Answer:
The amount of rain in 2 places is determined by temperature differences between them.

Question 11.
How do we have variation in vegetation and animal life?
Answer:
Temperature and rainfall affect life in very critical ways. Plants and animals depend upon heat and water.
Only certain kinds of trees and plants will grow in hot regions and some other kinds will grow in cold regions and in very cold regions, nothing grows. Thus we have variation in vegetation and animal life.

Question 12.
What are the forms of sun’s energy?
Answer:
Light, heat, UV rays, radio waves and X-rays are the forms of sun’s energy.

Question 13.
Which results in ‘Global Warming’?
Answer:
Some gases like CO₂ prevent radiation of heat from the earth. CO₂ in the atmosphere N increases due to increased use of diesel and petrol, cutting down of forests etc. If the CO₂ proportion in the atmosphere increases, then less heat will be radiated causing increase in global temperature. This results in ‘Global Warming’.

Question 14.
Appreciate the ‘green houses’.
Answer:
Green houses are also called Glass houses. Green house is a building in which plants are grown. These are climate controlled. It works by taking sunlight and heating it up. This process is the conversion of solar energy to thermal energy. It gives plants both temperate heat and a good water source. The creation of green house is excellent.

Question 15.
What are the effects of ‘Global warming’?
Answer:
Global warming is the increase of Earth’s average surface temperature due to effect of green house gases, such as carbon dioxide emissions from burning fossil fuels or from deforestation.

Question 16.
The sun is the primary source of energy. The trees are the factories which produce food from sunlight. Are we growing or cutting down such trees? Discuss the advantages of trees and our responsibility in growing them.
Answer:
We are cutting down trees more than we grow.
The advantages of Trees:

Trees can reduce air temperature by blocking sunlight. Further cooling occurs when water evaporates from the leaf surface. The conversion of water to air vapour … a chemical process …. removes heat energy from the air.
A tree can be a natural air conditioner.
Trees absorb and block noise and reduce glare.
Fallen treen leaves can reduce soil temperature and soil moisture loss.
Trees create an ecosystem to provide habitat and food for birds and other animals.
Trees absorb CO₂ and potentially harmful gasses from the air and release O₂.
Trees help to reduce surface water runoff from storms, thus decreasing soil erosion and the accumulation of sediments in streams. They increase ground water recharge and reduce the number of potentially harmful chemicals transported to our streams.
Dews and frosts are less under tree because less radiant heat is lost at night.

Project
Observe some families in your village / locality and fill up the following table.

S.No.	Name of the family head	No.of electricity bulbs used	Type			Electricity bill (in rupees)
			Bulb	Tube	CFL

Educate the families about the energy-saving measures and then conduct the same survey again after three month and compare the difference.
Answer:

S.No.	Name of the family head	No.of electricity bulbs used	Type			Electricity bill (in rupees)
S.No.	Name of the family head	No.of electricity bulbs used	Bulb	Tube	CFL	Electricity bill (in rupees)
1.	Malleswara Rao	10	4	4	2	1000 ₹
2.	Subba Rao	9	3	4	2	1200 ₹
3.	Sunil	10	4	4	2	800 ₹

Above families used more electricity bulbs especially tubes & bulbs. They are using very less CFL’s. By using more bulbs they get every month more electricity bill. That’s why, I explain to them about the importance of electricity, how we are wasting and our future generations will face the problems and I said, use more CFL’s to reduce the wastage of power & minimise the bill. After three months I went to their houses and saw the power bill really I admired because they reduce the power using and use CFL’s also. Due to this they save the power and get less electricity bill.

AP State Syllabus AP Board 8th Class Social Studies Important Questions Chapter 10 Landlords and Tenants under the British and the Nizam.

AP State Syllabus 8th Class Social Studies Important Questions 10th Lesson Landlords and Tenants under the British and the Nizam

Question 1.
Did the Zamindar own all the lands of the villages in the Mughal times?
Answer:
No. They owned some of the village lands. They had the power to collect revenue from the villagers. Rest of the land was owned by peasants and others.

Question 2.
What did the Zamindars do for the Mughal government and what did they get in return?
Answer:
The Zamindars collected the revenue from the peasantry on behalf of Mughal emperors. In return they received a share of revenue collected. Sometimes they also had right to collect some small local taxes.

Question 3.
How would the changes have affected the position of the farmers who tilled the land for several generations?
Answer:

This settlement inadvertently converted all the peasants into the tenants.
Since rent collected was much higher than the revenue, the cultivators could not pay and sometimes deserted the lands. These were the affects.

Question 4.
What is the difference between revenue and rent?
Answer:
Revenue: Tax on land which is paid to the Zamindars or government.
Rent: Amount paid to the owners of the land for using and cultivating it.

Question 5.
In what ways did the government invest in agriculture during the early British rule? Do you think it could have been done by farmers themselves?
Answer:

The Britishers made necessary advances to the ryots to purchase seeds, implements, bullocks and to repair old wells or dig new ones,
They constructed anicuts & canals. It could not have been done by farmers themselves.

Question 6.
How was a ‘dora’ different from an ordinary landlord?
Answer:
The large landlords were called Doras. They had a large retinue of servants and soldiers. Ordinary landlords were under the control of these ‘doras’. Landlords should follow the orders of ‘Doras’. This is the difference between them.

Question 7.
How do you think it was possible for the zamindars to keep increasing their incomes without increasing investment in the land?
Answer:
The prices of grains in the market rose and cultivation slowly expanded. So there was an increase in the income of Zamindars without increasing investment in the land.

Question 8.
Who do you think would have benefited from the Ryotwari Settlement – the farmers, the landlords or the British? Give reasons.
Answer:
The landlords would have benefited from the Ryotwari settlement.
Reasons:

There was an increase in the number of landlords in the Ryotwari area.
They showed much interest in giving their lands on rents rather than cultivation.

Question 9.
Why do you think the ryots did not invest in improving agriculture or extending agriculture?
Answer:
The prices rose faster than the land revenue and the ryots found it more profitable to employ tenants to cultivate their lands and receive rent from them. So they did not invest in improving agriculture or extending agriculture.

Question 10.
Who ultimately profited from production for export market and why?
Answer:
Moneylenders profited ultimately from production for export market. They lent more and more money to farmers on high-interest rates and profited.

Question 11.
Discuss the changes in the lives of traditional crafts persons and village artists.
Answer:
Traditional crafts persons are adding technology to their tradition. As the prices are high, there is no demand for their products. Village artists had enjoyed the encouragement of the Kings and Zamindars. Now they lack it. So their lives are in worse condition.

Question 12.
How are we paying the taxes nowadays?
Answer:
At present revenue is paid in the form of money.

Question 13.
Have you heard of any similar rapid rise or decline in prices of any agricultural produce in our own times? Find out about its impact on the farmers.
Answer:
In recent past, there was an increase in the prices of rice and red gram. Later they were reduced by the government. Peasants grew some crops thinking of high profits. If the demand fell, they would get losses that year.

Question 14.
Why do you think the Zamindars kept the soldiers and small forts?
Answer:
Zamindars had some villages under their control. They were the mediators between the rulers and the ruled. They had much income also. So they lived in small forts.
To protect their people from thefts and attacks, to collect revenues they needed soldiers. So they maintained them.

Question 15.
Why did the high revenue rates prevent zamindars and farmers from improving agriculture?
Answer:
As they paid heavy rates of rents and revenue from their income, they were not able to improve agriculture. They used the remaining amounts for their household purposes.

Question 16.
During the freedom movement the Zamindars normally supported the British. Can you explain why?
Answer:
The policies of Zamindars created a gap between them and their people. They earned more assets in the British reign. So they normally supported the British during the freedom movement.

Question 17.
Who introduced the Permanent Settlement of Tax and when?
Answer:
Cornwallis introduced this in 1793.

Question 18.
Why did the war in America lead to increase in prices of cotton in India?
Answer:
In 1861, there was Civil war in America and British factories turned to India for supply of cotton. As a result cotton prices soared high.

Question 19.
Why were famines caused under British rule? Do you think it was because of failure of rains or floods?
Answer:
The rains and floods caused one or two famines during the British rule. Most of the famines occurred due to their dictatorial rule. They exported food grains in the famines. They had no interference when the merchants created artificial scarcity by hoarding food grains. They didn’t work for the welfare of the people in India. So the famines were caused.

Answer:
Temperature falls when we move from the equator to the poles.

Question 3.
Mention five points about the summer in Tundra. (Textbook Page No. 42)
Answer:

The Sun begins to shine in the tundra around February-March. In the beginning the Sunsets within a short time.
For almost three months from May to July, the Sun never sets.
The Sun does not rise overhead. It just hovers a little above the horizon. So it is never very warm.
Due to the relatively warm weather, some of the ice melts. The rivers, lakes melt and begin to flow.
When summer approaches, many multi-coloured plants, lichens, grass, shrubs and berries sprout around.

Question 4.
Fill in the blanks : (Textbook Page No. 42)
1. The Sun does not appear during the month of November, December and January.
2. At this time, the water freezes and the plants cover with the snow.

Question 5.
How do the people of Tundra get light in winter ? (Textbook Page No. 42)
Answer:
There will be no sunlight during the winter in the polar region. At this time, the light of stars
falls on the ice, reflects, and fills the region with bright colourful lights. These are known as ‘Aurora Borialisis’. During winter they get light with these Aurora borialisis, oil and fat lamps.
In what ways are the resources available in their surroundings used for making houses? (Textbook Page No. 45)

They use skins of animals and wood for tents.
They use logs and whale ribs in building round houses.
They form ice blocks (like bricks) and build domed houses.

Thus they use available resources in the surroundings.

Question 6.
Did you see any tree in the pictures on the previous page? (Textbook Page No. 42)
Answer:
No. Grass and small bushes are visible in the pictures given.

Question 7.
Look at the pictures in this chapter (The Polar Region). How has that dress and hunting changed? (Textbook Page No. 48)
Answer:
The people of the earlier times wore raw skins of animals. They are too heavy. They use the horns of animals, harpoons, sharp edged instruments to hunt.
In the modern times they wore designed caps, dresses which are light in weight. Guns occupied the place of traditional weapons.

Question 8.
Why do you think people probably always did not live in the Tundra region? (Textbook Page No. 43)
Answer:
There are no seasons or seasonal differences in tundras. They have likely temperatures and seasons. They face nominal summers. So they cannot cultivate crops here. They have no tasty foods and different kinds of foods. During winters the whole region becomes dark, deserted and desolate. So they did not live here throughout the year.

Question 9.
How is the house impacted by the climate? (Textbook Page No. 45)
Answer:
Their houses are called igloos. In summer, most Eskimos live in tents made of animal skins. In some areas, they made tents of wood and animal skins. They use logs and whale ribs also for this. They use stone slabs in some areas. Snow houses are made from blocks of packed snow, built into a dome. They build snow platforms for their sleep. As the area is covered with snow they cannot lay foundations and they cannot lead a settled life. Thus the house is impacted by the climate.

Question 10.
Do you think lives of people in Tundra have changed for better or worsened because of their interaction with outside world? Give reasons for your answer. (Textbook Page No. 48)
Answer:
The lives of people in Tundra have changed for better or worst both because of their interaction with the outside world.

The pattern of relations between the Eskimos and outsiders has been described as “boom and bust”. Waves of outsiders have brought brief periods of wealth, education, and employment. This was followed by periods of poverty and disorganisation. Peak periods have been those of whaling (1859 to 1910), the modern fur trade (1925 to about 1950), the building of military and defence bases (the mid-1950s), the building of urban centres (mid- 1960s), and oil exploration and development (the 1970s).

Each wave of activity has drawn the Eskimos into contact with different social and economic forces. The once isolated northlands have been opened up by air travel, highways, powerful modern ships, and satellite communications. These changes have produced great strains on the Eskimo way of life.

Question 5.
How many kinds of minerals are there? What are they?
Answer:
Environmentalists differentiate minerals into two kinds of resources-renewable and non-renewable. Renewable resources are those which can be regenerated like wood.
Most minerals are non-renewable. There is only a limited amount of these available on the earth. If we finish them then there will not be any more of it. These are called non-renewable sources of energy, e.g.: gold, coal, petroleum.

Question 8.
Appreciate the mineral resources of Andhra Pradesh.
Answer:
Mineral Resources of Andhra Pradesh:
Andhra Pradesh is very rich in mineral resources. It is a large producer of granites of various colours, Kadapa stones, etc., used in buildings. It also produces limestone and dolomite used in cement industry. Northern districts have large coal deposits (Kothagudem in Godavari valley) while the Krishna Godavari basin has great potential for mineral oil and gas. AP is historically known for its famous diamond mines too and some of the largest diamonds in the world were found here.

Question 9.
What are the sensitivities in obtaining minerals from mines?
Answer:
Most of the mining practices result in disturbing the surface area – it can mean cutting down forests, destroying fields and habitations, creating large pits or mounds. Mines also need large amounts of water to wash the minerals. This results in polluting the nearby rivers and water sources. This usually means that older use of the land cannot be continued and farmers or tribal people have to leave the land. Even people who live nearby face problems created by mining. At the same time mining employs a large number of people who come to live in nearby areas and build new townships. It thus provides livelihood for nearly ten lakh people in India and over one lakh people in Andhra Pradesh. The work of miners is also very hazardous, as they are constantly exposed to accidents besides breathing in poisonous substances which cause long term health damage.

Question 10.
What aspects of regulations in the mining by the government do you agree with? And why?
Answer:
If the government introduced sophisticated methods and technology instead of giving the mines on lease, I feel better.
The reasons are:

The private people may not take the safety measures.
Their attitudes may cause ‘0’ (zero) minerals to the future citizens.
The right percentage of royalty may not reach the government properly.
The unused mines may not be closed in view of expenditure.

So I support the government regulation only.

Question 11.
Why is the SCCL interested in open cast?
Answer:
When compared to underground mines, the open casts are less expensive. Machines can be used widely in these. So SCCL is interested in open casts.

Question 12.
Why is the mining of atomic fuels in the hands of government?
Answer:
Atomic fuels are most valuable. We have less reserves of them. They play a key role in our safety. So they are in the hands of government.

Question 13.
Why should the residents of mining areas be rehabilitated?
Answer:
The residents of mining areas are the owners of those lands. The lands are confiscated from them by force. So they should be rehabilitated.

Question 14.
Read a news report of 29 June 2009:

Sinqareni coal mines open wounds

By Our Correspondent
WARANGAL, June 28: Singareni Collieries Company Limited (SCCL) has decided to adopt Open Cast Mining (OCM), to meet the demand for coal. The decision could render 20,000 people homeless and affect 200 villages. The mines will also affect an estimated 3,000 hectares of forests.

“If the mining underground produces 1,500 tonnes of coal a day, open cast mines pro-duce 10,000 tonnes per day and obviously at a much lesser cost,” said a senior SCCL official.

While that is so, the open cast mining will displace thousands of families, destroy scores of habitations and cause loss of livelihood to locals. According to the company official, the company will pay compensatory afforestation charges and develop forests on an equal amount of land where it has lopped off the jungles. It will pay Rs. 4.38 to Rs. 10.43 lakh per hectare, he said. The local people also complained that due to these mines which dig up the earth and create huge artificial hills of loose earth, rivers and streams are getting choked and ground water is getting polluted and there is acute scarcity of even drinking water.
