    (b) Democracies resolve conflict in a better way than others.
    (c) Democratic government is more accountable to the people.
    (d) Democracies are more prosperous than others.

    Answer

    Option ‘D’ Democracies are more prosperous than others is not a good argument in favour of democracy as there are many countries such as Sri Lanka, India which opted for democracy but not prosperous where other countries such as China or Saudi Arabia which have communist and monarchy rule respectively are more prosperous. The prosperity of any country depends on the correct policies of the government. It also depends on the availibility of natural resources not with the form of government. Democracy can’t guarantee prosperity.

    7.Write a response to the following arguments against democracy.
    (a) Army is the most disciplined and corruption-free organisation in the country. Therefore army should rule the country.
    (b) Rule of the majority means the rule of ignorant people. What we need is the rule of the wise, even if they are in small numbers.
    (c) If we want religious leaders to guide us in spiritual matters, why not invite them to guide us in politics as well. The country should be ruled by religious leaders.

    Answer

    A democracy is  government elected by the people, from among the people themselves. The Army is integral in protecting the country, but it is not elected by the people; hence, it cannot form a democratic government. The second statement is not true as all people are intelligent to some extent. The third statement is dangerous because bringing religion into politics can cause serious conflict.

    8. Are the following statements in keeping with democracy as a value? Why?
    (a) Father to daughter: I don’t want to hear your opinion about your marriage. In our family children marry where the parents tell them to.
    (b) Teacher to student: Don’t disturb my concentration by asking me questions in the classroom.
    (c) Employee to the officer: Our working hours must be reduced according to the law.

    Answer

    (a) This statement of father is undemocratic as every adult has right to choose their life partner. The father does not have right to impose their choice on daughter.

    (b) This statement also is not under democratic setup. The student have right to ask question. This is undemocratic if his right is denied.

    (c) The third statement is democratic as it calls for a rule of law which is beneficial for the employees.

    9. Consider the following facts about a country and decide if you would call it a democracy. Give reasons to support your decision.
    (a) All the citizens of the country have right to vote Elections are held regularly.
    (b) The country took loan from international agencies. One of the conditions for given loan was that the government would reduce its expenses on education and health.
    (c) People speak more than seven languages but education is available only in one language, the language spoken by 52 percent people of the country.
    (d) Several organisations have given a call for peaceful demonstrations and nation wide strikes in the country to oppose these policies. Government has arrested these leaders.
    (e) The government owns the radio and television in the country. All the newspapers have to get permission from the government to publish any news about government’s policies and protests.

    Answer

    (a) This is democracy as only democratic setup allow right to vote and also election at regular time period.

    (b) A democratic country has to look after the welfare of its people. The condition of reducing of expenses on health and education is against the welfare of the people.

    (c) In democracy, education is available in all languages as it basic right. Official language can be the language of majority of people.

    (d) In a democracy, people have right to express their opinion in peaceful manner. It is undemocratic behaviour.

    (e) This is undemocratic nature as in democracy freedom of press and media is must. If government own radio and television then freedom of press violated.

  • Concept’s of What is Democracy? Why Democracy? Class 9th Social Science Civics

    WHAT IS DEMOCRACY?

    1.Democracy is a form of government in which the rulers are elected by the people.

    • Myanmar where the army rules, Dictator Pinochet’s rule in Chile, or President
      Nkrumah’s rule in Ghana was not democratic. They were not chosen by the people.
    • Hereditary kings, like the king of Nepal or Saudi Arabia, are also not democratic rulers.
      They rule because they were born into noble families.

    2. In a democracy final decision making power must rest with those elected by the people.


    •  In Pakistan, President Musharraf has the power to dismiss national and state assemblies; so the final powers rest with the army and the General himself. We cannot call it a democracy.

    3. A democracy must be based on a free and fair election where those currently in power have a fair chance of losing.

    • For example, in Mexico elections have been held every six years since 1980. But the same party, PRI, has won the elections. Obviously, there has been rigging and malpractices, with freedom denied to the opposition. This is not what a democracy should be.

    4. In a democracy, people’s will is ascertained by each adult citizen having one vote and each vote has one value. Democracy is based on the fundamental principle of political equality.

    5. A democratic government rules within limits set by constitutional and citizens’ rights.

    • A democratic government cannot do what it likes after winning the elections. It has to
      respect certain basic rules and is accountable not only to the people but also to other
      independent officials.


    WHY DEMOCRACY?

    Points Against
    There has been a criticism of democracy by various people. The charges are that :
    It creates instability by changing its leaders frequently.

    • Democracy is about power play and political competition. There is no scope for morality.
    • So many people have to be consulted before any issue is solved. It leads to delay.
    • Elected leaders do not know the best interest of the people.
    • It leads to corruption for it is based on electoral corruption.
    • Ordinary people do not know what is good for them, so decision making should not be
      left to them.

    NCERT Solutions for Class 6th Social Science: Chapter 6 – Major Landforms of the Earth

    Class 6 Social Science (Geography) Chapter 6 Major Landforms of the Earth NCERT Solution is given below.

    Question 1:
    Answer the following questions briefly.
    (a) What are the major landforms?
    (b) What is the difference between a mountain and a plateau?
    (c) What are the different types of mountains?
    (d) How are mountains useful to man?
    (e) How are plains formed?
    (f) Why are the river plains thickly populated?
    (g) Why are mountains thinly populated?

    Answer:
    (a) The major landforms are: mountains, plateaus and plains.
    (b)

    Mountain Plateau
    A mountain is any natural elevation of the Earth’s surface. It is considerably higher than the surrounding area. A plateau is an elevated flat land. It is a flat-topped table land standing above the surrounding area.
    Mountains have peaks. Plateaus are flattened highlands.

    (c) The different types of mountains are: fold, block and volcanic.
    (d)
    Usefulness of Mountains
    Mountains are a storehouse of water. Many rivers have their source in the glaciers. Reservoirs are made to harness this water for consumption, irrigation and generating electricity.
    River valleys and terraces are ideal for cultivation of crops.
    Mountains have a rich variety of flora and fauna. Mountains provide an idyllic site for tourists.
    (e) Most of the plains are formed by rivers and their tributaries. The rivers flow down the slopes of mountains and erode them. They carry forward the eroded material. Then they deposit their load (consisting of stones, sand and silt) along their courses and in their valleys. It is from these deposits that plains are formed.
    (f) A lot of flat lands are available in plains. Also, the available land is generally fertile. Hence, plains are the most useful areas for human habitation as well as for cultivation. Transport network can also be easily constructed in plains. Thus, plains are very thickly populated regions of the world.
    (g) Mountains have very harsh cold climate. The slopes of the mountains are very steep. Also, mountains offer very little land for farming. For these reasons, mountains are thinly populated.

    Question 2:

    Question 1:
    Answer the following questions briefly.
    (a) What are the three components of a map?
    (b) What are the four cardinal directions?
    (c) What do you mean by the term ‘the scale of the map’?
    (d) How are maps more helpful than a globe?
    (e) Distinguish between a map and a plan.
    (f) Which map provides detailed information?
    (g) How do symbols help in reading maps?

    Answer:
    (a) The three components of a map are: distance, direction and symbol.
    (b) The four cardinal directions are: North, South, West and East
    (c) The scale of a map is the ratio between the actual distance on the ground and the distance shown on the map.
    (d) A globe is useful when we want to study the Earth as a whole. But, when we want to study only a part of the Earth, it is of little help. For this purpose, we use maps. A map can represent the entire Earth’s surface or a part of it.
    Maps can be used to show the physical features of the Earth (mountains, plains, oceans, rivers, etc.), the political divisions of the Earth (countries, states, cities, villages, etc.), and certain specific information (roads, rainfall, forests, industries, etc.)
    (e)

    Map Plan
    A map is a representation or a drawing of the Earth’s surface or a part of it drawn on a flat surface according to a scale. A plan is a drawing of a small area on a large scale.
    It can be used for representing large areas like continents or countries (large scale maps), and also for representing a small area like a village or a town (small scale maps). It is used for representing those things  that cannot be represented in a map. For example, the length and the breadth of a room cannot be shown in a map. For this purpose, a plan is used.

    (f) A large scale map provides detailed information.
    (g)As it is not possible to draw on a map the actual shape and size of different features (e.g., buildings, roads, bridges), they are shown by using certain standard letters, shades, colours, pictures and lines. These symbols give a lot of information in a little space. Using these symbols, maps can be drawn easily. The use of symbols makes maps simple to read.

    Question 2:
    Tick the correct answers.

    Class 6 Social Science (Geography) Chapter 3 Motions of the Earth NCERT Solution is given below.

    Question 1:

    Answer the following questions briefly.
    (a) What is the angle of inclination of the Earth’s axis with its orbital plane?
    (b) Define rotation and revolution.
    (c) What is a leap year?
    (d) Differentiate between the Summer and Winter Solstice.
    (e) What is an equinox?
    (f) Why does the Southern Hemisphere experience Winter and Summer Solstice in different times than that of the Northern Hemisphere?
    (g) Why do the Poles experience about six months day and six months night?

    Answer:

    (a) The angle of inclination of the Earth’s axis with its orbital plane is 66½°.
    (b) Rotation is the movement of the Earth on its axis. Revolution is the movement of the Earth around the Sun in a fixed path or orbit.
    (c) Earth takes 365¼ days to revolve around the Sun. However, for the sake of convenience, we consider a year as consisting of 365 days. The six hours (1/4th of 24 hours) that are ignored make one day (24 hours) over a span of four years. This surplus day is added to the month of February. Thus, every fourth year, February has 29 days, and such a year (with 366 days) is known as a leap year.
    (d)

    Summer Solstice Winter Solstice
    It is the position of the Earth when the rays of the Sun fall directly on the Tropic of Cancer. It is the position of the Earth when the rays of the Sun fall directly on the Tropic of Capricorn
    In this position, the North Pole is tilted towards the Sun. In this position, the North Pole is tilted away from the Sun.
    A larger portion of the Northern Hemisphere gets light from the Sun; hence, it is summer in the Northern Hemisphere. A larger portion of the Southern Hemisphere gets light from the Sun; hence, it is winter in the Northern Hemisphere.
    During this period in the Northern Hemisphere, days are longer than nights. During this period in the Northern Hemisphere, nights are longer than days.

    (e) Equinox is the position of the Earth when the rays of the Sun fall directly on the Equator. At this position, neither of the Poles is tilted towards the Sun. As a result, the entire Earth has equal days and equal nights.
    (f) When the North Pole is tilted towards the Sun, the Northern Hemisphere experiences Summer Solstice. At this time, since the South Pole is tilted away from the Sun, the Southern Hemisphere experiences Winter Solstice. When the North Pole is tilted away from the Sun, the Northern Hemisphere experiences Winter Solstice. At this time, since the South Pole is tilted towards the Sun, the Southern Hemisphere experiences Summer Solstice.
    (g) The Poles experience about six months of day and six months of night because of the tilt of the Earth on its axis. Because of this tilt, each Pole is tilted towards and away from the Sun for about six months each.
    When the North Pole is tilted towards the Sun, it experiences continuous daylight for six months. It is night for the same time period at the South Pole. These conditions are reversed when the South Pole is tilted towards the Sun.
