MONEY AND CREDIT
NCERT TEXTBOOK QUESTIONS
Q 1. In Situations with high risks, Credit might create further problems for the Borrower. Explain.
Ans. In situations with high risks, credit might create further problems for the borrower. This is also known as a debt-trap. Taking credit involves an interest rate on the loan and if this is not paid back, then the borrower is forced to give up his collateral or asset used as the guarantee, to the lender. If a farmer takes a loan for crop production and the crop fails, loan payment becomes impossible. To repay the loan the farmer may sell a part of his land making the situation worse than before. Thus, in situations with high risks, if the risks affect a borrower badly, then he ends up losing more than he would have without the loan.

Q 2. How does money solve the problem of Double Coincidence of wants? Explain with an example of your own.
Ans. In a barter system where goods are directly exchanged without the use of money, double coincidence of wants is an essential feature. By serving as a medium of exchanges, money removes the need for double coincidence of wants and the difficulties associated with the barter system. For example, it is no longer necessary for the farmer to look for a book publisher who will buy his cereals at the same time sell him books. All he has to do is find a buyer for his cereals. If he has exchanged his cereals for money, he can purchase any goods or service which he needs. This is because money acts as a medium of exchange. 

Q 3. How do Banks Mediate between those who have surplus money and those who need money?
Ans. Banks keep small portion deposits as cash (15%) for themselves (to pay the depositors on demand). They use the major portion of the deposits to extend loans to those who need money. In this way banks mediate between those who have surplus money and those who need money.

Q 4. Look at a 10 Rupee note. What is written on top? Can you explain this statement?
Ans.Reserve Bank of India” and “Guaranteed by the Government” are written on top.
In India, Reserve Bank of India issues currency notes on behalf of the central government. The statement means that the currency is authorized or guaranteed by the Central Government. That is, Indian law legalizes the use of rupee as a medium of payment that cannot be refused in setting transaction in India. 

Q 5. Why do we need to expand formal sources of credit in India?
Ans. We need to expand formal sources of credit in India due to:
·         To reduce dependence on informal sources of credit because the latter charge high interest rates and do not benefit the borrower much.
·         Cheap and affordable credit is essential for country’s development.
·         Banks and co-operatives should increase their lending particularly in rural areas.

Q 6. What is the basic idea behind the SHGs for the poor? Explain in your own words.
Ans. The basic behind the SHGs is to provide a financial resource for the poor through organizing the rural poor especially women, into small Self Help Groups.
They also provide timely loans at a responsible interest rate without collateral.
Thus, the main objectives of the SHGs are:
·         To organize rural poor especially women into small Self Help Groups.
·         To collect savings of their members.
·         To provide loans without collateral.
·         To provide timely loans for a variety of purposes.
·         To provide loans at responsible rate of interest and easy terms.
·         Provide platform to discuss and act on a variety of social issues such education, health, nutrition, domestic violence etc. 

Q 7. What are the reasons why the Banks might not be willing to lend to certain borrowers?
Ans. The banks might not be willing to lend certain borrowers due to the following reasons:
·         Banks require Proper Documents and Collateral as security against loans. Some persons fail to meet these requirements.
·         The borrowers who have not repaid previous loans, the banks might not be willing to lend them further.
·         The banks might not be willing to lend those entrepreneurs who are going to invest in the business with high risks.
·         One of the principle objectives of a bank is to earn more profits after meeting a number of expenses. For this purpose it has to adopt judicious loan and investment policies which ensure fair and stable return on the funds. 

Q 8. In what ways does the Reserve Bank of India supervise the functions of Banks? Why is this necessary
Ans. The Reserve Bank of India supervises the functions of banks in a number of ways:
·         The commercial banks are required to hold part of their cash reserves with their RBI. RBI ensures that the banks maintain a minimum cash balance out of the deposits they receive.
·         RBI observes that the banks give loans not just to profit making businesses and traders but also to small cultivators, small scale industries, small borrowers etc.
·         The commercial banks have to submit information to the RBI on how much they are lending, to whom, at what interest rate, etc.
·         This is necessary to ensure equality in the economy of the country and protect especially small depositors, farmers, small scale industries, small borrowers etc.
·         In this process RBI also acts as the lender of the last resort to the banks.

Q 9. Analyse the role of credit for development.
Ans. Cheap and affordable credit plays a crucial role for the country’s development. There is a huge demand for loans for various economic activities. The credit helps people to meet the ongoing expenses of production and thereby develop their business. Many people could then borrow for a variety of different needs. They could grow crops, do business, set up industries etc. In this way credit plays a vital role in the development of a country. 

Q 10. MANAV needs a loan to set up a small business. On what basis will MANAV decide whether to borrow from the bank or the moneylender? Discuss.
Ans. MANAV will decide whether to borrow from the bank or the money lender on the basis of the following terms of credit:
v  Rate of interest
v  Requirements availability of collateral and documentation required by banker.
v  Mode of repayment.
v  Depending on these factors and of course, easier terms of repayment, MANAV has to decide whether he has to borrow from the bank or the moneylender

Q 11. In India, about 80 per cent of farmers are small farmers, who need credit for cultivation.
(a) Why might banks be unwilling to lend to small farmers?
(b) What are the other sources from which the small farmers can borrow?
(c) Explain with an example how the terms of credit can be unfavorable for the small farmer.

(d) Suggest some ways by which small farmers can get cheap credit.
Ans. (a) Bank loans require proper documents and collateral as security against loans. But most of the times the small farmers lack in providing such documents and collateral. Besides, at times they even fail to repay the loan in time because of the uncertainty of the crop. So, banks might be unwilling to lend to small farmers.
(b) Apart from bank, the small farmers can borrow from local money lenders, agricultural traders, big      landlords, cooperatives, SHGs etc.
(c) The terms of credit can be unfavourable for the small farmer which can be explained by the following -
Ramu, a small farmer borrows from a local moneylender at a high rate of interest i.e. 3 per cent to grow rice. But the   crop is hit by drought and it fails. As a result Ramu has to sell a part of land to repay the loan. Now his condition becomes worse than before.
(d) The small farmers can get cheap credit from the different sources like – Banks, Agricultural Cooperatives, and        SHGs.

Q 12. Fill in the blanks:

(i) Majority of the credit needs of the __POOR_. Households are met from informal sources.
(ii) __HIGH__costs of borrowing increase the debt-burden.
(iii) ____RBI___issues currency notes on behalf of the Central Government.
(iv) Banks charge a higher interest rate on loans than what they offer on ___DEPOSITS___
(v) __COLLATERAL_is an asset that the borrower owns and uses as a guarantee until the loan is repaid to the lender.

Q 13. Choose the Most appropriate answer.
(i) In a SHG most of the decisions regarding savings and loan activities are taken by

(a) Bank.
(b) Members.
(c) Non-government organisation.
► (b) Members.
(ii) Formal sources of credit does not include
(a) Banks.
(b) Cooperatives.
(c) Employers.
(c) Employers.

Q.14 . What are Demand Deposits? Describe any three salient features of demand deposits.
Ans. People with surplus money or extra amount deposit it in banks. The banks keep the money safe
And give an interest on it. The deposits can be drawn at any time on demand by the depositors.
That is why they are called 'demand deposits'.
(i) The demand deposits encash able by issuing cheques have the essential features of money.
(ii) They make it possible to directly settle payments without the use of cash.
(iii) Since demand drafts/cheques are widely accepted as a means of payment along with Currency, they constitute money in the modern economy

Q.15. Explain any two features each of Formal Sector Loans and Informal Sector Loans?
Ans. Formal Sector Loans:
Formal sector loans include loans from banks and cooperatives.
Features of formal sector Loans are:
(i) Formal sectors provide cheap and affordable loans and their rate of interest is monitored by RBI.
(ii) Formal sector strictly follows the terms of credit which includes interest rate, collateral, Documentation and the mode of repayment.

Informal Sector Loans:
Informal sector loans include loans from moneylenders, traders, employers, relatives, and friends
etc. Features for informal sector loans are:
(i) Their credit activities are not governed by any organisation, therefore they charge higher Rate of interest.
(ii) Informal sector loan providers know the borrowers personally, and hence they provide Loans on easy terms     without collateral and documentation

MINERALS AND ENERGY RESOURCES SUMMARY



Department of Social Science
MINERALS AND ENERGY RESOURCES
GEOGRAPHY(X)
Chapter 04



MINERALS
A homogeneous, naturally occurring substance with definable internal structure is called mineral.

MINING-
 Economic activity of extraction of minerals from below the earth’s surface is called Mining.

Use of Minerals in Daily Life
·         Materials of daily use are made of minerals like tooth Paste Contains Silica, Limestone, Phosphate, etc.
·         They are also needed by our body(0.3%).
·         They are basis of all economic Activities.
·         They are also studied to know the formation, age, and composition of the earth.

MODE OF OCCURRENCE OF MINERALS:
Minerals are usually found in Ores. An Ore is a naturally occurring meterial having one or more Minerals in sufficient concentration mixed with other elements.
Minerals Generally occur in these forms:
  1. In Igneous and Metamorphic rocks: The smaller occurrences are called veins and the larger occurrences are called lodes. They are usually formed when minerals in liquid/molten and gaseous forms are forced upwards through cavities towards the earth’s surface. Examples: tin, copper, zinc, lead, etc.
  2. In Sedimentary rocks: In these rocks, minerals occur in beds or layers. Coal, iron ore, gypsum, potash salt and sodium salt are the minerals found in sedimentary rocks.
  3. By Decomposition of surface rocks: Decomposition of surface rocks and removal of soluble constituents leaves a residual mass of weathered material which contains ores. Bauxite is formed in this way.
  4. As Alluvial deposits: These minerals are found in sands of valley floors and the base of hills. These deposits are called placer deposits. They generally contain those minerals which are not corroded by water. Examples; gold, silver, tin, platinum, etc.
  5. In Ocean Water: Most of the minerals in ocean water are too widely diffused to be of economic importance. But common salt, magnesium and bromine are mainly derived from ocean waters.
DISTRIBUTION OF MINERALS IN INDIA
India is fortunate to have fairly rich and varied Mineral Resources, but these resources are unevenly distributed;
Ø  Peninsular Plateau: Peninsular Rocks contain Most of the reserve of Coal, Metallic Minerals,Mica,Non Ferrous minerals and Non Metallic Minerals
Ø  Gujarat and Assam: Sedimentary rocks in Gujarat and Assam have Most of Petroleum Deposits.
Ø  Rajastan: It has Reserve of many Non Ferrous Minerals.
Ø  Northern Plains: There is very little or No economic Minerals in vast Alluvial Plains of North India.
Most of the Minerals in India are Nationalized and their mining is only possible only after obtaining due permission from Government.
But in most of the tribal areas of North East India Minerals are owned by Individuals or Communities.
In Meghalaya There are large deposits of Coal, Iron Ore, Limestone…etc Coal Mining In Jowai and Cherapunjee is done by family members in the form of a Long Narrow tunnel, Known as RAT HOLE MINING.

CLASSIFICATION OF MINERALS
  1. Metallic
    1. Ferrous (containing iron): Iron ore, manganese, nickel, cobalt, etc.
    2. Non-ferrous: Copper, lead, tin, bauxite, etc.
    3. Precious: Gold, silver, platinum, etc.
  2. Non-metallic: Mica, salt, potash, sulphur, granite, limestone, marble, sandstone, etc.
  3. Energy Minerals: Coal, petroleum and natural gas

METALLIC MINERALS.
Minerals containing metals are called metallic minerals. Like Gold,Silver,Tungsten,etc
1)      FERROUS MINERALS
Minerals having Iron Content Are called ferrous Minerals. India Exports fairly large amount of ferrous minerals. These minerals provide a strong base for the development of metallurgical Industries.

IRON ORE
Iron ore is the basic mineral and the backbone of industrial development.India is rich in good quality iron ores. Magnetite is the finest iron ore with a very high content of iron upto 70%. This iron ore is valuable for the electrical industry because of its excellent magnetic properties. Hematite ore is the most important industrial iron ore; in terms of usage. The iron content of hematite is 50-60%.
Major Iron Ore Belts in India
  • Orissa Jharkhand Belt: Badampahar mines in the Mayurbhanj and Kendujhar districts of Orissa have high grade hematite ore. Additionally, hematite iron ore is mined in Gua and Noamundi in Singhbhum district of Jharkhand.
  • Durg Bastar Chandrapur Belt: This belt lies in Chhattisgarh and Maharashtra. The Bailadila range of hills in the Bastar district of Chhattisgarh have very high grade hematite ore. This hilly range has 14 deposits of super high grade hematite ore. Iron from these mines is exported to Japan and South Korea via Vishakapatnam port.
  • Bellary Chitradurga Chikmaglur Tumkur Belt: This belt lies in Karnataka. The Kudremukh mines located in the Western Ghats are a 100 percent export unit. The ore from these mines is transported as slurry through a pipeline to a port near Mangalore.


  • Maharashtra Goa Belt: This belt inculdes the state of Goa and Ratnagiri district of Maharashtra. The ores in these mines are not of very high quality. They are exported through Marmagao port.
MANGANESE
Manganese is mainly used in the Manufacturing of Steel and ferro-manganese alloy. It is also used in making Bleaching powder, Insecticides and Paints. Nearly 10 kg of Manganese is required to manufacture One tonne of Steel. India Ranks fifth in the World in the production of manganese. Madhya Pradesh( 27%)  is the largest Producer of Manganese Ores in India.
Maharshtra 25%    Odisha 25%   Karnataka 11%    Andra Pradesh   10%      ( Based on 2016-2017 Data)
2)      NON FERROUS MINRALS
India’s Reserves and Production of on ferrous minerals is not very satisfactory. Minerals that do not contain Iron content are called non-ferrous minerals. India has only a few reserve of nonferrous minerals. These minerals provide strong base for Metallurgical industry, engineering industry and electrical industry. E.g Copper,Lead,Zinc,Bauxite,gold etc.

COPPER
India is Critically Deficient in the Reserve and Production of Copper.Copper is mainly used in Electrical cables, Electronics and Chemical industries. Leading producer Khetri mines in Rajastan.The Balaghat mines in M P . Madhya Pradesh produce 52% of India’s copper. Rajasthan is the next leading producer with about 48% share( 2010-11 Data) . Copper is also produced in the Singhbhum district of Jharkhand.

BAUXITE/ ALUMINIUM
Bauxite ore is used for obtaining Aluminium that is formed by Decomposition of rocks rich in aluminium silicates. Bauxite is a clay like substance from which Alumia extract firstly and later alumina become aluminium. Aluminium is lightweight and Strong and hence is used in a variety of applications includes Utensils,Pots,Aircrafts Electrical goods. Aluminium is an important metal because it combines the strength of Metals such as Iron with extreme lightness and also with good conductivity and great Malleability (Quality of something that can be shaped into something else without breaking). Amarkantak plateau, Maikal hills and the plateau region of Bilaspur-Katni are the main areas of bauxite deposits. Odisha is the leading producer of bauxite in India. Panchpatmali in Koraput district is the most important centre of bauxite deposit in Odisha.Oddisha is the largest Producer of Bauxite in India (49%)
Gujarat 24%      Jharkhand   9%      Chhattisgarh    8%     Maharashtra   8 %     (Based on 2016-17 Data)

NON METALIC MINERALS.
The basic characteristic of non –metallic minerals is that they do not yield new products on melting. Mica and limestone are the important non-metallic minerals.
MICA
Mica is a mineral which is made up of a series of Plates or Leaves. The mica sheets can be so thin that a thousand of them can be layered into a few centimetre thick mica sheet. Mica has excellent Di-electric strength, Low Power loss factor, Insulating properties and Resistance to high voltage. Mica is widely used in Electric and Electronic industries.
Mica can be Clear, Black, Green, Red, Yellow or Brown.
Mica deposits are found in the Northern edge of the Chotta Nagpur plateau. Koderma-Gaya-Hazaribagh belt of Jharkhand is the leading producer of mica. Ajmer in Rajasthan and Nellore in Andhra Pradesh are the other important producers of mica.

LMESTONE
Limestone is found in association with rocks composed of calcium carbonates or calcium
And magnesium carbonates. It is found in Sedimentary rocks of most geological
Formations. Limestone is the basic raw material for the Cement Industry and essential for smelting iron ore in the    blast furnace. Rajasthan is the Largest Producer of Limestone ( 21%).
Madhya Pradesh & AP 11%    Chhattisgarh 10%   Karnataka 10%            (Based on 2016-2017 Data)

HAZARDS OF MINING (Known as Killer Industry)
Mining is a Hazardous Industry; both for the workers and for the residents. The Miners have to work under tough conditions where No natural light is available. There is always a Risk of Collapse of mine roof, inundation with water and fire. The areas around mines face the problem of Too much Dust from the mines. Slurry from mines damages the roads and the farmland. Houses and clothes become Dirty more often than in other areas. Miners are at great risk of getting afflicted with Pulmonary disorders. Cases of Respiratory tract diseases are very high in mining areas.

CONSERVATION OF MINERALS
It takes millions of years for the formation of minerals. Compared to the present rate of consumption, the replenishment rate of minerals is very slow. Hence, mineral resources are finite and non-renewable. Due to this, it is important that we conserve the mineral resources.
ENERGY RESOURCES
1)      CONVENTIONAL ENERGY RESOURCES: These Resources have been used for a long time they take Millions of years to form again. They are Finite and non-renewable Firewood, cattle dung cake, coal, petroleum, natural gas and electricity.
2)      NON-CONVENTIONAL ENERGY RESOURCES:  These Energy have come into use recently. These are freely available and renewable. Solar, Wind, Tidal, Geothermal, Biogas and Atomic energy.

CONVENTIONAL ENERGY RESOURCES

FIREWOOD AND CATTLE DUNG CAKE: 
As per estimates, more than 70% of energy need in rural households is met by firewood and cattle dung cake. A decreasing forest area is making it difficult to use firewood. Dung cake can be put to better use in the form of manure and hence its use should also be discouraged.

COAL:
India is highly dependent on coal for meeting its commercial energy requirements. Depending on the degree of compression during its formation, there are varieties of coal.
  1. Lignite: It is a low grade brown coal. It is soft and has high moisture content. Neyveli in Tamil Nadu has the main reserves of lignite coal. This type of coal is used for electricity generation.
  2. Peat: It has a low carbon content and low heating capacity and high moisture content.
  3. Bituminous coal: Coal which was formed because of increased temperature and was buried very deep is called bituminous coal. This is the most popular coal for commercial use. High grade bituminous coal is ideal for use in metallurgy.
  4. Anthracite coal: This is the highest quality hard coal.
In India, coal occurs in rock series of two main Geological ages. The Gondwana coal was formed over 200 Million years ago.
The tertiary deposits are about 55 million years old. The major sources of Gondwana coal are located in the Damodar valley (West Bengal-Jharkhan). In this belt; Jharia, Raniganj and Bokaro are important coalfields. Coal deposits are also present in the Godavari, Mahanadi, Son and Wardha valleys.
Tertiary coal is found in the north-eastern states of Meghalaya, Assam, Arunachal Pradesh and Nagaland.

PETROLEUM
Petroleum is also known as Mineral Oil and Liquid Gold. After coal, the next major energy resource in India is petroleum. Petroleum is a major source of fuel for various uses. Petroleum also provides raw materials for various manufacturing industries; like plastic, textiles, pharmaceuticals, etc.
Most of the petroleum in India occurs in anticlines and fault traps in the rock formations of the tertiary age. The oil bearing layer is a porous limestone or sandstone through which oil may flow. The intervening non-porous layers prevent the oil from rising or sinking. Petroleum is also found in fault traps between porous and non-porous rocks. Gas usually occurs above the oil because it is lighter than oil.
Mumbai High produces about 63% of India’s petroleum, Gujarat produces 18% and Assam 16%. Ankeleshwar is the most important oil field in Gujarat. Assam is the oldest oil producing state of India –(1867 First Oil Field Discovered in Assam). Important oil fields of Assam are Digboi, Naharkatiya and Moran-Hugrijan.

NATURAL GAS
Natural gas is found along with or without petroleum. It is used as fuel and also as industrial raw material. Large reserves of natural gas have been discovered in the Krishna-Godavari Basin. Gulf of Cambay, Mumbai High and Andaman Nicobar islands are also important areas with large reserves of natural gas.
The 1700 km long Hazira-Vijaipur-Jagdishpur pipeline links Mumbai High and Bassein with the fertiliser, power and industrial complexes in western and northern India. Natural gas is mainly used by the fertiliser and power industries. Now-a-days, use of CNG (Compressed Natural Gas) is increasing as vehicle fuel in the country.

ELECTRICITY
Electricity is generated mainly by two methods; by running water which drives hydro turbines and by burning other fuels like coal, petroleum and natural gas to drive turbines. Bhakra Nangal, Damodar Valley Corporation, Kopili Hydel Project, etc. are major hydroelectric producers in the country. At present, there are over 300 thermal power stations in India.

NON-CONVENTIONAL SOURCES OF ENERGY
NUCLEAR ENERGY:
 Nuclear energy is obtained by altering the structure of atom. When the structure of an atom is altered, too much energy is released in the form of heat. This heat is utilised to generate electric power. Uranium and Thorium are used for generating atomic power. These minerals are available in Jharkhand and the Aravalli ranges of Rajasthan. The Monazite sand of Kerala is also rich in Thorium.

SOLAR ENERGY:
Photovoltaic technology is used to convert solar energy into electricity. The largest solar plant of India is located at Madhapur near Bhuj. Solar energy holds great promises for the future. It can help in minimizing the dependence on firewood and animal dung cakes in rural areas. This will also help in conservation of fossil fuels.

WIND POWER: 
India now ranks as a “Wind Super Power” in the world. The wind farm cluster in Tamil Nadu (from Nagarcoil to Madurai) is the largest cluster in India. Andhra Pradesh, Karnataka, Gujarat, Kerala, Maharashtra and Lakshadweep are also important centres of wind power production.

BIOGAS: 
Biogas can be produced from shrubs, farm waste, and animal and human waste. Biogas is more efficient than kerosene, dung cake and charcoal. Biogas plants can be set up at municipal, cooperative and individual levels. The gobar gas plants provide energy and also manure.

TIDAL ENERGY:
 Floodgate dams are built across inlets. The water flows into the inlet during high tide and gets trapped when the gate is closed. Once the tide recedes, the gates are opened so that water can flow back to the sea. The flow of water is used to run the turbine to generate electricity. A 900 MW tidal energy power plant is set up by the National Hydropower Corporation in the Gulf of Kuchchh.

GEO THERMAL ENERGY:
 We know that the inside of the earth is very hot. At some places, this heat is released on the surface through fissures. Groundwater in such areas becomes hot and rises up in the form of steam. This steam is used to drive turbines. Two experimental projects have been set up in India to harness geothermal energy. They are; the Parvati valley near Manikarn in Himachal Pradesh and the Puga Valley in Ladakh.

  CONSERVATION OF RESOURCES
  In order to conserve energy, we must —
·         Use the public transport system more frequently.
·         Switch off electricity whenever not required.
·         Use power-saving devices.
·         Check the power equipment’s regularly.
·         Use non-conventional sources of energy more frequently.
·         After all “Energy saved is Energy Produced”
