Total Questions: 50

31. Match List-I with List-II and select the correct answer using the codes given below:

List-I (Soils)	List-II (Climatic region)
A. Podzol	1. Temperate grass lands
B. Chernozem	2. Cool temperate
C. Spodsols	3. Hot and humid
D. Laterite	4. Humid cool temperate

Codes:

	A	B	C	D
(a)	2	1	3	3
(b)	3	4	2	1
(c)	2	3	4	1
(d)	4	1	3	2

Correct Answer: (a)

Solution:Podzols are subarctic soils of the cold, humid northern coniferous forest (taiga), found between the mixed forests of the temperate zone and the tundras of the arctic zone. Chernozem is a black-coloured soil containing a high percentage of humus (7% to 15%), and high percentages of phosphoric acids, phosphorus and ammonia.

Chernozem is very fertile and produces a high agricultural yield. Chernozem soils are found in humus rich grasslands such as in Prairies, Pampa and Steppes. Spodsols soils develop under coniferous vegetation. Laterite. soils are found in hot and humid areas.

32. Which is the largest riverine Islands of the World?

(a) Majuli Island in Brahmaputra River in Assam
(b) Marajo Island in Amazon River in Brazil
(c) Tupinambarana Island in Amazon River in Brazil
(d) Boven Digul Island in Digul River in Indonesia

Correct Answer: (a) Majuli Island in Brahmaputra River in Assam

Solution:Majuli Island in Brahmaputra River in Assam is the largest riverine Islands of the world.

33. Stromboli is a/an-

(a) dormant volcano
(b) active volcano
(c) extinct volcano
(d) None of the above

Correct Answer: (b) active volcano

Solution:Stromboli is one of the most active volcanoes on Earth and has been erupting almost continuously since 1932. It is also known as the 'Lighthouse of the Mediterranean'.

34. Global warning during winter becomes more pronounced at the :

(a) Equator
(b) Poles
(c) Tropic of Cancer
(d) Tropic of Capricorn

Correct Answer: (d) Tropic of Capricorn

Solution:Since the Tropic of Capricorn is the circle of latitude that contains the subsolar point on the December (or southern) solstice, it is the southernmost latitude where the Sun can be directly overhead. Its northern equivalent is the Tropic of Cancer. Hence, global warming during winter becomes more pronounced at the Tropic of Capricorn.

35. Consider the following statements about our country India:

I. India has an area of about 3.28 million sq. km.

II. India is located in the south-eastern hemisphere.

III. The latitudinal extent of India is 8°4'N and 37° 6'N latitudes.

IV. The longitudinal extent of India is 68°7'E and 97° 25' E longitudes.

Of these statements:

(a) Only I is correct
(b) I, II and III are correct
(c) Only III and IV are correct
(d) I, III and IV are correct

Correct Answer: (d) I, III and IV are correct

Solution:India is located in eastern part of Northern hemisphere.

36. Which of the following statements regarding south-west monsoon in India is/are correct?

I. Monsoon reaches the Malabar coast first

II. Rajasthan does not get rainfall from south west monsoon

III. South-west monsoon retreats when the permanent wind belts start shifting to the south

Select the correct answer using the code given below :

(a) I, II and III
(b) I and II only
(c) III only
(d) I and III only

Correct Answer: (a) I, II and III

Solution:The southwest monsoon brings rains towards the end of summer as the high pressure built in the Indian Ocean pushes the wind masses towards the low pressure formed on land.

It's the temperature variation between the sea and the landmass - sea air being cooler and land being warmer - that causes the action. Also, we have to take an important factor called Temperature Gradient into consideration. It is the Temperature Variation Between The landmass and: the surrounding sea.

37. Consider the following statements

The South-West monsoon originates in India due to
1. low pressure in the Punjab plain.
2. high pressure in areas South of India.
3. equatorial low being filled up by descending air current.
4. the Himalayas.

Which of the statements given above are correct?

(a) 1 and 4
(b) 1 and 2
(c) 1 and 3
(d) 2 and 4

Correct Answer: (a) 1 and 4

Solution:The southwest monsoon brings rains towards the end of summer as the high pressure built in the Indian Ocean pushes the wind masses towards the low pressure formed on land. The southwestern summer monsoons occur from July through September.

Northern and central Indian subcontinent heats up during the hot summers. This causes a low pressure area over the northern and central Indian subcontinent. To fill this void, the moisture-laden winds from the Indian Ocean rush in to the subcontinent.

These winds, rich in moisture, are drawn towards the Himalayas. The Himalayas act like a high wall, blocking the winds from passing into Central Asia and forcing them to rise. As the clouds rise their temperature drops and precipitation occurs.

38. What would be the influence on the weather conditions when in mid-winter a feeble high pressure develops over the North-Western part of India?

1. High and dry winds would blow outward from this high pressure area.

2. The Northern plain would become cold.

3. Scorching winds (locally called loo) would blow during the day time.

4. There would be torrential rains brought by thunderstorms.

Select the correct answer using the codes given below.

(a) 1 and 2
(b) 2 and 3
(c) 3 and 4
(d) All of these

Correct Answer: (a) 1 and 2

39. Consider the following statements:

1. Crystallization is a form of mechanical weathering.

2. Hydration causes granular disintegration.

3. Frost action is synonymous with freeze-thaw action.

Which of the statements given above are correct?

(a) 1 and 2 only
(b) 2 and 3 only
(c) 1 and 3 only
(d) 1, 2 and 3

Correct Answer: (d) 1, 2 and 3

Solution:Crystallisation is a form of mechanical weathering. It is operative especially in arid climates. Due to dry weather, moisture is drawn to the surface of rocks. Hydration is another process which involves water, but there is no chemical change whatsoever. Hydration causes granular disintegration. Frost action is also termed as synonymous with freeze-thaw action.
