  3. 2 CBSE Class 10 Social Notes Geography 1. 1. Resources and development Resources and development Technical terms Natural Resources: Natural endowments in the form of land, water, vegetation and mineral are termed as natural resources. Human made Resources: Resources created by humans such as engineering technology, machines, buildings, monuments, paintings, social institutions etc. are called human-made or human or cultural resources. Resource Planning: Technique or skill of proper utilization of resources is termed as resource planning. Growing Season: The period of the year in which crops are sown, grown and harvested, is known as growing season. Gully Erosion: The spectacular type of soil erosion in which gullies, occur in the soil surface rendering it useless for cultivation is known as gully erosion. Net Sown Area: Net sown area is the total area sown with crops in a country. Area sown more than once is counted once only. Cultivated Land: The land which is continuously under cultivation is termed as cultivated land. Cultivable Waste: Cultivable waste is the land which has remained waste for years together because it has become infertile and eroded, but can be brought under plough again by using modem techniques. Shelter belts: Planting trees to create shelter breaks up the force of the wind. Rows of such trees are called shelter belts. Pastures: Pastures are the portions of the land covered with grass, shrubs on which animals are grazed freely in the natural environment. Important points Resources are everything available in the environment such as mineral, labor, livestock etc. that can be used to satisfy our needs. Types of Resources (i) On the basis of origin: NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  4. 3 CBSE Class 10 Social Notes Geography Biotic: Resources obtained from biosphere and are living. For example: flora, fauna, fisheries, livestock and humans. Abiotic: Non-living things in the environment. For example: rocks and metals. (ii) On the basis of exhaustibility: Renewable Resources: Resources which have ability to renew themselves and can be reproduced by physical, chemical or mechanical processes. For example: Solar energy, wind energy, water, forests and wildlife. Non-Renewable Resources: The resources which formed after a very long geological time (millions of years) are known as non-renewable resources. In other words, resources which cannot be remade in the present-age. For example: Minerals Metals Recyclable Fossil Fuels Non-recyclable (iii) On the basis of ownership: Individual Resources: The resources which are owned by people individually are termed as individual resources. For example: Houses, Plots, farm lands etc. Community owned Resources: These resources are accessible to all members of the community. For example: Village ponds, picnic spots, grazing grounds etc. National Resources: These resources are accessible to all citizens of nation. For example: Roads, railways, canals etc. International Resources: These resources can be used by all nations of the world. For example: Exclusive Economic Zone beyond 200 km (oceanic resources). (iv) On the basis of status of development: NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  5. 4 CBSE Class 10 Social Notes Geography Potential Resources: These resources are available in a region, but have not been utilized till yet. For example: The western pa-t of India (Rajasthan and Gujarat) has great potential for the development of wind and solar energy. Developed Resources: These resources are surveyed and their quality and quantity have been determined for utilization. Stock: The resources which have potential to satisfy human needs but people do not have the appropriate technology to access these. Reserves: The subset of stock which can be access with the help of existing technology but their use has not been started. Probably they me for meeting future requirements.  Resources are vital for human survival and maintaining the quality of life.  Excessive and indiscriminate use of resources has created major problems.  Therefore resource planning is essential for sustainable existence of all forms of life.  Sustainable existence is a component of sustainable development.  In June 1992, more than 100 heads of states met for the first International Earth Summit in Rio de Janeiro.  In a country like India, it is very important to make and execute resource planning, where there is a great diversity in the availability of resources.  The states of Jharkhand, Chhattisgarh and Madhya, Pradesh are rich in minerals and coal deposits.  Arunachal Pradesh has abundance of water resources but lacks in infrastructural development.  The state of Rajasthan is very well endowed with solar and wind energy but lacks in water resources.  The cold desert of Ladakh has very rich cultural heritage but deficient in water infrastructure and some vital minerals. In other words, it is relatively isolated from the rest of country.  Above diversity points out for balanced resource planning at the national, state, regional and local levels.  Resource planning is a complex process which involves: identification and inventory of resources across the regions of the country. It involves surveying, mapping and qualitative and quantitative estimation and measurement of the resources. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  6. 5 CBSE Class 10 Social Notes Geography Resource conservation at various levels is very vital to overcome the problems caused due to irrational consumption and over utilization of resources. The club of Rome advocated resource conservation for the first time in 1968. In 1974, Gandhian Philosophy was presented by Schumacher in his book ‘Small is Beautiful’. In 1987, the seminal contribution at the global level was made by the Brundtland, Commission Report. Land is a vital natural resource which supports natural vegetation, wildlife, human life, economic activities, and transport and communication systems. Due to the finite magnitude of land, careful planning is necessary in using the available land. India had following land relief features: - Plains (43%) - Mountains (30%) - Plateau region (27%). Land Utilization Utilization of land resources is in the following: (i) Forests (ii) Land not available for cultivation - Barren and waste land - Non-agricultural land, e.g., buildings, roads, factories etc. (iii) Other cultivated land excluding fallow land (iv) Fallow lands (v) Net sown area Land use is determined by the following factors: (i) Physical factors: Topography, climate, soil types. (ii) Human factors: Population density, technological capability and culture and tradition. Land use Pattern in India Total geographical area of India is 32.8 million sq. km. - The land under pastures has decreased. - Most of the land (other than the current fallow lands) is either of poor quality or the cost of cultivation of such land is very high. NSA varies greatly from one state to another. - Punjab and Haryana: NSA—80% NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  7. 6 CBSE Class 10 Social Notes Geography - Arunachal Pradesh, Mizoram, Manipur, and Andaman and Nicobar Islands: NSA—10%. Forest area is less than the desired 33% of the geographical area. Land Degradation and Conservation Measures Continuous use of land over a long period of time without taking proper measures to conserve and manage it, resulted in land degradation. Degraded land - Forest degraded area (28 million hectares) - Water eroded area (56 million hectares) - Saline and alkaline deposits (116 million hectares) Land is degraded by some human activities such as deforestation, overgrazing by cattles, mining and quarrying. 1.Methods to Overcome the Problem of Land Degradation 2.Afforestation and proper management of grazing. 3.Planting shelter belts 4.Control on overgrazing 5.Stabilization of sand dunes by growing thorny bushes 6.Proper management of wastelands 7.Control on mining activities 8.Proper discharge and disposal of industrial effluents after treatment. Soil as a Resource Important factors in the formation of soil are: (i)Relief, parent rock or bed rock (ii)Climate (iii)Vegetation and other forms of life Other factors are change in temperature, actions of running water, wind and glaciers, activities of decomposers and chemical and organic changes takes place in the soil. Classification of Soils Various relief features, landforms, climatic realms and vegetation types contribute in the development of various types of soils. 1.Alluvial soils 2.Black soil 3.Red and yellow soil 4.Laterite soil 5.Arid soils 6.Forest soil NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  8. 7 CBSE Class 10 Social Notes Geography Soil erosion and conservation The removal of top fertile soil is called soil erosion. Factors responsible for soil erosion: (i)Natural factor: wind, glacier and water (ii)Human factor: deforestation, over-grazing construction and mining. (iii)Other factor: defective methods of farming, ploughing in a wrong way. Effective measures to control soil erosions are: 1.Contour ploughing 2.Terrace cultivation 3.Strip cropping 4.Shelter belts 2. 2. Forest Forest and and Wildlife Resources Wildlife Resources Technical Terms Flora: All types of flowering and non-flowering plants and grass, trees, scrubs and shrubs form flora. Fauna: All life forms from microbes bacteria to elephant constitute fauna. Wildlife Sanctuaries: Wildlife sanctuaries are the portion of the natural forests where hunting and poaching of wild animals and birds are prohibited. Example: Bird Sanctuary Bharatpur. Zoological Parks: Zoological Parks are reserved gardens where wild animals are kept in man- made surroundings according to their natural habits. Example: Delhi Zoo. Critical Species: Species on the verge of extinction are termed as critical species. Example: Cheetah, Mountain quail. Important Points Our entire habitat has immense bio-diversity. Humans along with all living organisms form a complex web of ecological system in which we are a mere part of it and very much dependent on this system for our own existence. Bio-diversity or Biological Diversity is immensely rich in wildlife and cultivated species. Flora and Fauna in India NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  9. 8 CBSE Class 10 Social Notes Geography India is one of the world’s richest countries in terms of vast range of bio-diversity; It has about 8% of the total number of species in the world (estimated to the 1.8 million). India has 81000 species of fauna and 47000 species of flora. About 15000 species of flowering plant in fauna are endemic (indigenous) to India, Species. (i)Normal species (ii)Endangered species (iii)any Vulnerable species (iv)Rare species (v)Endemic species (vi)Extinct species Factors Responsible For Depletion of Flora and Fauna Expansion of the railways, agriculture, commercial and scientific forestry and mining activities leads to depletion of our forests during cloning period. Agricultural expansion: During 1951-1980 over 26,200 sq. km of finest area was converted into agricultural land. Enrichment Plantation: in which a single commercially valuable species was extensively planted and other species eliminated. Example: Teak monoculture has damaged the natural forest in South India. Large Scale Development Projects: Clearing of forests is still continuing with projects like the Narmada Sagar Project. Mining: The Buxa Tiger Reserve in West Bengal is seriously threatened by the ongoing dolomite mining. Habitat destruction: hunting, poaching, over-exploitation, environmental pollution, poisoning and forest fire are factors led to decline in India’s biodiversity. Necessity of Conservation of Forest and Wildlife Rapid decline in wildlife population and forestry has made conservation essential. Conservation preserves the ecological diversity and our life support system—water, air and soil. It also preserves the genetic diversity of plants and animals for better species growth and breeding. Acts Implemented for Conservation of Wildlife The Indian Wildlife Protection Act 1972. Notification under Wildlife Act 1980 and 1986. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  10. 9 CBSE Class 10 Social Notes Geography Project Tiger “Project Tiger” was launched in 1973. At present there are 53 Tiger Reserves in the country (as on 21 June 2011). Some of the major tiger reserves are: Corbett National Park, Uttarakhand Sundarban National Park, West Bengal Bhandhavgarh National Park, Madhya Pradesh Manas Tiger Reserve, Assam Periyar Tiger Reserve, Kerala Kanha National Park, Madhya Pradesh. Types and Distribution of Forest and Wildlife Resources Reserved Forests: These forests are regarded as the most valuable from the point of conservation of forests and wildlife resources. Protected Forests: These forests lands are protected from any further depletion. Unclassed Forests: These are other forests and wastelands. They belong to both government and private individuals and communities. Distribution of Forests Madhya Pradesh has the largest area under permanent forests. Unclassed forests are situated in the north-eastern states of India and Gujarat. Mangrove forests are found in Sundarban Delta and Deltas of east flowing rivers of the peninsular plateau. 4. Community and Conservation Local communities are struggling to conserve forests along with government officials in some places of India. In Sariska Tiger Reserve Rajasthan, villagers have fought against mining by citing the Wildlife Protection Act. The inhabitants of five villagers in the Alwar district of Rajasthan have declared 1200 hectares of forests as Bhairodev Dakav “Sonchuri” declaring their own set of rules and regulations. Several virgin forests are preserved in pristine form named as Sacred Groves. These forests have left untouched by the local people and any interference with- them is banned. Trees are preserved in the name of worship by many communities. Some animals are also an integral part of the community and nobody can harm them. Examples of such animals are Monkeys, Blackbuck, Nilgai and Peacock etc. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  11. 10 CBSE Class 10 Social Notes Geography Involvement of Local Communities ‘Natural Resource’ Management Chipko Andolan in Himalayas successfully resisted deforestation and encourage afforestation. Beej Bachao Andolan in Tehri and Navdanya proved adequate levels of diversified crop production without use of synthetic chemicals. In India Joint Forest Management (JFM) involves local communities in management and restoration of degraded forests. 3. 3. Water Resources Water Resources Technical Terms Floods: Inundation of large areas beyond the bank of rivers is termed as floods. Hydrological Cycle: Movement of water through lithosphere, atmosphere and hydrosphere is known as hydrological cycle. Precipitation: Falling of moisture after condensation in the form of droplets, rain, snow and hailstones is called as precipitation. Scarcity of Water: Shortage of water to meet the basic requirements of the people is called scarcity of water. Ground Water: The portion of water which percolates into the ground and gets stored into the aquifers is referred to as the ground water. Hydroelectric Power: Power obtained through moving the turbines by the pressure of water obtained due to the difference of height, is termed as hydroelectric power or hydel power. Hydraulic Structures: Structures built for storing rainwater are termed as hydraulic structures. Examples: Baoli, tanks, village, johads, etc. Dams: Concrete structures which are built across rivers to impound water in reservoirs are called dams. Example: Sardar Sarovar Dam, Bhakra Dam. Multi-purpose Projects: Projects which serve more than two purposes simultaneously are called multi-purpose projects. Example: Damodar valley corporation. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  12. 11 CBSE Class 10 Social Notes Geography Palar Pani: The rainwater collected in storage during rainfall is termed as palar pani, and is the purest form of natural water. Inundation Canal: It is meant to direct flood water during the rainy season. Important Points 1. Some Facts and Figures About Water Three-fourth of the earth surface is covered with water. But only a small proportion of it accounts for fresh water. 96.5% of the total volume of water in the world is estimated to exist in oceans. Only 2.5% exists as fresh water. Nearby 70% of this fresh water is confined in ice sheets and glaciers in Antarctica, Greenland and the mountainous regions of the world. A little less than 30% is stored as ground water in the world’s aquifers. So total % of total water available as ground water = 0.7425. Total water (90% total) 96.5% in oceans 2.5% fresh water 70% of this confined as snow in different form 30% of this as ground water India receives nearly 4% of the global precipitation. India ranks 133 in the world in terms of water availability per person per annum. The total renewable water resources of India are estimated at 1191 cubic kilo-meter (in 2011) per annum. By 2025 large parts of India will face absolute water scarcity. 2. Water Scarcity and The Need for Water Conservation and Management Water scarcity is associated with regions having low rainfall or those that are drought prone. Availability of water resources varies over space and time, mainly due to the variations in seasonal and annual precipitation. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  13. 12 CBSE Class 10 Social Notes Geography Causes Over Exploitation: Farmers having their own well and tube-well leads to a fall in ground water level. Industrialization and Urbanization: (i)Causes heavy use of water. (ii)Multiplying urban centres with large population and urban lifestyles aggravated this problem. Bad Quality of Water Bad quality of water is due to the following: (i)Domestic and industrial waste. (ii)Chemicals and pesticides used in agriculture. (iii)Sewage flow into rivers and canals. (iv) Garbage dumping near water bodies. Conservation of Water Resources Conservation and management of water resources help in the following way: (i)to safeguard ourselves from health hazard. (ii)to ensure food security. (iii)continuation of our livelihood and productive activities. (iv)to prevent degradation of our natural ecosystems. 3. Multi-Purpose River Projects and Integrated Water Resources Management Sophisticated hydraulic structures like dams built of stone rubble, reservoirs or lakes, embankments and canals for irrigation have been constructed from ancient times in India to conserve and manage water. Dams are a barrier across flowing water that obstructs, directs or retards the flow, often creating a reservoir, lake or impoundment. Now dams were built for power generation, water supply for domestic and industrial use, flood control, recreation, inland navigation and fish breeding. Hence dams are called multi-purpose projects. Examples: BhakraBhakra Project, Hirakud Project. Adverse Effects of Dams/Multi-Purpose Projects (i)Regulating and damming of rivers affect the natural flow of water causing poor sediment flow and NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  14. 13 CBSE Class 10 Social Notes Geography excessive sedimentation at the bottom of the reservoir. Dams also fragment rivers making it difficult for aquatic fauna to Migrate, especially for spawning. (ii)The reservoirs created on the flood plains also submerge the existing vegetation and soil leading to its decomposition over a period of time. (iii)Large scale displacement of local communities, as a result of which movements like the Narmada Bachao Andolan and Tehri Dam Andolan etc., came into existence. Narmada Bachao Andolan Narmada Bachao Andolan is non-government organization (NGO). It has mobilized tribal people, farmers; environmentalist against the Sardar Sarovar Dam built across the Narmada river in Gujarat. It is originally focused on the environmental issues related to trees that would be submerged under the dam water. Now it has re-focused the aim to enable the poor citizens (displaced people) to get full rehabilitation facilities from the government. 4. Rainwater Harvesting Rainwater harvesting is accumulating and storing of rainwater. It is a technique for capturing and storing rainwater through hydro-structures. Rooftop Rainwater Harvesting It is the most common practice in Shillong, Meghalaya. Almost every household has a rooftop rainwater harvesting structure. Advantages of Rainwater Harvesting Water security Lower water supply cost Relief of strain on other water supply resources Reduce flood flow Bamboo Drip Irrigation System In Meghalaya, a 200-year old system of tapping stream and spring water by using bamboo pipes is very common. Nearly 18 - 20 litres of water enter the bamboo pipe system, get transported over hundreds of metres and finally reduces to 20-80 drops per minute at the site of the plant. Today, rooftop rainwater harvesting system is successfully adopted in Gendathur a village of Mysore (Karnataka). Tamil Nadu is the first and the only state in India which has made rooftop rainwater harvesting structure compulsory to all the houses across the state.

  15. 14 CBSE Class 10 Social Notes Geography 4. 4. AGRICULTURE AGRICULTURE Technical Terms Subsistence Agriculture: The agricultural practice which involves the farmer and his family to produce and raise crops for home consumption is known as subsistence agriculture. Shifting Agriculture: Shifting agriculture is that agriculture in which farmers go on shifting from one land to another after a period of two to three years due to decrease in soil fertility. Intensive Subsistence Farming :Intensive subsistence farming is that farming in which yield per unit area is high due to use of irrigational facilities, use of fertilizers, insecticides, pesticides, improved seeds, high yielding varieties of seeds, use of machines and other implements. Farmers produce enough for their own consumption and remaining produce is used for exchange against to other goods. Commercial Farming: Commercial farming is that type of farming in which higher doses of modern technology like HYV seeds, chemical fertilizers, insecticides and pesticides and assured irrigation are used to obtain higher productivity and production. Green Revolution: Due to application of modem techniques and assured canal and tube well irrigation, production of food grains has increased tremendously especially wheat in Punjab, Haryana and western Uttar Pradesh between 1965 to 1975. This is called green revolution. Horticulture: Intensive cultivation of vegetables, fruits and flowers. Sericulture: Sericulture is a labour intensive industry which involves rearing of silk worms and producing silk. White Revolution (Operation Flood): White revolution is the programme under which milk production is augmented in order to raise the poor people above from the poverty line. Biotechnology: Use of biological agents and process for beneficial purpose is known as biotechnology. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  16. 15 CBSE Class 10 Social Notes Geography Important Points 1. Types of Farming (i) Primitive Subsistence Farming: It is “slashand burn” agriculture. Farmers clear a patch of land and produce cereals and other food crops to sustain themselves. When soil fertility decreases, the farmer shift and clear a fresh patch of land to cultivate. This type of shifting allows the nature to replenish the fertility of the soil through the natural processes. (ii) Intensive Subsistence Farming: It is labour-intensive farming. In this farming high dose of biochemical inputs and irrigation are used for obtaining higher production. (iii)Commercial Farming: The main features of this type of farming are the use of higher dose of modem inputs. Generally the degree of commercialization varies from one region to another. Example: Rice is commercial crop in Punjab and Haryana. But subsistence crop in Odessa. (iv)Plantation Farming: Plantation is a type of commercial farming. In this farming, a single crop is grown on a large area. The plantation has an interface of agriculture and industry. In India tea, coffee, rubber, sugarcane, jute, apple,-orange, banana etc. are important plantation crops. 2. Cropping Pattern (i)Rabi: Crops are sown in winter from October to December and are harvested in summer from April to June. Wheat, barley, etc. are important crop of this season. (ii)Kharif: Crops are grown with the outset of monsoon in different parts of the country in September-October. Important crop growing this season are paddy, maize, jowar, etc. (iii)Zaid: Crops are short crop growing season between rabi and the kharif season during summer months. Watermelon, muskmelon, cucumber, vegetables and fodder crops are zaid crops. 3. Major Crops Rice: India is the second largest producer of rice in the world. It is chiefy grown in north and north-eastern India, coastal areas and deltaic region. Wheat: India stands fifth among the wheat producing countries. It is largely grown in North- India—U.P., Punjab, Haryana, Rajasthan, Bihar and Madhya Pradesh. Millets: Jowar, bajra and ragi are the main millets grown in India. These are called as coarse grains, but they have very high nutritional value. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  17. 16 CBSE Class 10 Social Notes Geography Maize: It grows well in old alluvial soil. Major maize producing states are Karnataka, Uttar Pradesh, Bihar, Andhra Pradesh and Madhya Pradesh. Pulses: India stands first both in respect of pulses production and their consumption. These are grown in Madhya Pradesh, Uttar Pradesh, Rajasthan, Maharashtra and Karnataka. Food Crops Other than Grains (i) Sugarcane: India is a native place of sugarcane. It stands second after Brazil in the world in respect of its production. It is a crop of tropical as well as a subtropical regions. Its production states are Uttar Pradesh, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh, Bihar, Punjab and Haryana. (ii) Oil Seeds: Principal oil seeds include groundnuts, rapeseeds and mustard seeds. Others are sesanmm, linseeds, castor seeds, sunflower seeds, cotton seeds and copra (coconut). (iii) Groundnut: It is a Kharif Crop. It accounts about half of the major oil seeds produced in the country. Its largest producer is Gujarat followed by Andhra Pradesh and Tamil Nadu. Beverage Crops (i)Tea: India is the leading producer of tea after China. Warm and moist climate is ideal for its cultivation. Tea plantation is found chiefly in Assam, Sikkim, Darjeeling and Jalpaiguri districts of West Bengal, Tamil Nadu and Kerala. Other producing states are Himachal Pradesh, Uttarakhand, Meghalaya, Andhra Pradesh, and Tripura. (ii)Coffee: India produced about 4% of the world’s coffee production. Coffee cultivation is mainly confined to Southern states like Karnataka, Kerala and Tamil Nadu. Horticulture Crops Horticulture Crops India is the second largest producer of fruits and vegetables in the world after China. India is a producer of tropical as well as temperate fruits. India produces about 15% of the world’s vegetables. It is an important producer of pea, cauliflower, cabbage, onion, tomato, brinjal and potato. Major fruits produced in India are apple, mango, banana, grapes, orange, lichi, guava etc. 4. Non Food Crops (i)Rubber: It requires moist and humid climate with rainfall above 200 cm. It is mainly grown in Kerala, Tamil Nadu, Karnataka, and Andaman and Nicobar Islands and Garo hills of Meghalaya. (ii)Fiber crops: Cotton, jute, hemp and natural silk are four major fibre crops grown in India. (iii)Cotton: It required high temperature, light rainfall, 210 frost-free days and bright sunshine for its growth. Major cotton producing states are—Maharashtra, Gujarat, Madhya Pradesh, Karnataka, Andhra Pradesh, Tamil Nadu, Punjab, Haryana and Uttar Pradesh. (iv)Jute: It grows well on well-drained fertile soil in the flood plains. West Bengal, Bihar, Assam, Orissa and Meghalaya are the major jute producing states.

  18. 17 CBSE Class 10 Social Notes Geography 5. Technological and Institutional Reforms After independence following technological and institutional reforms were introduced: (i)Collective farming: In this method fields of several farmers are joined together and member- owners engage jointly in farming activities. (ii)Land holdings were consolidated: Fragmented land due to inheritance was again consolidated into single unit to increase its economic liability. (iii)Zamindari system was abolished. (iv)The Green Revolution based on the use of package technology and White Revolution (Operation Flood) was initiated to improve Indian agriculture. (v)In 1980s and 1990s a comprehensive land development programme was initiated which include: Crop insurance Grameen banks, Cooperative societies and banks Kisan Credit Card (KCC), Personal Accident Insurance Scheme (PAIS) Weather bulletins and agricultural programmes Minimum Support Price, remunerative and procurement. (vi)Bhoodan Gramdan: Due to the efforts of Vinoba Bhave voluntary redistribution of farm lands to poor landless farmers for their economic well-being was started. This is called Bhoodan gramdan. 6. Contribution of Agriculture to The National Economy, Employment and Output Agriculture has been the backbone of the Indian economy. It provides employment and livelihood to 52% population. Government establish Indian council of Agricultural Research (ICAR), agricultural universities, veterinary services and animal breeding centers, horticulture development, research and development in the field of meteorology and weather forecast to modernize agriculture. Though the GDP growth rate is increasing over the years, but it is not generating employment opportunities in the country. Indian farmers are facing a big challenge from international competition. 7. Food Security In order to ensure availability of food to all sections of society, our government designed a national food security system. It comprises of two components: (i)Buffer Stock (ii)Public Distribution System (PDS) 8. Impact of Globalization on Agriculture Under globalization after 1990, Indian farmers are not able to compete with the developed countries. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  19. 18 CBSE Class 10 Social Notes Geography Today genetic engineering is recognized as a powerful supplement in inventing new hybrid varieties of seeds. Organic farming is much in vogue today as it is environment friendly. Indian farmers should diversify their cropping pattern from cereals to high value crops. 5. 5. Minerals a Minerals and Energy Resources nd Energy Resources Technical Terms Mineral: Mineral is a homogeneous, naturally occurring substance with a definable internal structure. Mining: Mining is an economic activity of extracting minerals from the earth. Examples: Mining of petroleum, iron, bauxite, etc. Ferro Alloys: Ferro alloys are mixed metals with iron as the base. Fossil Fuels: The fuels formed because of the decomposition of organism in the sedimentary rocks are called fossil fuels. Ferrous Minerals: Minerals having iron contents are known as ferrous minerals. Examples: Iron, manganese. Non-ferrous Minerals: Minerals which do not have iron contents are non-ferrous minerals. Examples: Gold, silver, copper, lead. Off-shore Drilling: Off-shore drilling is the process of drilling mineral oil from the sea bed, off from the shore, by drilling at the bottom of the sea. Metallic Minerals: Minerals comprising of metal contents are metallic minerals. Examples: Iron-ore, bauxite, copper, gold, etc. Non-metallic Minerals: Minerals which do not have metal contents are non-metallic minerals. Examples: Limestone, potash, nitrate. Shaft-mines: Deep and tunnelled mines are called shaft mines. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  20. 19 CBSE Class 10 Social Notes Geography Placer Deposits: Minerals occurring as alluvial deposits in sands of valley floors and at the base of hills are called placer deposits. Ore: Ore is the mineral mixed with other elements or impurities. Example: Iron ore. Mineral Deposit or Reserve: Known mineral concentration under the ground is called mineral deposit or reserve. Example: Petroleum deposits in Assam and Gujarat. Important Points Earth’s crust is made up of different minerals embedded in the rocks. Rocks are combination of homogenous substances called minerals. The properties on which classification of minerals depends are as follows: (i)wide range of colours (ii)hardness (iii)crystal forms (iv)lusture and (v)density Classification of Minerals Minerals Energy minerals e.g., coal, petroleum, natural gas. Metallic Non-metallic e.g., mica, salt, potash, sulphur, granite, limestone, marble, sandstone etc. Ferrous (containing iron) e.g., iron ore, manganese, nickel, cobalt,etc. Non-ferrous e.g., copper, lead, tin, bauxite,etc. Precious e.g., gold, silver, platinum,etc. NCERT Solutions CBSE Sample Papers RD Sharma Solutions

  21. 20 CBSE Class 10 Social Notes Geography Mode Of Occurrence Of Minerals Minerals generally occurred in these forms: Minerals occur in the veins and the lodes in igneous and metamorphic rocks. Examples: Tin, copper, zinc and lead etc. are obtained from these veins and lodes. Minerals occur in bed or layers in sedimentary rocks. Coal and some form of iron are found in it. Bauxite is formed in the decomposed surface rocks. Generally the minerals not corroded by water are found in alluvial deposits. Examples: Gold, silver, tin and platinum. The ocean water contains vast quantities of minerals. Examples: Common salt, magnesium and bromine. Ferrous minerals: provide a strong base for the development of metallurgical industries and account for about three-fourth of the total value of the production of metallic minerals. Iron ore is the basic mineral and the backbone of industrial development. The major iron ore belts in India are: (i)Odisha—Jharkhand Belt (ii)Durg—Bastar—Chandrapur Belt (iii)Bellary—Chitradurga—Chikmaglur—Tumkur Belt. (iv)Maharashtra—Goa Belt. Manganese is mainly used in manufacturing of steel and Ferro-manganese alloy. Non-ferrous minerals include copper, bauxite, lead, zinc and gold, which play a vital role in a number of metallurgical, engineering and electrical industries. Copper: Copper producing states are Madhya Pradesh, Jharkhand and Rajasthan. Bauxite is a clay like substance.
