    Q2. Answer briefly:

    (i) Why is the rate of population growth in India declining since 1981?
    → Because birth rates have been declining gradually due to family planning, awareness, better healthcare, and improved literacy.

    (ii) Discuss the major components of population growth.
    → Birth rate, death rate, and migration. Birth and death determine natural increase, while migration affects distribution and composition.

    (iii) Define age structure, death rate and birth rate.
    → Age structure: Proportion of different age groups in population.
    Birth rate: Live births per 1000 persons per year.
    Death rate: Deaths per 1000 persons per year.

    (iv) How is migration a determinant factor of population change?
    → Migration changes size, composition, and distribution of population. Internal migration redistributes people; international migration alters population size.


    Q3. Distinguish between population growth and population change.

    • Growth: Increase in number of people.

    • Change: Includes growth plus changes in distribution, composition, and migration.


    Q4. Relation between occupational structure and development.
    → Higher proportion in secondary/tertiary = more developed economy. Primary sector dominance = less development.


    Q5. Advantages of a healthy population.
    → Greater productivity, better quality of life, lower healthcare costs, improved economic growth.


    Q6. Significant features of National Population Policy 2000.
    → Universal free education up to 14 years, reduced infant mortality, universal immunisation, delayed marriage of girls, voluntary family welfare programs.


    Long Answer Questions

    Q1. Describe the size and distribution of India’s population.
    India’s population in 2011 was 1.21 billion, about 17% of the world’s population, spread over 3.28 million sq km. This makes India the second most populous country. Population distribution is highly uneven. Uttar Pradesh has 199 million people, the highest among states, while Sikkim and Lakshadweep have less than a million. Half of India’s population lives in just five states: Uttar Pradesh, Maharashtra, Bihar, West Bengal, and Andhra Pradesh. Population density is 382 persons/sq km on average, but varies from 1,102 in Bihar to only 17 in Arunachal Pradesh. Fertile plains and coastal regions are densely populated, while deserts, mountains, and forests are sparsely populated. This unevenness shows how geography influences human settlement.


    Q2. Discuss population growth trends in India since 1951.
    In 1951, India had 361 million people. Since then, population has increased steadily. Growth accelerated from 1951 to 1981, with rates peaking at 2.2% per year due to high birth rates and declining death rates. From 1981 onwards, growth rate declined gradually as fertility declined, but absolute increase remained high due to a large base population. For example, in the 1990s alone, 182 million people were added despite falling growth rates. By 2011, population reached 1.21 billion, and by 2023 India overtook China as the most populous nation. This shows that even with slower growth, the absolute additions remain large because of the sheer population base.


    Q3. Explain the role of migration in population change in India.
    Migration significantly affects population distribution and composition. Internal migration in India is mainly rural-to-urban due to push factors like poverty and unemployment and pull factors like jobs and better facilities in cities. This increases urbanisation; urban population grew from 17% in 1951 to over 31% in 2011, and continues rising. Migration also changes age and sex composition: men often migrate first, leaving women behind, while in cities, working-age groups dominate. International migration has also shaped India—large-scale emigration to Gulf countries and Western nations brings remittances, while immigration from neighbouring countries like Nepal or Bangladesh adds to diversity. Thus, migration redistributes population and impacts economy and society.


    Q4. Why is the adolescent population important for India?
    Adolescents (10–19 years) form one-fifth of India’s population. They are the future workforce and hold the key to economic growth. Proper nutrition and education are vital for them. However, many adolescents, especially girls, suffer from anaemia, malnutrition, and lack of healthcare. If neglected, this segment can become a burden instead of a resource. The government aims to improve adolescent health through literacy, awareness, and nutrition programs. Skilled, healthy adolescents can contribute to innovation, productivity, and nation-building. Hence, investment in this group ensures long-term development and prosperity for India.


    Q5. What are the objectives of National Population Policy 2000? Why is it significant?
    The NPP 2000 provides a comprehensive framework for family welfare and population stabilisation. Its key objectives include: universal free education up to 14 years, reducing infant mortality below 30 per 1000, universal immunisation of children, promoting delayed marriage for girls, voluntary family planning, and making reproductive healthcare accessible. The policy recognises that smaller, healthier families improve quality of life. It also focuses on adolescent health, raising awareness among girls, and ensuring nutrition and education. The significance of NPP lies in balancing population growth with sustainable development. By empowering individuals to plan families voluntarily, it links health, education, and gender equality with demographic goals.

    (i) Flora and Fauna

    • Flora: Plants of a region.

    • Fauna: Animals of a region.

    (ii) Tropical Evergreen and Deciduous forests

    • Evergreen: Found in >200 cm rainfall, trees shed leaves at different times, always green.

    • Deciduous: Found in 70–200 cm rainfall, trees shed leaves in dry summer, dominant in India.


    Q4. Types of vegetation in India; describe vegetation of high altitudes.
    → Five types: Tropical evergreen, tropical deciduous, thorny forests, montane forests, mangroves.

    • High altitudes (Montane forests): Vegetation changes with altitude. Up to 2000 m: broadleaf trees (oak, chestnut). Between 1500–3000 m: conifers (pine, deodar, cedar). Above 3600 m: alpine grasslands and shrubs, merging into tundra with mosses and lichens.


    Q5. Why are some plants and animals endangered in India?
    → Hunting, deforestation, pollution, industrialisation, expansion of agriculture, and introduction of alien species have led to habitat loss. Overexploitation disturbs ecosystems, making many species endangered or extinct.


    Q6. Why does India have a rich heritage of flora and fauna?
    → Due to varied relief (mountains, plateaus, coasts), different soils, climatic diversity, monsoon influence, and long evolutionary history. Together these factors give India one of the richest biodiversities in the world.


    Long Answer Questions

    Q1. Describe the major types of vegetation in India.
    India has five major vegetation types. Tropical Evergreen Forests are found in areas with over 200 cm rainfall, such as Western Ghats and Andamans, with trees like ebony and mahogany. Tropical Deciduous Forests are the most widespread, found in 70–200 cm rainfall zones, with teak, sal, and shisham. Tropical Thorn Forests grow in areas with less than 70 cm rainfall, such as Rajasthan, with cacti and acacia. Montane Forests change with altitude: oak and chestnut up to 2000 m, conifers up to 3000 m, and alpine vegetation above. Mangrove Forests are found in coastal deltas, with trees like sundari. This variety makes India’s vegetation diverse and rich.


    Q2. Explain the importance of forests and wildlife for human beings.
    Forests and wildlife are vital for ecological balance and human survival. Forests provide oxygen, purify air, regulate climate, prevent soil erosion, and conserve water. They are also a source of timber, fuel, fodder, and medicinal plants. Wildlife maintains the food chain, supports pollination, and enriches biodiversity. Animals like cows, buffaloes, and camels provide milk, draught power, and transport. Fish and birds provide food, while insects help pollinate crops. Loss of forests and wildlife disturbs ecosystems, causing floods, droughts, and climate change. Thus, their conservation is essential for present and future generations.


    Q3. Discuss the Montane forests and their fauna.
    Montane forests develop in mountainous regions where temperature decreases with altitude. Between 1000–2000 m, wet temperate broadleaf trees like oak and chestnut grow. Between 1500–3000 m, coniferous forests with pine, cedar, and deodar dominate. Above 3600 m, alpine vegetation with shrubs, grasses, mosses, and lichens is found. These zones are also grazing grounds for nomads like Gujjars. Fauna here include snow leopard, yak, Tibetan antelope, red panda, ibex, and wild sheep, adapted to cold climates. This gradual change from tropical to tundra vegetation makes montane forests unique.


    Q4. What measures has India taken to conserve flora and fauna?
    India has implemented several conservation measures. The Wildlife Protection Act (1972) created National Parks, Sanctuaries, and Biosphere Reserves. Today, there are 106 National Parks and 573 sanctuaries. Projects like Project Tiger, Project Rhino, and Project Elephant protect specific species. India has 18 biosphere reserves, 12 of which are in UNESCO’s world network (e.g., Sundarbans, Nanda Devi). Botanical gardens receive support, and awareness campaigns encourage afforestation and wildlife protection. Such measures aim to protect endangered species, restore ecosystems, and conserve biodiversity for sustainable development.


    Q5. Why is biodiversity conservation necessary?
    Biodiversity conservation is necessary because every species plays a role in ecosystems. Plants provide food, oxygen, and medicine. Animals maintain ecological balance by controlling populations of other species and aiding pollination. Humans depend on biodiversity for agriculture, resources, and livelihood. Loss of species causes imbalance, leading to floods, droughts, and climate change. India’s 1,300 endangered plants and many threatened animals show urgent need for conservation. Protecting biodiversity ensures food security, ecological stability, and sustainable development for future generations.

    Q2. Answer briefly:

    (i) Controls affecting climate of India → Latitude, altitude, pressure & winds, distance from sea, ocean currents, relief.

    (ii) Why monsoon type of climate? → Seasonal reversal of winds; India’s unique location, Himalayas blocking cold winds, ITCZ shifts.

    (iii) Highest diurnal range of temperature? → Thar Desert (hot days, cold nights) because of arid conditions.

    (iv) Which winds bring rainfall along Malabar coast? → South-West Monsoon winds.

    (v) Define monsoon. What is “break” in monsoon? → Monsoon = seasonal reversal of winds. Break = wet/dry spells during rainy season.

    (vi) Why monsoon as unifying bond? → Despite diversity, agriculture, festivals, life, economy revolve around rains across India.


    Q3. Why rainfall decreases east to west in Northern India?
    → Monsoon winds from Bay of Bengal shed most moisture in east; progressively less as they move westward.

    Long Answer Questions

    Q1. Explain the size and extent of India.
    Answer: India has an area of 3.28 million sq. km, about 2.4% of world’s land area, making it the seventh largest country. The mainland stretches between latitudes 8°4′N and 37°6′N and longitudes 68°7′E and 97°25′E. Its north-south extent is 3,214 km and east-west extent is 2,933 km. India has a land boundary of 15,200 km and coastline of 7,516.6 km. The Tropic of Cancer (23°30′N) divides the country into almost two halves.


    Q2. Describe India’s neighbours and its political boundaries.
    Answer: India shares boundaries with Pakistan and Afghanistan (northwest), China, Nepal, Bhutan (north), and Bangladesh and Myanmar (east). Across the sea, India’s neighbours are Sri Lanka and Maldives. In South Asia, India occupies a central position with 28 states and 8 Union Territories. Its vast boundary connects it politically, economically, and culturally with neighbouring countries.


    Q3. How has India’s central location helped in establishing cultural and trade contacts?
    Answer: India’s location between East and West Asia made it a crossroads of trade and culture. Ancient land routes across mountain passes helped exchange of goods, like spices, muslin, and ideas like numerals and the decimal system. Sea routes via the Indian Ocean linked India with Southeast Asia, Africa, and Europe. India influenced and absorbed cultures such as Greek sculpture and West Asian architectural styles, making it a centre of interaction.


    Q4. Discuss the importance of Standard Meridian of India.
    Answer: India’s vast longitudinal spread (30°) causes time differences of about 2 hours between Arunachal Pradesh and Gujarat. To avoid confusion, 82°30′E longitude (through Mirzapur, UP) is chosen as the Standard Meridian. It ensures uniformity of time across India and is called Indian Standard Time (IST). Without it, time differences would disrupt communication, travel, and administration.


    Q5. Explain how India’s geographical features influence its contacts with the world.
    Answer: The Himalayas in the north provide a natural barrier but also mountain passes for ancient contacts. The long coastline facilitated maritime trade. India’s peninsular location makes it project into the Indian Ocean, linking West Asia, Africa, and Europe with Southeast Asia and East Asia. This strategic location allowed India to play a major role in global trade, culture, and history.
