Question 11.
What is the relation between the temperature of a location and insolation?
Answer:
The temperature of the atmosphere at a particular place near the Earth’s surface depends upon the insolation (heat from sun rays) received at that location. This is more intense in the low latitudes than in the high latitudes. As we move away from the equator towards the poles, the average annual temperature decreases.

Question 12.
Read the paragraph and answer the question that follows.
“In India, the southern part lies in the tropical belt closer to the equator. There-fore this region has higher average temperature than the northern part, this is one reason for the climate of Kanyakumari being entirely different from Bhopal or Delhi, India is situated roughly between 8° and 37PN latitudes and the country is divided into almost two equal parts by the Tropic of Cancer. The part south of the Tropic of Cancer lies in the tropical tone. The part north of the Tropic of Cancer lies in the temperate zone.”
Why is the climate of Kanyakumari being entirely different from Bhopal or Delhi?
Answer:
In India the southern part lies in the tropical belt closer to the equator. Therefore this region has a higher average temperature than the northern part. This is one reason for the climate of Kanyakumari being entirely different from Bhopal or Delhi.

Question 13.
Explain the latitudinal extent of India.
Answer:
India is situated roughly between 8° and 37° N latitudes and the country is divided into almost two equal parts by the Tropic of Cancer. The part south of the Tropic of Cancer lies in the tropical zone. The part north of the Tropic of Cancer lies in the temperate zone.

Question 14.

Answer:
Cyclone depressions coming from Mediterranean Sea called Western Disturbances and cause low to moderate rainfall over northern India. This rainfall is boon to the wheat crop which is generally cultivated in ‘Rabi’ season.

AP SSC 10th Class Social Studies Important Questions Chapter 4 Climate of India

Question 15.
What is the effect of north-east trades on India?
Answer:
India lies in the trade wind belt of Northern Hemisphere – north-east trades blow over India from land to sea and are therefore dry. However, some amount of rainfall occurs on the Coromandel coast of Tamil Nadu from these winds, as they pick up moisture from the Bay of Bengal while crossing it.

Question 16.
Write about ‘mango showers’ in Andhra Pradesh?
Answer:
Towards the end of the summer season, pre-monsoon showers (‘bursting monsoon’) are common in the Deccan Plateau. These help in the early ripening of mangoes and other plantation crops in peninsular India. Hence they are locally known as mango showers in Andhra Pradesh.

Question 17.
What is known as “Onset of monsoon”?
Answer:
The Arabian Sea branch arrives at the west coast of India and moves northward. Both the Arabian Sea and Bay of Bengal branches reach India by the beginning of June, which is known as ’Onset of monsoon1.

Question 18.
What is known as “October heat”?
Answer:
October-November is a period of transition from a hot wet condition to dry winter condition. The retreat of the monsoons is marked by clear skies and rise in temperature. The land is still moist. Owing to the con¬ditions of high temperature and humidity, the weather becomes rather oppressive. This is commonly known as October heat.

AP SSC 10th Class Social Studies Important Questions Chapter 4 Climate of India

Question 19.
Write about the Indian traditional seasons.
Answer:
In the Indian tradition, a year is divided into six two-monthly seasons. This cycle of seasons that the people in north and central India follow is based on their practical experience and age-old perception of weather phenomena. There is a slight variation in the timing of the seasons between northern and southern India.
The seasons are

  1. Vasantha
  2. Grishma
  3. Varsha
  4. Sharad
  5. Hemantha
  6. Shishira.

Question 20.
What is called Greenhouse effect?
Answer:
Keeping us warm is one of the most impor¬tant things that the atmosphere does for us.
It is like a light, but effective, blanket envelo¬ping Earth. The atmosphere traps a lot of the solar energy that reaches. Earth by preventing it from totally escaping back into space. This is called the Greenhouse effect.

Question 21.
What is called AGW?
Answer:
Earlier cycles of cooling and warming happened over very long periods of time. This allowed much of the life on Earth the time to adapt to the changes. The problem now is that the heating is much more rapid and could lead to catastrophic changes. Much of the warming that has been occurring since the Industrial Revolution is because of human activities. Hence, the current global warming trend is called AGW (Anthropo-genic Global Warming anthropogenic means caused by humans).

Question 22.
What does climate refer to?
Answer:
Climate refers to such conditions over a large area and follows a similar general pattern over many years. What has been the general conditions, year after year, over thirty years or more, gives us the climate.

Question 23.
Explain the word ‘monsoon’.
Answer:
The climate of India is strongly influenced by the monsoon winds. The sailors who came to India during olden days noticed the regular periodic reversal of winds. They used these winds to sail towards the Indian coast. Arab traders named this seasonal reversal of wind system ‘monsoon’.

Question 4.
Developed countries want developing countries to cut down on burning coal and other activities that add greenhouse gases to the atmosphere. Is this justified? Explain your opinion.
Answer:
This is justified because activities that increase greenhouse gases are increased. The net effect is that these gases lead to the depletion of the ozone layer in the upper atmosphere.
When the ozone layer is depleted what happens is that radiation pertaining to ultraviolet rays reaches the earth’s surface and this radiation may cause cancer.
OR
It is not justified because

  1. Developing countries argue that the developed countries have developed by burning fossil fuels.
  2. They also argue that they cannot develop without burning fossil fuels.
  3. They also want the developed countries to show alternative sources for their development.

Question 6.
Read the following paragraph and write your comments.
Most scientists from around the world agree on this much: AGW (Anthropogenic Global Warming; anthropogenic means caused by humans) is real, it is happening, and it is leading to rapid and drastic climate change. They warn that severe weather and other changes will increase in the coming years and threaten life as we know it.
Answer:
Global warming: It refers to an unequivocal and continuing rise in the average temperature of Earth’s climate system.
Human activities contributing to global warming:

  1. Human activities contribute to climate change by causing changes in Earth’s atmosphere in the amount of greenhouse gases, aerosols and cloudliness.
  2. The largest known contribution comes from the burning of fossil fuels, which releases carbon dioxide gas to the atmosphere.
  3. Greenhouse gases and aerosols effect climate by altering incoming solar radiation and out going infrared radiation that are part of Earth’s energy balance.
  4. Due to industrial revolution, industrial pollution increases day by day.
  5. Increasing of over population and using of power driven vehicles.
  6. New methods of agricultural practices.
  7. Mining, the establishment of nuclear power plants and reckless deforestation, etc.

Evil effects of global warming:

  1. The earlier changes of cooling and warming are more rapid and leading to catastrophic changes.
  2. If the climate is raised by 2° C, it leads to one meter raise in the sea levels.
  3. The faster melting of Himalayan glaciers would disturb the livelihood of fisher folk.

Measures to minimize the influence of the global warming:

  1. Afforestation
  2. Reduction of burning of fossil fuels.
  3. Instead of coal use of solar energy to be encouraged.
  4. Reduction in the use of vehicles and encouragement of public transport system.
  5. Release of greenhouse gases into the atmosphere should be reduced.

Question 7.

Answer:
The factors that affect climate are called climatic controls. These include:

  1. Latitude
  2. Land-water relationship
  3. Relief
  4. Upper air circulation

1. Latitude:

  1. Intensity of temperature depends on the latitude. It is more intense in lower latitudes than at higher latitudes.
  2. In India, the southern part lies in the tropical zone, closer to the equator; it has a higher average temperature than that in the northern part.
    Ex: The climate of Kanyakumari is different from that of Delhi.

2. Land-water relationship:

  1. The water bodies absorb and lose heat more slowly than land.
  2. Due to this the formation of land and sea breezes influence the climate of coastal region. Ex: As Visakhapatnam is on the seashore, it is cooler than Guntur which is not on the seashore.

Question 9.
Classify the monsoon winds in India and explain them.
Answer:

Monsoon winds

Climate of country is determined by various factors like Latitude, Relief, Land water relationship and upper air circulation. Climate in India is influenced by monsoons. The Arab traders named the term monsoon. The monsoons in the tropical area are strong as low pressure forms here. The Southeast monsoon winds from the Southern hemisphere carry moisture as they flow over the Indian ocean and towards the equatorial low-pressure zones.
After crossing the equator, these winds deflect towards the low pressure formed in the Indian sub-continent. The heating of land creates low pressure on the land mass of Indian sub-conti¬nent, especially over central India and the Gangetic plain. Along with this, the Tibetan plateau gets intensely heated and causes strong vertical air currents and the formation of low pressure over the plateau at above 9 kms altitude.

They then flow as the southwest monsoon. The Indian peninsula divides them into two branches – the Arabian Sea branch and the Bay of Bengal branch. The Bay of Bengal branch strikes the Bengal coast and the southern face of the Shillong plateau. Then, it gets deflected and flows westward along the Gangetic valley. The Arabian Sea branch arrives at the west coast of India and moves north ward. Both the branches reach India by the beginning of June, which is known as the ‘onset of monsoon’. They gradually spread over the entire country in four to five weeks. The bulk of annual rainfall in India is received from south-west monsoon. The amount of rainfall is very high along the west coast due to the Western ghats, and in north-east India due to the high peaked hills. Tamil Nadu coast (Coromandel), however, remains mostly dry during this season as it is in the rain shadow area of the Arabian Sea branch and is parallel to the Bay of Bengal branch.

The low pressure conditions which once prevailed over north-western India move far South to the centre of the Bay of Bengal by early November. During this period,cyclonic depressions are common which originate over the Andaman area. These tropical cyclones are often very destruc¬tive. The thickly populated deltas of the Godavari, Krishna and Cauveri are their targets. No year ever goes disaster-free. Occasionally, these tropical cyclones visit Sundarbans and Bangladesh too. Bulk of the rainfall of the Coramandel Coast is derived from depressions and cyclones.

Question 14.
Read the following text and interpret it.
More recently, scientists are discovering large volumes of methane under the frozen tundras of the far northern latitudes (mainly in the vast expanses of northern Russia). As global tem¬perature increases, the ice in the tundra melts more. The methane that is trapped under the ice escapes into the atmosphere, increasing the global temperatures. In turn, this causes even more ice to melt, releasing even more methane, and so on. Methane is said to be even more powerful than carbon dioxide as a greenhouse gas.
Answer:
