, etc.) opens up multiple employment and self-employment opportunities, especially in rural and semi-urban areas.

Increased Confidence and Productivity – Skill-based education enhances confidence, responsibility, and productivity among youth, making them more self-reliant and reducing unemployment pressure on the economy.

(2) What more new ways can be linked to a better human resource development?

High Order Thinking Skill (HOTS) Questions and Answers

  1. Question: Analyze why India’s population density varies significantly across states, using both physical and economic factors.
    Answer: India’s population density varies due to a combination of physical and economic factors. Physically, states like Bihar and West Bengal have high densities (1102 and 1029 persons per sq. km) due to fertile soils in river valleys, favorable monsoon climates, and flat terrain conducive to agriculture and settlement. Conversely, states like Arunachal Pradesh (17 persons per sq. km) have low density due to rugged terrain, dense forests, and harsh climates. Economically, industrialized states like Maharashtra attract populations due to employment opportunities in urban centers like Mumbai. In contrast, regions with poor infrastructure, like parts of Rajasthan, have lower densities due to limited economic prospects. These factors collectively shape uneven population distribution.
  2. Question: Evaluate the impact of a declining sex-ratio on India’s socio-economic development.
    Answer: A declining sex-ratio, such as India’s 943 females per 1000 males in 2011, has significant socio-economic consequences. Socially, it perpetuates gender inequality, reinforcing patriarchal norms and increasing crimes against women due to skewed demographics. Economically, it reduces the female workforce, limiting contributions to GDP and innovation, as women’s education and empowerment are critical for development. Additionally, a lower sex-ratio strains marriage markets, potentially increasing social unrest. Addressing this through policies promoting gender equality and preventing female foeticide is essential for balanced development.
  3. Question: Predict the long-term consequences of India’s rapid population growth if current trends continue, and suggest a mitigation strategy.
    Answer: If India’s population growth continues at its current rate, it could double in 36 years, leading to overexploitation of resources, increased poverty, and strained infrastructure (e.g., healthcare, education, and transport). Urban overcrowding and environmental degradation would intensify, exacerbating climate challenges. A mitigation strategy could involve promoting family planning through education and access to contraceptives, coupled with incentives for smaller families, to stabilize population growth while enhancing human capital development.
  4. Question: Compare the population pyramids of India and Japan and explain how they reflect their respective demographic challenges.
    Answer: India’s population pyramid is broad at the base due to high birth rates, indicating a young, growing population with challenges like providing education and jobs for a large youth cohort. Japan’s pyramid is narrow at the base due to low birth rates and wide at the top, reflecting an aging population with challenges like a shrinking workforce and increased healthcare costs for the elderly. India must invest in youth development, while Japan needs policies to support its aging population and encourage higher birth rates.

Long Questions and Answers

  1. Question: Explain the factors affecting the distribution of population, distinguishing between physical and economic factors, with examples.
    Answer: The distribution of population is influenced by physical and economic factors that collectively determine where people settle.

Physical Factors:

  • Relief: Flat plains, like the Ganges valley in India, support agriculture and transportation, attracting dense populations, while rugged terrains like the Himalayas are sparsely populated.
  • Climate: Moderate climates, such as India’s monsoon regions, encourage settlement, whereas extreme climates like the Sahara desert deter habitation.
  • Soil and Water: Fertile soils and adequate water, as in the Nile valley, support agriculture, leading to high population density, unlike deserts with scarce water.
  • Vegetation: Dense equatorial forests are less accessible, reducing population, while monsoon forests are more habitable.

Economic Factors:

  • Minerals: Areas rich in coal, iron, or petroleum, like Jharkhand or Saudi Arabia, attract industrial settlements and migrant workers.
  • Industries: Industrial hubs like Western Europe or Maharashtra draw populations due
