21. What are fuel minerals?22. What are multipurpose river

projects;Answers1. India, with an area of

32,87,782 sq km, is theseventh largest country afterRussia, Canada, China, USA,Brazil and Australia and thesecond most populous (nextto China) country in theworld. It extends between 8°4' and 37° 6' North latitudesand 68° 7' and 97° 25' Eastlongitudes, lying north of theequator and thus belongs toNorthern Hemisphere. TheTropic of Cancer (23° 30' N)divides the country intoalmost two equal halves.While the southern halfcoinciding with peninsularIndia lies in the tropical zone,the northern half, somewhatcontinental in nature, belongsto the subtropical zone.Situated to the east of thePrime Meridian, India alsobelongs to the EasternHemisphere.

The country is of vast size.The north-south extension ofIndia covers about 30° oflatitude or measures about3,214 km and the east-westextention covers almost 30° oflongitude or measures about2,933 km which is one-twelfthof the Earth’s circumferenceat the Equator. India has aland frontier of 15,200 km anda coastline of about 6,100 km.India takes its standard timefrom the Meridian of 82° 30'E, which is 5½ hours aheadof Greenwich Mean Time (0°longitude).

2. The rivers of northern Indiahave a perennial source ofwater, which is utilised forirrigation and producingelectricity. These riversprovide fertile soil and aregood water ways forcommunication, etc. But therivers of the Deccan are fed bythe monsoons. Most of theyear, they are mere trickles inbeds of stone and sand.

3 Jhum Cultivation is shiftingcultivation practised by thetribals of North-East India,where the farmers usuallyclear the land for planting byslashing the vegetation andburning the debris. It leads toenvironmental degradation,soil-erosion, loss of fertility ofsoil and growth of secondaryvegetation.

4. The Himalayas are of greatsignificance for the land andpeople of the subcontinent.i. Physical Barrier: The

Himalayas act as phys-ical barrier between thesubcontinent and the restof Asia.

ii. Birthplace of Rivers: Themassive snowfields andglaciers of the Himalayas

are sources of manyperennial rivers uponwhose water dependsmuch of irrigation andhydroelectric power of theIndo-Gangetic plain. Thesilt brought by these rivershave made the Indo-Gangetic plain very fertile.

iii. Influence on Climate: TheHimalayas protect theIndo-Gangetic plain fromthe bitterly cold windswhich blow from CentralAsia and Tibet duringwinter. It compels the rain-bearing winds blowingfrom the sea in the south toshed all their load of rainon the Northern plain.

iv. Flora and Fauna: Theslopes of these moun-tains are forested andprovide shelter to a widevariety of wild life.

v. Mineral Resources: TheHimalayas have comm-ercially valuable mineralssuch as copper, lead, zinc,bismith, antimony,nickel, cobalt andtungsten. They are alsothe storehouse of preci-ous and semi-preciousstones. Coal and petrol-eum are the other mineralfuels found in this region.

vi. Other Economic Resour-ces: Green pasture oflower Himalayas haveenabled sheep and goatrearing an importantoccupation.

vii. Tourist Abode: The lowerand upper range ofHimalayas, because oftheir height, enjoy a cooland pleasant climate thusattracting a large numberof tourists during springand summer seasons.

5. The Deccan Plateau extendsfrom the Vindhyas to thesouthern tip of the peninsula.This triangular plateau is atits widest in the north. TheVindhya range and its easternextension namely MahadevHills, Kaimur Hills andMaikal Range are its northernedge. Towards the west, theplateau has a steep slopewhich is considered to be theresult of faulting. This steepslope forms the WesternGhats which extends at mostcontinuously up to the end ofthe peninsula nearKanyakumari over a distanceof 1280 km. The WesternGhats are known by differentregional names such as theSahyadris in Maharashtraand Karnataka, the Nilgiris inTamil Nadu, and Annamalaiand the Cardamom hillsalong the Kerala and TamilNadu border. The elevation ofthe Ghats increases towardsthe south. The highest peak,Anamudi (2,695 m) is inKerala. The most importantgap in the Western Ghats isthe Palghat gap which linksTamil Nadu with Kerala. TheDeccan plateau is the highestalong its western edge andgently slopes towards by Bay

of Bengal in the east. Theeastern edge of the Deccanplateau is marked by a seriesof scattered hills known as theEastern Ghats. These hills risesteeply from the Coromandalcoastal plain. The EasternGhats are well developed inthe region between theGodavari and Mahanadirivers. The Eastern Ghats andWestern Ghats converge inthe Nilgiri hills. Dodda Betta(2,637 m) is the highest peakin the Nilgiri hills.The surface of the Deccanplateau slopes graduallytowards the east. While all themajor rivers of the peninsularblock flow into the Bay ofBengal. Narmada and Taptiare the only two riversflowing in the oppositedirection to fall in the ArabianSea. The northwestern part ofthe Deccan plateau inMaharashtra consists of anextensive lava plateauknown as the deccan trapregion. This consists of flattopped hill ranges forming ontheir flanks series of terraces.

6. The Desert DevelopmentProgramme (DDP) wasstarted in 1977-78 with theobjective of controllingdesertification, restoring

ecological balance andcreating conditions toimprove the economic level ofpeople in desert areas. Theseobjectives are sought to beachieved through activitiessuch as: (1) afforestation withspecial emphasis on shelter-belt plantation, grasslanddevelopment and ,sand dunestabilisation; (2) developmentand productive use of waterresources; and (3) const-ruction of water harvestingstructures and developmentof agriculture and horti-culture etc. It covers both hotand cold desert areas:Gujarat, Haryana andRajasthan (hot deserts) andHimachal Pradesh and J&K(cold deserts).

7. Mangroves are salt tolerentforest ecosystem foundmainly in tropical andsubtropical inter-tidal regionof the worls. They arereservoires of a large numberof plant and animal speciesassociated together over along revolution period andexhibitery remarkablecapacity of salt tolerance.They stabilise the shorelineand act as bulwark againstencroachment by the sea.

Mangroves cover area of4,482 sq.km (0.14% of totalgeographical area)

8. Materials which are resistantto heat at high temperatures(1500° C) are called refract-ories. They are used formaking firebricks which linethe walls of high heatfurnaces. Refractory mineralsinclude fireclays, magnesite,graphite and aluminiumsilicates such as sillimaniteand kyanite.Magnesite occurs in TamilNadu, Karnataka, AndhraPradesh and Rajasthan.Fireclays are found inMadhya Pradesh, WestBengal, Bihar, Karnataka andAndhra Pradesh. Magnesiteis used in blast furnaces andother industrial furnaces andalso for producing liquidcarbon dioxide. Sillimanitewhich occurs in Meghalaya,Madhya Pradesh, Mahara-shtra, Kerala, Tamil Naduand Bihar is used for glasstank furnaces, where hightemperatures are developedand also in electric furnaces

because of its strength andlow electrical conductivity.Kyanite found in Bihar,Andhra Pradesh, Karnataka,Orissa, Rajasthan andMaharashtra is used forlining copper smeltingfurnaces. Graphite, scarce inIndia, is found in AndhraPradesh, Kerala, Bihar,Karnataka and Orissa and isused in foundries, graphitecrucibles and lead pencils.

9. Gypsum is a hydratedsulphide of calcium (CaSO4.2H2O). It occurs in massivelumps or transparent platesin sedimentary rockformations. Over 90 per centof the gypsum reserves ofIndia are found in Rajasthanmainly in the westerndistricts of Bikaner,Ganganagar, Bharatpur,Churu, Jaisalmer, Banner, Paliand Jodhpur. Other stateswhich have gypsum reservesare Jammu and Kashmir,Gujarat, Tamil Nadu, AndhraPradesh, Maharashtra,Himachal Pradesh and UttarPradesh. High quality

gypsum is used in themanufacture of ammoniumsulphate fertiliser. The cementindustry also uses gypsumbut of lesser purity than thatrequired for fertiliser industry.Other uses of gypsum are inagriculture where it is used assurface plaster for conservingmoisture in soil and for helpingin the process of nitrogenabsorption. It is also used formaking plaster of Paris, partitionblock sheets, insulating boardsetc.

10. The eco-system of the WesternGhats is specially suited forthe preservation of bio-diversity. With altitudesvarying from 900 to 1100metres they form a continuousbarrier of rugged topographywith heavy monsoon rainfall.The vegetation is generallyforested and changes fromevergreen to deciduous with agreat variety of trees andplants.The Ghats south of thePalghat gap are the mostcomplex mountain ranges ofthe peninsula. The southerncomplex includes Nilgiris,Anamalais and PalaniCardamom hills. The shola-grasslands in this complexhave existed for a very longperiod. This eco-system haspreserved fragmented forestslike the sholas surrounded bygrasslands (or Savannah).Large animals like sambharand birds move from shola toshola, whereas smalleranimals remain in a shola.The Western Ghats aretherefore able to sustain animmense variety of fauna andflora in the evergreen forestsand the semi evergreen forestson the lower slopes.

11. India generally faces two broadcategories of environmentalproblems (a) problemsassociated with the process ofdevelopment and (b) problemswhich arise from theconditions of poverty andunderdevelopment. Thecountry lacks financialresources for rapid develo-pment and the latest advancedtechnologies are therefore noteasily available to us. In ourefforts to improve our economicconditions as quickly aspossible, we are forced toadopt projects which are poorlyplanned. Schemes which donot incorporate the latestenvironmental protectiontechnologies are implementedin order to get the benefits ofdevelopment eg: PowerHouses without electrostaticprecipitators to arrestdischarges of smoke and ash,chemical factories withoutaffluent treatment plants etc.The other group ofenvironmental problemssprings from poverty and lowstandards of living. Pollutionof rivers by human actions areall too common due to the lackof awareness of the people.As the poor have hardly anyresources, they degradenatural resources.

12. 1. Singrauli is in UttarPradesh and is the site ofthe super-thermal powerstation established by theNational Thermal PowerCorporation (NTPC) witha capacity of 2000 MW.

2. Jaykaynagar in WestBengal is the place wherethe first unit to producealuminium from indige-nous bauxite was establi-shed in 1942.

3. Rishra is in West Bengalnear Calcutta. It is the sitewhere India’s first jute millwas established in 1854.

4. Bokaro in Jharkhand issituated near the Jhariaand Ranigunj coal fields.A modern integrated steelplant with collaborationof the former Soviet Unionwas established here inthe public sector with anultimate capacity of 10million tonnes.

13. “Sponge iron” is directlyreduced iron made byconverting iron ore directly toiron with non-coking coal ornatural gas. The normal ironmaking in integrated steelplants is by melting iron orewith coke and limestone. Thecoke is produced from cokingcoal which is scarce.Limestone serves to removethe impurities. “Sponge iron”is used as alternate orsupplement to scrap iron forproducing steel in mini-steelplants with electric furnaces.The most important projectfor making “sponge iron” islocated at Kothagudam inAndhra Pradesh with a finalcapacity of 60,000 tonnes perannum. Other plants havebeen set up in Orissa andMaharashtra.

14 Rift valleys are steep-sideddepressions on the earth’ssurface resulting fromgeological faults due tofracturing of the surface.Narmada valley is a rift valleyin India.

15. The Hazira-Bijaipur-Jagdis-hpur (HBJ) pipeline transportsnatural gas from Gujarat’s off-shore oilfields to Uttar Pradesh.It benefits industries in

Maharashtra, Gujarat, Mad-hya Pradesh and Uttar Pradesh.

16. Kandla is a tidal portsuffering from heavy siltationrequiring frequent dredging.It has also inadequate linearservices to various countries.Hence it is not fully utilised.

17. The Ganga Waterway fromHaldia to Allahabad is India’sNational Waterway No. 1.

18. It is a broad plain formed bydark silt and salt encrustationson the sea that once surroundedthe Kutch peninsula when itwas an island.

19. The volcanic lava of theDeccan peninsula filled upthe pre-existing topographyabout one million years ago.It is the Deccan trap occurs inparts of Maharashtra,Saurashtra, and MadhyaPradesh.

20. The Arabian Sea branch isSpectacular, because-(1) the Arabian Sea is larger(2) the entire Arabian Seabranch reaches India whilethe Bay of Bengal branchdivides into Myanmar,Malaysia and Thailand also.

21. Minerals which are useful forgenerating energy are called fuelminerals. Such mineralsinclude coal, petroleum, lignite,uranium, thorium etc.

22. Multipurpose river projectsare projects that aim to benefitour population and society inmore than one way. Theobjectives are (1) extension ofirrigation facilities byconstructing dams (2) powergeneration (3) flood controland making river navigable.Some of the majormultipurpose projects areDamodar Valley Project,Bhakra Nangal etc.
