2. Answer the following Questions:

Question a.
Differentiate between the physiography of Brazil and India
Answer:

The Physiography of India The Physiography of Brazil
The physiographic divisions of India are the Himalayas, the North Indian Plains and the Peninsula, Coastal Plains, and the Islands. The physiographic divisions of Brazil are: The Highlands, The Great Escarpment, The Coastal region, The Plains and The Islands.
There are long and high mountain ranges in northern and north eastern part of India in the form of Himalayan ranges. The Western Ghats and the Eastern Ghats lie to the west and east of the Peninsular region. The average altitude of the Greater Himalayas is around 6000m. In Brazil there are no high and continuous mountain ranges. The eastern side of the Highlands is demarcated because of the Escarpment. The Great Escarpment located in south-eastern part of the Highlands has an altitude of 790m in this region with the height gradually decreasing.
In India the Plains occupy a wide area in the north. The Plains lie between the Himalayas in the North and the Peninsula in the South. It extends from Rajasthan in the West to Assam in the East. The Coastal Plains lie to the west and east of the Peninsula. In Brazil the Amazon Basin in the North and the Parana-Paraguay Basin to the South West constitutes the Plains. Also a narrow coastal plain is confined to the North and the East.
The Peninsular Plateau region of India lies to the South of the North Indian Plains and is divided into 2 groups, the The Central Highlands and the Deccan Plateau. In Brazil the Highlands occupy an extensive area in the South and is described as the Brazilian Highlands or the Brazilian Shield. Also to the North lies the Guyana Highland.
The islands in India are either volcanic or coral in origin. The islands in Brazil are mainly depositional and some of them are coral in nature.

Question b.
What measures are being taken to control pollution in the rivers of India?
Answer:
Rivers in India are getting polluted due to the sewage and effluents being added to it and thus affecting its quality. Following measures are being taken to control pollution in the rivers in India.

(i) Treating of the sewage before draining it into the rivers.
(ii) Reducing the use of pesticides and insecticides as they drain into the water sources and pollute it.
(iii) Discharge of industrial effluents into rivers without proper treatment is now controlled.
(iv) Reusing the water for different purposes which reduces the overuse and pollution of water.
(v) Carrying out the cleaning and purification of the river water under the National River Conservation Plan (NRCP).
(vi) Creating awareness in the people about the importance of rivers and harmful effects of pollution.
(vii) Setting up of Pollution Control Boards (PCB) at the state and national level to curb pollution.

Question c.
Explain the characteristics of the North Indian Plains.
Answer:
(i) This division lies between Himalayan Mountains in the north and the Peninsula in the south.

(ii) Similarly, it extends from Rajasthan and Punjab in the west to Assam in the east.

(iii) It is mostly a flat low lying area.

(iv) The North Indian Plains are divided into two parts. The part lying to the east of the Aravalis is the basin of the river Ganga and is therefore known as the Ganga Plains. It slopes eastward.

(v) Most of the Indian state of West Bengal and Bangladesh together constitute the delta of Ganga-Brahmaputra system. It is known as the Sunderbans. It is considered to be the world’s largest delta.

(vi) The western part of the North Indian Plains is occupied by desert known as the Thar Desert or Marusthali. Most of Rajasthan is occupied by this desert.

(vii) To the north of the desert lie the plains of Punjab.

(viii) This region is spread to the west of Aravalis and Delhi ranges. These plains have formed as a result of the depositonal work by river Satluj and its tributaries. The slope of the plains is towards the west.
Because the soil here is very fertile, agriculture is largely practised in this region.

Question d.
What could be the reasons behind the formation of swamps in the extensive continental location of Pantanal?
Answer:
Pantanal is one of the largest wetlands in the world, lying in the south west part of the highland areas.
It is a region of swamps and marshes in northwestern part of Mato Grosso do Sul in Brazil and it extends into Argentina too.
This region is drained by the river Paraguay and its tributaries.
They collect the water from the highland areas and deposit the sediments in the low lying Pantanal region.
Pantanal is a gently sloped basin which is submerged throughout the year due to the filling of the sediments and water in the depression area of the Pantanal.

Question e.
Which are the major water divides of India give examples.
Answer:
A mountain or an upland which separates two drainage basins is known as a Water Divide. The major Water Divides of India are :

Western Ghats: The Western Ghats acts as a water divide and separates the west flowing rivers like Zuari, Mandvi, Vaitama draining into the Arabian Sea, from the east flowing rivers like the Godavari, Krishna and Kaveri draining into the Bay of Bengal.

Vindhya ranges: It divides the drainage basin of the River Ganga and the River Narmada.

Aravali ranges : The Aravali ranges separate the west flowing river Luni from the east flowing river Banas.

Satpuda ranges: The Satpudas separate the Narmada drainage basin and the Tapi drainage basin.

4. Write geographical reasons:

Question a.
There are no west flowing rivers in Brazil.
Answer:
(i) Many rivers originating from the terminal portion of the Brazilian highlands flow northwards to meet the Amazon river and finally terminate in the Atlantic Ocean.

(ii) Sao Francisco River flows 1000 kms towards the north and then turns east to join the Atlantic Ocean.

(iii) The rivers Parana, Paraguay and Uruguay originating from the southern part of Brazilian highlands flow southwest and enter Argentina.

(iv) The Amazon river, originating from the Andes mountain in the west flows eastwards to meet the Atlantic Ocean.

(v) Thus, there are no west flowing rivers in Brazil.

Question b.
There are dissimilarities between the eastern and the western coast of India.
Answer:
(i) The western coast borders the Arabian Sea and the eastern coast borders the Bay of Bengal.

(ii) The western coast is by and large a rocky coast. At places, spurs starting from the Western Ghats have extended right up to the coast. The eastern coast has been formed as a result of depositional work of rivers.

(iii) The width of the western coast is narrow, whereas that of the eastern coast is wide.

(iv) Short and swift rivers originating from Western Ghats form estuaries on the western coast, whereas, because of the gentle slope the east flowing rivers flowing at low speed deposit sediments and form deltas on the eastern coast.

(v) Thus there are dissimilarities between the eastern and the western coasts of India.

Question c.
There are fewer natural ports on the eastern coast of India.
Answer:
(i) The eastern coast borders the Bay of Bengal. It has been formed as a result of depositional work of rivers.
(ii) Many east flowing rivers have formed deltas at their mouth due to the gentle slope.
(iii) Sediments deposited by the river makes the coast shallow.
(iv) Therefore there are fewer natural ports on the eastern coast of India.

Question d.
As compared to Amazon, the pollution in river Ganga affects human life greatly.
Answer:
(i) The Amazon Basin is a sparsely populated region of Brazil.. Unfavourable climate, heavy rainfall, inaccessibility and dense forest are the barriers for development of human settlements and industrialisation here.

(ii) On the other hand, the Ganga Plain region is one of the most densely populated regions of India.

(iii) Due to flat fertile plains, availability of water, suitable climate, dense human settlements have been established in this region.

(iv) Mining activities in the Amazon Basin causes pollution in the Amazon River, whereas industrial and domestic sewage adds to the pollution of

River Ganga. Thus as compared to Amazon, the pollution in River Ganga affects human life greatly, as the Ganga Plain is more densely populated as compared to the Amazon Plains.

3. Give reasons:

Question a.
Per capita land availability is more in Brazil as compared to India.
Answer:

  • India occupies 2.4% land area of the world and supports 17.5% of the world’s total population.
  • Brazil occupies 5.6% of land area of the world and supports only 2.75% of the world’s total population.
  • Average density of population in India is about 382 persons per sq. km. while average density of population in Brazil is around 23 persons per sq. km.
  • Thus Brazil’s population is lesser than India, but it occupies a larger land area than India.
  • So, the per capita land availability is more in Brazil as compared to India.

Question b.
There is mixed economy in Brazil and India.
Answer:

  • In a mixed economy there is a co-existence of public sector and private sector.
  • In Brazil, sectors like health, banking, telecommunications, railways and airways are owned and managed by both public and private sectors.

3. Answer the following questions:

Question a.
Explain the similarities and differences between the population distribution in Brazil and India.
Answer:
(a) Similarities in population distribution in Brazil and India:

  • In Brazil as well as in India, population is very unevenly distributed.
  • Inaccessible dense forests and absence of facilities are the barriers to human settlements.
  • North, north west and north east of both the countries are the regions of low population.
  • Population is concentrated in flat fertile regions which have abundant water resources, transport facilities, mild climate and development of agriculture industries and trade in the plain region.
  • Coastal regions are densely populated in Brazil and in India.

(b) Differences between population distribution in Brazil and India.

  • The average density of population in India is 382 persons per sq.km, and that of Brazil is about 23 persons per sq.km.
  • Though the area of both the countries is occupied by vast river basins, the distribution of population is extremely opposite in both the river basins.
  • The Amazon River Basin is sparsely populated while the Ganga River Basin is densely populated.

Question b.
Giving examples, correlated to, climate and population distribution
Answer:
Climate and population distribution are closely interreleted. Temperature and rainfall, the two elements of climate greatly influence the population concentration.

(i) Dense population is found in regions with mild climate and moderate rainfall.
E.g. the coastal plains of Brazil, the northern plain as well as the coastal plains of India

(ii) Places with heavy rainfall, inaccessibility and dense forests have low population.
E.g. the interiors of the Amazon Basin in Brazil, north eastern states in India.

(iii) The snow covered regions due to extremely cold climatic conditions have less population.
E.g. the northernmost part of Jammu & Kashmir.

(iv) In certain regions, due to less rainfall and extreme climatic conditions population is sparse.
E.g. Thar desert of Rajasthan and the Drought Quadrilateral region of Brazil.

4. Give geographical reasons:

Question a.
Population is an important resource.
Answer:

  • The qualitative aspects of a population are important for a nation’s economic and social progress.
  • Natural resources of any country gets utilised properly because of the population.
  • Economic growth and development will be slow if population resource is not utilised properly.
  • Thus an optimum and quality population can bring about a country’s development.

Question b.
Brazil’s population density is very less.
Answer:

  • Brazil is the fifth largest country in the world with respect to area and has a population of about 19 crores (Census 2010).
  • It occupies 5.6% of world’s total land area and accounts for only 2.78% of the world’s total population.
  • Thus Brazil occupies more percent of world’s land and less percent of world’s total population. Therefore,
  • the density of population is very less in Brazil, i.e. around 23 persons per sq.km.

Question c.
India’s population density is high.
Answer:

  • India is the second most populous country in the world, with a population of about 121 crores (Census 2011).
  • India occupies only 2.41% of the land area of the world, but supports 17.5% of the world’s population.
  • Thus India has less percent of world’s land and supports high percent of world’s population.
  • Hence, India’s average population density is high i.e. 382 persons per sq. km.

Question d.
The density of population is sparse in the Amazon Basin.
Answer:

  • The interior part of the Amazon Basin has a very unfavourable hot and humid climate.
  • It receives heavy rainfall of nearly 2000 mm and has dense inaccessible forests.
  • Transportation, agricultute and industries are not well developed here.
  • All these factors are barriers to the development of human settlements.
  • So, the density of population is sparse in the Amazon Basin.

Question e.
Population density is high in the Ganga plains.
Answer:

  • Ganga plains are fertile low lying plains formed due to the deposition work of River Ganga and its tributaries.
  • Mild climate, moderate rainfall and fertile soil have led to the development of agriculture and industries.
  • This region also has a dense network of roadways and railways.
  • So, the population density is high in the Ganga Plains.

5. Observe the following diagram and answer the following questions:

Answer:
Some of the reasons for lower sex ratio in any region are:

  • Illiteracy: Narrow mindedness and lack of education leads to gender bias in the society.
  • Preference for a male child : There is preference of a boy child over a girl child. Nutrition to girls is ignored.
  • Poverty: Povertystruck families do not prefer a girl child as they consider female child a burden due to practices like dowry prevalent in the society.
  • Female foeticide and female infanticide: Female foeticide and female infanticide are on the rise due to the wrong use of modem technology.
  • Maternity deaths: Higher maternity deaths have lowered the sex ratio.

Question 7.
Explain – The growth rate of population in India is decreasing but population is increasing.
Answer:
(i) Growth rate of population is calculated on the basis of difference between birth rate and death rate.
(ii) Earlier the difference between birth rate and death rate was high, so the growth rate was high.
(iii) Today the growth rate is decreasing because the difference between birth rate and death rate is not as high as it was earlier.
So it is said that in India the growth rate of population is decreasing, but the population is increasing.

Question 8.
Explain the uneven distribution of population in India.
Answer:
(i) Dense population is found in regions with mild climate and moderate rainfall. E.g. the northern plain as well as the coastal plains of India
(ii) Places with heavy rainfall, inaccessibility and dense forests have low population. E.g. north eastern states in India.
(iii) The snow covered regions due to extremely cold climatic conditions have less population. E.g. the northernmost part of Jammu & Kashmir.
(iv) In certain regions, due to less rainfall and extreme climatic conditions population is sparse. E.g. westernmost part of India in the Thar desert, Rajasthan.

Answer:
Wrong – India and Brazil have different seasons at the same time.

Question c.
India faces tropical cyclones frequently.
Answer:
Right.

Question d.
Brazil gets a lot of rainfall because of the southwest monsoon winds.
Answer:
Wrong – Brazil gets rainfall from South-East Trade Winds and North-East Trade Winds.

3. Give geographical reasons:

Question a.
The north-eastern part of Brazilian Highlands receives very less rainfall.
Answer:
(i) Brazil gets rainfall from the South-East Trade Winds and the North-East Trade Winds.
(ii) Parts of the Brazilian Highlands extend upto the northern coast.
(iii) The Escarpments act as an obstruction to the winds blowing from the sea and cause orographic type of rainfall in the coastal region.
(iv) Beyond the Highlands, the effect of these winds gets reduced. As a result, the rainfall is minimal.
(v) Thus the North Eastern part of Brazilian highlands receives less rainfall. This rain shadow region is also called the ‘Drought Quadrilateral’.

Question b.
Snowfall doesn’t always occur in Brazil.
Answer:
(i) Because of the vast latitudinal extent of Brazil, it experiences a wide range of climatic variations. Near the Equator it is hot, while tropical type of climate is found near the Tropic of Capricorn.

(ii) Considering the temperatures in Brazil, the northern part of Brazil is hot while the temperatures in the southern part are comparatively lower.

(iii) It generally snows in those areas lying in the temperate or polar regions or in the mountainous regions of very high altitude.

(iv) Snowfall does occur but is only confined to higher elevations in the southern states of Rio Grande Do Sul, Parana and Santa Catarina.

(v) Most part of the country lies in the tropical zone which experiences a hot and humid climate.

So snowfall doesn’t always occur in Brazil and is considered a rare phenomenon.

Question c.
Convectional type of rainfall is not prominent in India.
Answer:
(i) Convectional rains are a feature of the equatorial regions and the equator passes through the northern part of Brazil.
(ii) Due to the intense heat here the air expands and rises upwards. As the air goes upwards it cools down, condensation occurs and clouds are formed. This leads to convectional rains every day.
(iii) As such conditions do not exist in India, convection rainfall is not prominent here.

Question d.
Tropical cyclones occur rarely in Brazil.
Answer:
(i) In the coastal regions of Brazil near the Equator, differences in temperatures are negligible.
(ii) The winds move in the vertical direction in this equatorial region.
(iii) Similarly, the convergence zone of the trade winds is weak here. As a result, cyclones are not formed.
(iv) As a result tropical cyclones occur rarely in Brazil.

Question e.
There is not much difference in the range of temperature in Manaus.
Answer:
(i) Manaus is located to the north of Brazil and close to the Equator.
(ii) This region receives perpendicular rays of the sun throughout the year.
(iii) It also receives convectional type of rainfall every day.
(iv) So the climate is hot and humid throughout the year.
(v) As, there is not much difference in the maximum and minimum temperatures there is not much difference in the range of temperature in Manaus.

So, it is said that India receives precipitation from the North East Monsoon Winds too.

4. Answer the following questions:

Question a.
Describe in brief the changes occurring in the climatic conditions of India while going from south to north.
Answer:
(i) India’s Climate is of monsoon type. But there is diversity in climatic conditions of India due to the latitudinal location and altitude of the place.

(ii) As the Tropic of Cancer passes through middle of India, it divides the country into tropical region and sub tropical region.

(iii) The tropical region receives nearly vertical rays of the Sun and the temperature increases as we move towards the south.

(iv) In the sub tropical region of the north, summers are very hot and winters are very cool and dry.

(v) The Himalayas lie in the northern part of India. They protects us from the cold winds that blow from the north, obstructs the South West Monsoon Winds which results in orographic rainfall in its southern slopes.

(vi) In major parts of India precipitation is in the form of rainfall, but in the Himalayas it is in the form of snowfall.

Question b.
Explain the importance of the Himalayas and the Indian Ocean with respect to the climate of India.
Answer:
(i) The Indian Ocean and the Himalayan ranges exert a great influence on the climate of India and the origin of monsoons.

(ii) Because of high temperatures in summers, a low pressure area develops in the Punjab Plains and the Thar Desert of Rajasthan.

(iii) At the same time a high pressure region develops over the Indian Ocean.

(iv) This attracts winds and they start blowing from the Indian Ocean towards the mainland India.

(v) These are moisture-laden winds which bring rainfall to India.

(vi) These winds move towards the Himalayas and due to the natural obstruction of the Himalayas, orographic rain occurs.

(vii) Later these winds retreat from the Himalayas and move from the north-east towards the Indian Ocean and brings rain to some parts of the Peninsula.

(viii) Also the severe cold winds blowing from the north are obstructed by the Himalayas and it saves India from severe winters.

Question c.
Discuss the factors affecting the climate of Brazil.
Answer:
(i) Brazil experiences wide range of climatic variations due to its vast latitudinal extent, proximity to the Equator, presence of the Atlantic Ocean and the Great Escarpment.

(ii) The northern part of Brazil near the Equator is hot, while temperate type of climate is found near the Tropic of Capricorn.

(iii) Brazil gets rainfall from the South-East Trade Winds and the North-East Trade Winds blowing from the Atlantic Ocean.

(iv) Convectional rainfall occurs in places near the equator. Whereas, the Escarpment act as an obstruction to the winds blowing from the sea and cause orographic type of rainfall in the coastal region.

(v) Beyond the Highlands the effects of these winds gets reduced, as a result the rainfall is minimal. This region is a rain-shadow region and is called ‘The Drought Quadrilateral.’

(vi) The Equator passes through the northern part of Brazil so the temperature here is high. Average temperature of Amazon valley is 25°-28°C. Climate is cooler in the highlands. While the temperatures in the southern part are comparatively lower.

(vii) In the coastal regions near the Equator in Brazil, differences in temperatures are negligible. Because of the proximity to the sea, the coast experiences mild and humid climate.

(viii) The winds move in the vertical direction in this region. Similarly, the convergence zone of the trade winds is weak here. So the tropical cyclones are a rare phenomena here.

Class 8 Science Chapter 9 Disaster Management Question Answer Maharashtra Board

1. Answer the following in your own words.

Question a.
Explain the relation between continuous rains and landslide. Give reasons.
Answer:
Before the actual landslide, many changes occur in the surrounding hilly ground. The hard rocks develop cracks and crevices. These are natural changes but due to man-made activities, the cracks are widened due to erosion. These cracks make the big rocks to break into smaller stones. The cracks widen further due to excessive rainfall. These rocks further get eroded and they fall down along with soil from the slopes. The entire process is speeded up due to rainwater.

Maharashtra Board Class 8 Science Solutions Chapter 9 Disaster Management

Question c.
What are the specifications of an earthquake-proof building?
Answer:
The earthquake-proof building is such that even if the earthquake is caused, it should not cause damage to the buildings due to these earth movements. There are some codes of conduct while constructing such buildings. Advanced technology is used for earthquake resistant construction. The foundation of earthquake-proof building is separated from lower land. The walls are of less weight or they are wooden. The house constructed with special light materials are preferred in earthquake-prone regions.

Question d.
Explain the effects of landslide.
Answer:
1. Mostly rivers originate in the hills and mountains. When there is landslide, the rivers naturally get flooded.
2. The paths of the riverine water changes due to landslide.
3. Waterfalls are displaced from their original positions.
4. New and artificial water reservoirs are created.
5. The falling debris, soil and rocks make the trees at the base of hillside uprooted. All the plant life is lost.
6. The constructions done by the villagers on the slope can be totally damaged due to landslide. There is large scale damage to property and life. In few cases like Malin the entire village was buried due to landslide and accompanied rainfall.
7. Transportation is affected as the roads and railway tracks are blocked due to debris.

Maharashtra Board Class 8 Science Solutions Chapter 9 Disaster Management

Question e.
Is there any relation between dam and earthquake? Explain.
Answer:
There is abundant water stored in the dams. This water column puts additional weight on the ground. Initially there may not be any weight, but later due to construction of dam, suddenly the pressure of this weight is so high that this ground experiences the tension. If such area is already earthquake-prone, then there can be chances of earthquake. According to theory of plate tectonics, there are continuous movements in the earth’s surface. If over such fragile plates, the dams are constructed then the chances of earthquake are enhanced.

2. Give Scientific reasons.

Question a.
It is safer to find shelter under things like a bed, table at the time of earthquake.
Answer:
When earthquake takes place, due to the vibrations in the earth’s surface, there is possibility of the roof and walls of the house to fall. This collapse can cause severe head injury which can be fatal. Thus, one must take shelter below the hard-supporting structures such as bed or table. This precaution can save one’s life.

Question b.
In monsoon, don’t take shelter near hillside.
Answer:
The excessive rainfall can cause landslides. The soil and rocks from the hillside can be pushed down along with the flow of rainwater. This debris slides to the lower heights from the hills. This explains us that taking shelter near the base of the hillside can be disastrous as one can be buried in the debris due to sudden landslide. Therefore, in monsoon, one should not take shelter near hillside.

Maharashtra Board Class 8 Science Solutions Chapter 9 Disaster Management

Question c.
Don’t use lifts at the time of earthquake.
Answer:
Lifts or elevators run on electricity. The electricity supply can be hindered due to earthquake. There may be chances of fire due to short circuit. We may get trapped in the elevator at such times. The building may also collapse due to earthquake. It is always better to use stairs at the time of such calamities, so that one can safely come out of the building. Therefore, it is said that lifts should not be used at the time of earthquakes.

Question d.
The foundation of earthquake- proof building is separated from lower land.
Answer:
The surface of the earth trembles at the time of earthquake. These tremors cause seismic waves which are responsible for the movements of the earth’s surface. The ground thus shakes or it goes up-down. These shocks and waves formed in the interior of the earth spread on the surface in all directions. This causes collapse of the building and other structures on the land.
To prevent such disasters the foundation of earth-quake proof building is separated from lower land.

3. If a crowd gathers at the place of earthquake, what would be the difficulties in relief work?

Question a.
If a crowd gathers at the place of earthquake, what would be the difficulties in relief work?

Write short notes:

Question 1.
Types of fire:
Answer:
There are five types of fire. This division is based on two criteria, viz.
(i) Which substance is being burnt, (ii) What is the method of extinguishing it.
1. Class A Fire: Commonly inflammable solid things such as wood, clothes, coal, papers can be burnt by this type of fire. This fire is extinguished by spraying water over it. This is also called cooling out. Water is effectively used to put off class A fire.

2. Class B Fire: Flammable liquid substances such as petrol, oil, varnish, solvents, cooking oil, paints, etc. catch fire and it is called class B fire. Since these substances are lighter than water, they can be extinguished only by foaming fire extinguishers.

3. Class C Fire: The fire caused due to gaseous substances is called class C fire. Domestic gas (L.P.G.) and acetylene can cause such kind of fire.

4. Class D Fire: Combustible metals catch class D fire. Metals such as potassium, sodium and calcium, can react with water at normal room temperature whereas magnesium, aluminium and zinc react with water at high temperature. When both these groups combine with water, it causes explosion.

5. Class E Fire: When electric components are subjected to fire, they form class C fire. Such fires can be caused by short circuit or due to problems in electric fittings. Such fire is extinguished with the help of carbon dioxide and non-conductive fire extinguishers.

Question 2.
Disaster relief – planning.
Answer:
Anyone can face disaster at any time. The only way to tackle with such disasters is to keep preparedness to deal with any calamity. Schools, colleges and various offices need to chalk out a detailed planning in case of possible disasters. With this purpose in mind, disaster relief planning is done.

E.g. In the disaster relief planning for school, primary information of the school, the structure of School Disaster Management Committee, detailed information about school building and information about school ground, daily routine of the school such as at what time the school starts and what time does it end, the possible hazards in the school, and disaster management map of the school is included.

Answer the following questions:

Question 1.
What are the different ways to extinguish fire? Write briefly about them.
Answer:
There are three main methods to extinguish the fire. These methods are used to stop the spread of fire and to avoid the financial and other losses.
1. Cooling out by use of water: Water is easily available and can be used for putting off fire instantly. Due to spraying of water, there is cooling effect produced which helps in reducing the loss by fire. Fire can be easily controlled by water.

2. Suppressing the fire by covering it: When there is a fire due to electricity or oil it has to be controlled by covering the fire by sand or soil. When the froth is spread on the fire, there is no contact between air and fire. This puts off the fire and stops the spread of fire caused due to oil.

3. Keep away Flammable Substances: Care is taken to keep away all flammable substances from the fire. Wooden articles and inflammable substances are kept in such as way the fire will not engulf it. Stirrup pumps are used to put off small fires by which the water is spread in all directions around the fire.

Maharashtra Board Class 8 Science Solutions Chapter 9 Disaster Management

Question 2
What are the safety measures and precautions to stop the fire?
Answer:

  1. Switching off the regulator of cooking gas cylinder when not in use. Put off the connections of all electrical appliances when not in use.
  2. If there is fire, call others immediately for help. Take help of others by calling them. Also help others who are in need to save their lives from fire.
  3. Get help from fire brigade by calling phone number 101.
  4. Know details about working of the fire extinguishing apparatus.
  5. Give first aid to the victim of fire. Seek immediate medical help,

Question 3.
What are the causes of landslide?
Answer:

  1. Various types of natural disasters like earthquakes, tsunami, heavy rains, storms, floods can result into landslide.
  2. The indiscriminate cutting down of the trees can result into soil erosion. Soil erosion in turn results into landslide.
  3. The construction of roads, bridges, railway tracks, etc. on the mountain slopes result into lot of digging. Such activities make soil cover loose. From the slopes the soil and rocks then can slide easily. This results into landslides.

Maharashtra Board Class 8 Science Solutions Chapter 9 Disaster Management

Question 2.
In Maharashtra where do the traffic jams occur due to landslides? Make a list of such places. Why does the landslide occur at those places only? Discuss in the classroom and suggest preventive measures.
Answer:
In Maharashtra, the landslides are very common in the hilly regions. The traffic is suspended often during rainy season when such calamity strikes. Malshej, Khandala, Kasara are some of the Ghats which are very prone to land-slide. On the tracks of Konkan railway, the landslides are very common during heavy downpour.

The regions where more landslides occur have many constructions and large scale deforestation. The traffic of Konkan railway comes to standstill after such landslide. Moreover, during heavy monsoon days, the speed of the running trains is kept very slow. The soil structure is also responsible for such landslides.

Preventive measures: There should be wire meshing done across the sides of the roads and railway tracks so that the collapsed rocks and other debris does not obstruct the traffic. Tree plantation should be carried out to prevent loosening of the soil and rock. It will also help in preventing the soil erosion.
