Long Answer Questions
26 QuestionsQ95Classify resources on the basis of four major criteria.
Answer: Resources are classified on four major bases. By origin, they are biotic and abiotic. By exhaustibility, they are renewable and non-renewable. By ownership, they are individual, community-owned, national and international. By status of development, they are potential, developed, stock and reserves.
Q96Explain why resource planning is essential in India.
Answer: Resource planning is essential because resources are unevenly distributed and differ in quality and availability. Some regions are rich in particular resources while others face shortages. Planning helps identify and map resources, assess their potential, develop appropriate technology and institutions, coordinate use with national priorities and promote judicious, balanced and sustainable development.
Q97Describe the main stages of resource planning in India.
Answer: First, resources are identified and inventoried through surveys, mapping and assessment. Second, appropriate planning structures are developed with suitable technology, skills and institutions. Third, resource-development plans are integrated with broader national development plans so that resource use supports wider economic and social goals.
Q98Explain the consequences of indiscriminate resource utilisation.
Answer: Indiscriminate use can lead to depletion of resources, environmental degradation, unequal access to resources and conflicts over their use. It can also increase pollution and reduce the ability of future generations to meet their needs. Sustainable and planned use is therefore necessary.
Q99Explain sustainable development and its importance.
Answer: Sustainable development seeks to meet present needs without destroying the resource base and environmental conditions needed by future generations. It is important because economic growth without conservation can create long-term environmental and resource problems. Sustainable development balances development, conservation and intergenerational responsibility.
Q100Explain the different categories of resources on the basis of ownership.
Answer: Individual resources are privately owned. Community-owned resources are available to members of a community. National resources belong to the nation and are subject to national authority. International resources lie beyond national jurisdiction and are regulated through international arrangements.
Q101Explain the classification of resources on the basis of status of development.
Answer: Potential resources are available in a region but have not been fully utilised. Developed resources have been surveyed and are currently used. Stock has potential but cannot currently be used because suitable technology is unavailable. Reserves are a part of stock that can be used with existing technology for future requirements.
Q102Explain the importance of land and the factors controlling its use.
Answer: Land supports agriculture, forests, settlements, transport and industries. Its use is controlled by physical factors such as topography, climate and soil, and by human factors such as population, technology, irrigation, infrastructure, economic activities and government policies. These factors create different land-use patterns in different regions.
Q103Explain land degradation and the major human activities responsible for it.
Answer: Land degradation is the decline of land quality and productive capacity. Deforestation removes protective vegetation; overgrazing exposes soil; mining disturbs land and removes vegetation and topsoil; over-irrigation can cause waterlogging and salinity; and industrial wastes can contaminate land and water. These activities reduce the productive and ecological value of land.
Q104Describe measures for controlling land degradation.
Answer: Afforestation restores protective vegetation. Controlled grazing reduces pressure on grasslands. Shelter belts help protect dry areas from wind erosion. Sand dunes can be stabilised with suitable vegetation. Better management and restoration of mined areas reduce mining damage. Treatment and proper disposal of industrial wastes reduce pollution.
Q105Explain soil formation and the factors that influence it.
Answer: Soil develops through the interaction of parent rock, climate, relief, vegetation and other organisms over long periods. Temperature and rainfall influence weathering and leaching, relief affects drainage and erosion, organisms add and transform organic matter, and time allows soil horizons to develop.
Q106Describe alluvial soil, including Bangar and Khadar.
Answer: Alluvial soil is formed mainly from river-deposited sediments and is widespread in the northern plains and river and delta regions. Bangar is older alluvium, generally lying above newer floodplain deposits and often containing more kankar nodules. Khadar is newer alluvium deposited more recently by rivers and is renewed by fresh deposits.
Q107Describe the main characteristics of black soil.
Answer: Black soil is widely associated with the Deccan region and is also called regur or black cotton soil. It has high moisture-retaining capacity and develops deep cracks when dry. These characteristics, together with its fertility in suitable conditions, make it particularly suitable for cotton.
Q108Describe the main features and formation of red and yellow soils.
Answer: Red and yellow soils develop on crystalline igneous rocks, especially in parts of the eastern and southern Deccan. Iron compounds contribute to their colour. Their characteristics vary with local climate, relief and parent material.
Q109Describe laterite soil and explain why it may require careful management.
Answer: Laterite soil develops under high temperature and heavy rainfall where intense leaching removes soluble nutrients. It may therefore be relatively poor in plant nutrients. With suitable management and inputs, however, it can support cultivation in appropriate areas.
Q110Describe arid soil and forest or mountain soil.
Answer: Arid soils occur mainly in arid and semi-arid regions and are often sandy, with salts in some areas. Forest or mountain soils occur in hilly and mountainous regions and vary with altitude, slope, vegetation and local climate. Their properties therefore differ considerably from place to place.
Q111Explain soil erosion, its major forms and its effects.
Answer: Soil erosion is the removal of soil by agents such as running water and wind. Gully erosion cuts deep channels, sheet erosion removes a thin layer over a broad surface, and wind erosion transports loose soil particles. Erosion removes fertile topsoil, lowers productivity and can contribute to land degradation.
Q112Explain the major methods of soil conservation.
Answer: Contour ploughing slows water on slopes. Terrace farming creates steps that reduce runoff. Strip cropping breaks the force of wind and slows water. Shelter belts reduce wind speed in dry regions. Afforestation protects soil with vegetation cover and roots. These methods reduce the removal of fertile soil.
Q113Compare renewable and non-renewable resources and explain why both require careful management.
Answer: Renewable resources can be replenished naturally, but overuse can still degrade them. Non-renewable resources occur in limited quantities or take very long periods to form. Renewable resources require sustainable rates of use, while non-renewable resources require efficient use, recycling where possible and careful planning.
Q114Explain how resource planning can support sustainable development in India.
Answer: Resource planning identifies available resources, assesses their quality and potential, coordinates technology and institutions, and integrates resource use with national development. By reducing wastage and encouraging judicious use, it helps meet present needs while protecting resources and the environment for the future.
Q115Explain why land-use patterns differ across India.
Answer: Land-use patterns differ because regions have different relief, climate, soils, water availability and vegetation. Human factors also matter: population density, settlement, irrigation, technology, infrastructure, markets and government policies influence whether land is used for farming, forests, settlements, industry or other purposes.
Q116Explain the relationship between deforestation, soil erosion and land degradation.
Answer: Deforestation removes vegetation that protects soil from wind and water. Increased runoff and wind action can then remove fertile topsoil, causing soil erosion. Continued erosion and loss of vegetation reduce land productivity and contribute to broader land degradation.
Q117Explain how human activities can both develop resources and create resource problems.
Answer: Mining, irrigation, agriculture, industry and infrastructure can make resources available for economic development. However, if these activities are poorly planned, they can cause depletion, pollution, waterlogging, salinity, deforestation and soil erosion. Development therefore needs planning, regulation and conservation.
Q118Prepare a structured answer explaining why soil conservation is important for India.
Answer: Soil supports agriculture and natural vegetation and is essential for food production. Erosion removes fertile topsoil and can reduce productivity. Since soil formation is slow, conservation is necessary to maintain fertility, reduce land degradation, protect water quality and support sustainable agriculture and livelihoods.
Q119Write a comprehensive note on Resources and Development for board revision.
Answer: The chapter explains the meaning and classification of resources, their development and the need for sustainable use. It covers resource planning in India, land resources and land-use patterns, land degradation and conservation, soil formation and the major soil groups, soil erosion and soil conservation. For examination preparation, students should master definitions, comparisons, causes and measures, soil characteristics, resource-planning stages and the prescribed soil map work.
Q120Why is conservation important even for renewable resources?
Answer: Renewable resources can be replenished, but they can still be depleted or degraded when used faster than they recover. Conservation ensures their continued availability, protects ecosystems and supports sustainable use.
