Question 5.
What is the difference between the system of reservation of Constitu¬encies and the system of separate elecorate? Why did the Constitution makers reject the latter?
Answer:
To ensure adequate representation to certain weaker social groups, the constitution maker wanted to introduce some mechanism, like separate electorde system which was introduced by British Government in Govt, of India Act 1909, 1919, and 1935. Separate electorate system means that for electing a representative from a particular community only those voters would be eligible who belong to that community.

The constitution makers however rejected this proposal because of the fear that this system will divide the society and they decided to adopt the system of reservation by which certain number of seats were reserved for the weaker social groups like Scheduled Castes and Scheduled Tribes.

This provision was made initally for ten years and now it has been extended upto 2010. Today out of 543 elected seats in Lok Sabha, 79 seats are reserved for scheduled castes and 41 seats are reserved for the Scheduled Tribes.

b. Election Commission does not supervise Panchayat and Muncipal Elections.
c. President of India cannot remove an election commission.
d. Appointment of more than one Election Commissioners in the Election Commission is mandatory.
Following two questions are incorrect

(a) FPTP system is followed for all the elections in India Correct version is that FPTP is not followed for all the elections in India. For the election of President, Vice President and members of Rajya Sabha, Proportional Representation method of election is used.

(c) President of India cannot remove an Election Commissioner The correct position is that President of India can remove Election Commissioner if charges of corruption are proved against him.

Question 7.
Indian electrol system aims at ensuring representation of socially disadvantaged sections. However we are yet to have even 10 percent women members in our legislatures. What measures you would suggest to improve the situation?
Answer:
Constitution has ensured adequate representation of various weaker social groups like Scheduled Castes and Scheduled Tribes by way of reservation but it is a fact that even 10 percent woman do not find representation in Parliament and State Assemblies because of socio-economic reasons.

No reservation has been made for them in the seats in Parliament and State Assemblies. However by 73rd and 74th Constitutional amendments, one third of the total seats are reserved for women in membership and presidents of the local rural and urban bodies ‘respectively.

Socio, economic improvement of women can be one method of women participation in the democratic institutions like Parliament and State Assemblies. Reservation of seats is another method for which various Constitutional amdendment bill have been brought but could not become Act because of political reasons. There is urgent need of political concensus in the mode of giving reservation to women so that woman also could get adequate representation in democratic institutions.

Question 8.

c. There should not be discrepancy between votes and seats for the different parties.
d. People should be able to elect a good candidate even if they do not like his or her political party.
Answer:
a. As per the wishes of the people given in a part the FPTP method of election will suit them because in fair system people have right to choose their representative of their choice who will be responsible and accountable to them and who can be removed in the next election.

NCERT Solutions for Class 11 Political Science Chapter 3 Election and Representation

b. To give fair representation to the people of several linguistic groups, method of propotional representation will be most suitable which ensures the representation of every such minority groups in proportion to their population strength.

c. To satisfy the wishes of the people of ‘c’ section. List system of proportional method of representation can be used which ensures the rational relationship between the votes and seats for the political parties.

d. People of the wishes of sec’d1 need FPTP system in which they-can vote to candidate even if they do not like his or her political party.

Question 9.
A former chief election commissioner joined a political party and contested the elections. There are various views on this issue. One view is that a former Election Commissioner is an independent citizen and has a fight to join any political party and to contest election. According fo other view, leaving this possibilty open, can affect the impartiality of the Election Commissions. So former Election Commssioners must not be allowed to contest any* election. Which position do you agree with and why?
Answer:
It is a fact that one Chief Election Commissioner joined a political party and contested the election also. It is also true that Election Commissioner is also a citizen of India and therefore has right to vote and join any political party and so can think of contesting the election but since he has been on the top position of the body which conducts and controls the election, the propriety demands that they should not contest the election otherwise the charge of influcing the process will not be ruled out.

As we expect that there should ban on the practicing of Judges of the courts after retirement, similarly we can say that Election Commissioner should be a political man after retirement.

Question 10.
“Indian democracy is ready to shift from a trade First Part the Post System to a system of Proportional Representation.” Do you agree with this statement? Give your reasons for or against this statement
Answer:
There is serious discussion about Election reforms in India. One of the area of reform is method of representation. We have adopted for FPTP system or method of representation in which every person is given right to vote a candidate of his choice and, after elections are over the counting of votes takes place.

A person who gets the majority of the total polled votes, is declared alected. However, in some elections like that of President and Vice President and Rajya Sabha elections are conducted on the basis of Proportional Method of Representation is which voters can express their preference for the contesting candidates.

The need to change FPTP system is being felt because of some negative impacts of the present system. The first method is that in this system minority rules over majority. Second negative imfact is that through this method of election, the minority social groups do not find adequate representation.

In this situation the ultimate revolt is of political unhability. There are several arguments against the PR system are given, one argument against is that PRsystem is very complex system, hence it is not suitable for a country like India who has no adequatic literacy percentage. The ultimate solution lies in the continuation of the present system with care and improvement.

To make it representative people of all shades and opinion were gives representation by means of nomination. Constituent Assembly was dominated by Congress which was itself a representative party of all sections of the society.

(b) Constitution making did not involve any major decision since there was general concensus among the leaders at that time about its basic framework. (Incorrect)
Answer:
It is also incorrect because lot of efforts had to be made to achieve concensus on number of controvisal issues. There was no immediate consensus on the basic structure of the constitution.

NCERT Solutions for Class 11th Political Science Chapter 1 Constitution: Why and How?

(b) The constitution has distributed power in such a way as to make it difficult to subvest it.
Answer:
The Constitution has distributed the powers between centre and states as per three lists ie central list consisting 97 subjects, state list consisting 66 subjects and concurrent list with 47 subjects. No one can subvert this system of division of powers because judiciary in there to see that no area of power could be violated by any organ. For this judiciary is given power of Judicial review.

(c) The Constitution is the focus of people’s hopes and aspirations.
Answer:
The Constitution is the focus of people’s hopes because we have a constitutional: government which means the government will have to work as per provisions of the government. Therefore the ruler cannot be arbitrary. The constitution puts a check on the functioning of the government. Con-stitution is an instrument of welfare of the people. It is the embodiment of people’s values and commitments. Therefore it is the last hope of the people.

Question 6.
Why is it necessary for a country to have clear demarcation of powers and responsibilities in the Constitution? What would happen in the absence of such a demarcation?
Answer:
Separation of powers of each organ of the government i.e. Executive, Legislature and Judiciary is very necessary for the safeguard of the liberties and rights of the citizens. It all the powers are vested in one organ, it would lead to authoritarianism and arrogancy which would ultimately restrict and harm the people’s liberties and there will be mis-governance. Now a days most of the democratic governments are working on the basis of separation of powers and responsibilities.

NCERT Solutions for Class 11th Political Science Chapter 1 Constitution: Why and How?

Question 7.
Why is it necessary for a constitution to place limitation on the rulers? Can there be a Constitution that gives no power at all to the citizens?
Answer:
Constitution is the product of doctrine of Constitutionalism which stands for check on the use of powers by the rulers. Constitutionalism stands for rule by Constitutional Law to check the whims and arbitrariness of the rulers. It the rulers are not checked by such constitutional Laws, he or she would be autocratic and people’s rights and liberties will be in danger. There is hardly any Constitution in true sense which does not give any right to the citizens.

Question 8.
The Japanese Constitution was made when the US army is occupation was still in control of Japan after its defeat in the Second World War. The Japanese Constitution could not have had any provision that the US government did not like. Do you see any problem is this way of making the Constitution? In which way was the Indian experience different from this?
Answer:
It is historical fact that when The Japanese Constitution was being written, the US Army was still in control. It is also a fact that the Constitution was being written as per the likings of the US government. Since the people of Japan worshiped the Monarch (Emperor), therefore Monarchy was retained and Parliamentary democracy with Monarch as nominal head was set up.

Indian experience was totally different to that of experience of Japan in this regard. When we adopted our Constitution on 26th Jan. 1950 we were sovereign and independent democracy. Our constitution was written by duly elected, representative and sovereign Constituent Assembly. There was no any kind of control of British Government on our Constitution making process.

Question 9.
Rajat asked his teacher this question “The Constitution is a fifty year old and therefore out dated book. No one took my consent for implementing it. It is written is such a tough language that I cannot understand it. Tell me why should I Qbey this document.” It you were the teacher, how would you answer Rajat?
Answer:
Outbrust of Mr. Rajat in the form of a question to the teacher is childish based on his immaturity and mis- understanding because in fifty years of its working our Constitution has not become outdated, rather, it is in the process of evolution, retaining its’well tested and successful working of the basic features.

If I were a teacher I would have answered to Rajat in the most satisfactory way, I would have told him the meaning and purpose of the Constitution and apprised him of the circumstances and the manner in which the Constitutions was written. I would have made him understood that the language of the Constitution is legal and judiciary is there to explain and interpret it. It is not supposed to be the language of common man. Legitimate government are competent to implement the constitution.

Question 10.
In a discussion on the experience of the working of our Constitution, three speakers took three different positions.
Answer:
(a) Harbans: The Indian Constitution has succeeded in giving us a framework of democratic government
(b) Neha
The Constitution made solemn promises of ensuring liberty, equality and fraternity. Since this has not happened, the Constitution has failed.
(c) Nazima :-The Constitution has not failed us. We have failed the constitution.

NCERT Solutions for Class 11th Political Science Chapter 1 Constitution: Why and How?

Do you agree with any of these positions? If yes, why? It not, what is your own position?
Answer:
I fully agree with Mr. Harbans that’ Indian Constitution has suc-ceeded in giving us a frame work of democratic government as it is written in the preamble of the Constitution that India will be sovereign, socialistic, secular democratic Republic.

As far as Neha’s position is concerned, it is true that Constitution has ensured in its preamble the justice equality, liberty and fraternity and has also provided mechanism of achieving them in the form of Fundamental Rights, Directive Principles of policy and provision of Adult franchise and also existence of independent Judiciary. Neha is wrong when she says that Constitution has failed. In fact inspite of the fact that we have not been able to build a complete equalitarian society, we cannot say that our Constitution has failed.

As a matter of fact Nazima seems to be right that the Constitution has not failed us but we have failed the Constitution. We lack in National Character. We have to learn a lot to be a good citizen. Ultimately the conclusion is that our Constitution is a perfect document having the values, philosophy and institutions suiting our ethos and goal and has the capacities to adjust itself to the changing needs.

NCERT Solutions for Class 11 Geography Chapter 7 Natural Hazards and Disasters

Question 2.
Answer the following questions in less than 30 words :
(i) When can a hazard become a disaster?
Answer:
Hazards and disasters are closely related. Hazard is a threat while disaster is an event. Natural hazards that cause great loss of human life and economy are called disasters and catastrophers while disaster is an extraordinary event of limited duration which causes serious disruption of economy of the country.

(ii) Why are there more earthquakes in the Himalayas and in the north-eastern region of India?
Answer:
The earthquakes in the Himalayan region are tectonic in origin. Because the Indian plate is moving at a speed of one centimetre per year towards the north and north-eastern direction and this movement of plates is being constantly obstructed by the Eurasian plate from the north.

As a result of this, both the plates locked with each other resulting in accumulation of energy at different points of time. Excessive accumulation of energy results in the development of stress which causes breaking up of rocks and sudden release of energy causes earthquakes along the Himalayan arc and north-east.

(iii) What are the basic requirements for the formation of a cyclone?
Answer:
The basic requirements for the formation of a cyclone :

  1. Temperature of the oceanic surface over 26°C.
  2. Appearance of a closed isobar.
  3. Pressure dropping below lOOOmb.
  4. Areas of circular movement, first spreading to a radius of 30-50 km, then increasing gradually to 100-200 km. and even to 1000 km.
  5. Vertically the wind speed first rising to a height of 6 km, then much higher.

NCERT Solutions for Class 11 Geography Chapter 7 Natural Hazards and Disasters

(iv) How are the floods in eastern India different from the ones in western India?
Answer:
Floods occur due to :

  • Excessive rainfall by the south-west monsoon, tropical cyclones in the pre and post monsoon period.
  • Silting of river beds.
  • Deforestation and changes in the river courses.

All factors are favourable in eastern India. Therefore, flood in eastern India is different from the one in western India.

(v) Why are there more droughts in thecentral and western India?
Answer:
The central and western India i.e. Rajasthan, west of Aravali Hills, Kachchh region of Gujarat, Jaisaimer and Barmer receive less than 90 mm. average annual rainfall. So that there are more droughts.

Question 3.
Answer the following questions is not more than 125 words :
Identify the Landslide-prone regions of India and suggest some measures to mitigate the disasters caused by these.
Answer:
Landslide is the rapid sliding of large mass of bedrocks or regolith. On the basis of frequency and eertain casual relationship with the controlling factors like geology, geomorphic agents, slope, landuse, vegetation cover and human activities, India has been divided into the following landslide prone-regions:
(i) Very high Vulnerability Zone-The Himalayas and Andaman and Nicobar, high rainfall regions, north-eastern regions, along with areas that experience frequent ground shading.

(ii) High Vulnerability Zone – All Himalayan stateS Juid states from the north eastern regions except the plains of Assam.

(iii) Moderate to Low Vulnerability Zone – Areas that receive less precipitation such as trans-Himalayan areas of Ladakh and Spiti (Himachal Pradesh). Land-slides due to mining are most common in the states like Jharkhand, Orissa, Chattisgarh, Madhya Pradesh, Maharashtra, Andhra Pradesh, Karnataka, Tamil Nadu, Goa and Kerala.

Measures to mitigate the disaster caused by landslide :

(i) Afforestation – The planting of trees and other vegetation on hill slopes and uncultivated land is helpful in controlling landslides to some extent.

(i) Restricted grazing of animals – Restricted grazing of animals should be practiced in order to minimise the loss of plant cover.

(iii) Terracing – Terracing is cutting the hill slopes in a series of large steps made up of flat fields. Terracing is also effective in checking the landslides.

NCERT Solutions for Class 11 Geography Chapter 7 Natural Hazards and Disasters

Question 4.
What is vulnerability? Divide India into natural disaster vulnerability zones based on droughts and suggest some mitigation measures.
Answer:
Vulnerability – The disasters are sudden and violent, different social groups gets affected and respond to it differently. The difference in their ability to cope up with disasters is known as vulnerability, poor people are more vulnerable than the rich due to their lower tolerance capabilities.

Disasters are the result of harmful attacks brought against human beings by external agents. Drought is shortage of water due to inadequate precipitation and excessive rate of evaporation. Droughts and floods are the two accompanying features of Indian climate, about 30% of country’s total area is identified as drought vulnerized area.

There is large-scale variation and unpredictability in the behaviour of the monsoon in India. On the basis of severity of droughts, India can be divided into the following vulnerability zones:

(i) Extreme Vulnerability Zone – Most parts of Rajasthan,particularly areas to the west of Aravali Hills and Kachchh region of Gujarat, Jaisalmer and Barmer from Indian desert that receive less than 90 mm. average annual rainfall.

(ii) Severe Drought Vulnerability Zone – Parts of eastern Rajasthan, most of Andhra Pradesh and Karnataka Plateau, northern parts of interior Tamil Nadu and southern parts of Jharkhand and interior Orissa.

(iii) Moderate Drought Vulnerability Zone – Northern parts of Rajasthan, Haryana, southern districts of Uttar Pradesh, remaining parts of Gujarat, Maharashtra except Konkan, Jharkhand and Coimbatore plateau of Tamil Nadu.

Mitigation measures
The following steps to be taken for the drought mitigation programme:

  • Provision for the distribution of safe drinking water, medicines for the victims and availability of fodder and water for the cattle.
  • Shifitingofthepeopleandtheirlivestocktosaferplacesneedto be done.
  • Identification of ground water potential, transfer of river water from the surplus to the deficit areas (planning for inter-linking of rivers).
  • Construction of reservoirs and dams.
  • Remotesensingandsateiliteimageriescanbehelpfiilinidentifying the river basin.
  • To provide proper training to practise the drought-resistant crops.

Bhangar represents a system of older alluvium soil, deposited away from the flood plains.

Question 3.
Answer the following questions in not more than 125 words :
(i) What are black soils? Describe their formation and characteristics.
Answer:
The black soil is very deep. These soils are also known as the? ‘Regur Soil’ or the ‘Black Cotton Soil’. The black soils are generally I clayey, deep and impermeable. They swell and become sticky when wet and shrink when dried. So, during the dry season, these soils develop wide cracks.

Thus, there occurs a kind of self ploughing’. Because of this character of slow absorption and loss of moisture, the black soil retains the moisture for a very long time, which helps the crops, especially the rainfed ones, to sustain even during the dry season, Chemically, the black soils are rich in lime, iron, magnesia and alumina. They also contain potash. But they lack in phosphorous, nitrogen and organic matter. The colour ofthe soil ranges from deep black to grey.

(ii) What is soil conservation? Suggest some measures to conserve soil.
Answer:
Soil conservation is a methodology to maintain soil fertility, prevent soil erosion and exhaustion, and improve the degraded condition of the soil

NCERT Solutions for Class 11 Geography Chapter 6 Soils

Soil conservation is necessary. The important measures to conserve soil are as follows :

  • Scientific land use
  • Scientific crop rotation
  • Contour ploughing and bunding
  • Afforestation
  • Construction of barriers against water gullies
  • Increased use of organic manures
  • Replacing flood irrigation

(iii) How do you know that a particular type of soil is fertile or not? Differentiate between naturally determined fertility and culturally induced fertility.
Answer:
Soil Survey of India, established in 1956, made comprehensivestudies of soils in selected areas like in the Damodar Valley. The National Bureau of soil survey and the Land Use Planning, an Institute under the control of the Indian Council of Agricultural Research (ICAR), did a lot of studies of Indian soils.

In their effort to study soil and to make it comparable at the international level, the ICAR has classified the Indian soils on the basis of their nature and character as per the United States Department of Agriculture (USDA) soil taxonomy.

On the basis of genesis, colour, composition and location, the soils of India have been classified into :

  • Alluvial soils
  • Black soils
  • Red and Yellow soils
  • Laterite soils
  • Arid soils
  • Saline soils
  • Peaty soils
  • Forest soils.

Soils were classified on the basis of their inherent characteristics and external features such as texture, colour, slope of land and moisture 1-1 content in the soil. Based on texture, main soil types were identified as sandy, clayey, silty and loam, etc. On the basis of colour, they were red,yellow, black, etc.

Question 3.
Answer the following questions in not more than 150 words :
(i) What steps have been taken up to conserve forests?
Answer:
The conservation of forests is of great importance to the survival and prosperity of humankind. The government of India proposed a nationwide forest conservation policy in 1952 which was further modified in 1988. According to new forest policy the government will emphasize on sustainable forest management in order to conserve and expand forest reserve.
The policy aimed at:

  • Bringing33%of its geographical areas under forest cover, which is 6% more than the area at the national level.
  • To maintain environmental stability and to restore forests.
  • To conserve the natural heritage of the country, its biological diversity and genetic pool.
  • To check soil erosion, extension of the desert lands and reduction of floods and droughts.
  • To increase the forest cover through social forestry and afforestation.
  • Toincreasetheproductivityofforeststomaketimber,fuel,fodder and food available to rural and tribal population dependent on forests.
  • To encourage the substitution of wood.
  • To create a massive peoples movement involving women to encourage planting of trees and to stop felling of trees.

NCERT Solutions for Class 11 Geography Chapter 5 Natural Vegetation

Based on the forest conservation policy following steps were initiated :

(i) Social forestry – Social forestry programme has encouraged farmers to plant trees on their own farms, wood lots are planted by the forest department for the needs of the community especially along road sides, canal banks and other such public lands. This programme has classified into urban, rural and farm forestry.

(ii) How can people’s participation be effective in conserving forests and wildlife?
Answer:
People can help in raising the social forestry programme. They can plant trees on their own farms, wood lots are planted by the forest department for the needs of the community especially along road sides, canal banks and other such public lands and community wood lots are planted by the community themselves on economically lands to be shared equally by them.

Wild life conservation has a very large ambit for the well being of ‘ humankind. This can be achieved only when every individual understands f its significance and contributes his bit. For this purpose Project Tiger (1973) and Project Elephant (1992) have been launched to conserve these species.

The main objective of the scheme is to ensure the maintenance of the viable population of tiger and preserve areas of biological importance as natural heritage for their benefit. For this purpose of effective conservation of flora and fauna special steps have been initiated. People can help in maintaining the stability of ecosystem by forestering other trophic levels in food chain which is essential to ensure an ecologically viable population of tiger.
