Answer:
d
Explanation:
The climate of India has many
regional variations expressed in the pattern of winds, temperature and
rainfall, rhythm of seasons and the degree of wetness or dryness. These
regional diversities may be described as sub-types of monsoon climate.

Answer:
a
Explanation:
In Kerala and in the Andaman
Islands, the difference between day and night temperatures may be hardly seven
or eight degree Celsius. But in the Thar Desert, if the day temperature is
around 50°C, at night, it may drop down considerably upto 15°-20°C. Tawang
(Arunachal Pradesh) does not have extreme diurnal temperature.

Explanation:
While Cherrapunji and Mawsynram in
the Khasi Hills of Meghalaya receive rainfall over 1,080 cm in a year. Tura
situated in the Garo Hills of Meghalaya may receive an amount of rainfall in a
single day which is equal to 10 years of rainfall at Jaisalmer, Drass (Jammu
and Kashmir) experience very cold temperature in India.

Consider the following statements
1. North India completely lies in
subtropical zone while southern part lies in tropical zone.
2. Area North of Tropic of cancer experiences small daily and annual range of temperature compared to tropic of cancer.
2. Area North of Tropic of cancer experiences small daily and annual range of temperature compared to tropic of cancer.
Select
the correct answer from the following codes
a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
Answer:
d
Explanation:
the Tropic of Cancer passes through
the central part of India in east-west direction. Thus, northern part of the
India lies in sub-tropical and temperate zone and the part lying south of the
Tropic of Cancer falls in the tropical zone. The tropical zone being nearer to
the equator, experiences high temperatures throughout the year with small daily
and annual range. Area north of the Tropic of Cancer being away from the
equator, experiences extreme climate with high daily and annual range of
temperature.
5. Consider the following statements
1. Himalayas shield India from cold winds originating from Antarctic Circle and also trap monsoon winds.
2. Areas located on same latitude always have same temperature.

the correct answer from the following codes
a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
Answer:
d
Explanation:
The lofty Himalayas in the north
along with its extensions act as an effective climatic divide. The towering
mountain chain provides an invincible shield to protect the subcontinent from
the cold northern winds. These cold and chilly winds originate near the Arctic
Circle and blow across central and eastern Asia. The Himalayas also trap the
monsoon winds, forcing them to shed their moisture within the subcontinent.
6. Which of the following factors is/are influenced by relief of India?
6. Which of the following factors is/are influenced by relief of India?
1. Amount of rainfall but not
distribution of rainfall.
2. Air pressure
3. Speed of wind
2. Air pressure
3. Speed of wind
Select
the correct answer from the following codes
a.Only 1
b.Only 1 and 2
c.Only 2 and 3
d.1,2 and 3
b.Only 1 and 2
c.Only 2 and 3
d.1,2 and 3
Answer:
c
Explanation:
The physiography or relief of India
also affects the temperature, air pressure, direction and speed of wind and the
amount and distribution of rainfall. The windward sides of Western Ghats and
Assam receive high rainfall during June-September whereas the southern plateau
remains dry due to its leeward situation along the Western Ghats.
7. Which of the following factors cause difference in local climate of India?
7. Which of the following factors cause difference in local climate of India?
1. Jet Streams
2. Western Disturbances
3. Tropical depressions
2. Western Disturbances
3. Tropical depressions

a.Only 1
b.Only 1 and 2
c.Only 2 and 3
d.1,2 and 3
b.Only 1 and 2
c.Only 2 and 3
d.1,2 and 3
Answer:
d
Explanation:
the differences in local climates of
India, is influenced by following three factors:
(i) Distribution of air pressure and winds on the surface of the earth. (ii) Upper air circulation caused by factors controlling global weather and the inflow of different air masses and jet streams. (iii) Inflow of western cyclones generally known as disturbances during the winter season and tropical depressions during the south-west monsoon period into India, creating weather conditions favourable to rainfall.
8. Which of the following has below mentioned features?
(i) Distribution of air pressure and winds on the surface of the earth. (ii) Upper air circulation caused by factors controlling global weather and the inflow of different air masses and jet streams. (iii) Inflow of western cyclones generally known as disturbances during the winter season and tropical depressions during the south-west monsoon period into India, creating weather conditions favourable to rainfall.
8. Which of the following has below mentioned features?
1. It influences Central and
west Asia along 9-13 km altitude.
2. One part of it has important influence on winter weather.
3. It blows roughly parallel to Tibetian highlands
2. One part of it has important influence on winter weather.
3. It blows roughly parallel to Tibetian highlands
Select
the correct answer from the following codes
a.Western Disturbances
b.Jet Stream
c.Tropical Depression
d.Loo winds
b.Jet Stream
c.Tropical Depression
d.Loo winds
Answer:
b
Explanation:
All of Western and Central Asia remains
under the influence of westerly winds along the altitude of 9-13 km from west
to east. These winds blow across the Asian continent at latitudes north of the
Himalayas roughly parallel to the Tibetan highlands. These are known as
jet streams. Tibetan highlands act as a barrier in the path of these jet
streams. As a result, jet streams get bifurcated One of its branches blows to
the north of the Tibetan highlands, while the southern branch blows in an
eastward direction, south of the Himalayas. It is believed that this southern
branch of the jet stream exercises an important influence on the winter weather
in India.

Consider the following statements
1. Increase in night temperature indicates the arrival of western cyclonic disturbances.
2. Tropical cyclones that originate in Indian Ocean are brought to Bay of Bengal by westerly Jet stream.
1. Increase in night temperature indicates the arrival of western cyclonic disturbances.
2. Tropical cyclones that originate in Indian Ocean are brought to Bay of Bengal by westerly Jet stream.
Select
the correct answer from the following codes
a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
Answer:
a
Explanation: The western cyclonic disturbances which enter the
Indian subcontinent from the west and the northwest during the winter months
originate over the Mediterranean Sea and are brought into India by the westerly
jet stream. An increase in the prevailing night temperature generally indicates
an advance in the arrival of western cyclonic disturbances. Tropical cyclones
originate over the Bay of Bengal and the Indian Ocean.
10. Consider the following statements
1. ITCZ is zone of divergence located at equator which moves Northwards during summer.
2. ITCZ movement to the Indian Subcontinent in summer causes withdrawal of westerly jet stream.

2. ITCZ movement to the Indian Subcontinent in summer causes withdrawal of westerly jet stream.
Select
the correct answer from the following codes
a. Only 1
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
b. Only 2
c. Both 1 and 2
d. Neither 1 nor 2
Answer:
b
Explanation:
The Inter Tropical Convergence Zone
(ITCZ) is a low pressure zone located at the equator where trade winds
converge, and so, it is a zone where air tends to ascend. In July, the ITCZ is
located around 20°N-25°N latitudes (over the Gangetic plain), sometimes called
the monsoon trough. Meteorologists have found an interrelationship between the
northward shift of the equatorial trough (ITCZ) and the withdrawal of the
westerly jet stream from over the North Indian Plain. It is generally believed
that there is a cause and effect relationship between the two.
