What are the problems in areas of high population densities?
Answer:
The ratio of the population of a country to its area is population density. While discussing population distribution, density of population is also considered. The density is calculated, as per the formula given below.
Density of population = Population of a region/Area of a region.

The problems in areas of high population densities are as follows:
1. Pollution – Pollution is one of the major reasons which people face due to high population density. Due to an increase in land degradation by making houses and flats, land pollution will be caused, water will be contaminated by a huge number of people, resulting in water pollution and huge number of vehicles will cause air pollution.

2. Overcrowded – The areas with high population density become overcrowded, which bring chaos and lack of peace in the society.
3. Lack of open space – High population density makes it difficult to get a free open space.

Question d.
What arc the problems in area of low population densities?

Answer the following questions in brief:

Question a.
Write in brief about warm ocean currents.
Answer:
1. Ocean currents that move water away from the Equator to the poles are called warm ocean currents.
2. Warm ocean currents are formed in the equatorial region and they flow towards the poles.

3. The warm currents increase the temperature and precipitation in the coastal areas along with which they flow. For example, the warm ocean currents flowing along with the coastal areas of Western Europe, Southern Alaska and Japan increases the temperature in the coastal areas along with which they flow. As its effect, the ports in the coastal areas of Western Europe, Southern Alaska and Japan do not freeze in winter.

4. Gulf stream, Agulhas, Somali, etc. are some of the warm ocean currents.

Question b.
Write in brief about cold ocean currents.
Answer:
1. Ocean currents that move water away from the poles to the Equator are called cold ocean currents.
2. Cold ocean currents are formed in the polar region and they flow towards the equatorial region.

3. The cold currents decrease the temperature and precipitation in the coastal areas along with which they flow. For example, the cold ocean currents flowing along with the coastal areas of Peru, Chile, and southeastern Africa, decreases the amount of precipitation in the coastal areas along with which they flow. As its effect, arid desert areas are formed in Peru, Chile, and southwestern Africa.

4. Falkland, Labrador, Canary, Oyashio, Benguela, etc. are some of the cold ocean currents.

Question c.
Write in brief about conveyor belt.
Answer:

1. Due to deep ocean currents, the warm water goes down and the cold water comes to the surface of the earth.
2. Thus, deep ocean currents redistribute the ocean water.
3. This redistribution of ocean water takes around 500 years to complete.
4. This redistribution (movement) of sea water is known as conveyor belt.

Question d.
Write in brief about relation between ocean currents and fishing.
Answer:

1. Algae, plankton, etc. fish food grow on a large scale in the areas where warm ocean current and cold ocean current meet.
2. Fish come in these areas on a large scale and breed. Therefore, extensive fishing
   grounds are found in the meeting point of warm and cold ocean currents.
3. For example, Grand Bank in Atlantic Ocean near the coastal region of North America, Dogger Bank near the continent of Europe, etc.

Explain the effect of the following:

Question a.

Open-Ended Question:

Question a.
With which points will you explain the effects of ocean currents?
Answer:
The effects of ocean currents can be explained with the help of the following points:

1. Temperature: Ocean currents brings change in the temperature of the coastal areas along with which they flow. For example, the warm ocean current flowing along the coastal areas of Japan increases the temperature in the coastal areas.

2. Precipitation: Ocean currents brings change in amount of precipitation in the coastal areas along with which they flow. For example, the cold ocean current flowing along the coastal areas of Chile decreases the precipitation in the coastal areas leading to formation of desert areas.

3. Occupation: Ocean currents also supports the growth of fishing occupation. The extensive fishing grounds redeveloped the meeting point of warm and cold ocean currents. For example, Grand Bank near the continent of North America.

4. Transportation: Sea transport carried out along with ocean currents increases the speed and reduces the cost of fuel.

3. Answer the following

Question A.
What are the two parts of the crust? What is the basis of classification?
Answer:

1. Continental crust and the Oceanic crust are the two parts of the crust.
2. The crust is classified on the basis of whether it lies below the land or the ocean.
3. The part of the crust lying below the continent is known as the continental crust.
4. The part of the crust lying below the ocean is known as the oceanic crust.

Question B.
Why is the upper layer of the mantle known as the asthenosphere?
Answer:

1. The upper layer of the mantle is in liquid state.
2. The rocks in the upper 100 to 200 km of the mantle melt due to the heat and magma is created. Magma chambers are found in this layer of the earth.
3. Due to the heat and pressure, the energy waves are created in mantle. These energy waves move in vertical direction and magma comes out on the surface of the earth by volcanic eruptions.
4. These endogenitic movements continuously occur in the upper layer of the mantle. Therefore, the upper layer of the mantle is known as the asthenosphere.

Question C.
Magnetosphere of the earth is a result of rotation. Explain.
Answer:
1. The average temperature of the outer core of the earth is around 5000° C. The average temperature of the inner core of the earth is around 6000° C. This difference between the temperature results in formation of vertical currents.

2. The rotation of the earth gives eddy (circular) motion to these currents.

3. Electric currents develop in these spiral eddies of liquid iron leading to generation of the magnetic field of the earth. This magnetic field is called magnetosphere. In this way, the magnetosphere is formed due to the rotation of the earth.

4 Draw neat diagrams. label them and explain.

Question A.
The interior of the earth
Answer:

Explanation:

1. Inner Core: It is the center and the hottest layer of the Earth. The inner core is solid and made up of iron and nickel.
2. Outer Core: The outer core of the Earth is similar to a very hot ball of metals. It is composed of metals such as iron and nickel. The outer core surrounds the inner core.
3. Mantle: Mantle is the widest section of the Earth. Mantle is mainly made up of semi-molten rock known as magma. The rock is hard in the upper part of the mantle, but lower down the rock is softer and begins to melt. The mantle consists of very hot and dense rock.
4. Crust: The crust is the outer layer where we live. It’s a solid rock layer divided into two types: Continental crust covers the land and Oceanic crust covers water.

Question B.
Magnetic pole and equator
Answer:

5. Give geographical reasons:

Question A.
There are discontinuities in the interior of the earth.
Answer:
1. There is a difference between the elements, temperatures and the pressure found in the three parts of the interior of the earth, viz, crust, mantle and core.

2. In the interiors of the earth, the transitional areas are found between (a) continental crust and oceanic crust (b) crust and mantle (c) upper mantle and lower mantle (d) mantle and core and (e) outer core and inner core. Therefore, there are discontinuities in the interior of the earth.

Question B.
There is correlation between the density of metals and their location in the interior of the earth.
Answer:
1. The rocks found in the crust have predominance of the compounds of silicon, aluminium, magnesium, etc. These compounds are lighter in weight. Therefore, they are found in the upper layer of the interior of the earth.

2. The elements like iron, nickel are found in the core of the earth. These elements are heavier in weight. Thus, metals with low density are found in upper level in the interior of the earth and the metals with high density are found in the lower level in the interior of the earth. Thus, there is correlation between the density of metals and their location in the interior of the earth.

Question C.
Mantle is the centre of earthquake and volcanic eruptions.
Answer:
1. The rocks in the upper 100 to 200 km of the mantle melt due to the heat and the magma is created.
2. Magma chambers are found in this layer of the earth.

3. Due to the heat and pressure, the energy waves are created in mantle. These energy waves move in vertical direction and magma comes out on the surface of the earth by volcanic eruptions. Thus, mantle is the centre of earthquake and volcanic eruptions.

Question D.
The thickness of the crust below the continents is more as compared to oceans.
Answer:
1. The density of the crust below the continents is 2.65 to 2.90 gm/cm³ The density of the crust below the oceans is 2.90 to 3.3 gm/cm³

2. As the density of the crust below the continents is comparatively low, it keeps floating on the mantle. It does not subduct into mantle. As its effect, the thickness of the crust below the continents is found to be high.

3. As the density of the crust below the ocean is comparatively high, it subducts into mantle leading to its low thickness. Thus, the thickness of the crust below the continents is more as compared to oceans.

Question E.
Earth is protected because of the magnetosphere.
Answer:

1. The ozone layer protects the earth from ultraviolet radiation.
2. The earth’s magnetosphere serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer. In this way, the earth is protected because of the magnetosphere.

Know this too:

1. The average density of the earth is 5.5 gm/cm³.
2. The rocks in the upper 100 to 200 km of. the mantle melt due to heat.
3. The mixture of molten rocks, volatiles, etc. found beneath the surface of the earth is called magma.
4. The mixture of molten rocks, volatiles, etc. erupted from volcano or fissure on the surface of the earth is called lava.

Activity:

Question 1.

• Important changes took place in political and economic spheres, i.e. these spheres, were restructured. This gave impetus to democracy.

3. Explain the following concepts:

Question 1.
Cold War
Answer:
(i) America and the Soviet Union, who were allies in the Second World War became competitors, as soon as the war was over.

(ii) The cooperation between them gave way to rivalry. This rivalry occupied a period of 40-45 years of international politics

(iii) There was no open war between these two countries; but there was such tension in their relations, that it seemed that a war would erupt any time.

(iv) The concept of Cold War is used to describe the condition where there is no actual war, but there are such tensions in the circumstances, that they may be responsible to cause war.

(v) In this period, America was already a super power, but the Soviet Union also tried to become a super power by making nuclear weapons and by increasing its military might.

(vi) The struggle for power, arms race, differences in ideologies, attitude of checkmating each other by strategies and counter-strategies gave rise to the Cold War.

Question 2.
Non-Aligned Movement
Answer:
(i) In the period of the Cold War, while the world was becoming bipolar, there were some countries which did not want to join the super power rivalry. Such nations decided to stay out of the cold war rivalry. Their policy is known as non-alignment.

(ii) The Asian and African countries, which became independent after the Second World War supported the idea of non-alignment.

(iii) This movement started from 1961 under the leadership of India’s Prime Minister Pandit Jawaharlal Nehru, President of Yugoslavia Marshall Tito, President of Egypt Gamal Abdal Nasser, President of Indonesia Dr. Sukarno and Prime Minister of Ghana Dr. Kwame Nkrumah.

(iv) The non-aligned Movement has opposed colonialism, imperialism and racism. It has encouraged the resolution of international disputes by peaceful means.

(v) India led this movement under the guidance of Pandit Jawaharlal Nehru. India continued to actively support the movement afterwards as well.

(vi) Even after the end of the Cold War, the importance of the movement has not reduced. The non-aligned movement is based on eternal principles of humanism, global peace and equality.

(vii) It has inspired the less developed countries to come together. It has encouraged the resolution of international disputes by peaceful means.

(viii) While taking a firm stand on disarmament, fostering human rights, the non-aligned movement put forth the problems of poor, undeveloped countries firmly. This movement made a demand of a New International Economic Order (NIEO).

Question 3.
Interdependence
Answer:
(i) All the countries of the world are dependent on each other for one reason or the other. However big, prosperous or developed a nation may be, it can never be self-sufficient to fulfill all its needs.

(ii) Even big nations have to depend upon other big and small nations. Thus, interdependence is an important feature of the international system, i.e. today’s global system.

Question 4.
Bipolarisation
Answer:
During the Cold War, most countries of the world joined either of the two super power blocks. Such a division of the nations of the world in two groups is bipolarisation.

Question 5.
Globalization
Answer:
(i) After the end of the Cold War, trade and economic relations between countries became more open. As it has been mentioned before, capital, labour, markets and information began circulating globally.

(ii) The give and take of ideas among people all over the world grew.

(iii) Due to the revolution in information technology, different events and developments began to be known everywhere.

(iv) The boundaries between nations did not remain as sacrosanct as they were before. All these processes are together called globalisation.

(v) Just as globalisation has brought us benefits, it has also caused losses. For example, as the economies of different countries got linked with each other, trade increased, economic unification grew, plenty of products became available in the markets; but (at the same time) the gap between the poor and rich nations did not reduce.

4. Give your opinion on the following topics:

Question 1.
What measures should the League of Nations have taken to avoid the Second World War?
Answer:
(i) League of Nations should have organised a military wing with the help of member nations to keep a check over the aggressors like Germany and Japan.

(ii) League should have reconsidered implementation of harsh term of treaties imposed on the losers to avoid the revengeful policies of dictators like Adolf Hitler.

Question 2.
Non-Alignment was necessary during the Cold War.
Answer:
(i) Yes. This was important to keep newly independent countries of Asia and Africa away from the super power rivalry.

(ii) Since these countries did not officially show allegiance to any super power, they freed themselves from the dominance of USA and USSR and could independently frame their foreign policies.

(iii) This further promoted peace and co-operation.

Question 3.
Human welfare was neglected due to the Cold War.
Answer:
(i) Yes, due to military alliances the world was gripped in the fear of a possible Third World War, which would have annihilated the entire human race.

(ii) Moreover the Arms Race diverted the resources and harnessed science for destruction rather than human welfare.
